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.

Abstract

The invention relates to the technical field of refrigeration, and discloses a finned heat exchanger and refrigeration equipment. The finned heat exchanger comprises a fin group and a plurality of heat exchange pipes, wherein each fin is provided with a first through hole and a second through hole, each heat exchange pipe is integrally bent and formed, the plurality of heat exchange pipes penetrate through the first through holes and the second through holes from the left sides or the right sides of the fins, and the rest plurality of heat exchange pipes oppositely penetrate through the secondthrough holes from the right sides or the left sides of the fins; and the sum of pipelines of the heat exchange pipes which need to penetrate through the first through holes and the second through holes at the same time is one more plane layer than the sum of pipelines of the heat exchange pipes which only need to penetrate through the second through holes, and the heat exchange pipes are independent of one another or communicate with one another through connecting pieces. According to the finned heat exchanger and the refrigeration equipment, the holes are additionally formed in the basis oforiginal fins, the multiple heat exchange pipes reversely penetrate through the two sides of the fins to form crossed or staggered pipeline arrangement, the pipeline arrangement rate in a limited space is increased, and the problem of how to increase the heat exchange area of the finned type heat exchanger in the limited space is effectively solved; and meanwhile, the inlet and outlet connectionmodes of the heat exchange pipes can be flexibly selected according to actual requirements, and multiple purposes of the pipelines are achieved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a finned heat exchanger and a refrigeration device. Background technique [0002] Since the implementation of the energy efficiency rating system for commercial refrigeration products, the energy efficiency rating of commercial refrigerators has attracted much attention as an important indicator of product competitiveness. As a part of the refrigeration system, the heat exchanger's heat exchange efficiency affects the energy efficiency level of the product. Compared with ordinary refrigeration pipeline heat exchangers, the heat exchange efficiency of the finned heat exchangers used in the current products is already relatively high, but it still needs to be further improved. [0003] The heat transfer of the finned heat exchanger is related to factors such as the material of the refrigeration pipeline, the inner and outer areas of the tube, the surface area of ​​the fins, ...
