Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, in particular to a four-sided liquid cooling structure, a liquid cooling device and an electrical equipment. Background Art

[0002] During the use of electrical equipment, a large amount of heat will be generated. In order to make the equipment operate normally, heat dissipation treatment needs to be carried out on the equipment. Taking an electric vehicle as an example, in order to control the temperature of the battery pack in the battery box, a liquid cooling device is usually arranged in the battery box for cooling and heat dissipation. In the existing heat dissipation structure of the battery box, its main structure is composed of a box body and cooling pipes connected to the box body. The box body is generally composed of a frame structure with an open upper end and an upper cover connected to the open end of the frame. The cooling pipes are generally arranged at the bottom or side wall of the frame. During use, the battery is installed in the frame through the open end of the frame, and then the upper cover is fixed at the open end, and the battery is cooled by the cooling pipes.

[0003] Although the box body in the prior art can dissipate heat from power components such as batteries, in actual use, on the one hand, it is necessary to install power components such as batteries into the frame from the open end, and then fix the upper cover, etc., and the operation is relatively complicated; at the same time, the structural strength of the upper cover is low, the protection effect on power components is average, and no cooling structure is provided on the upper cover. Therefore, the upper cover cannot play a heat dissipation role for power components such as batteries, resulting in limited cooling and heat dissipation effect of the box body on power components. Summary of the Utility Model

[0004] The utility model aims to provide a four-sided liquid cooling structure, a liquid cooling device and an electrical equipment to solve the problems of complex structure and poor heat dissipation effect in cooling power components in the prior art.

[0005] To achieve the above technical purpose, the utility model adopts the following technical solution: A four-sided liquid cooling structure includes a frame body having at least four base surfaces. An installation cavity penetrating the frame body along the length direction of the frame body is provided in the frame body, and at least one set of liquid cooling groups along the length direction of the frame body is provided on each base surface. The liquid cooling group has a liquid inlet end and a liquid outlet end, and all the liquid cooling groups are arranged in sequence along the outer contour line of the frame body; both ends of the frame body are fixedly connected with steering parts, and steering flow channels are provided in the steering parts. The liquid outlet end of the liquid cooling group is communicated with the liquid inlet end of the adjacent liquid cooling group through the steering flow channel.

[0006] The principle of this solution is as follows: In this application, an installation cavity is provided inside the frame along the length direction of the frame. During use, the power components in the prior art can be pushed from the end of the frame into the installation cavity, and the installation of the power components is fast and convenient. In addition, liquid cooling groups are provided on all the base surfaces in the frame, so that the power components placed in the installation cavity can be cooled from all four sides, effectively improving the heat dissipation effect of the entire structure. A turning part is connected to the end of the frame, and by using the turning flow channel provided inside the turning part, adjacent liquid cooling groups are sequentially connected to form a unidirectional flowing cooling channel. During use, only the cooling medium in the prior art (such as coolant or cooling gas, etc.) needs to be conveyed to the liquid inlet end of one of the liquid cooling groups, and the cooling medium can automatically flow through all the cooling groups in sequence, thereby playing a good cooling and heat dissipation effect on the power components inside the frame.

[0007] The beneficial effects of this solution are as follows:

[0008] 1. It has high cooling and heat dissipation performance: Compared with the box structure in the prior art that cannot dissipate heat from the top of the power components, in the frame structure of this application, cooling groups are provided on each base surface, and each can play a role in cooling and dissipating heat for the power components in the installation cavity. Therefore, by adopting the technical solution in this application, heat dissipation can be carried out more efficiently and quickly. At the same time, since the turning part is located at the end of the frame in this application, when the cooling medium flows into the turning flow channel in the turning part, the flow direction changes, so that the flow velocity of the cooling medium decreases, which is conducive to the cooling medium contacting and exchanging heat for a longer time, making the cooling medium play a better cooling effect and further enhancing the cooling and heat dissipation effect.

[0009] 2. The installation of power components is more convenient and fast: Compared with the need to disassemble and assemble the upper cover to complete the disassembly and assembly of power components in the prior art, in this application, it is only necessary to push the power components from the end of the frame into the installation cavity, and the installation of the power components is more convenient and efficient.

