Description

Technical Field

[0001] The utility model relates to a container liquid cooling device and a container. Background Art

[0002] In the prior art, some containers use liquid cooling devices to cool down the equipment inside the container. For example, some energy storage containers use liquid cooling devices to dissipate heat from batteries in the container to ensure that the batteries can work normally. The operation of the liquid cooling device can be summarized as two processes: heat absorption and heat exchange. In the heat absorption process, the liquid cooling device absorbs and takes away the heat of the battery or other equipment through the cooling medium. In the heat exchange process, the cooling medium exchanges heat in the heat exchange system, so that the temperature of the cooling medium is reduced. This cycle is repeated to continuously cool down the battery or other equipment.

[0003] Chinese patent document CN202322076235.6 discloses a liquid-cooled air-conditioning unit for dissipating heat and cooling down a battery. The air-conditioning unit is provided with a refrigeration device, which includes a condenser and a fan for performing heat exchange operations. The condenser is arranged on one side of the fan along the exhaust direction of the fan. To ensure that the air is in full contact with the condenser and that the coolant is fully heat exchanged, a certain distance is required between the condenser and the fan to form a sufficiently large wind cavity. However, such an arrangement will increase the volume of the liquid-cooled air-conditioning unit, causing the air-conditioning unit to occupy a larger space. Utility Model Content

[0036] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. Obviously, the embodiments described in this application are only part of the embodiments of the present application, not all of them. Figures 1 to 4 A container liquid cooling device is shown, which absorbs the heat of the product to be cooled through the refrigerant, cools down the product to be cooled and dissipates the heat, then exchanges heat with the refrigerant whose temperature rises due to absorbing the heat, thereby lowering the temperature of the refrigerant, and then uses the refrigerant after heat exchange to absorb the heat of the product to be cooled, thus forming a cooling circuit, thereby continuously cooling the product to be cooled.

[0037] The container liquid cooling device includes a frame 1, a fan unit and a heat exchange component 3, wherein the frame 1 has an equipment cavity 101 and a heat exchange cavity 102, a device for forming a cooling circuit is arranged in the equipment cavity 101, and the heat exchange cavity 102 is used for heat exchange operation to reduce the temperature of the cooling medium. The heat exchange component 3 is arranged on the frame 1 and located in the heat exchange cavity 102, and the cooling medium exchanges heat with the air in the heat exchange cavity 102 in the heat exchange component 3. The fan unit includes a plurality of groups of fans 21 arranged on the frame 1, and the air inlet of the fan 21 is interconnected with the heat exchange cavity 102. Under the action of the fan, the external air and the air in the heat exchange cavity 102 can circulate, thereby continuously discharging hot air from the heat exchange cavity 102, and continuously sucking cold air into the heat exchange cavity 102, thereby realizing continuous heat exchange of the cooling medium.

[0038] In the first direction, the equipment cavity 101 is located on one side of the heat exchange cavity 102, and the axis 20 of the fan 21 extends along the second direction. The second direction is perpendicular to the first direction, and the circumferential cavity wall of the heat exchange cavity 102 is fully or partially covered with the heat exchange component 3. In this way, the functional areas of the liquid cooling device are clearly defined, which is convenient for daily maintenance, and a sufficiently large air cavity can be formed between the heat exchange component 3 and the fan 21. Compared with the prior art in which the heat exchange component 3 is arranged on one side of the fan 21 along the second direction, the size of the liquid cooling device along the second direction can be effectively reduced while improving the heat exchange efficiency, thereby reducing the size of the space occupied by the liquid cooling device and achieving the effect of saving space.

