Description

Technical Field

[0001] This application relates to the technical field of radiators, and particularly to a radiator for adjusting the storage amount of phase change materials. Background Art

[0002] Radiators are commonly used heat dissipation devices, and phase change radiators are a type of radiator. The phase change radiator is filled with a phase change material inside. The phase change material evaporates when heated and condenses when cooled, and the heat dissipation of the heat dissipation device is achieved through the gas-liquid phase change process of the phase change material.

[0003] However, during the actual use of the phase change radiator, sometimes the phase change material evaporates when heated, but the condensation rate of the phase change material is insufficient, resulting in insufficient storage of the liquid phase, and thus the heat dissipation effect of the phase change radiator is poor. Utility Model Content

[0006] A radiator for adjusting the storage amount of phase change materials, comprising:

[0007] A liquid storage tank;

[0008] A cooling plate, with a cavity formed inside, and a phase change coolant is introduced into the cavity;

[0010] A cavity liquid level detection part, electrically connected to the adjusting pump;

[0011] Wherein, the liquid outlet end of the liquid duct is installed on the inner wall of the cavity near the heat source through a mounting part;

[0012] The height of the liquid level inside the cavity is detected by the cavity liquid level detection part. When the height of the liquid level inside the cavity is lower than the set value, the phase change coolant inside the liquid storage tank is pumped into the cavity through the adjusting pump for replenishment.

[0013] Optionally, the cavity liquid level detection part includes a detection tube and a liquid flow meter installed on the detection tube. The liquid inlet end of the detection tube is connected to the cavity, and the liquid outlet end of the detection tube is connected to the liquid storage tank.

[0014] Optionally, a cooling pipe is installed inside the liquid storage tank. The cooling pipe is arranged in a spiral shape, and the liquid inlet end of the cooling pipe is communicated with the gas outlet end of the air guide pipe.

[0015] Optionally, the mounting member includes a mounting plate installed on the inner wall of the cavity near the heat source. A diversion groove is formed on one side of the mounting plate close to the side wall of the cavity. The liquid outlet end of the liquid guide pipe is communicated with the diversion groove.

When the liquid level in the cavity is higher than the set value, the phase change coolant inside the cavity flows into the liquid storage tank inside at a relatively slow speed, and the flow rate of the phase change coolant inside the detection pipe is detected by the liquid flow meter. Then, when the flow rate of the phase change coolant is zero, the liquid flow meter will send a signal to the regulating pump, so that the regulating pump pumps a certain amount of the phase change coolant inside the liquid storage tank into the cavity. When the phase change coolant enters the diversion groove, the overall fan-shaped distributed diversion protrusions increase the contact area and contact time between the phase change coolant and the inside of the cavity. At the same time, the blocking protrusions guide the phase change coolant, and further improve the possibility of the phase change coolant contacting the inner wall of the cavity. After the phase change coolant is heated and evaporated and enters the cooling pipe from the air guide pipe, the spiral-shaped cooling pipe prolongs the heat exchange time of the phase change coolant and improves the heat exchange effect of the phase change coolant.

[0028] The following further elaborates on the present application in conjunction with the attached Figures 1 - 3 drawings for a more detailed description.

[0029] The embodiment of the present application discloses a radiator for adjusting the storage amount of phase change material.

[0030] A radiator for adjusting the storage amount of phase change material includes a liquid storage tank 1, a cooling plate 2, an adjusting part 3, and a cavity liquid level detection member 4. A cavity is formed inside the cooling plate 2, and a phase change coolant is introduced into the cavity. The liquid storage tank 1 is located near the cooling plate 2. The cavity liquid level detection member 4 detects the liquid level inside the cavity. When the liquid level inside the cooling plate 2 is lower than the set value, the phase change coolant inside the liquid storage tank 1 is timely transported into the cavity inside the cooling plate 2 through the adjusting part 3 for replenishment.

[0031] The adjusting part 3 includes an air guide pipe 31, a liquid guide pipe 32, and an adjusting pump 33. The air inlet end of the air guide pipe 31 is communicated with the top of the cavity, and the air outlet end of the air guide pipe 31 is communicated with the liquid storage tank 1. A fan 34 is installed on the air guide pipe 31 to facilitate transporting the gaseous phase change coolant into the liquid storage tank 1. The liquid inlet end of the liquid guide pipe 32 is communicated with the liquid storage tank 1, and the liquid outlet end of the liquid guide pipe 32 is communicated with the cavity. The adjusting pump 33 is installed at the middle position of the liquid guide pipe 32.

