Embodiment 1
[0041] According to the first object of the present invention, this embodiment provides a finned heat exchanger, such as Figure 2-7 As shown, it includes a set of fins and two heat exchange tubes, and the set of fins is composed of several fins 3 arranged in parallel and at a certain distance from each other. The heat exchange tube is one of aluminum tubes, copper tubes, and steel tubes, and its cross-sectional shape can be round, square, or oval, which can be selected according to different working environments and different needs. In this embodiment, it is a round aluminum tube . The two heat exchange tubes are the first heat exchange tube 1 and the second heat exchange tube 2 respectively, and each of the heat exchange tubes is bent and formed integrally. The U-shaped surface is defined as the reference surface, and after a certain distance from the bottom of the U-shaped opening along the U-shaped opening extension direction, it is bent upwards at an angle a relative to ...
Embodiment 2
[0046] This embodiment is the result of replacing it on the basis of embodiment 1. Such as Figure 8 As shown, the connector is a U-shaped connecting pipe 8, and the inlet of the first heat exchange tube 1 and the outlet of the second heat exchange tube 2 communicate through the U-shaped connecting pipe 8 to form a single-pipe refrigeration pipeline , which effectively increases the length of the refrigeration pipeline and improves the heat exchange efficiency.
Embodiment 3
[0048] This embodiment is the result of replacing it on the basis of embodiment 1. Such as Figure 9 As shown, the first heat exchange tube 1 and the second heat exchange tube 2 are independent of each other and serve as refrigeration pipelines of two sub-refrigeration systems respectively. In the same space, the refrigeration system is equipped with two independent sub-refrigeration systems. On the one hand, you can choose to start refrigeration at the same time to increase the cooling speed of the product; or only choose one of them to start refrigeration according to the actual situation to achieve energy saving; When one of the sub-refrigeration systems fails, the other can ensure the continuation of refrigeration, improving the reliability of the entire refrigeration system.
