Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of liquid cooling plate equipment, specifically to a box structure for an aluminum extruded PCS liquid cooling plate. Background Technology
[0002] CS liquid-cooled plate enclosures are key components in energy storage systems for achieving efficient heat dissipation and ensuring stable equipment operation. Through effective heat dissipation, liquid-cooled plate enclosures can reduce the operating temperature of batteries and other electrical components, reduce the impact of thermal stress on the equipment, and thus extend the service life of the equipment.
[0003] For example, the utility model patent disclosed in publication number CN213988999U discloses an ultra-thin battery box with an integrated liquid cooling plate. The liquid cooling plate includes a liquid cooling plate and front, rear, left, and right side plates welded and fixed to the four edges of the liquid cooling plate. The liquid cooling plate includes a base plate, interfaces, a front plug plate, and a rear plug plate. The base plate has a flow channel for coolant circulation, with interfaces at the inlet and outlet of the flow channel. The left and right side plates are respectively fixed to the left and right sides of the base plate by friction stir welding, and the front and rear plug plates are respectively fixed to the front and rear side plates by friction stir welding. The front and rear plug plates are welded and fixed to the front and rear side plates, respectively. In this utility model, all four sides of the base plate are welded by friction stir welding, and the welding is continuous with no stress concentration points in the weld, reducing the risk of the base plate being welded through. It has high strength and good reliability, achieving a high degree of integration between the liquid cooling plate and the battery box, effectively reducing the weight and height of the battery pack, and contributing to the realization of ultra-thin battery design. Although the aforementioned liquid cooling plate has certain integrated functions, when the liquid cooling plate is used to dissipate heat from heat sources such as batteries, its efficiency in dissipating heat is insufficient when the surface of the heat source is uneven. At the same time, the heat exchange efficiency of the liquid cooling plate flow channel is also insufficient, which reduces the stability of the equipment in dissipating heat from the heat source. Therefore, there is an urgent need for an aluminum extruded PCS liquid cooling plate housing structure to solve the above-mentioned problems. Utility Model Content
[0004] The purpose of this utility model is to provide an aluminum extruded PCS liquid cooling plate housing structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a liquid-cooled aluminum extruded PCS box structure, including a heat exchange device, wherein a sealing cover plate for sealing is fixedly provided on the upper end face of the heat exchange device. A heat-conducting device is provided, and multiple sets of the heat-conducting device are fixedly arranged at equal intervals on the inner end face of the heat exchange device. The heat-conducting device is used for heat conduction and heat dissipation. A heat dissipation guide plate is fixedly disposed on the lower end face of the heat exchange device, and sealing guide holes are provided at equal intervals on the inner end face of the heat dissipation guide plate.
[0006] Preferably, the heat exchange device includes a liquid-cooled plate shell, with coolant conduits symmetrically arranged at the center of the side end face of the liquid-cooled plate shell, and heat exchange cylinders equidistantly arranged at the inner end face of the liquid-cooled plate shell.
[0007] Preferably, the heat-conducting device includes a heat exchange guide shaft, a positioning slide shaft is slidably engaged at the center of the lower end face of the heat exchange guide shaft, and a heat exchange head is fixedly disposed at the center of the lower end face of the positioning slide shaft. The bottom of the heat exchange guide shaft and the upper part of the heat exchange head are fixedly connected by a return spring.
[0008] Preferably, the upper end face of the liquid cooling plate housing is sealed and fixedly connected to the sealing cover plate, which can effectively improve the sealing stability of the liquid cooling plate housing body.
[0009] Preferably, the heat exchange guide shaft is fixedly connected to the inside of the liquid cooling plate housing through the heat exchange cylinder. After the heat exchange head introduces heat energy, the heat exchange guide shaft can introduce heat energy into the inside of the heat exchange cylinder, thereby improving the heat dissipation efficiency of the battery.