[0032] A cooling pipe is installed inside the liquid storage tank 1. The cooling pipe is arranged in a spiral shape, and the liquid inlet end of the cooling pipe is communicated with the air outlet end of the air guide pipe 31. When the phase change coolant enters the cooling pipe from the air guide pipe 31, the spiral-shaped cooling pipe prolongs the heat exchange time of the phase change coolant and improves the heat exchange effect of the phase change coolant.

[0033] The cavity liquid level detector 4 includes a detection tube 41 and a liquid flowmeter 42 installed on the detection tube 41. The liquid flowmeter 42 is electrically connected to the regulating pump 33. The liquid inlet end of the detection tube 41 is communicated with the cavity, and the liquid outlet end of the detection tube 41 is communicated with the liquid storage tank 1. When the liquid level in the cavity is higher than the set value, the phase change coolant inside the cavity flows into the inside of the liquid storage tank 1 at a relatively slow speed, and the liquid flowmeter 42 detects the flow rate of the phase change coolant inside the detection tube 41. Then, when the flow rate of the phase change coolant is zero, the liquid flowmeter 42 will send a signal to the regulating pump 33 to pump a certain amount of the phase change coolant inside the liquid storage tank 1 into the cavity.

[0034] The liquid outlet end of the liquid guide tube 32 is installed on one side of the inner wall of the cavity close to the heat source through the mounting member 35. The mounting member 35 includes a mounting plate 351 installed on one side of the inner wall of the cavity close to the heat source.

[0035] The mounting member 35 includes a mounting plate 351 installed on one side of the inner wall of the cavity close to the heat source. A plurality of flow guiding protrusions 353 are installed on one side of the mounting plate 351 close to the cavity side wall. A flow guiding groove is formed between two adjacent flow guiding protrusions 353. The liquid outlet end of the liquid guide tube 32 is communicated with the flow guiding groove. Each flow guiding protrusion 353 is distributed in a serpentine shape.

[0036] The phase change coolant pumped from the inside of the liquid storage tank 1 into the cavity flows inside the guiding groove. Since a plurality of flow guiding protrusions 353 are distributed in a fan shape and each flow guiding protrusion 353 is distributed in a serpentine shape, during the movement of the phase change coolant inside the flow guiding groove, the contact area and contact time between the phase change coolant and the inside of the cavity are increased. Thus, it is convenient to quickly dissipate heat from the cavity side wall and improve the heat dissipation effect on the heat source.

[0037] A plurality of blocking protrusions 354 are arranged on the inner wall of the flow guiding groove along the length direction of the flow guiding groove, and the blocking protrusions 354 are arranged in a spherical shape. When the phase change coolant moves inside the flow guiding groove, the blocking strip blocks the phase change coolant, causing the phase change coolant to move towards the direction close to the heat source. Furthermore, the possibility of contact between the phase change coolant and the inner wall of the cavity is further improved.

[0038] The mounting member 35 further includes a mounting piece 352 installed on the side of the mounting plate 351. A screw penetrates through the mounting piece 352, and the screw is threadedly connected to the inner wall of the cavity.

[0039] The implementation principle of a radiator for adjusting the storage capacity of a phase change material in an embodiment of this application is as follows: when the liquid level in the cavity is higher than the set value, the phase change coolant inside the cavity flows into the inside of the liquid storage tank 1 at a relatively slow speed, and the flow rate of the phase change coolant inside the detection tube 41 is detected by the liquid flowmeter 42. Then, when the flow rate of the phase change coolant is zero, the liquid flowmeter 42 will send a signal to the regulating pump 33, causing the regulating pump 33 to pump a certain amount of the phase change coolant inside the liquid storage tank 1 into the cavity. When the phase change coolant enters the diversion groove, the diversion protrusions 353 distributed in a fan shape increase the contact area and contact time between the phase change coolant and the inside of the cavity. At the same time, the blocking protrusions 354 guide the phase change coolant, thereby further increasing the possibility of the phase change coolant coming into contact with the inner wall of the cavity. After the phase change coolant evaporates due to heat and enters the cooling tube from the gas guide tube 31, the cooling tube arranged in a spiral shape extends the heat exchange time of the phase change coolant and improves the heat exchange effect of the phase change coolant.

[0040] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, any equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
