Referring to fig. 1 and 2, the radiator module includes a cooling module, a driving pump 5, and a pressure relief module 4.

Specifically, the cooling assembly comprises a heat exchange box 2 and a cooling pipe 3, wherein the heat exchange box 2 is provided with a cavity 21 filled with a cooling medium, and a first port 22 and a second port 23 communicated with the cavity 21 are arranged on the heat exchange box 2. One end of the cooling pipe 3 is communicated with the first port 22 of the heat exchange box 2, and the other end of the cooling pipe 3 is communicated with the second port 23 of the heat exchange box 2.

The driving pump 5 is disposed between the first port 22 and the second port 23, and the driving pump 5 is used for driving the cooling medium in the cavity 21 into the cooling pipe 3 and circularly flowing in a cooling circuit formed by the cooling pipe 3 and the heat exchange box 2.

The pressure relief assembly 4 specifically includes a pressure relief body having a pressure relief cavity therein, a movable plate 41 and an elastic member 44, the movable plate 41 dividing the pressure relief cavity into a first cavity section 46 and a second cavity section 47. Wherein the first cavity section 46 is communicated with the cavity 21 of the heat exchange box 2, and the second cavity section 47 is sealed with gas; the elastic member 44 is disposed in the second cavity section 47, and one end of the elastic member 44 is connected to the movable plate 41, and the other end of the elastic member 44 is connected to the inner wall of the second cavity section 47 remote from the first cavity section 46; the movable plate 41 is adapted to compress the gas in the second chamber section 47 when compressed.

On the basis of the structure, when the radiator module is used, the two ends of the cooling pipe 3 can be respectively welded with the first port 22 and the second port 23 on the heat exchange box 2 during assembly, so that a cooling circuit is formed between the cooling pipe 3 and the heat exchange box 2. The driving pump 5 is arranged between the first port 22 and the second port 23 and drives the cooling medium to flow in the cooling circuit. The pressure relief assembly 4 is mounted to the heat exchange box 2 and communicates with the cavity 21 through a communication port 42.

When the heat exchange box 2 is connected with a heating part of an electronic component, heat in the use process of the electronic component is continuously transferred to the heat exchange box 2 body, so that the temperature in the cavity 21 is increased; since the cavity 21 is filled with the cooling medium with large specific heat capacity, the cooling medium can effectively absorb the thermal shock of the heat exchange box 2 and realize heat dissipation after flowing in the cooling circuit.

Specifically, the cooling medium with higher temperature in the cavity 21 is led out into the cooling tube 3 through the first port 22 under the action of the driving pump 5, flows from one end of the cooling tube 3 to the other end of the cooling tube 3, and achieves heat dissipation when flowing in the cooling tube 3, and the cooling medium with reduced temperature is led into the cavity 21 of the heat exchange box 2 through the second port 23, so that a circulating flow process is completed. The cooling medium radiates heat into the air during the flow in the cooling pipe 3, thereby achieving the heat radiation effect of the radiator.

In this process, since the heat exchange tank 2 and the cooling pipe 3 are assembled to form a closed heat dissipation system, when the temperature in the cavity 21 of the heat exchange tank 2 is high, the cooling medium expands, resulting in an increase in the pressure in the cavity 21.

Because the pressure relief assembly 4 is communicated with the heat exchange box 2, and the first cavity section 46 in the pressure relief assembly 4 is communicated with the cavity 21 of the heat exchange box 2 through the communication port 42; therefore, when the cooling medium in the heat exchange box 2 expands due to heat, the cooling medium in the cavity 21 can flow into the first cavity section 46, so that pressure is generated on the movable plate 41 of the pressure relief assembly 4; when the movable plate 41 is pressed, the movable plate can move towards the second cavity section 47 and away from the inner wall of the first cavity section 46, and air in the second cavity section 47 is compressed, so that the space volume of the first cavity section 46 can be increased, the first cavity section 46 generates extra space to absorb the expansion liquid, and the pressure in the first cavity section 46 and the cavity 21 is reduced, so that the pressure in the heat dissipation system is balanced.