[0039] In this embodiment, the frame 1 is in the shape of a rectangular parallelepiped, and the equipment cavity 101 and the heat exchange cavity 102 are both in the shape of a rectangular parallelepiped. With such a configuration, the liquid cooling device can match the structure of most containers, and it is convenient to install the liquid cooling device and the container body. The equipment cavity 101 and the heat exchange cavity 102 of this embodiment are also configured in the shape of a rectangular parallelepiped, which can make full use of the space of the liquid cooling device, and refer to Figure 8 As shown, the volume of the equipment cavity 101 is smaller than the volume of the heat exchange cavity 102, and the liquid cooling device has a larger heat exchange space and a higher heat exchange efficiency.

[0040] In this embodiment, see Fig. 9 As shown, all heat exchange components 3 are located on the circumferential outer side of any fan 21, and are arranged at a distance from the circumferential outer side of any fan 21. A certain amount of distance usually needs to be set between the heat exchange component 3 and the fan 21 to form a sufficiently large wind cavity to more fully utilize the gas for heat exchange, thereby achieving a better heat exchange effect. In this embodiment, the heat exchange component 3 is arranged around the fan 21 to form a sufficiently large wind cavity. While meeting the distance requirements between the heat exchange component 3 and the fan 21, space in the second direction can be saved, thereby reducing the size of the liquid cooling device.

[0041] In this embodiment, the rectangular heat exchange cavity 102 has a first cavity wall and a second cavity wall arranged opposite to each other along a first direction, and a third cavity wall and a fourth cavity wall arranged opposite to each other along a third direction, and the first cavity wall, the third cavity wall, the second cavity wall and the fourth cavity wall are connected end to end to form a circumferential cavity wall of the heat exchange cavity, and the first cavity wall, the second cavity wall, the third cavity wall and the fourth cavity wall are all covered with a heat exchange component 3. With such an arrangement, the heat exchange area is larger and the heat exchange effect is better.

[0042] In this embodiment, all fans 21 are spaced apart along the third direction, and the third direction, the first direction, and the second direction are perpendicular to each other. The number of groups of fans 21 can be set to 2 to 5 groups. The fans 21 in this range will not generate much noise while driving the air inside and outside the heat exchange chamber 102 to circulate. In this embodiment, the fans 21 are provided with four groups spaced apart along the third direction. In other embodiments, see Fig.11 As shown, the fans 21 are provided with three groups spaced apart along the third direction. Fig.12 As shown, the fans 21 are provided in two groups spaced apart along the third direction.

[0043] In order to more clearly describe the structure of the container liquid cooling device and the relative positional relationship between various structures, it is assumed that the axis 20 of the fan 21 extends along the front-to-back direction, that is, the second direction is the front-to-back direction, and the fan 21 exhausts air forward, and the first direction is assumed to be the left-right direction, and the coordinate system is established in sequence. In this way, the third direction is the up-down direction, see Figure 1As shown, the equipment chamber 101 is arranged on the right side of the heat exchange chamber 102, the fan group is arranged on the front side of the frame 1, and the fan 21 is located on the front side of the heat exchange chamber 102, and four groups of fans 21 are distributed at intervals in the up and down directions.

[0044] See also Figures 2 to 5 As shown, in this embodiment, the frame 1 is provided with an air inlet 103 for air to flow into the heat exchange chamber 102, and an air outlet 104 for gas to flow out of the heat exchange chamber 102. The fan 21 is arranged at the air outlet 104. Under the action of the fan 21, the hot air in the heat exchange chamber 102 is discharged, and the gas inside and outside the heat exchange chamber 102 is circulated. In this embodiment, the air inlet 103 is arranged on the peripheral side of the heat exchange chamber 102. With this arrangement, the heat exchange component 3 is located on the path of air flowing into the heat exchange chamber 102, and the heat exchange component 3 can be in more sufficient contact with the air. At the same time, since the air temperature at the air inlet 103 is lower and the gas flowability at the air inlet 103 is better, the heat exchange effect of the heat exchange component 3 is better. See. Figure 1 , Figure 2 and Figure 8 As shown, air inlets 103 are provided on the upper side and the left side of the heat exchange chamber 102. Specifically, the upper side and the entire left side of the heat exchange chamber 102 are air inlets 103 for gas to flow in. The area of ​​the air inlet 103 is larger, and more air can flow into the heat exchange chamber 102 for heat exchange.

