DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. Now, with reference to the drawings, the preferred embodiments of the present utility model will be described in detail.

[0026] An embodiment of the present utility model provides a liquid cooling pad 100. As Figures 1 to 4 shown, the liquid cooling pad 100 includes a pad body 10 and a radiator 20. The pad body 10 has a flow space inside for the cooling medium to flow. The radiator 20 is installed on the pad body 10. The radiator 20 includes a liquid storage structure 22, a liquid pump 23, a liquid pipeline 24, and a heat dissipation component 21. The liquid storage structure 22 has a liquid storage cavity 221 inside for storing the cooling medium. The liquid pipeline 24 is connected to the liquid pump 23, the flow space, and the liquid storage cavity 221, so that the liquid pump 23 can drive the cooling medium to circulate between the flow space and the liquid storage cavity 221. The heat dissipation component 21 is installed beside the liquid storage structure 22 and is used to dissipate heat from the cooling medium in the liquid storage cavity 221.

[0027] The liquid cooling pad 100 of the present utility model realizes a liquid cooling pad 100 with the radiator 20 integrally arranged with the pad body 10 by installing the radiator 20 on the pad body 10. The radiator 20 includes a liquid storage structure 22, a liquid pump 23, a liquid pipeline 24, and a heat dissipation component 21. The liquid storage structure 22 has a liquid storage cavity 221 inside for storing the cooling medium. The liquid pipeline 24 is connected to the liquid pump 23, the flow space, and the liquid storage cavity 221, so that the liquid pump 23 can drive the cooling medium to circulate between the flow space and the liquid storage cavity 221. The heat dissipation component 21 is installed beside the liquid storage structure 22 and is used to dissipate heat from the cooling medium in the liquid storage cavity 221. When the user uses the liquid cooling pad 100, the liquid cooling pad can be directly placed on the back and / or buttocks position for cooling, which is convenient to use. When the liquid cooling pad 100 needs to be moved, the liquid cooling pad 100 can be picked up with one hand, which is convenient for handling and carrying.

[0028] In some embodiments, the radiator 20 can be detachably installed in the pad body 10. When the pad body 10 gets dirty, the radiator 20 can be disassembled to clean the pad body 10, or the pad body 10 can be replaced, which makes it convenient for the user to clean or replace the pad body 10. In other embodiments, the radiator 20 is fixedly installed in the pad body 10.

[0029] In this embodiment, as Figure 1 shown, the radiator 20 further includes a housing 25. The liquid storage structure 22, the liquid pump 23, and the heat dissipation component 21 are all arranged inside the housing 25. The housing 25 is provided with an air inlet 251 and an air outlet 252 communicating with its internal space. The heat dissipation structure includes a fan 211 and heat dissipation fins 212. The heat dissipation fins 212 are installed in the air inlet direction or the air outlet direction of the fan 211, and the heat dissipation fins 212 are thermally connected to the liquid storage structure 22.

[0030] Specifically, the heat dissipation fins 212 of this embodiment are thermally connected to the liquid storage structure 22, so the heat dissipation fins 212 can be used to take away the heat of the cooling medium in the liquid storage chamber 221, thereby cooling the cooling medium. When the fan 211 rotates, it will guide the low-temperature gas outside the housing 25 to enter the housing 25 through the air inlet 251 and blow towards the heat dissipation fins 212, thereby taking away the heat on the heat dissipation fins 212, so that the heat dissipation fins 212 and the fan 211 can continuously and efficiently cool the cooling medium. The gas passing through the heat dissipation fins 212 will heat up and be discharged from the housing 25 through the air outlet 252.

[0031] In a specific embodiment, as Figure 4 shown, the heat dissipation assembly 21 further includes a thermoelectric cooler 27. The cold surface of the thermoelectric cooler 27 is attached to the liquid storage structure 22 to absorb heat from the cooling medium with a relatively high temperature in the liquid storage structure 22, and the hot surface is attached to the heat dissipation fins 212 to release the absorbed heat to the heat dissipation fins 212.

[0032] By implementing this embodiment, the heat exchange efficiency between the heat dissipation fins 212 and the cooling medium can be effectively improved. Compared with the embodiment without the thermoelectric cooler 27, the temperature of the cooling medium can be further reduced, improving the user's comfort.

