这Cooling Fan Selection Process

Step 1: Perform a Thermal Analysis

这first step in the cooling fan selection process is performing a thermal analysis. A thermal analysis determines the amount of heat generated inside a particular piece of equipment or during a particular process. The result can be used to calculate the volume of air needed to cool the device or system.

这rmal analysis operations use sensors and other instruments to determine the source(s) of heat and the amount of heat generated by each source. The heaviest consumers of power and, consequently, the biggest contributors to heat dissipation are often components like microcontrollers, processors, FPGAs, and MOSFETs. Once the necessary information is obtained, the amount of airflow required to cool the device or system can be calculated. Afterward, the cooling air path can be mapped using sensors and software to ensure that all major heat sources receive the air needed to cool them sufficiently.

Step 2: Determine the System Impedance

进行热分析并计算所需的空气体积后，冷却风扇选择过程的下一步是确定系统阻抗。188体育在线官方188d金宝搏的网址系统阻抗是指随着风扇的入口通风孔和排气通风口之间的空气行驶时所经历的压降的总和。如果系统具有多个空气路径，则添加单个阻抗值。可以通过压力传感器或将系统放入空气室中的不同气流速率来测量该值。

步骤3:选择风机的类型

After the system impedance is identified, it can be used with the calculated airflow requirement to gauge the static pressure needed for the system. This information can then be utilized to determine which fan will serve as the best solution.

188d金宝搏的网址188体育在线官方金宝搏188是什么公司根据空气流过它们的方式，冷却风扇分为两类。

• 轴向fanshave air enter and exit in the same plane. Similar to an airplane propeller, they have blades that generate aerodynamic lift and pressurize the air. They can provide high airflow and are ideal for applications involving relatively low static pressure.
• Centrifugal fans让空气进入一架飞机，然后退出另一个飞机。他们具有旋转的叶轮，其叶片会增加空气流的速度并将其转化为压力。它们可以产生高压力，适合涉及恶劣条件（例如潮湿或肮脏的气流）的应用。

在这两个粉丝设计之间选择时要考虑的一些因素是：

• Pressure
• Airflow rate
• 效率率
• 空间约束
• Noise generation
• 驱动器配置
• 工作温度范围
• Operating environment range
• Cost
• Delivery time
• Availability

步骤4：最终考虑

除上述内容外，选择系统的冷却风扇时要记住的其他考虑因素包括：188体育在线官方188d金宝搏的网址

• 集成速度控制：以快速速度连续运行的粉丝将很快磨损。Integrating speed control elementsthat alter the speed of the fan when needed can significantly increase the overall service life of a unit.
• Incorporating performance monitoring circuits:Performance monitoring circuits track fan performance to identify potential malfunctions before they occur.
• 建立维护时间表/程序：无论您选择哪种风扇，都必须为其创建和实施维护时间表。否则，该设备可能会意外分解。基本的维护程序应涵盖以下内容：轴承，皮带和滑轮，泄漏，运动状况和系统清洁。

A fan is a key component of any HVAC system. The most common HVAC fans are axial, forward-curved centrifugal, and backward-inclined, and each is uniquely suited to certain purposes. It’s important to understand each fan’s differences in energy efficiency, cost-effectiveness, and noise considerations. The wrong fan for the job could lead to reduced functionality and higher costs. Here’s what you need to know about the various fans for HVAC systems.

轴向风扇

轴向风扇，其中包括螺旋桨，管轴向和叶片轴向样式，沿风扇轴移动空气流。这些风扇像飞机螺旋桨一样工作 - 布莱斯产生了空气动力的升降机，然后将空气加压。螺旋桨风扇仅体现用于驱动气流的电动机和螺旋桨。与螺旋桨风扇类似，管子轴向风扇包括围绕风扇螺旋桨的文丘里（Venturi），旨在减少空气泄漏

旋转道具创建的年龄或涡流。叶片轴向风扇具有叶片，落后于螺旋桨的后部，该叶片伸直了当电动机加速空气时发生的旋转气流。轴向风扇便宜，紧凑且光线，使它们成为工业应用的最爱。但是，它们通常比离心粉丝更嘈杂。可以通过绝缘管道来减轻噪声；将风扇安装在橡胶等软材料上，或使用弹簧隔离器来减少透射振动的量；或安装声音阻尼材料或挡板。

离心粉丝

离心粉丝，，，，which are categorized by their radial, forward curved, or backward inclined blade shapes, increase the speed of an air stream with a rotating impeller. The speed increases as the air reaches the ends of the blades and is then converted to pressure. These fans are able to produce high pressures, which makes them suitable for harsh operating conditions, such as systems with high temperatures or moist or dirty air streams. Tip vortices or tip leakage flow produced by the pressure differential across the airfoil section can be problematic with these basic fans.

Forward-Curved Centrifugal Fans，，，，look more like hamster wheels and can create more air pressure. Because of this, they tend to be noisier than axial fans and require more power to run. They are durable, easy to clean and maintain, and have less problems with resistance. Forward-curved centrifugal fans are also called blowers.

向后弯曲的离心粉丝are uncommonly shaped blades, which can be curved or straight, make these fans excellent for high volumes of airflow and variable resistance. They are often used for industrial purposes.

