Description

Technical Field

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

[0002] Electrical equipment will generate a lot of heat during use. In order to make the equipment operate normally, the equipment needs to be cooled. Taking electric vehicles as an example, in order to control the temperature of the battery pack in the battery box, a liquid cooling device is usually installed in the battery box for cooling and heat dissipation. In the existing battery box heat dissipation structure, its main structure is composed of a box and a cooling pipe connected to the box. The box 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 pipe is generally arranged at the bottom or side wall of the frame. When in use, the battery is installed in the frame through the open end of the frame, and then the upper cover is fixed to the open end, and the cooling pipe is used to dissipate heat from the battery.

[0003] Although the box in the prior art can dissipate heat for 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., which is a complicated operation; at the same time, the structural strength of the upper cover is low, and the protection effect on the power components is general, and no cooling structure is provided on the upper cover, so the upper cover cannot dissipate heat for power components such as batteries, which makes the cooling and heat dissipation effect of the box on the power components limited.

[0004] In view of the problem of poor cooling and heat dissipation effect of the cooling structure in the prior art, the inventor improved the heat dissipation structure in the prior art by setting a four-sided frame structure with openings at both ends and a hollow interior, and setting cooling channels on the four faces of the four-sided frame structure, so that during use, the four faces of the frame can efficiently dissipate heat for the hollow internally installed batteries and other electrical components, effectively improving the heat dissipation performance of the entire cooling structure. Although the improved structure can effectively improve the heat dissipation performance, in actual application, since the four faces are integrally formed, when installing batteries and other electrical components, it is necessary to push the electrical components from the openings at both ends into the frame. For a heavy battery pack structure, the operation is inconvenient and laborious. At the same time, when pushing the electrical components into the frame, the electrical components are prone to wear on the inner wall of the frame and damage the frame. In severe cases, the cooling channel may rupture and cause leakage of the cooling medium. Therefore, it is necessary to further improve the cooling structure to improve the convenience and safety of the cooling structure during use. Utility Model Content

[0005] The utility model aims to provide a spliced ​​four-sided liquid cooling structure, a liquid cooling device and an electrical device, so as to solve the problem that the cooling structure in the prior art is inconvenient to operate and easy to be damaged during use.

[0006] In order to achieve the above-mentioned technical objectives, the utility model adopts the following technical solutions: a spliced ​​four-sided liquid cooling structure, including two U-shaped base bodies, a fixing part is fixedly connected between the two base bodies, so that the two base bodies form a four-sided frame structure with an installation cavity arranged inside; a plurality of liquid cooling groups are arranged along the length direction of the base body on the three sides of each base body, and the liquid cooling group has a liquid inlet end and a liquid outlet end; steering parts are fixedly connected at both ends of the base body, and a steering flow channel is provided in the steering part, and the liquid outlet end and the liquid inlet end of adjacent liquid cooling groups in the same base body are connected through the steering flow channel.

[0007] The principle of this solution is: in this application, by setting up two U-shaped seat bodies, when the two seat bodies are connected face to face using the fixing parts, a four-sided frame structure with openings at both ends and a hollow interior can be formed, so that the two seat bodies can form an installation space for installing electrical components such as batteries in the prior art; since the two seat bodies are both U-shaped, in the actual installation process of electrical components such as batteries, the electrical components can be hoisted into the U-shaped structure of one of the seat bodies before the two seat bodies are fixedly connected, and then the other seat body can be fixedly connected to the seat body where the electrical components have been placed, so that the installation process of the electrical components can be conveniently completed.

[0008] In addition, in the present application, several groups of liquid cooling groups are arranged on each surface of each seat body, and steering parts are fixedly connected at both ends of the seat body. The steering flow channel formed by the steering parts is used to connect the liquid outlet ends and liquid inlet ends of adjacent liquid cooling groups in the same seat body, so that all liquid cooling groups on the three surfaces of the same seat body can be connected in sequence to form a unique flow channel. When in use, it is only necessary to transport the cooling medium in the prior art to the liquid inlet end of the liquid cooling group at the edge position, and the cooling medium can flow through all the liquid cooling groups in sequence to cool and dissipate the electrical components in the seat body.