[0033] In this embodiment, as Figures 1 to 4 shown, the radiator 20 further includes a partition plate 26. The partition plate 26 is arranged between the air inlet 251 and the air outlet 252. An air inlet chamber 253 is formed between the partition plate 26 and the air inlet 251. The heat dissipation assembly 21 is installed in the installation space between the partition plate 26 and the air outlet 252. An opening 2531 is provided on the wall of the air inlet chamber 253 to communicate the air inlet chamber 253 with the installation space, and the fan 211 is installed at the opening 2531. Among them, the rotation axis of the fan 211 extends in the first direction (such as the X direction shown in Figure 4 ), and the ratio of the projected area of the air inlet chamber 253 in the first direction to the projected area of the fan 211 in the first direction is greater than or equal to 2.

[0034] Specifically, the partition plate 26 is disposed within the housing 25 and located between the air inlet 251 and the air outlet 252, which can separate the air inlet chamber 253 from the installation space. By providing an opening 2531 on the wall of the air inlet chamber 253, the air inlet chamber 253 is connected to the installation space. This setting restricts the air flow direction to discharge from the air inlet 251 to the opening 2531 and then to the air outlet 252. The ratio of the projected area of the air inlet chamber 253 in the first direction to the projected area of the fan 211 in the first direction is greater than or equal to 2. Therefore, the size of the air inlet chamber 253 in this embodiment is relatively large. Compared with the embodiment where the ratio of the projected area of the air inlet chamber 253 in the first direction to the projected area of the fan 211 in the first direction is equal to 1 or slightly greater than 1, more air can enter the air inlet chamber 253 in this embodiment, which can accelerate the heat dissipation of the fan 211 to the heat dissipation fins 212.

[0035] In this embodiment, as Figure 1 and Figure 4 shown, the air inlet chamber 253 extends in the second direction (such as the Y direction shown in Figure 4 ), so that the air inlet chamber 253 is in a long strip shape. The ratio of the length of the air inlet chamber 253 in the second direction to the length of the air inlet 251 in the second direction is greater than or equal to 0.7, and the first direction is perpendicular to the second direction.

[0036] Specifically, since the air inlet chamber 253 extends in a long strip shape in the second direction, the air inlet chamber 253 is relatively long. Also, because the length ratio of the air inlet 251 to the air inlet chamber 253 is greater than or equal to 0.7, the air inlet 251 is also relatively long. Compared with a short air inlet, it can effectively avoid the situation where the air inlet 251 is blocked when the user uses a liquid cooling pad, ensuring the air volume entering the radiator 20, and thus achieving a better heat dissipation effect.

[0037] In this embodiment, as Figure 2 and Figure 3 shown, the pad body 10 includes a seat cushion area 11 and a backrest area 12 connected to the seat cushion area 11, and the radiator 20 is installed on the side of the seat cushion area 11 away from the backrest area 12.

[0038] Specifically, if the radiator 20 is installed on the side of the pad body 10, then the radiator 20 will occupy the sitting width. Exemplarily, if the original seat is only 70 CM wide, the radiator 20 will occupy a part of the width, which makes the available sitting width of the seat only 60 CM or even 50 CM, and the sitting experience will be very poor. To solve this technical problem, in this embodiment, the radiator 20 is installed on the side of the seat cushion area 11 away from the backrest area 12, effectively solving the problem of the sitting width.

[0039] In this embodiment, as Figure 4As shown, the liquid storage structure 22 includes an annular retaining edge 261 and a cover plate 222. The annular retaining edge 261 is disposed on the side of the partition plate 26 facing away from the air inlet 251 and is integrally formed with the partition plate 26 to define a receiving groove 223. The cover plate 222 is covered at the receiving groove 223 to cooperate with the annular retaining edge 261 to define a liquid storage cavity 221, and the heat dissipation fins 212 are thermally connected to the cover plate 222.

[0040] Specifically, if the annular retaining edge 261 is separately provided from the partition plate 26, a bottom plate needs to be provided to seal the bottom of the annular retaining edge 261, thereby defining the receiving groove 223. By implementing this embodiment, the annular retaining edge 261 and the partition plate 26 are integrally formed, and the partition plate 26 serves as the bottom of the receiving groove 223, which can reduce the thickness of one bottom plate. Thus, it can be seen that by implementing this embodiment, the thickness of the radiator 20 can be made smaller.

