Detailed Description
The invention provides a circulating cooling system, which fundamentally solves the problems of cavitation, pipe expansion and abnormal sound by improving the structure of the circulating cooling system, so that the service life of the circulating cooling system is longer and the working effect is better.
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, an embodiment of the present invention provides a circulation cooling system for being mounted on an electronic device to dissipate heat of the electronic device, including: the heat absorption component 1 is used for absorbing heat emitted by the electronic equipment, the heat exchange component 2 is used for exchanging heat with a cooling medium outside the electronic equipment, the heat absorption component 1 is circularly communicated with the heat exchange component 2, the liquid guide pipeline 3 is internally provided with cooling liquid, the liquid guide pipeline 3 is also provided with a pump 4 and a ventilation valve 5, the pump 4 supplies power for the flow of the cooling liquid in the liquid guide pipeline 3, the ventilation valve 5 is also arranged on the liquid guide pipeline 3, and the gas in the cooling liquid can overflow from the liquid guide pipeline 3, but the cooling liquid cannot leak through the ventilation valve 5.
According to the circulating cooling system provided by the embodiment, the ventilation valve 5 is additionally arranged in the circulating cooling system, so that gas in the cooling liquid can be thoroughly discharged out of the circulating cooling system, the circulating cooling system is free from gas, meanwhile, the cooling liquid is free from leakage, and the problems of cavitation, pipe expansion and abnormal sound of the circulating cooling system are fundamentally avoided on the premise that the cooling effect is not affected.
In order to further optimize the technical solution, in the circulation cooling system provided in this embodiment, it is preferable that the inlet of the pump 4 is communicated with the heat absorbing component 1, the outlet of the pump 4 is communicated with the heat exchanging component 2, and the ventilation valve 5 is disposed between the pump 4 and the heat exchanging component 2 and is disposed near the outlet of the pump 4, that is, the ventilation valve 5 is preferably disposed at the outlet of the pump 4, as shown in fig. 1. Since the inlet of the pump 4 is communicated with the heat absorbing component 1 and the outlet of the pump 4 is communicated with the heat exchanging component 2, the working mode of the cooling liquid is as follows: the heat absorbing component 1 absorbs heat, the cooling liquid with higher temperature flows to the pump 4, enters the pump 4 through the inlet, flows out of the outlet of the pump 4 through the pressurization of the pump 4, then enters the heat exchanging component 2 for heat exchange, and the cooling liquid with lower temperature flows out of the heat exchanging component 2 after heat exchange and flows to the heat absorbing component 1 again to absorb heat, as shown by an arrow in fig. 1. In this flowing process, because the turbulence of the pump 4 causes the cooling liquid to flow out from the outlet of the pump 4, the amount of the gas existing in the cooling liquid reaches the highest value, so compared with other parts, the ventilation valve 5 is arranged at the outlet of the pump 4, so that the gas in the cooling liquid can be discharged to the greatest extent, a more efficient exhaust effect is achieved, and the probability of cavitation, pipe expansion and abnormal sound of the circulating cooling system is minimized.
In addition to the above arrangement, the ventilation valve 5 may be disposed between the pump 4 and the heat absorbing member 1, that is, the ventilation valve 5 may be disposed at an inlet portion of the pump 4, or the ventilation valve 5 may be disposed between the heat exchanging member 2 and the heat absorbing member 1, so that the purpose of exhausting the gas in the cooling liquid may be achieved.
Specifically, the material of the ventilation valve 5 may be selected from various materials such as plastics and metals on the premise of removing the liquid in the coolant and ensuring that the cooling effect is not reduced, but in view of the service life and other factors, the ventilation valve 5 is preferably a metal ventilation valve 5.
In the present embodiment, the heat exchange member 2 preferably includes: a heat exchange tube in which a coolant flows; and the heat exchange plates are connected with the heat exchange tubes, and the surface area of the heat exchange plates is larger than that of the heat exchange tubes. The heat exchange component 2 not only comprises a heat exchange tube for guiding cooling liquid, but also comprises a heat exchange sheet which is in contact with the heat exchange tube and can perform heat transfer, so that the heat exchange tube and the heat exchange sheet can perform heat exchange with external air at the same time, the surface area of the heat exchange component 2 is further increased, the heat exchange component 2 can perform heat exchange with the external air of the electronic equipment more efficiently, and the heat dissipation effect and the heat dissipation efficiency of the circulating cooling system are further improved.
Specifically, the heat sink 1 is preferably a heat conductive sheet that can be directly bonded to the cpu of the electronic device. The structure of the heat absorbing component 1 and the matching mode with the heat dissipating component in the electronic device can have various choices, and since the central processing unit is the main heat dissipating component in the electronic device, the heat absorbing component 1 is preferably arranged around the central processing unit, so that the heat emitted by the electronic device can be more fully absorbed, and the heat absorbing component 1 is more preferably attached to the central processing unit, so that the heat can be directly and fully transferred into the heat absorbing component 1, and the cooling effect can be optimized. In the present embodiment, the heat sink 1 is preferably a heat conductive sheet because the sheet structure is small in size, easy to install, more suitable for the installation environment of the electronic device, and also more suitable for the structure of the cpu, so that it is a preferable structure.
Based on the circulation cooling system provided in the above embodiment, the embodiment of the invention also provides an electronic device having the circulation cooling system provided in the above embodiment.

In particular, in this embodiment, the electronic device is preferably a desktop computer.
In the present description, the structures of the parts are described in a progressive manner, and the structure of each part is mainly described as a difference from the existing structure, and the whole and part structures of the electronic device and the circulation cooling system can be obtained by combining the structures of the parts.