[0009] The beneficial effects of this program are:

[0010] 1. The installation of power components is very convenient: Compared with the prior art method in which the entire frame structure is integrally formed, when installing power components, it is necessary to push the power components into the frame from one end of the frame, which is inconvenient and laborious. In this application, before installing the power components, the two seats are not fixed yet. At this time, it is only necessary to hoist the power components into one of the seats, and then fix the other seat to the seat where the power components have been installed. The entire installation process is more convenient to operate. Even if the weight of the power components is large, the installation operation can be completed conveniently and accurately, and the installation efficiency is effectively improved.

[0011] 2. Less damage to the frame structure: Compared with the prior art, when installing power components, the power components need to be pushed into the frame, and there is severe friction between the power components and the frame, causing the frame structure to be easily worn and unable to work normally. In this application, since the frame structure is formed by two U-shaped seats connected directly to each other, before installing the power components, the two seats have not been fixed, so the power components can be easily hoisted into one of the seats, and then the other seat is fixed on the seat. Therefore, during the installation of the power components, the power components will not have severe friction with the seat, thereby effectively reducing the damage to the seat.

[0012] 3. Highly efficient heat dissipation performance: In the present application, when the two base bodies are fixedly connected, they form a four-sided frame structure, and liquid cooling groups are arranged on the four sides of the four-sided frame structure. Therefore, the four sides can all have a cooling and heat dissipation effect on the electrical components in the frame structure, thereby efficiently dissipating the heat of the electrical components.

[0013] 4. Better uniformity of cooling and heat dissipation: In the present application, since both base bodies are provided with liquid cooling groups and steering parts, and the liquid cooling groups between the two base bodies are relatively independent, during the cooling process, the flow of cooling medium in the two base bodies is independent of each other and does not affect each other. Therefore, the technical solution in the present application is equivalent to providing two independent cooling channels in the frame structure, that is, cooling medium can be added from two different positions of the frame. Compared with the method of providing only one liquid inlet port in the prior art, the technical solution of the present application can provide more uniform heat dissipation for electrical components and effectively improve the uniformity of heat dissipation of the entire cooling structure.

[0014] Preferably, as an improvement, the fixing portion comprises an inserting protrusion and a slot which are inserted into each other, and the slot and the inserting protrusion are both arranged along the length direction of the seat body.

[0015] In the present solution, a fixing portion is formed by means of an inserting protrusion and a slot. When actually fixing the two seat bodies, it is only necessary to align the U-shaped opening ends of the two seat bodies so that the inserting protrusion is inserted into the slot. By means of the inserting cooperation between the inserting protrusion and the slot, not only can the two seat bodies be quickly and accurately docked, thereby fixing the facing ends of the two seat bodies by means of stir friction welding and the like in the prior art, but it can also help to maintain the relative position between the two seat bodies stable during the welding and fixing process of the two seat bodies, thereby improving the stability during the welding and fixing process, so that the two seat bodies can be fixed quickly, conveniently, accurately and stably.

[0016] Preferably, as an improvement, the two ends of the seat body for connecting with another seat body are respectively a first end and a second end, wherein the plug-in protrusion is arranged on the first end, and the slot is arranged on the second end.

[0017] In the present solution, a plug-in protrusion is provided on the first end of the seat body, and a slot is provided on the second end, that is, each seat body is provided with a plug-in protrusion and a slot. When the two seat bodies are fixedly connected, it is only necessary to flip one of the seat bodies so that the plug-in protrusion of one seat body is matched with the slot of the other seat body, and the slot on the seat body is matched with the plug-in protrusion on the other seat body. By adopting the method of the present solution, all the seat bodies can be set to the same structural size. Compared with the method of setting two plug-in protrusions on one of the seat bodies and two slots on the other seat body (this method requires the design of two sizes of products), it can effectively reduce the number of product types, thereby making the production and manufacturing of the seat body more convenient and efficient, and effectively reducing the production and manufacturing costs.

[0018] Preferably, as an improvement, a blocking portion is provided on the second end along the length direction of the seat body, the blocking portion is located at the opening end of the slot, and a groove that cooperates with the blocking portion is provided on the plug-in protrusion.