[0045] In this embodiment, the frame 1 includes a frame body 11 composed of rods and side panels 12 fixed to the frame body 11. Part of the side panels 12 are provided with mesh holes, thereby forming an air inlet 103 with a filtering function.

[0046] In this embodiment, a barrier 13 is provided on the frame 1, and the barrier 13 extends along the third direction and separates the internal space of the frame 1 into an equipment cavity 101 and a heat exchange cavity 102 that are sequentially distributed along the first direction. Figures 6 to 8 As shown, the barrier member 13 of this embodiment is two support rods extending in the up-down direction and spaced apart in the front-back direction, and a horizontal connecting rod arranged between the two support rods.

[0047] In this embodiment, Figure 1 , Figure 2As shown, an air inlet 103 is also provided on the right side of the liquid cooling device, and external air can flow into the equipment cavity 101 from the air inlet 103 on the right side. The barrier 13 of this embodiment allows air to enter the heat exchange cavity 102 from the equipment cavity 101, so that the air can participate in the heat exchange operation along the path of first entering the equipment cavity 101 and then entering the heat exchange cavity 102, and can circulate under the action of the fan 21. In the present application, the heat exchange component 3 at least covers the side wall of the barrier 13 facing the heat exchange cavity 102, and the barrier 13 is located on the path of the airflow from the equipment cavity 101 to the heat exchange cavity 102, so that the heat exchange component 3 can be more fully in contact with the cold air, and the heat exchange effect of the heat exchange component 3 is better.

[0048] In this embodiment, air inlets 103 are also provided on both the front and rear sides of the equipment cavity 101. External air can enter the equipment cavity 101 through the front and rear air inlets 103, and enter the heat exchange cavity 102 from the equipment cavity 101, and then participate in the heat exchange of the cooling medium. The air entering the heat exchange cavity 102 from different air inlets 103 can collide with each other and form vortices in the heat exchange cavity 102, thereby extending the heat exchange time in the heat exchange cavity 102 and improving the heat exchange efficiency.

[0049] In this embodiment, the side plate 12 arranged on the rear side of the heat exchange chamber 102 can prevent air from directly entering the heat exchange chamber 102 from the rear, so that the air can only enter the heat exchange chamber 102 from the surrounding side of the heat exchange chamber 102, thereby limiting the air flow path. In this way, when the air enters the heat exchange chamber 102, it can more fully contact with the heat exchange component 3 on the surrounding side, thereby improving the heat exchange effect.

[0050] In this embodiment, the heat exchange component 3 has a cooling medium inlet and a cooling medium outlet. When heat exchange is performed, the cooling medium that is heated due to heat absorption enters the heat exchange component 3 from the cooling medium inlet, and the cooling medium flows in the heat exchange component 3. During this process, the air exchanges the heat of the cooling medium. The cooling medium after heat exchange flows out from the cooling medium outlet and continues to perform the heat absorption operation, thus completing a cooling cycle.

[0051] In this embodiment, the liquid cooling device also includes a heat exchange unit (not shown in the figure) disposed in the equipment cavity 101. The heat exchange unit is connected to the cooling medium inlet and the cooling medium outlet through a plurality of connecting pipes. The heat exchange unit can pass the cooling medium into the heat exchange component 3, and can also receive the cooling medium that has undergone the heat exchange treatment. In this embodiment, a compressor, a circulating pump, a condenser and other equipment are provided in the equipment cavity 101 to form a cooling circuit and to perform heat exchange operations.

[0052] In this embodiment, the barrier 13 is provided with an installation channel for the connecting pipe to pass through, and the installation channel connects the equipment cavity 101 and the heat exchange cavity 102. Figure 8As shown, the gap between the two support rods forms the above-mentioned installation channel, and the connecting pipe can pass through the gap between the two support rods and penetrate into the heat exchange cavity 102. In other embodiments, the installation channel can adopt other configuration forms.