In addition, the both ends of cooling tube 3 respectively with heat exchange box 2's first port 22 and second port 23 carry out the welding and realize fixed connection to can guarantee the leakproofness of junction, prevent the weeping.

Further, referring to fig. 4, the pressure relief main body is provided with a communication port 42, and the communication port 42 is communicated with the first cavity section 46; referring to fig. 5, the communication port 42 is mounted to the heat exchange case 2 so that the first chamber section 46 communicates with the chamber 21.

Since the first chamber section 46 communicates with the chamber 21 through the communication port 42, the pressure in the first chamber section 46 and the chamber 21 is kept uniform; while the second chamber section 47 is insulated from the first chamber section 46 by the movable plate 41. After the elastic member 44 is installed in the second chamber section 47, the elastic member 44 assumes a stretched state due to the movable plate 41 having a certain weight. When the inside of the heat exchange box 2 is at normal temperature, the movable plate 41 is pulled by the elastic member 44 due to its own weight, so that the movable plate 41 can be prevented from blocking the communication port 42, and the space for accommodating the expansion cooling medium is ensured in the first chamber section 46.

When the temperature in the heat exchange box 2 increases, the cooling medium expands and enters the first chamber section 46 communicated with the chamber 21, and the hydraulic pressure and the air pressure of the first chamber section 46 are increased, so that the pressure is generated on the movable plate 41. Since the movable plate 41 is connected to the inner wall of the second chamber section 47, which is distant from the first chamber section 46, by the elastic member 44, the pressure of the first chamber section 46 can push the movable plate 41 to move and compress the gas of the second chamber section 47. At the same time, the volume of the space of the first chamber section 46 is correspondingly increased, and the first chamber section 46 is provided with additional space for absorbing the expansion liquid, so that the pressure of the first chamber section 46 and the communicated chamber 21 is balanced.

Wherein the elastic member 44 may be a spring or a telescopic balloon, the movable plate 41 compresses the gas in the second chamber section 47 by further compressing the spring or the balloon, so that the first chamber section 46 obtains an additional volume of space to absorb the pressure.

In addition, the pressure relief assembly 4 further includes a sealing member 410, where the sealing member 410 is disposed around the circumference of the movable plate 41 and is installed between the outer circumferential surface of the movable plate 41 and the inner wall of the pressure relief body, and the sealing member 410 fully fills the gap between the movable plate 41 and the inner wall of the pressure relief body, so that the first cavity section 46 and the second cavity section 47 are isolated from each other, and different pressure environments are formed.

Referring to fig. 6, in some embodiments, a pressure relief opening 48 is further provided on the pressure relief main body, and the pressure relief opening 48 is in communication with the second cavity section 47; the pressure relief vent 48 is used to relieve pressure when the second chamber section 47 is compressed.

It should be noted that, the pressure relief opening 48 is disposed on the end wall of the second cavity section 47 away from the first cavity section 46, and when the pressure relief opening 48 is closed, the movable plate 41 is away from the pressure relief opening 48 and is in a balanced state.

When the cooling medium in the cavity 21 expands, the movable plate 41 is subjected to pressure from the first cavity section 46, thereby moving in the direction of the pressure relief opening 48, and by compressing the gas in the second cavity section 47, a larger space volume is provided for the first cavity section 46, so that the pressure in the cavity 21 is absorbed and balanced.

However, when the gas in the second chamber section 47 is pressurized to a certain extent, the pressure in the second chamber section 47 is relatively high, so that the movable plate 41 cannot move continuously, and the space volume of the first chamber section 46 cannot be increased continuously; at this time, part of the gas needs to be discharged through the pressure relief opening 48 to reduce the pressure in the second cavity section 47, specifically, the pressure relief opening 48 is provided with a pressure relief valve, and the pressure relief valve can be opened to communicate the second cavity section 47 with the external air, so that the second cavity section 47 is depressurized.