[0019] In this solution, the grooves and blocking parts structure that cooperate with each other are used so that when the two seat bodies are aligned before being fixedly connected, the other seat body can only be slid along the length direction of the seat body until the two seat bodies are connected. At this time, relying on the cooperation of the grooves and the blocking parts, the two seat bodies can be prevented from being displaced along the width direction of the seat bodies, further improving the accuracy of the relative position between the two seat bodies during the seat body welding and fixing process, improving the stability during welding and fixing, and making the welded frame structure more accurate.

[0020] 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 cooling channels are arranged in parallel; the cooling channel is integrally formed on the seat body, and the cross-section of the cooling channel is one or more combinations of circular, fan-shaped, elliptical or polygonal.

[0021] In the present solution, the cooling channel arranged in the liquid cooling group is integrally formed with the seat body. On the one hand, the cooling channel is integrally formed, which not only makes the processing and manufacturing of the cooling channel more efficient; on the other hand, the cooling channel is integrally formed on the seat body, and when the cooling medium flows through the cooling channel, it can directly contact the seat body, so that the cooling medium can complete heat exchange more efficiently, thereby improving the heat exchange effect of the cooling structure. Moreover, the cooling channel is integrally formed, and compared with the method of welding cooling pipes in the prior art, the pipe aperture of the cooling channel is uniform and will not leak, so that the cooling channel can provide more stable cooling and heat dissipation.

[0022] At the same time, when there are multiple cooling channels in the liquid cooling group, the multiple cooling channels are arranged in parallel with each other, so that the multiple cooling channels in the liquid cooling group can be conveniently arranged on the seat body, and the processing and forming is simpler; in addition, cooling channels with suitable cross-sectional shapes are selected according to the processing and forming difficulty and the heat dissipation efficiency requirements to meet products with different heat dissipation requirements. For example, for products with high heat dissipation efficiency, an elliptical cross-sectional cooling channel with a large cross-sectional area can be selected. For example, in order to facilitate processing and forming, a cooling channel with a circular cross-section can be selected.

[0023] Preferably, as an improvement, the steering member includes a steering collar fixedly connected to the end of the seat body, a plurality of drainage cavities are provided on the inner wall of the steering collar, a barrier portion is provided between adjacent drainage cavities, and a steering channel is formed between the drainage cavity and the seat body.

[0024] In the present solution, a drainage cavity is formed on the inner wall of the steering collar. When the steering collar is fixedly connected to the end of the seat body, a steering flow channel can be formed together with the seat body. The barrier portion provided on the inner side of the steering collar can block adjacent drainage cavities from each other. Therefore, after the steering collar is fixedly connected to the end of the seat body, the barrier portion can block the two liquid inlet ends of adjacent liquid cooling groups from being connected, ensuring that adjacent liquid cooling groups can only form a one-way flow channel, so that all liquid cooling groups can be connected in sequence and the cooling structure can efficiently achieve cooling and heat dissipation.

[0025] Preferably, as an improvement, a mounting boss is provided at the end of the seat body, and the steering ring is fixedly connected to the mounting boss.

[0026] In this solution, a mounting boss is provided at the end of the seat body. The mounting boss can not only play a positioning role during the fixing and connection process of the steering sleeve, but also make the installation and fixation of the steering sleeve more accurate and convenient; at the same time, after the mounting boss is provided, the steering sleeve can be more firmly fixed to the seat body by relying on the step structure of the mounting boss.

[0027] A liquid cooling device comprises the above-mentioned spliced ​​four-sided liquid cooling structure.

[0028] In this solution, by arranging the spliced ​​four-sided liquid cooling structure on the liquid cooling device, the cooling and heat dissipation effect of the liquid cooling device is effectively improved.

[0029] Preferably, as an improvement, the steering member is connected with a liquid inlet interface and a liquid outlet interface, the liquid inlet interface is connected to the liquid inlet end of the liquid cooling group at the first end, and the liquid outlet interface is connected to the liquid outlet end of the liquid cooling group at the second end, and the liquid inlet interface, all liquid cooling groups and liquid outlet interfaces on the same base form a unidirectional flow cooling channel.

[0030] 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 from the liquid outlet interface, so that the liquid cooling group can continuously cool and dissipate heat for the electrical components in the frame structure.