[0010] 3. The overall structural strength of the frame is better: Compared with the box with an upper cover in the prior art, not only is the connection of the upper cover inconvenient, but more importantly, the strength of the upper cover is low and it cannot play a good protective role for the power components inside the box. In this application, the frame is formed by sequentially and fixedly connecting at least four base surfaces, so the structural strength in the four directions of the frame is the same, and it can play a better protective role for the power components in the installation cavity.

[0011] 4. The cooling effect is stable: In this application, all the base surfaces are fixedly connected to each other to form the frame, and two turning parts are respectively fixedly connected to both ends of the frame. Therefore, the liquid cooling group is in a stable closed-loop state, and problems such as leakage are not likely to occur during use, making the cooling effect of the entire cooling structure very stable.

[0012] Preferably, as an improvement, at least one cooling channel is provided in the liquid cooling group. When the number of cooling channels is greater than or equal to two, all the cooling channels are arranged in parallel.

[0013] In this solution, a cooling channel is provided in the liquid cooling group. The cooling channel is arranged along the length direction of the housing. When the cooling medium flows through the cooling channel, it can cool and dissipate heat from the power components in the installation cavity. Additionally, when the number of cooling channels in the liquid cooling group is multiple, the multiple cooling channels are arranged in parallel with each other, enabling the multiple cooling channels in the liquid cooling group to be conveniently arranged on the base surface, and the processing and forming are simpler.

[0014] Preferably, as an improvement, the cooling channel is integrally formed on the outer side of the base surface.

[0015] In this solution, the cooling channel is integrally formed on the outer side of the base surface. On the one hand, the integral formation of the cooling channel not only makes the processing and manufacturing of the cooling channel more efficient. On the other hand, the cooling channel is integrally formed with the base surface. When the cooling medium flows through the cooling channel, it can directly contact the base surface, enabling the cooling medium to complete heat exchange more efficiently, thereby enhancing the heat exchange effect of the cooling structure. Moreover, with the integral formation of the cooling channel, compared with the method of welding cooling pipes in the prior art, the pipe diameter of the cooling channel is uniform and there is no leakage, etc., enabling the cooling channel to provide more stable cooling and heat dissipation.

[0016] Preferably, as an improvement, all the base surfaces of the housing are integrally formed, and the thickness of the base surface is greater than or equal to 1.5 mm.

[0017] In this solution, all the base surfaces are integrally formed to form the housing, which not only improves the processing and manufacturing efficiency of the housing, but also the connection strength between adjacent base surfaces is very high due to the integral formation of multiple base surfaces. The structure of the housing is very stable during use. And in this solution, the thickness of the base surface is greater than or equal to 1.5 mm, making the base surface have high strength and being able to effectively protect the power components in the installation cavity.

[0018] Preferably, as an improvement, the cross-section of the cooling channel is one or a combination of a circle, a sector, an ellipse, or a polygon.

[0019] In this solution, a cooling channel with a suitable cross-sectional shape is selected according to the processing and forming difficulty and the heat dissipation efficiency requirements to meet products with different heat dissipation needs. For example, for products with high heat dissipation efficiency, an elliptical cross-sectional cooling channel with a large cross-sectional area can be selected. Another example is that a cooling channel with a circular cross-section can be selected for convenient processing and forming.

[0020] Preferably, as an improvement, the steering member includes a steering collar fixedly connected to the end of the frame body. A plurality of drainage cavities are provided on the inner wall of the steering collar, and a barrier portion is provided between adjacent drainage cavities. A steering flow channel is formed between the drainage cavity and the frame body.

[0021] In this solution, by machining and forming the drainage cavity on the inner wall of the steering collar, when the steering collar is fixedly connected to the end of the frame body, a steering flow channel can be formed with the frame body. Moreover, by using the barrier portion provided inside the steering collar, adjacent drainage cavities are blocked from each other. Thus, after the steering collar is fixedly connected to the end of the frame body, the barrier portion can prevent the two liquid inlet ends of adjacent liquid cooling groups from being connected, ensuring that only a single one-way flow channel can be formed between adjacent liquid cooling groups, so that all liquid cooling groups can be connected in sequence and the cooling structure can efficiently achieve cooling and heat dissipation.

