[0030] The preferred embodiments of the present application will be described in detail below with reference to the drawings, wherein the drawings constitute a part of this specification, and are used to explain the principles of the present application together with the embodiments of the present application, but are not intended to limit the scope of the present application.

[0031] Embodiment one

[0032] The embodiment provides an anti-impact liquid storage tank, referring to Figure 1 , comprising a tank body 1 and a distributing net 2, the shape of the distributing net 2 is conical, and the top point of the conical shape is upward, the top point of the conical shape is located directly below or inserted into the liquid inlet of the liquid storage tank, the edge of the distributing net 2 is in contact with the side wall of the tank body 1, the side wall of the tank body 1 is provided with a spiral flow guide groove, and the spiral flow guide groove extends to the bottom of the tank body 1.

[0033] Compared with the prior art, the anti-impact liquid storage tank provided in the embodiment has the following advantages: on the one hand, the distributing net 2 is arranged in the tank body 1, when the heat exchange medium flows into the tank body 1 from the liquid inlet, the heat exchange medium first contacts the top point of the distributing net 2, and then flows along the top point of the distributing net 2 to the edge of the distributing net 2, and then flows along the side wall of the tank body 1 to the bottom of the tank body 1, so that the impact of the heat exchange medium on the bottom of the tank body 1 can be reduced, and the service life of the tank body 1 can be effectively prolonged. On the other hand, the spiral flow guide groove is arranged on the side wall of the tank body 1, so that the heat exchange medium can form a rotational flow along the spiral flow guide groove, and the groove wall of the flow guide groove can further buffer the flow of the heat exchange medium, so that the impact of the heat exchange medium on the bottom of the tank body 1 can be further reduced, and the service life of the tank body 1 can be further prolonged.

[0034] In order to effectively avoid the heat exchange medium directly flowing out of the mesh holes of the liquid distribution net 2, the mesh holes are shaped as rhombuses, and the long sides of the rhombuses are arranged along the direction from the vertex to the edge of the liquid distribution net 2, so that the heat exchange medium flowing out of the vertex can flow along the acute angle in the mesh hole, the acute angle can better guide the heat exchange medium, and the heat exchange medium can smoothly flow to the edge of the liquid distribution net 2.

[0035] It is worth noting that in the prior art, the liquid adding funnel is directly in the external environment, and may be mixed with dissolved oxygen during the liquid adding process, causing corrosion of the heat exchanger and affecting the heat exchange performance of the heat exchanger. Therefore, the above-mentioned anti-impact liquid storage tank further comprises a liquid supply cavity 3 and a suction pump 4, the liquid outlet of the liquid supply cavity 3 is connected with the liquid inlet of the tank body 1, and the air inlet of the suction pump 4 is connected with the air outlet of the tank body 1.

[0036] In this way, when it is necessary to add the heat exchange medium to the liquid storage tank, the suction pump 4 is first opened, the suction pump 4 can perform vacuumization on the tank body 1 to generate negative pressure in the tank body 1, then the suction pump 4 is closed, and the connecting pipeline between the liquid supply cavity 3 and the tank body 1 is opened, under the action of the negative pressure, the liquid in the liquid supply cavity 3 can directly enter the tank body 1. Since the liquid supply tank is a relatively closed cavity, the mixing of dissolved oxygen during the flow of the heat exchange medium from the liquid supply tank to the tank body 1 can be reduced, and the vacuumization of the tank body 1 by the suction pump 4 can utilize negative pressure suction instead of a fluid pump to realize the flow of the heat exchange medium from the liquid supply tank to the tank body 1.

[0037] It can be understood that in order to realize the communication or disconnection control of the connecting pipeline between the tank body 1 and the suction pump 4, the above-mentioned anti-impact liquid storage tank further comprises a suction control valve 5, which is arranged on the connecting pipeline between the tank body 1 and the suction pump 4, and is used for controlling the communication or disconnection of the connecting pipeline between the tank body 1 and the suction pump 4.

[0038] Correspondingly, in order to realize the communication or disconnection control of the connecting pipeline between the tank body 1 and the liquid supply cavity 3, the above-mentioned anti-impact liquid storage tank further comprises a liquid supply control valve 6, which is arranged on the connecting pipeline between the tank body 1 and the liquid supply cavity 3, and is used for controlling the communication or disconnection of the connecting pipeline between the tank body 1 and the liquid supply cavity 3.

[0039] Considering that the negative pressure value in the tank body 1 determines the flow rate of the heat exchange medium supplied into the tank body 1, the above-mentioned anti-impact liquid storage tank further comprises a vacuum gauge 7, which is arranged on the connecting pipeline between the tank body 1 and the suction pump 4, and is used for detecting the negative pressure value in the tank body 1 in real time, so as to ensure that the tank body 1 has sufficient negative pressure suction force, so that the heat exchange medium can smoothly flow into the tank body 1 from the liquid supply cavity 3.

[0040] In order to improve the filling efficiency of the liquid storage tank, the number of the tank bodies 1 is multiple, the number of the suction pump 4 and the liquid supply cavity 3 is one, that is, one suction pump 4 and the liquid supply cavity 3 correspond to multiple tank bodies 1, which can simultaneously perform vacuumizing on multiple tank bodies 1, and can simultaneously perform heat exchange medium filling on multiple tank bodies 1.

[0041] From the perspective of structural simplification, the number of the tank bodies 1 is 2-4.

[0042] Correspondingly, the connecting pipeline of the tank body 1 and the suction pump 4 includes a suction main pipe 8 and multiple suction branch pipes 9, the suction branch pipe 9 corresponds to the tank body 1 one by one, and the suction pump 4 is connected with the tank body 1 through the suction main pipe 8 and the suction branch pipe 9 in sequence.

[0043] The connecting pipeline of the tank body 1 and the liquid supply cavity 3 includes a liquid supply main pipe 10 and multiple liquid supply branch pipes 11, the liquid supply branch pipe 11 corresponds to the tank body 1 one by one, and the liquid supply cavity 3 is connected with the tank body 1 through the liquid supply main pipe 10 and the liquid supply branch pipe 11 in sequence.

[0044] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