[0031] An electrical equipment comprises the spliced ​​four-sided liquid cooling structure or the liquid cooling device.

[0032] By arranging a spliced ​​four-sided liquid cooling structure or a liquid cooling device on the electrical equipment, the cooling and heat dissipation performance of the electrical equipment is improved, and the electrical equipment can be cooled and dissipated efficiently.

[0041] Embodiment 1

[0042] This embodiment is as shown in the attached Figure 1 and Figure 2As shown: a spliced ​​four-sided liquid cooling structure includes two U-shaped base bodies 1, the U-shaped openings of the two base bodies 1 are arranged opposite to each other, and a fixing part is fixedly connected between the U-shaped opening ends of the base bodies 1, so that the two base bodies 1 form a four-sided frame structure with four sides, and the four-sided frame structure is provided with an installation cavity 2 for installing electrical components such as batteries in the prior art.

[0043] Specific, combined Figure 3 The fixing part includes a plug-in protrusion 101 and a slot 102 that are plugged into each other. The plug-in protrusion 101 and the slot 102 are both arranged along the length direction of the seat body 1. In this embodiment, the two ends of one seat body 1 used to connect with the other seat body 1 are respectively the first end 103 and the second end 104. The plug-in protrusion 101 is integrally formed on the first end 103, and the slot 102 is integrally formed on the second end 104. In this embodiment, the plug-in protrusion 101 and the slot 102 are respectively arranged on the first end 103 and the second end 104 of the seat body 1. In the production and processing process, the two seat bodies 1 can be processed into the same size. When fixing the two, one of the seat bodies 1 is turned over, so that the two seat bodies 1 can be fixed opposite to each other and surrounded by a four-sided frame structure. At the same time, in this embodiment, in order to facilitate the arrangement of the plug-in protrusion 101 and the slot 102 structure on the first end 103 and the second end 104 of the two seat bodies 1, a thickening portion 105 is arranged on the first end 103 and the second end 104, which effectively improves the structural strength of the end.

[0044] Combination Figure 2 and Figure 3 , each of the three surfaces of the seat body 1 is provided with several groups of liquid cooling groups arranged along the length direction of the seat body 1, the liquid cooling group has a liquid inlet end and a liquid outlet end, and both ends of the seat body 1 are fixedly connected with a steering member, and a steering channel is provided in the steering member, and the liquid outlet end and the liquid inlet end of the adjacent liquid cooling groups in the same seat body 1 are connected through the steering channel. Specifically, in this embodiment, four groups of liquid cooling groups are provided on each seat body 1, wherein one group of liquid cooling groups is provided on the left side and the right side, and two groups of liquid cooling groups are provided on the bottom surface, and each group of liquid cooling groups is provided with at least one cooling channel 3 arranged along the length direction of the seat body 1, and the cooling channel 3 is integrally formed on the outer wall of the seat body 1 by extrusion molding, and the cross section of the cooling channel 3 is one or more combinations of circular, fan-shaped, elliptical or polygonal. In order to facilitate extrusion processing and molding, the cross section of the cooling channel 3 is preferably circular. At the same time, in this embodiment, the number of cooling channels 3 in each group of liquid cooling groups is fifteen, and all cooling channels 3 are arranged in parallel with equal spacing. Of course, this embodiment only provides an example. In other embodiments other than this embodiment, the number of liquid cooling groups on the seat body 1 and the number of cooling channels 3 in each liquid cooling group can be reasonably selected according to the product model.

[0045] like Figure 2As shown, the steering member includes a U-shaped steering ring 4, which is fixedly connected to the end of the seat body 1 by stir friction welding. Figure 2 A plurality of drainage cavities 401 are formed on the inner wall of the steering collar 4. The number of the drainage cavities 401 is the same as the number of the liquid cooling groups on the seat body 1 and they are arranged one by one. A barrier 402 is provided between the two drainage cavities 401 corresponding to the two liquid cooling groups corresponding to the side of the seat body 1 in the steering collar 4 near the rear side of the seat body 1. When the steering collar 4 is welded and fixed to the end of the seat body 1, the aforementioned steering flow channel is surrounded between the drainage cavity 401 and the seat body 1, so that the seat body 1 can be formed as follows. Figure 4 The one-way flow channel is shown by the arrow.

