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, including a fin group and a plurality of heat exchange tubes, each fin is provided with a first through hole and a second through hole, and each heat exchange tube Integral bending and molding, several heat exchange tubes pass through the first through hole and the second through hole from the left or right side of the fin, and several conversely pass through the second through hole from the right side or left side of the fin. The sum of the heat exchange tubes that need to pass through the first through hole and the second through hole at the same time has one more plane layer than the sum of the heat exchange tubes that only need to pass through the second through hole. Standalone or communicated through connectors. By adding holes on the basis of the original fins, multiple heat exchange tubes pass through the opposite sides of the fins to form a cross or staggered pipeline arrangement, which improves the pipeline arrangement rate in a limited space and effectively solves the problem. It solves the problem of how to increase the heat exchange area of ​​the finned heat exchanger in a limited space; and the connection mode of the inlet and outlet of each heat exchange tube can be flexibly selected according to actual needs to realize the multi-purpose of the pipeline.

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, ...
