Description

technical field

[0001] The invention relates to a heat exchange device and a manufacturing process thereof. Background technique

[0002] At present, the structure of the heat source part of the heat exchanger commonly used for heat exchange generally adopts a circular straight tube or a spiral tube. The contact area between the heat source tube wall and the heated fluid is small, and the heat load is low; the heat source tube wall is thicker, and the inner wall and the heated fluid The temperature difference of the outer wall is large, the heat transfer rate is low, the heat loss is large, the heat exchange rate is not high, and the demand for the heat source is large, resulting in a bulky heat exchanger, high manufacturing cost, and limited application range. Contents of the invention

[0003] The purpose of the present invention is to overcome the above disadvantages and provide a new core tube heat exchang...
