[0002] With the rapid development of new energy electric vehicles, the safety performance of batteries has received more and more attention. At present, the battery thermal management system mainly uses water cooling with higher heat transfer efficiency and more uniform temperature control. As a component of the thermal management system of power vehicle batteries, the harmonica-type liquid cooling plate has the advantages of high space utilization and low manufacturing and design costs, and has been widely used. In the conventional harmonica-type liquid cooling plate thermal management system, the current collector is a key component. After being matched with the harmonica-type liquid cooling plate, it is connected by high-temperature brazing, so that the cooling medium can converge and divert in the harmonica tube.

[0003] At present, the processing technology of current collectors is usually aluminum extrusion processing and die-casting processing. The main disadvantages are high cost of aluminum profiles, low processing efficiency, short mold life, and high environmental pollution. Especially for products with slightly complex structures, secondary clamping is required in the CNC stage after aluminum extrusion pre-forming, which means that the accuracy cannot be guaranteed during the processing, so the defect rate is high. As we all know, cost reduction and environmental protection are problems that the manufacturing industry has had to face for a long time, and they are also important indicators of the industry's competitiveness. With the gradual application of economical and efficient injection molded parts in the field of new energy vehicles, there is an urgent need for a special current collector structure for harmonica-style liquid cooling plates formed by injection molding.

[0030] References throughout the specification to "one embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of "in one embodiment" or "in an embodiment" in various places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any manner in one or more embodiments.

[0031] As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. It should be noted that the term "or" is generally employed in its sense including "and / or" unless the context clearly dictates otherwise.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] See also Figure 1-5 As shown, a special collector structure for a harmonica-type liquid cooling plate formed by an injection molding process is mainly composed of an internally hollow assembly functional area plastic profile 1, a plastic water inlet pipe 2 and a plastic water outlet pipe 3 formed in one piece by an injection molding process.

[0034] The upper and lower side walls of the plastic profile 1 of the assembly functional area are respectively provided with a water inlet hole and a water outlet hole. The positions of the water inlet hole and the water outlet hole correspond to each other and are concentric. The sizes of the water inlet hole and the water outlet hole are also the same.

[0035] The plastic water inlet pipe 2 and the plastic water outlet pipe 3 are respectively integrally formed by injection molding and arranged outside the water inlet hole and the water outlet hole. The plastic water inlet pipe 2 and the plastic water outlet pipe 3 have the same size. The plastic water inlet pipe 2 is connected to the cavity in the plastic profile 1 of the assembly functional area through the water inlet hole, and the plastic water outlet pipe 3 is connected to the cavity in the plastic profile 1 of the assembly functional area through the water outlet hole.

[0037] In order to facilitate assembly and fixation with the corresponding water pipe, a plastic water inlet pipe outer convex ring 4 which is injection molded integrally with the plastic water inlet pipe 2 is provided on the outer wall of the pipe mouth of the plastic water inlet pipe 2, and a plastic water outlet pipe outer convex ring 5 which is injection molded integrally with the plastic water outlet pipe 3 is provided on the outer wall of the pipe mouth of the plastic water outlet pipe 3.

[0038] As a preferred embodiment of the utility model, the outer walls of the plastic water inlet pipe outer convex ring 4 and the plastic water outlet pipe outer convex ring 5 are both designed with conical inclined surfaces. Specifically, the outer shapes of the plastic water inlet pipe outer convex ring 4 and the plastic water outlet pipe outer convex ring 5 are both truncated cone-shaped, that is, the outer diameter of the convex ring gradually increases from close to the pipe mouth to far away from the pipe mouth. This C2 chamfer design not only forms a guiding cone surface on the pipe mouths of the plastic water inlet pipe 2 and the plastic water outlet pipe 3, so that the corresponding water pipe can be smoothly installed on the plastic water inlet pipe 2 and the plastic water outlet pipe 3, avoiding the problem of appearance damage caused by assembly, but also enables the plastic water inlet pipe 2 and the plastic water outlet pipe 3 to form an interference fit with the corresponding water pipe to avoid the water pipe from falling off.

[0039] The front and rear side walls of the assembly functional area plastic profile 1 are respectively provided with assembly slots 6 for connecting with the harmonica-type liquid cooling plate. The assembly functional area plastic profile 1 can be an annular plate with an elliptical cross section, the two planes of the annular plate serve as the upper and lower side walls of the assembly functional area plastic profile 1, the two arc surfaces of the annular plate serve as the left and right side walls of the assembly functional area plastic profile 1, the two elliptical through holes of the annular plate serve as the front and rear assembly slots 6 of the assembly functional area plastic profile 1, and the assembly slots 6 are connected and fixed to the harmonica-type liquid cooling plate by gluing. The assembly slot 6 can adopt a step groove design with a depth of 5 mm, and at the same time play the role of assembly limit, so that the overall size meets the assembly requirements and improves the product precision.

[0040] As a preferred embodiment of the utility model, the dimensions of the plastic profile of the assembly functional area are 97 mm in length, 35 mm in width, and 45 mm in height.

[0041] As a preferred embodiment of the utility model, the plastic profile 1 of the assembly functional area, the plastic water inlet pipe 2, the plastic water outlet pipe 3, the plastic water inlet pipe outer convex ring 4 and the plastic water outlet pipe outer convex ring 5 are all made of PA66 plastic material (containing 15-30% glass fiber) and are integrally formed by injection molding.

[0042] Compared with the current collector structure made by traditional production methods such as aluminum extrusion molding + machining process or die casting molding + machining process, the utility model can not only achieve rapid production, thereby meeting the market's large demand for products, but also reduce labor costs and material waste, reduce corporate production costs, thereby improving the market competitiveness of products, and at the same time it is more environmentally friendly and can reduce pollution to the environment. Cost reduction and environmental protection are both issues that the manufacturing industry has long had to face, and are also important indicators of industry competitiveness. With the continuous growth of market demand for injection molded parts in the field of new energy vehicles, the harmonica-style liquid cooling plate special current collector structure formed by injection molding provided by the utility model has broad application prospects in the field of new energy vehicles and has a decisive competitiveness in the new energy market.