[0022] Preferably, as an improvement, the end of the frame body is provided with a mounting boss, and the steering collar is fixedly connected to the mounting boss.

[0023] In this solution, by providing the mounting boss at the end of the frame body, the mounting boss can not only play a positioning role during the fixed connection of the steering collar, making the installation and fixation of the steering collar more accurate and convenient; at the same time, after setting the mounting boss, relying on the stepped structure of the mounting boss, the steering collar can be more firmly fixedly connected to the frame body.

[0024] A liquid cooling device includes the described four-sided liquid cooling structure.

[0025] In this solution, by providing the described four-sided liquid cooling structure on the liquid cooling device, the cooling and heat dissipation effect of the liquid cooling device is effectively improved.

[0026] Preferably, as an improvement, a liquid inlet interface and a liquid outlet interface are connected to the steering member. The liquid inlet interface is communicated with the liquid inlet end of one of the liquid cooling groups, and the liquid outlet interface is communicated with the liquid outlet end of the adjacent liquid cooling group. The liquid inlet interface, all the liquid cooling groups, and the liquid outlet interface form a one-way flowing cooling channel.

[0027] In this solution, the cooling medium is input into the liquid inlet end of the liquid cooling group through the liquid inlet interface, and then the cooling medium flows through all the liquid cooling groups in sequence and flows out through the liquid outlet interface, so that the liquid cooling group can continuously cool and dissipate heat from the electrical components in the installation cavity.

[0028] An electrical device includes the described four-sided liquid cooling structure or the described liquid cooling device.

[0029] By providing a four-sided liquid cooling structure or a liquid cooling device in the electrical device, the cooling and heat dissipation performance of the electrical device is high, and the electrical device can be efficiently cooled and dissipated. Description of the Drawings

[0036] The following is a further detailed description through specific implementation manners:

[0037] The reference numerals in the accompanying drawings of the specification include: base surface 1, installation cavity 2, cooling channel 3, steering collar 4, drainage cavity 401, blocking portion 402, installation boss 5, liquid inlet interface 6, and liquid outlet interface 7.

[0038] Embodiment 1

[0039] As shown in the attached Figure 1 and Figure 2 : A four-sided liquid cooling structure includes a frame having at least four base surfaces 1. In this embodiment, the frame is composed of four base surfaces 1, so that an installation cavity 2 is formed inside the frame and runs through the frame along the length direction of the frame. When in use, power components such as batteries in the prior art can be installed in the installation cavity 2. At the same time, the four base surfaces 1 are integrally formed by extrusion, so that the frame structure composed of the four base surfaces 1 has better strength. The thickness of each base surface 1 is equal and greater than or equal to 1.5 mm. In this embodiment, it is preferably 2 mm, further ensuring that the frame has sufficient structural strength.

[0040] Combined with Figure 1 and Figure 4 , at least one set of liquid cooling groups arranged along the length direction of the frame is provided on each base surface 1. The liquid cooling group has a liquid inlet end and a liquid outlet end, and at least one cooling channel 3 is provided in the liquid cooling group. When the number of cooling channels 3 in the liquid cooling group is greater than or equal to two, all the cooling channels 3 are arranged in parallel along the length direction of the frame. The number of liquid cooling groups provided on each base surface 1 is two, and all the liquid cooling groups are arranged in sequence along the outer contour line of the frame, and the number of cooling channels 3 in each liquid cooling group is seventeen.

[0041] Meanwhile, as Figure 3 shown, for the convenience of processing and the structural stability of the cooling channel 3, the cooling channel 3 in this embodiment is integrally formed on the outer wall of the base surface 1 by an extrusion molding method, and the cross-section of the cooling channel 3 is one or more combinations of a circle, a sector, an ellipse, or a polygon. For the convenience of processing, the cross-section of the cooling channel 3 in this embodiment is circular, and the top surface of the base surface 1 is set to be wavy to match the sector cross-section of the cooling channel 3, which not only increases the heat dissipation area of the top surface of the base surface 1, effectively improves the heat dissipation efficiency of the cooling structure, but also forms a ribbed strengthening structure, making the structure of the base surface 1 stronger.

