How does ultrasonic atomization spraying applicated in energy field?

Principles

超声波机箱将市电转为高频电能，高频电能到达换能器时，被换能器转化为同频率的振动机械能，振动的机械能将液体打碎成UM级的雾滴。

    When the high frequency electric energy reaches the transducer, it is transformed into vibration mechanical energy of the same frequency. The vibration mechanical energy breaks the liquid into UM droplets.

    At present, the frequency of 60Khz is dominant in the field of energy application.

Superiority of ultrasonic atomization:

1.减少浪费

1. Reduce waste

2.雾化均匀

2. Atomization uniformity

3.涂层厚薄可控

3. Controllable Coating Thickness

4.不易阻塞

4. Not easy to block

Energy application

I. Photovoltaic Cells

太阳能光伏电池(简称光伏电池)用于把太阳的光能直接转化为电能。光伏电池的结构主要为

Solar photovoltaic cells (PV cells) are used to convert solar energy directly into electrical energy. The structure of photovoltaic cells is mainly as follows:

1. 基底 2铁 3.活性层/缓冲层  4.TCO导电涂层

1. Base  2 Fe  3. Active Layer/Buffer Layer  4. TCO Conductive Coating

超声波主要负责喷涂活性层/缓冲层和TCO层。

Ultrasonic is mainly responsible for spraying active layer/buffer layer and TCO layer.

活性层/缓冲层：主要物质为CIS、CIGS、CDTE、CZTS、DSC等光伏有机化合物。这些光伏化合物参与光伏反应。

Active Layer/Buffer Layer: The main substances are CIS, CIGS, CDTE, CZTS, DSC and other photovoltaic organic compounds. These photovoltaic compounds are involved in photovoltaic reactions.

Superiority of ultrasonic: Each layer of these substances is uniformly coated. Ultrasound has better uniformity than high pressure injection.

TCO Layer: Because the photovoltaic organic compounds in the active layer/buffer layer are not conductive, the TCO coating can collect current because of its excellent conductivity.

Superiority of ultrasonic: TCO coating liquid is expensive, traditional high pressure spraying will sputter. In the process of ultrasonic spraying, almost no liquid will be sputtered, which effectively reduces the waste of liquid.

II. Fuel Cells

Fuel cell is a kind of power generation device which converts chemical energy existing in fuel and oxide into electric energy.

超声波主要负责喷涂燃料电池的PEM催化剂层和GDL气体扩散层。

Ultrasonic is mainly responsible for spraying PEM catalyst layer and GDL gas diffusion layer of fuel cell.

从结构图中我们可以看到催化剂层在气体扩散层内部。

From the structure diagram, we can see that the catalyst layer is inside the gas diffusion layer.

PEM:PEM催化剂的作用主要是加速催化燃料和氧化物的反应。它的主要含量是铂,铂是稀有金属,有限资源，价格相对比较昂贵，目前控制燃料电池的厚度为20-37um。

PEM: The main function of PEM catalyst is to accelerate the reaction of fuel and oxide. Its main content is platinum, platinum is a rare metal, limited resources, relatively expensive, the current control of fuel cell thickness of 20-37um.

GDL: GDL gas diffusion layer mainly supports catalyst layer and ventilation and drainage. The thickness of GDL gas diffusion layer is required in the range of 100um-400um.

Superiority of ultrasonic: Compared with high pressure spraying, ultrasonic can control the thickness of coating and make the coating thickness meet the standard requirements.