[0041] In this embodiment, as Figure 1 shown, the air inlet 251 and the air outlet 252 are oppositely disposed on both sides of the housing 25, and the air inlet 251 and the air outlet 252 are located in the extending direction of the rotation axis of the fan 211.

[0042] Specifically, the positions of the air inlet 251 and the air outlet 252 are set in the extending direction of the rotation axis of the fan 211, which can effectively reduce the air resistance and thus improve the heat dissipation effect.

[0043] In this embodiment, as Figure 4 shown, the heat dissipation fins 212 include a first fin portion 2121 and a second fin portion 2122. The first fin portion 2121 is installed in the first direction of the liquid storage structure 22, the second fin portion 2122 is thermally connected to the first fin portion 2121 and is located in the second direction of the first fin portion 2121, and the fan 211 is installed in the second direction of the liquid storage structure 22 so that the fan 211 and the second fin portion 2122 are oppositely disposed in the first direction; wherein, the first direction is perpendicular to the second direction.

[0044] Specifically, in the traditional radiator 20, both the liquid storage structure 22 and the heat dissipation fins 212 are arranged on the rotation axis of the fan 211. This setting makes the thickness of the radiator 20 relatively thick, and since the liquid storage structure 22 blocks the extension direction of the axis of the fan 211, the flow resistance is relatively large. In the present utility model, the heat dissipation fins 212 are divided into a first fin portion 2121 and a second fin portion 2122. The first fin portion 2121 is installed in the first direction of the liquid storage structure 22, and the second fin portion 2122 is thermally connected to the first fin portion 2121 and is located in the second direction of the first fin portion 2121. The fan 211 is installed in the second direction of the liquid storage structure 22, so that the fan 211 and the second fin portion 2122 are oppositely arranged in the first direction. Compared with the traditional radiator 20, this setting can reduce the thickness of the entire radiator 20 and has a smaller wind resistance, achieving two goals with one action.

[0045] In this embodiment, as Figure 4 shown, the liquid pump 23 is arranged on the side of the liquid storage structure 22 away from the fan 211.

[0046] If the liquid pump 23 is arranged on the side of the fan 211 away from the liquid storage structure 22, the length of the liquid pipeline 24 needs to be lengthened, and the flow path of the cooling medium is also lengthened accordingly, and the liquid circulation rate of the cooling medium will also become slower. If the liquid pump 23 is arranged between the fan 211 and the liquid storage structure 22, and the cooling medium is cooled by the heat dissipation fins 212 and the fan 211, the length of the heat dissipation fins 212 needs to be lengthened, increasing the cost. Therefore, in this embodiment, the liquid pump 23 is arranged on the side of the liquid storage structure 22 away from the fan 211, shortening the flow path of the incoming and outgoing cooling medium, which is equivalent to accelerating the flow of the cooling medium, thereby accelerating the liquid circulation rate of the cooling medium between the liquid storage structure 22 and the flow space.

[0047] In this embodiment, as Figure 4 shown, the liquid pipeline 24 includes: two first pipe bodies 241, a second pipe body 242, and a third pipe body 243. The two ends of the first pipe body 241 are respectively communicated with the liquid storage cavity 221 and the flow space, the two ends of the second pipe body 242 are respectively communicated with the liquid inlet end of the liquid pump 23 and the flow space, and the two ends of the third pipe body 243 are respectively communicated with the liquid outlet end of the liquid pump 23 and the liquid storage cavity 221.

[0048] Specifically, the first pipe body 241 is used to connect the liquid storage cavity 221 and the flow space, and convey the cooling medium in the liquid storage cavity 221 to the flow space. The second pipe body 242 is used for the liquid inlet end of the liquid pump 23 and the flow space. The liquid pump 23 pumps out the cooling medium in the flow space. The third pipe body 243 is used to connect the liquid outlet end of the liquid pump 23 and the liquid storage cavity 221. The cooling medium pumped out by the liquid pump 23 from the flow space is conveyed back to the liquid storage cavity 221 through the liquid inlet end of the liquid pump 23, so as to achieve liquid circulation. Arranging two first pipe bodies 241 can accelerate the conveying rate of the cooling medium from the liquid storage cavity 221 to the flow space, and further improve the circulation efficiency of the entire liquid circulation.

[0049] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. For those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some of the technical features can be equivalently replaced; and all such modifications and replacements should fall within the protection scope of the appended claims of the present invention.
