Description

Technical Field

[0001] This utility model relates to the field of heat dissipation and heat exchange equipment technology, and more specifically to a liquid cooling heat exchange system. Background Technology

[0002] In some existing large control equipment, the internal circuit boards and other electronic components generate a lot of heat during operation. In order to ensure normal operation and rapid cooling, the existing method is to install a circulating fan on the housing of the control equipment for cooling. However, its heat dissipation effect is limited, especially in summer when the heat dissipation effect is even worse. Therefore, existing liquid cooling methods involve attaching a heat exchange plate or heat exchange tube with internal cooling liquid flow to one side of components such as circuit boards to achieve rapid cooling. This is achieved by the low-temperature liquid flowing through the heat exchange plate or tube, exchanging heat with the circuit board outside the plate or tube, thus ensuring normal equipment operation. However, the liquid after heat exchange needs to flow to external refrigeration equipment for further cooling. Existing refrigeration equipment typically has a water tank where the evaporator is submerged. Returning water enters the tank, exchanges heat with the evaporator, and is then pumped out to flow back into the heat exchange plate or tube. However, the tank contains a large amount of water, while the amount flowing through the heat exchange plate or tube is relatively small, resulting in waste, significantly reduced energy utilization, and high energy loss. Moreover, its inclusion of structures such as a pool greatly increases its size and occupies too much space, resulting in an unsatisfactory effect. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a liquid cooling heat exchange system that is small in size and occupies little space. Moreover, the heat exchange liquid flows directly in the inner tube and exchanges heat directly with the refrigerant flowing between the inner tube and the heat exchange tube, which greatly improves the heat exchange efficiency. It can achieve heat exchange without too much heat exchange liquid, has a high heat exchange utilization rate, and greatly reduces energy consumption and energy loss.

[0004] The solution of this utility model to the aforementioned technical problem is: A liquid cooling heat exchange system includes a fixed base plate, a compressor assembly fixed in the middle of the top surface of the fixed base plate, a spirally wound condenser placed on the top surface of the fixed base plate, a spirally wound evaporator above the condenser, and the compressor assembly inserted into a through hole in the middle of the condenser and the evaporator. Both the condenser and the evaporator are spirally wound heat exchange tubes, with an inner tube inserted inside. The inner tube is spirally wound along with the heat exchange tube. The connecting pipes formed at both ends of the inner tube extend out of both ends of the heat exchange tube. The inner sidewalls of both ends of the heat exchange tube are welded and fixed to the outer sidewalls of the corresponding ends of the inner tube. Refrigerant connection pipe joints are welded and fixed to the outer walls of the heat exchange tubes near both ends. One end of the refrigerant connection pipe joint is connected to the corresponding heat exchange tube. The outlet of the compressor assembly is connected to one end of the first connection pipe. The other end of the first connection pipe is connected to one end of the refrigerant connection pipe joint at one end of the condenser. One end of the refrigerant connection pipe joint at the other end of the condenser is connected to one end of the capillary tube. The other end of the capillary tube is connected to one end of the refrigerant connection pipe joint at one end of the evaporator. One end of the refrigerant connection pipe joint at the other end of the evaporator is connected to one end of the second connection pipe. The other end of the second connection pipe is connected to the inlet of the compressor assembly.

[0005] The outer wall of the heat exchange tube of the evaporator is covered with a heat insulation layer.

[0006] The outstanding effect of this utility model is: Compared with existing technologies, its compressor components are located in the condenser and evaporator, which greatly reduces its overall size. It is small in size and occupies little space. Moreover, its heat exchange liquid flows directly in the inner tube body, and it directly exchanges heat with the refrigerant flowing between the inner tube body and the heat exchange tube body, which greatly improves the heat exchange efficiency. It can achieve heat exchange without too much heat exchange liquid, and its heat exchange utilization rate is high, which greatly reduces energy consumption and energy loss.

Detailed Implementation

[0008] For example, see below. Figures 1 to 5As shown, a liquid cooling heat exchange system includes a fixed base plate 10, a compressor assembly 20 fixed in the middle of the top surface of the fixed base plate 10, a spirally wound condenser 30 placed on the top surface of the fixed base plate 10, and a spirally wound evaporator 40 provided above the condenser 30. The compressor assembly 20 is inserted into the middle through hole of the condenser 30 and the evaporator 40. The condenser 30 and the evaporator 40 are both spirally wound heat exchange tubes 1, with an inner tube 2 inserted inside. The inner tube 2 is spirally wound along with the heat exchange tube 1. The connecting pipes 3 formed at both ends of the inner tube 2 extend out of both ends of the heat exchange tube 1. The inner sidewalls of both ends of the heat exchange tube 1 are welded and fixed to the outer sidewalls of the corresponding ends of the inner tube 2. Refrigerant connection pipe joints 4 are welded and fixed on the outer walls near both ends of the heat exchange tube body 1. One end of the refrigerant connection pipe joint 4 is connected to the corresponding heat exchange tube body 1. The outlet of the compressor assembly 20 is connected to one end of the first connecting pipe 5. The other end of the first connecting pipe 5 is connected to one end of the refrigerant connection pipe joint 4 at one end of the condenser 30. One end of the refrigerant connection pipe joint 4 at the other end of the condenser 30 is connected to one end of the capillary tube 6. The other end of the capillary tube 6 is connected to one end of the refrigerant connection pipe joint 4 at one end of the evaporator 40. One end of the refrigerant connection pipe joint 4 at the other end of the evaporator 40 is connected to one end of the second connecting pipe 7. The other end of the second connecting pipe 7 is connected to the inlet of the compressor assembly 20.

