Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchangers, and in particular relates to a high-efficiency heat exchanger for a refrigeration system. Background Art

[0002] A heat exchanger (also known as a heat exchanger or heat exchange equipment) is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction. In a refrigeration system, a heat exchanger is an indispensable component. In a traditional heat exchanger, the interior of the tank is filled with water, but this heat exchange process can only exchange heat on the heat exchange tubes in contact with the water. This method results in low heat exchange efficiency. At the same time, existing heat exchangers are affected by the structure and are either installed horizontally or vertically. The structure and cost of horizontally installed heat exchangers and vertically installed heat exchangers are different. Based on this, we propose a high-efficiency heat exchanger for use in a refrigeration system that can effectively improve the heat exchange efficiency and whose installation method is not affected by the structure. Utility Model Content

[0003] The purpose of the utility model is to provide a high-efficiency heat exchanger for a refrigeration system, aiming to solve the problems raised in the background technology.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-efficiency heat exchanger for a refrigeration system, comprising a shell, end covers installed at both ends of the shell, a mounting member installed in the shell, a spiral tube wound around the surface of the mounting member, an inlet pipe and an outlet pipe respectively provided at both ends of the spiral tube, the inlet pipe and the outlet pipe at both ends of the spiral tube respectively passing through the end covers at both ends of the shell and extending to the outside, and a water inlet and a water outlet respectively opened on the surfaces of the end covers at both ends of the shell;

[0005] The mounting piece is made of a mounting post, a spiral groove is provided on the surface of the mounting post, and the spiral tube is wound and mounted in the spiral groove.

[0006] As a preferred technical solution of the present invention, the inlet pipe is located on the side of the end cover having the water outlet, and the outlet pipe is located on the side of the end cover having the water inlet.

[0007] As a preferred technical solution of the present invention, the shell is a circular tubular structure in the middle of the interior, and the diameter of the mounting post matches the inner diameter of the shell.

[0008] As a preferred technical solution of the present invention, the end cover is fixedly connected to the shell by welding.

[0009] As a preferred technical solution of the present invention, the water inlet and the water outlet are respectively connected to the output end of the water pump and the input end of the refrigeration component, and the inlet pipe and the outlet pipe are respectively connected to the throttle valve and the input end of the compressor.

[0010] Compared with the prior art, the beneficial effects of the present invention are: since the inlet pipe is located on the side of the end cover with the water outlet, and the discharge pipe is located on the side of the end cover with the water inlet, the flow direction of the water along the spiral groove is opposite to the flow direction of the refrigerant along the spiral tube, and the diameter of the mounting column matches the inner diameter of the shell. In this way, the water entering the shell is forced to cross-exchange heat with the spiral tube, and the spiral groove is set so that the water can flow in the spiral groove at a faster flow rate, reducing the noise of the water flow, and the refrigerant can be fully vaporized in the spiral tube, thereby effectively improving the heat exchange efficiency. At the same time, the heat exchanger has a simple structure, is not only low in cost, but can also be installed horizontally or vertically, which can effectively reduce the user's cost investment.

[0021] Specifically, the spiral groove 9 is provided so that the spiral tube 4 can be wound and installed in the spiral groove 9, and the installation column 10 is installed in the shell 1. The refrigerant is introduced into the spiral tube 4, and water is introduced into the shell 1. The refrigerant can be fully vaporized through the spiral tube 4, and the flow rate of the refrigerant is fast, which can effectively improve the heat exchange efficiency.

[0023] Specifically, since the inlet pipe 5 is located on the side of the end cover 2 with the water outlet 8, and the discharge pipe 6 is located on the side of the end cover 2 with the water inlet 7, the flow direction of the refrigerant in the spiral tube 4 is opposite to the flow direction of the water along the spiral groove 9 in the shell 1, so that the water flow can cross the spiral tube 4 for forced heat exchange, and the water flow rate is fast and not restricted by direction, so the noise of the water flow can be effectively reduced.

[0026] It is worth mentioning that the heat exchanger is particularly suitable for micro refrigeration systems such as air-conditioning refrigeration clothing, beauty refrigeration units, and computer chip refrigeration and cooling, wherein the refrigeration parts include but are not limited to air-conditioning refrigeration clothing and beauty refrigeration units.

[0027] Working principle: Since the inlet pipe 5 is located on the side of the end cover 2 with the water outlet 8, and the discharge pipe 6 is located on the side of the end cover 2 with the water inlet 7, the flow direction of the water along the spiral groove 9 is opposite to the flow direction of the refrigerant along the spiral tube 4, and the diameter of the mounting column 10 matches the inner diameter of the shell 1. In this way, the water entering the shell 1 is forced to cross-exchange heat with the spiral tube 4, and the spiral groove 9 is set so that the water can flow in the spiral groove 9 at a faster flow rate, reducing the noise of the water flow, and the refrigerant can be fully vaporized in the spiral tube 4, thereby effectively improving the heat exchange efficiency. At the same time, the heat exchanger has a simple structure, is not only low in cost, but can also be installed horizontally or vertically, which can effectively reduce the user's cost investment.
