Technical Field

It is also one of the main equipment for improving energy utilization. In order to meet the normal operation of the EMU, it is usually necessary to install multiple heat exchangers on the EMU for energy exchange in the EMU, to provide guarantee for the operation of the EMU and the drinking water and heating of passengers.

The outer edge of the heat exchanger body is provided with two layers of flanges, and an installation groove is formed between the two layers of flanges for facilitating the installation of the heat exchanger body.

In actual use, the high-temperature liquid is usually transported to the inside of the device through a water supply network and heating equipment. The efficiency of heat transfer in the heating pipeline often decreases with the increase of distance, making it difficult to effectively improve the energy utilization efficiency of the device.