[0009] Furthermore, the outer wall of the heat exchange tube 1 of the evaporator 40 is covered with a heat insulation layer 8. The heat insulation layer 8 can be made of rubber insulation material or sponge insulation material, etc. In this embodiment, nitrile rubber is used.

[0010] Furthermore, a horizontal plate extending to the left and right is fixed in the middle of the top surface of the fixed base plate 10. The horizontal plate is inserted into the gap between the top plate of the base of the compressor assembly 20 and the fixed base plate 10. The bottom of the base of the compressor assembly 20 has four connecting blocks, which are fixed to the top surface of the fixed base plate 10, so that a gap is formed between the bottom surface of the top plate of the base of the compressor assembly 20 and the top surface of the fixed base plate 10.

[0011] The horizontal plate has upwardly bent vertical bends 11 formed at both ends, and the condenser 30 is located between the two vertical bends 11.

[0012] The inner wall of the side vertical bend 11 is in close contact with or near the left or right side wall of the condenser 30.

[0013] Furthermore, the heat insulation layer 8 on the bottom surface of the evaporator 40 presses against the top surface of the condenser 30.

[0014] Furthermore, the heat exchange tube 1 has through holes formed on the side walls near both ends. The through holes communicate with the heat exchange tube 1 and are welded to one end of the heat exchange tube 1 with the corresponding refrigerant connection pipe joint 4.

[0015] The capillary tube 6 is located in the middle of the front of the condenser 30.

[0016] In this embodiment, the connecting pipes 3 formed at both ends of the inner tube 2 of the evaporator 40 can be connected to one end of two connecting pipes. One end of the other end of the two connecting pipes is connected to the heat exchange plate or heat exchange tube of the equipment to be cooled, and the other end of the connecting pipe is connected to the inlet of the delivery pump. The outlet of the delivery pump is connected to the other end of the heat exchange plate or heat exchange tube. By running the delivery pump, the heat exchange liquid in the inner tube 2 of the evaporator 40 can be flowed (the heat exchange liquid in this embodiment can be water). The cavity of the delivery pump can be connected to a liquid replenishment port at each point, and a plug is screwed on it. The plug can be opened to replenish the heat exchange liquid to ensure the normal flow of the heat exchange liquid.

[0017] During operation, the compressor assembly 20 compresses the refrigerant into a high-temperature, high-pressure gas, which enters the heat exchange tube 1 of the condenser 30. The two connecting pipes 3 of the inner tube 2 of the condenser 30 can be connected to the external cold water outlet and water outlet pipe, allowing cold water to circulate within the inner tube 2 of the condenser 30. This cold water exchanges heat with the refrigerant in the heat exchange tube 1 of the condenser 30, thereby raising the temperature of the water in the inner tube 2 of the condenser 30. Finally, the water is discharged from the corresponding water outlet pipe to the connected equipment for use. Of course, when not in use, plugs can be installed at the two connecting pipes 3 of the inner tube 2 of the condenser 30. When not in use, the outside of the condenser 30 can be cooled by an external blower, at which point the refrigerant becomes a high-pressure, room-temperature refrigerant liquid.

[0018] Then, the refrigerant enters the capillary tube 6 and becomes a low-temperature, low-pressure refrigerant. It then enters the heat exchange tube 1 of the evaporator 40, where it exchanges heat with the liquid water flowing in the inner tube 2 of the evaporator 40 (the temperature of which is about 30°C). This causes the temperature of the liquid water flowing in the inner tube 2 to drop to about 5°C. At the same time, the refrigerant flowing out of the heat exchange tube 1 of the evaporator 40 absorbs heat and vaporizes. Finally, it enters the compressor assembly 20 to achieve refrigerant circulation. The heat exchange liquid (liquid water) flowing out of the inner tube 2 of the evaporator 40 is a low-temperature liquid. It can enter the heat exchange plate or heat exchange tube of the equipment that needs to be cooled to exchange heat with the components of the equipment that need to be cooled, thereby reducing the temperature of the corresponding components and ensuring their normal operation.

[0019] Finally, the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model, and the patent protection scope of the present utility model should be defined by the claims.
