HEAT EXCHANGER, COLOR WHEEL HEAT EXCHANGE SYSTEM AND PROJECTION DEVICE

摘要

A heat exchanger (100). A free end of a lateral plate (202) of the heat exchanger (100) in the second direction goes beyond a third surface of a heat exchange core body (204), and connecting holes (2021) are formed on the lateral plate (202) so that the lateral plate (202) can directly serve as a mounting plate of the heat exchanger (100); two lateral plates (202) are respectively connected to a first water tank (201) and a second water tank (203), and can serve as a frame of the heat exchanger (100) to improve the overall mounting strength of the heat exchanger (100); and moreover, the heat exchange core body (204) is connected to the water tanks, thereby reducing the welding parts and welding step of the heat exchanger (100), improving the welding yield, reducing the weight of the heat exchanger (100), and reducing the cost, and thus the user experience is good.
