Description

Technical Field

[0001] The utility model relates to the technical field of liquid coolers, in particular to a dual-cooling-source liquid cooler. Background Art

[0002] With the development of society, environmental pollution and energy crisis have become the top priorities threatening human survival. How to solve this problem has become a topic of great concern to all mankind. Against this background, green buildings and corresponding air-conditioning systems featuring environmental protection and energy conservation have emerged as the times require.

[0003] A heat pipe is a heat transfer element with high thermal conductivity. It transfers heat through the evaporation and condensation of the working fluid in a fully enclosed vacuum tube shell. Since it is a phase change heat transfer, the internal thermal resistance of the heat pipe is very small, and it has a series of advantages such as extremely high thermal conductivity, good isothermal property, and rapid startup. The heat exchange between the hot and cold fluids is carried out outside the tube, and it is convenient to enhance heat transfer. Therefore, developing a heat pipe type air-conditioning unit with high energy efficiency and reliable operation using the principle of heat pipes is the development trend of future computer room air conditioners.

[0004] In view of this, the heat pipe air-conditioning system is a technological innovation direction with broad technical prospects, and relevant technological innovation achievements have also emerged in China. For example, the patent technology with the publication number CN221098862U owned by the applicant proposed a technological innovation of a heat pipe dual-cooling-source air-conditioning system, which saved energy consumption. However, its heat exchanger is installed on the side, and during actual operation, it will generate relatively large noise.

[0005] Therefore, a dual-cooling-source liquid cooler is now proposed to solve the above problems. Summary of the Invention

[0007] The purpose of the utility model is achieved by adopting the following technical solutions:

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The first condenser 51 is installed at the top inside the housing 1, and the second condenser 52 and the water storage tank 53 are respectively installed above the opposite two side parts inside the housing 1; wherein, the first condenser 51 and the second condenser 52 are arranged in parallel;

[0040] The plate evaporator 6 is provided with a heat pipe inlet 61 and a heat pipe outlet 62 that are internally connected, an air-conditioning inlet 63 and an air-conditioning outlet 64 that are internally connected, and a water pump inlet 65 and a water pump outlet 66 that are internally connected;

[0041] The air-conditioning system includes a compressor 21. The compressor 21 is respectively connected to the first condenser 51 and the second condenser 52 through a high-pressure pipe 22. The first condenser 51 and the second condenser 52 are respectively connected to the air-conditioning inlet 63 of the plate evaporator 6 through a throttle valve 22. The air-conditioning outlet 64 of the plate evaporator 6 is connected to the compressor 21 through a low-pressure pipe 23;

[0042] The heat pipe system includes an inlet heat pipe 31 and an outlet heat pipe 32; the inlet heat pipe 31 is connected to the heat pipe inlet 61 of the plate evaporator 6, the heat pipe outlet 62 of the plate evaporator 6 is connected to the outlet heat pipe 32, and the outlet heat pipe 32 is connected to the second condenser 52;

[0043] The water pump system includes a water pump 41, a water inlet pipe 42, and a drain pipe 43; one end of the water inlet pipe 42 is connected to the water inlet of the water pump 41 and the water storage tank 53 through a three-way valve, and the other end of the water inlet pipe 42 is connected to a water supply source (not shown) outside the housing 1; the drain outlet of the water pump 41 is connected to the water pump inlet 65 of the plate evaporator 6, the water pump outlet 66 of the plate evaporator 6 is connected to the drain pipe 43, and the drain pipe 43 leads to the outside of the housing 1.

[0044] In this application, the first condenser and the second condenser are arranged at the top and side of the housing, and the first condenser and the second condenser are arranged in parallel. Without reducing the overall heat dissipation effect, the power of each condenser is reduced, thereby achieving the effect of noise reduction.

[0045] As a preferred solution, an electric ball valve is installed on the inlet heat pipe 31.

[0046] As a preferred solution, a fan 8 is arranged in the housing 1.

[0047] As a preferred solution, a liquid receiver dryer 24 is arranged between the condensation system 5 and the throttle valve 25. One end of the liquid receiver dryer 24 is connected to the throttle valve 25, and the other end of the liquid receiver dryer 24 is respectively connected to the first condenser 51 and the second condenser 52.

[0048] As a preferred solution, in the plate evaporator 6, the heat pipe inlet 61 and the heat pipe outlet 62 are diagonally distributed, and the air conditioner inlet 63 and the air conditioner outlet 64 are diagonally distributed.

[0049] As a preferred solution, filter nets 11 are installed above the top and side of the housing 1. The first condenser 51 is arranged between the filter net 11 at the top of the housing 1 and the water storage tank 53, and the second condenser 52 is arranged between the filter net 11 above the side of the housing 1 and the water storage tank 53.

[0050] In this embodiment, the specific situation during the operation of the air-conditioning system is as follows:

[0051] When the refrigeration function needs to be realized, the compressor produces high-temperature and high-pressure steam. The high-temperature and high-pressure steam enters the condenser for condensation to obtain high-pressure liquid. The high-pressure liquid comes out of the condenser and passes through the throttle valve to obtain low-temperature and low-pressure wet steam. The low-temperature and low-pressure wet steam enters the plate evaporator from the air conditioner inlet. At this time, the low-temperature and low-pressure wet steam in the plate evaporator will emit cold gas, and then the fan blows these cold gases outwards to achieve the refrigeration effect. After that, the steam inside the plate evaporator will get hot to obtain low-pressure steam, and the low-pressure steam enters the compressor again, thereby realizing the cycle.

[0052] When the dual-cooling-source liquid cooler according to the embodiment of the present utility model is in operation, it includes the following steps:

[0053] A. Operate the heat pipe system. The heat pipe system provides heat to the plate evaporator and thaws and preheats the liquid inside the plate evaporator;

[0054] B. Observe whether the heat provided by the heat pipe can meet the heat dissipation requirements;

[0055] When the heat provided by the heat pipe cannot meet the heat dissipation requirements, the compressor needs to be started to operate the air conditioning system to achieve refrigeration;

[0056] When the heat provided by the heat pipe can meet the heat dissipation requirements, there is no need to start the compressor to achieve the refrigeration effect.

[0057] Specifically, when the refrigeration function needs to be achieved in a low-temperature environment, confirm that the electric ball valve is in the open state, and operate the heat pipe system. The heat pipe system provides heat to the plate evaporator and thaws and preheats the liquid inside the plate evaporator (the liquid in the pipeline is in a frozen state in a low-temperature environment). At this time, according to the different ambient air temperatures, it can be divided into the following two situations:

[0058] Situation 1: If the heat provided by the heat pipe can meet the heat dissipation requirements, there is no need to start the compressor, and the liquid inside the plate evaporator can be vaporized, so that the environment outside the plate evaporator drops, and then the cold air outside the plate evaporator is blown out by the fan to achieve the refrigeration effect;

[0059] Situation 2: If the heat provided by the heat pipe is not enough to meet the heat dissipation requirements, the compressor needs to be started to operate the air conditioning system to achieve refrigeration; at this time, since the heat pipe system has preheated the liquid inside the plate evaporator, the liquid circulates between the plate evaporator, the condenser and the compressor, which can play a good lubricating effect on the pipeline and facilitate the realization of the refrigeration function.

[0060] The above embodiments only express several implementation manners of the present utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can be made. These are all equivalent modifications and evolutions made to the above embodiments based on the essential technology of the present utility model, and these all belong to the protection scope of the present utility model.