[0010] Preferably, the heat exchange head is connected to the heat dissipation guide plate in a sealed sliding connection through the sealing guide hole. The sealing guide hole can provide sufficient guiding space for the heat exchange head, thereby increasing the height of the heat exchange head's displacement inside the heat dissipation guide plate and facilitating subsequent connection to uneven parts of the battery.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a heat exchange device and a heat conduction device, this utility model can initially connect with the flat parts of the battery when dissipating heat from the battery. At the same time, under the guidance of the return spring and the alignment slide shaft, multiple heat exchange heads can connect with the uneven parts of the battery. The dual heat dissipation connection structure can effectively increase the contact area between the liquid cooling plate shell and the outer surface of the battery. Meanwhile, the multiple heat exchange cylinders also improve the heat exchange efficiency inside the liquid cooling plate shell, thereby simultaneously improving the efficiency and stability of the equipment in dissipating heat from the battery.

Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-4 One embodiment of this utility model provides: an aluminum extruded PCS liquid-cooled plate housing structure, including a heat exchange device 2, with a sealing cover plate 1 for sealing fixedly disposed on the upper end face of the heat exchange device 2. The heat conduction device 3 is provided in multiple sets, and the multiple sets of heat conduction devices 3 are fixedly arranged at equal intervals on the inner end face of the heat exchange device 2. The heat conduction device 3 is used for heat conduction and heat dissipation. The heat dissipation guide plate 4 is fixedly installed on the lower end face of the heat exchange device 2, and sealing guide holes 5 are equidistantly opened on the inner end face of the heat dissipation guide plate 4.
[0016] like Figure 3 The heat exchange device 2 includes a liquid-cooled plate shell 21, with coolant conduits 23 symmetrically arranged at the center of the side end face of the liquid-cooled plate shell 21, and heat exchange cylinders 22 equidistantly arranged at the inner end face of the liquid-cooled plate shell 21.
[0017] like Figure 4 The heat conduction device 3 includes a heat exchange guide shaft 31, a positioning slide shaft 34 is slidably engaged at the center of the lower end face of the heat exchange guide shaft 31, and a heat exchange head 33 is fixedly installed at the center of the lower end face of the positioning slide shaft 34. The bottom of the heat exchange guide shaft 31 and the upper part of the heat exchange head 33 are fixedly connected by a return spring 32.
[0018] like Figure 1 The upper end face of the liquid cooling plate housing 21 is sealed and fixedly connected to the sealing cover plate 1, which can effectively improve the sealing stability of the liquid cooling plate housing 21 body.
[0019] like Figure 3 ,and Figure 4 The heat exchange guide shaft 31 is fixedly connected to the inside of the liquid cooling plate housing 21 through the heat exchange cylinder 22. After the heat exchange head 33 introduces heat energy, the heat exchange guide shaft 31 can introduce heat energy into the inside of the heat exchange cylinder 22, thereby improving the heat dissipation efficiency of the battery.
[0020] like Figure 1 The heat exchange head 33 is connected to the heat dissipation guide plate 4 in a sealed sliding connection through the sealing guide hole 5. The sealing guide hole 5 can provide sufficient guiding space for the heat exchange head 33, thereby increasing the height of the displacement of the heat exchange head 33 inside the heat dissipation guide plate 4, which facilitates the subsequent connection to uneven parts of the battery.
[0021] Working principle: When cooling the battery, the operator can position the liquid cooling plate housing 21 into the rivet hole on the side of the battery using rivets, thus completing the docking between the liquid cooling plate housing 21 and the battery. At the same time, the multiple heat exchange heads 33 at the bottom of the liquid cooling plate housing 21 can fully fit with the upper part of the battery. As the alignment heat dissipation guide plate 4 fits with the upper part of the battery, the heat exchange heads 33, under the elastic guidance of the return spring 32, can fully fit with the uneven parts of the battery, thereby increasing the heat dissipation area with the battery. During heat dissipation, the heat dissipation guide plate 4 first absorbs heat energy and then guides it into the liquid cooling plate housing 21. At the same time, the multiple heat exchange heads 33 can further absorb heat energy on the surface of the battery and then guide it into the heat exchange cylinder 22 through the heat exchange guide shaft 31, thus completing the dual heat conduction operation. Subsequently, the external coolant connection pipe can circulate the coolant into the liquid cooling plate housing 21 through the coolant conduit 23 to complete the heat dissipation operation.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