[0046] Combination Figure 1 and Figure 2 In order to facilitate the welding and fixing of the steering collar 4, in this embodiment, mounting bosses 5 are integrally formed at both ends of the seat body 1, and the steering collar 4 is welded on the mounting bosses 5. The positioning and limitation of the mounting bosses 5 make the welding and fixing of the steering collar 4 more convenient, and after welding and fixing, a more stable connection can be formed between the seat body 1 and the mounting bosses 5.

[0047] In actual application of this embodiment, first, the two seat bodies 1 are in an unfixed state, and the power component in the prior art is first hoisted into the U-shaped structure of one of the seat bodies 1, and then the other seat body 1 is hoisted onto the seat body 1 where the power component is placed, so that the plug-in protrusion 101 is inserted into the slot 102, and then the two seat bodies 1 are fixedly connected by stir friction welding, so that the power component can be conveniently installed in the four-sided frame structure surrounded by the two seat bodies 1.

[0048] A liquid cooling device, comprising the above-mentioned spliced ​​four-sided liquid cooling structure, such as Figure 4 As shown, each steering collar 4 can be equipped with a liquid inlet interface 6 and a liquid outlet interface 7, the liquid inlet interface 6 is connected to the liquid inlet end of the liquid cooling group near the first end 103, and the liquid outlet interface 7 is connected to the liquid outlet end of the liquid cooling group at the second end 104, so that the liquid inlet interface 6, all liquid cooling groups and liquid outlet interfaces 7 on the same seat body 1 form a cooling channel with unidirectional flow. Of course, in other embodiments other than this embodiment, the number of liquid inlet interfaces 6 and liquid outlet interfaces 7 set on each seat body 1 can be set according to the number of liquid cooling groups, and the position of the liquid inlet interface 6 and the position of the liquid outlet interface 7 can be set at different positions on the seat body 1 according to actual needs, which will not be repeated here.

[0049] When the electrical components in the four-sided frame generate heat when in use, the cooling medium in the prior art (such as liquid cooling water) is injected into the liquid inlet end of the liquid cooling group at the first end 103 through the liquid inlet interface 6. Under the drainage effect of the drainage cavity 401 in the steering ring 4, the cooling medium flows through all the liquid cooling groups in the seat body 1 in sequence, and finally flows out from the liquid outlet end of the liquid cooling group at the second end 104 to the liquid outlet interface 7. Since the liquid cooling groups are arranged on three sides of the two seat bodies 1, the electrical components can be cooled and dissipated in the up, down, left and right directions, and the heat dissipation is very efficient.

[0050] An electrical equipment comprises the above-mentioned spliced ​​liquid cooling structure or a liquid cooling device, so that the electrical equipment has high-efficiency heat dissipation performance and the installation of electrical components is very convenient.

[0051] Embodiment 2

[0052] The difference between the second embodiment and the first embodiment is that: Figure 5 and Figure 6 As shown, in this embodiment, a blocking portion 106 is integrally formed on the second end 104 of the seat body 1 along the length direction of the seat body 1, and the blocking portion 106 is located at the open end of the slot 102. A groove 1011 that cooperates with the blocking portion 106 is provided on the plug-in protrusion 101. By utilizing the cooperation between the blocking portion 106 and the groove 1011, the two seat bodies 1 can only be inserted and slidably along the length direction of the seat body 1 when connected to each other. The plug-in protrusion 101 is inserted into the slot 102, and the blocking portion 106 and the groove 1011 are slidably matched. , and when the two base bodies 1 slide to the position of forming a four-sided frame, the two base bodies 1 can be welded and fixed by stir friction welding. During the welding process, due to the cooperation between the blocking part 106 and the groove 1011, the two base bodies 1 cannot move along the direction perpendicular to the length of the base body 1, thereby improving the stability and accuracy of the welding and fixing of the two base bodies 1. After the two base bodies 1 are welded and fixed, relying on the locking of the blocking part 106 and the groove 1011, the strength and stability of the connection between the two base bodies 1 are effectively improved.
