Influence of EV AIR COOLER Inclined Surface Arrangement and Heat Transfer Effect


The EV AIR COOLER mainly uses air to cool the heat exchanger of the heat flow. The heat flow in the equipment pipeline mainly exchanges heat with the air outside the pipeline through the pipe wall and the heat sink, and is generally provided by the fan during use.

EV AIR COOLER mainly includes ventilator and other components in the manufacturing process. To some extent, it can be divided into three basic forms: horizontal, vertical and inclined. When working, the horizontally arranged heat transfer area is large, the airflow distribution is uniform, and the heat transfer effect is good.
To a certain extent, air coolers can be directly used for cooling or condensing, and are widely used to cool various circulating air and exhaust air of condensing units during operation. The operating pressure reaches 69 MPa. However, climate change has a great impact on its cooling effect, the noise is large, and the resulting cooling effect is also great.
When the air cooler is arranged on a sloping top, the ventilation unit is effectively installed in the chevron-shaped central space. The whole machine occupies a small area and has a compact structure. During operation, in order to offset the influence of low thermal coefficient on the air side, a finned tube with an outer wall of a light tube is often used.
The finned tubes of EV AIR COOLER function as heat exchange tubes to a certain extent, which can effectively expand the heat exchange area. The finned tubes are arranged in layers, and the two ends of the finned tubes are connected to the tube box by welding or expansion joints. This is usually the case with exhaust pipes in rows 3-8. The diameter of the tube bundle can reach 12 meters.
The form and material of EV AIR COOLER's core components directly affect device performance. Tubes can be made of carbon steel, copper, aluminum and stainless steel, depending on the usage environment and manufacturing process to determine the fin material. Most use industrial pure aluminum, and copper or stainless steel are also used when corrosion resistance or special manufacturing process conditions are required. The fins can be arranged horizontally or vertically. There are three main types of shell-and-tube structures: flanged, plugged and collector. Usually the former is medium and low pressure, and the latter is high pressure.