Further, the cooling assembly comprises a heat dissipation main body 1, and the heat dissipation main body 1 is provided with a cooling channel group for the cooling pipe 3 to penetrate through; specifically, one end of the cooling tube 3 is communicated with the first port 22, and the other end of the cooling tube 3 penetrates through the cooling channel group and is penetrated out of the cooling channel group to be communicated with the second port 23.

In this way, the cooling pipe 3 is arranged in the heat dissipation main body 1 in a penetrating way, so that the runner and the heat dissipation structure are combined into a whole, and the heat dissipation is performed by utilizing the space to the maximum extent. During the flow of the cooling medium in the cooling tube 3, the heat dissipating body 1 is thermally connected to the cooling tube 3 so as to absorb heat of the cooling medium in the cooling tube 3, so that the cooling medium flows back to the cavity 21 after dissipating heat.

The cooling tube 3 is a hollow tube made of metal, such as a hollow copper tube. In the liquid cooling radiator in the prior art, the heat exchange box 2 and the radiating fin group are connected by adopting a rubber pipe, and the heat exchange box 2 and the radiating fin group form a cooling loop through the rubber pipe, and as the radiating fins cannot be arranged at the rubber pipe, a certain distance is often reserved between the heat exchange box 2 and the radiating main body 1, so that the structure of the radiator is loose and not concentrated. In this embodiment, adopt cooling tube 3 of metal material, set up cooling channel in heat dissipation main part 1, cooling tube 3 mostly embeds in the cooling channel, has shortened the transmission distance of coolant, has saved the volume that cooling tube 3 occupy when exposing the assembly, and whole cooling system links together through cooling tube 3 comparatively compactly to can effectively utilize the space to dispel the heat, promote radiating efficiency.

Further, referring to fig. 1 and 2, the cooling assembly further includes a fan assembly 6, and specifically, the fan assembly 6 includes a fan housing 61 and a fan 62; the fan assembly 6 is provided at one side of the heat dissipating body 1 and serves to guide an air flow toward the heat dissipating body 1.

The fan housing 61 is used for intensively blowing the air flow of the fan 62 toward the heat dissipating body 1, so as to improve the heat dissipating effect of the fan 62.

In use, since the cooling tube 3 is mostly built in the heat dissipating body 1, during the process of the cooling medium flowing in the cooling tube 3 after leaving the heat exchange box 2, a part of heat is taken away by the air flow generated by the fan 62, and a part of heat is transferred to the heat dissipating body 1 through heat transfer and is taken away by the air flow on the heat dissipating body 1.

Further, referring to fig. 3 and 4, the heat exchange case 2 includes a cover plate 25, the heat dissipating body 1 is mounted on the cover plate 25, and the heat dissipating body 1 has a bottom surface facing the cover plate 25.

In order to avoid that the pressure relief device occupies more space during assembly, the heat dissipating main body 1 and the heat exchanging box 2 are both arranged in the shape of step parts, an assembly interval for accommodating the pressure relief assembly 4 is arranged between the two step parts, and the assembly interval is positioned in the air outlet direction of the fan assembly 6. Therefore, the assembly of the pressure relief assembly 4 and the heat exchange box 2 can be ensured to be compact, and the whole volume of the radiator module is kept unchanged; and is also capable of carrying away the heat of the pressure relief assembly 4 by the air flow blown out by the fan assembly 6.

In addition, since the pressure relief assembly 4 is mounted on the heat exchange tank 2, when the temperature in the heat exchange tank 2 increases, the cooling medium expands by heating and enters the first cavity section 46 in the pressure relief main body, which causes the temperature of the pressure relief assembly 4 to increase; the pressure relief assembly 4 is arranged in the air outlet direction of the fan assembly 6, and when the air flow passes through the pressure relief assembly 4, part of heat of the pressure relief assembly 4 can be taken away, so that heat dissipation of the pressure relief assembly 4 is realized.