粉丝类型的应用

Though axial fans are usually the least expensive, they’re not the right solution for every situation. Because of their features and capabilities, they are best for compact electronics, automotive products, medical devices, and appliances as well as large applications such as cooling towers, vending machines, outdoor air conditioner compressors, and combustion engine cooling. Axial fans are also ideal as general-purpose fans.

Centrifugal fans are better for larger systems: air-handling units, air pollution and filtration systems, and drying systems. With incredible energy efficiency and versatility, these fans come in a variety of models, so you can find one to fit into a small, hard-to-reach space. They are also great options for dust collection, glass tempering, and incineration systems.

Choosing the right fan for your HVAC system is essential for its efficiency and performance. An axial fan, for example, won’t do as good a job managing the resistance compared to centrifugal fans of the same size in an air filtration system. Using an axial fan for that purpose would make the system perform poorly and likely lead to extra maintenance and repairs. Even though it would be less expensive initially, it would cost you more in the long run and would not function the way you would expect from such a system. Likewise, using a centrifugal fan in a cooling tower where it’s not needed would lead to unnecessary noise and increased costs.

轴向vs Centrifugal Fans

风扇有两个主要品种，axial fans和离心粉丝。金宝搏官网mg金宝搏官网粉丝技术的全球领导者Pelonis Technologies，Inc。（PTI）已有25年以上的历史，生产了轴向和离心风扇。

To help clear up that confusion, here is a breakdown of the fan types, their benefits, and their uses.

这design and function of a centrifugal fan is very different from those of an axial fan. Their differences make them each suited for different applications and customers are sometimes unclear as to which fan type will best suit their needs.

轴向风扇

轴向风扇可以追溯到中世纪的欧洲水平配置的风车。1880年代推出的第一批电力风扇是轴向风扇。

轴向风扇以其创建的气流方向命名。围绕轴旋转的叶片与该轴平行地拉动空气，并朝着相同的方向迫使空气驶出。

轴向fans create airflow with a high flow rate, meaning they create a large volume of airflow. However, the airflows they create are of low pressure. They require a low power input for operation.

离心粉丝

这离心风扇was invented in 1832 by military engineer Lieutenant General Alexander Sablukov of the Russian Empire’s Imperial Russian Army.

Often called blowers, centrifugal fans vary differently from axial fans. The pressure of an incoming airstream is increased by a fan wheel, a series of blades mounted on a circular hub. Centrifugal fans move air radially — the direction of the outward flowing air is changed, usually by 90°, from the direction of the incoming air.

这airflow created by centrifugal fans is directed through a system of ducts or tubes. This helps create a higher pressureairflow比轴向粉丝。尽管流速较低，但离心风扇比轴向风扇创造了更稳定的空气流动。离心风扇还需要更高的功率输入。

风扇应用

轴向

Because of the low-pressure high-volume airflows they create, axial fans are best suited for general purpose applications. For example, they excel at moving air from one place to another,188体育在线官方诸如计算机之类的密闭空间，并冷却较大的空间，例如工作空间。188体育在线官方188d金宝搏的网址

标准AC模型是节能的，高速时使用不超过100瓦。AC风扇可以直接连接到直流电源，例如太阳能电池板或电池。由于自动售货机等单元中的最终目标是均匀的冷却能力，因此AC风扇是相当明显的选择。188体育在线官方188d金宝搏的网址

目前，自动贩卖行业领导者正试图使新一代对他们的服务感到兴奋。随着新的，髋关节人群的成长，他们的技术依恋，该行业正在寻找引起他们注意的新的令人兴奋的方法。

Cashless payment options, touch screens, and cell phone payment options are all becoming a part of the vending machine design. Companies like Intel® and Cisco Systems® are getting involved, which means the vending machine now has more and more in common with a computer.

就像您在办公室中可能拥有的任何计算机一样，对所有这些技术都包含在新设计中的所有这些技术都更加关注。

要求的技术特性,你可以看到a drop-off in performance due to heat. AC fans are an excellent choice to maintain just the right amount of cooling for these components.

出于所有这些原因，我们创建了PM1225-7系列轴向交流风扇。轴向交流fans在自动售货机中广泛使用，以提供机箱空间受到限制的冷却。188体育在线官方188d金宝搏的网址

Centrifugal

由于它们产生的高压，离心风扇是干燥和空调系统等高压应用的理想选择。由于它们所有的运动部件都被封闭，并且还具有颗粒性的还原性能，使其非常适合用于空气污染和过滤系统。离心粉丝还提供了独特的好处：

• First-rate energy efficiency。恒定的气流使离心风扇能够产生高达84％静态效率的能量。这些较高的效率水平是维持较大空气系统的理想选择。

• Enhanced durability.这些风扇足够耐用，可以在最腐蚀和侵蚀性的环境中正确运行。

• 限制超载的能力。某些离心风扇配备了非载荷马力曲线willensure the motor will not overload if its capacity is exceeded.

• Easy to maintain.Lighter material fans can be easily cleaned when you deem it necessary. Moreover, certain fans have self-cleaning characteristics, making daily maintenance that much easier.

• 高通用性。离心风机是有用的为多个气流/ pressure combinations, and they can process several airflow conditions, including clean, dry, and wet air

• Multiple sizes.这se fans are available in several sizes to accommodate diverse applications—such as those found in tight spaces or difficult to reach areas.