[0042] Combined with Figure 1 and Figure 2 , steering members are fixedly connected to both ends of the frame body. A steering flow channel is provided inside the steering member. The liquid outlet end of the liquid cooling group is communicated with the liquid inlet end of the adjacent liquid cooling group through the steering flow channel. Specifically, the steering member is a steering collar 4 fixedly connected to the end of the frame body by friction stir welding. And in order to more conveniently and accurately fix the steering collar 4, convex structures are integrally formed at both ends of the base surface 1. The four convex structures at the same end of the four base surfaces 1 enclose an installation boss 5, and the steering collar 4 is sleeved on the installation boss 5. Combined with Figure 3 , a number of drainage cavities 401 equal to the number of liquid cooling groups are opened on the inner wall of the steering collar 4, that is, two drainage cavities 401 are opened on each inner wall surface. A blocking portion 402 is provided between adjacent drainage cavities 401. A transition flow channel matching the cooling channel 3 is opened on the steering collar 4. After the steering collar 4 is fixed on the installation boss 5, the transition flow channel is communicated with the drainage cavity 401 and the cooling channel 3. The steering flow channel as described above is formed between the drainage cavity 401 and the installation boss 5. Through the steering collar 4 structures at both ends, the liquid inlet ends and liquid outlet ends of all liquid cooling groups are connected end to end in sequence to form a flow channel structure as Figure 5 shown.

[0043] A liquid cooling device, as Figure 6 shown, includes the above-mentioned four-sided liquid cooling structure. Among them, a liquid inlet interface 6 and a liquid outlet interface 7 are welded on the steering collar 4. The liquid inlet interface 6 is communicated with the liquid inlet end of one of the liquid cooling groups, and the liquid outlet interface 7 is communicated with the liquid outlet end of the adjacent liquid cooling group. The liquid inlet interface 6, all the liquid cooling groups, and the liquid outlet interface 7 form a unidirectional cooling channel. The cooling medium such as cooling water in the prior art is injected into the liquid inlet end of the corresponding liquid cooling group through the liquid inlet interface 6, and then the cooling medium flows through all the liquid cooling groups in sequence and then flows out through the liquid outlet interface 7. Since the cooling medium flows through the four base surfaces 1 in sequence, the power components in the installation cavity 2 can be quickly cooled and dissipated heat from top to bottom, left to right, so that the power components can work stably in a suitable temperature environment.

[0044] An electrical device includes the above-mentioned four-sided liquid cooling structure or a liquid cooling device, making the heat dissipation structure of the electrical device have high strength, stable structure and high heat dissipation efficiency.

[0045] Embodiment 2

[0046] The difference between Embodiment 2 and Embodiment 1 is that: in Embodiment 1, two sets of liquid cooling groups are arranged on each base surface 1. In this embodiment, the number of liquid cooling groups arranged on each base surface 1 is four groups. Correspondingly, four drainage cavities 401 are arranged on each inner wall surface of the steering collar 4, so that the four liquid cooling groups on the same base surface 1 are connected in sequence, increasing the number of turns of the cooling medium within the same base surface 1, thereby further slowing down the flow rate of the cooling medium and enhancing its cooling and heat dissipation effect.

[0047] Embodiment 3

[0048] The difference between Embodiment 3 and Embodiment 1 is that: in Embodiment 1, only one set of liquid inlet interface 6 and liquid outlet interface 7 are provided. In this embodiment, two sets of liquid inlet interface 6 and liquid outlet interface 7 are provided, dividing the liquid cooling groups in the entire frame into two equal parts. One set of liquid inlet interface 6 and liquid outlet interface 7 are respectively provided for the two equal parts of liquid cooling groups, thereby enhancing the uniformity of the cooling medium in cooling and dissipating heat from the electrical components within the frame.

[0049] The above are only the embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