[0053] In some embodiments, the heat exchange assembly 3 includes a plurality of condensers 31, each of which has a plurality of condensing tubes 311 spaced apart along the second direction. When heat exchange is performed, the cooling medium is introduced into the condensing tube 311 and performs heat exchange with the air in the heat exchange chamber 102, thereby exchanging the heat of the cooling medium and lowering its temperature. In some preferred embodiments, the setting direction of the condensing tube 311 is the same as the direction in which the fan 21 discharges the gas outward, so that the gas can more fully contact the condensing tube 311, thereby achieving a better heat exchange effect. In this embodiment, each condenser 31 includes a plurality of rows of condensing tubes 311 spaced apart from the inside of the heat exchange chamber 102 to the outside of the chamber, and each row of condensing tubes 311 includes a plurality of tubes spaced apart along the second direction, so that the heat exchange effect is further improved.

[0054] In some embodiments, the condenser tube 311 is a fin tube to improve the heat exchange efficiency. In some embodiments, the heat exchange component 3 is a microchannel heat exchanger.

[0055] In this embodiment, see Fig.10 As shown, the heat exchange assembly 3 includes two groups of condensers 31, each group of condensers 31 is U-shaped, and the two groups of condensers 31 are spliced ​​together to form a rectangular frame and are arranged on the circumferential cavity wall of the heat exchange cavity 102. Figure 8 As shown, the upper cavity wall, lower cavity wall, left cavity wall and right cavity wall of the heat exchange cavity 102 are all covered with heat exchange components 3. The rectangular frame-shaped condenser 31 matches the shape of the heat exchange cavity 102, is easy to install and fix, and maximizes the heat exchange area, which can improve the heat exchange effect.

[0056] In this embodiment, one end of the two groups of condensers 31 are connected to each other, and the condensing pipes 311 of the two groups of condensers 31 are arranged to be connected to each other. In this way, only one set of circulation equipment is required in the equipment chamber 101 to control the circulation of the cooling medium in the two groups of condensers 31, without the need to set a set of circulation equipment for each condenser 31. In other embodiments, the two groups of condensers 31 are independent of each other and are not connected, and two sets of circulation equipment are required in the equipment chamber 101 to control the circulation of the cooling medium in the two groups of condensers 31 respectively.

[0057] Although not shown in the figure, the utility model also provides a container, on which the above-mentioned liquid cooling device 100 is arranged, the liquid cooling device 100 is fixedly arranged on one side of the length direction of the container, the second direction is parallel to the length direction of the container, and the air outlet of the liquid cooling device 100 faces away from the container, and along the first direction, at least one side of the liquid cooling device 100 is not blocked, ensuring that air can enter the heat exchange cavity 102 from the air inlet 103. Specifically, the container is an energy storage container, which also includes a box body and an energy storage device, the energy storage device includes a plurality of battery modules, and the liquid cooling device 100 can dissipate heat from the battery modules.

[0058] In summary, in all the above-mentioned embodiments of the container liquid cooling device, the heat exchange component 3 covers the circumferential side wall of the heat exchange cavity, and the external air also enters the heat exchange cavity 102 from the circumference of the heat exchange cavity 102. In this way, when the air enters the heat exchange cavity 102, the air is fully in contact with the heat exchange component 3 and can exchange heat, thereby improving the heat exchange efficiency. There are multiple air inlets 103 and they are arranged in multiple directions. The air entering the heat exchange cavity 102 from different air inlets 103 can collide with each other, increasing the heat exchange time and improving the heat exchange efficiency. The heat exchange component 3 covers the circumferential side wall of the heat exchange cavity, and the liquid cooling device 100 does not need to form an air cavity by expanding the volume, thereby saving space.
