Description

Technical Field

[0001] This utility model relates to the field of new energy battery technology, and in particular to a new energy battery tray with heat dissipation performance. Background Technology

[0002] With the rapid development of new energy technologies, new energy batteries have been widely used in electric vehicles, energy storage power stations, and other fields. However, new energy batteries generate a lot of heat during charging and discharging. If the heat cannot be dissipated in time, the battery temperature will rise, which will affect the battery's charging and discharging efficiency and cycle life. In severe cases, it may even cause safety problems such as thermal runaway.

[0003] Existing new energy battery trays mostly serve only as battery holders, with poor heat dissipation performance. Some trays use simple natural convection cooling, which is inefficient and fails to meet the heat dissipation requirements of high-power batteries. Some trays with liquid cooling structures have poorly designed coolant circulation paths, resulting in uneven heat dissipation and failing to effectively reduce battery temperature, thus affecting overall battery performance and safety. Therefore, there is an urgent need to design a new energy battery tray with excellent and uniform heat dissipation performance. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a new energy battery tray with heat dissipation performance.

[0005] This utility model proposes a new energy battery tray with heat dissipation performance, including a tray body. The tray body has a first horizontal tube and a second horizontal tube that are parallel to each other. The first horizontal tube is located above the second horizontal tube. One side wall of the first horizontal tube is connected to a plurality of first straight tubes, and one side wall of the second horizontal tube is connected to a plurality of second straight tubes. The first straight tube and the second straight tube are both located inside the tray body.

[0006] Each of the first straight pipes is perpendicular to the first horizontal pipe, and each of the second straight pipes is perpendicular to the second horizontal pipe. The number of the first straight pipes and the second straight pipes are equal and correspond one-to-one. The corresponding first straight pipes and second straight pipes are parallel to each other.

[0007] The top of the first straight tube is vertically connected to multiple sets of connecting tubes at equal intervals. The top of each set of connecting tubes is connected to a support platform. The support platform is located on the upper side of the tray body to support the battery. A section of the upper part of the connecting tube protrudes from the upper side of the tray body to create a gap between the bottom of the battery and the tray body.

[0008] The support platform has a built-in cavity, and its inner cavity is connected to the first straight pipe through a connecting pipe. The two sides of the support platform are connected to the second straight pipe below it through a return pipe.

[0009] Both ends of the first horizontal pipe and the second horizontal pipe are sealed, and the ends of the first straight pipe and the second straight pipe in each group are sealed. A water inlet pipe is connected to the middle side wall of the first horizontal pipe, and a water outlet pipe is connected to the middle side wall of the second horizontal pipe.

[0010] Preferably, the first straight pipe and the first horizontal pipe are connected by welding to ensure the sealing and stability of the connection.

[0011] Preferably, the connection between the second straight pipe and the second horizontal pipe is integrally cast to ensure smooth flow of coolant.

[0012] Preferably, the support platform is made of aluminum alloy material with good thermal conductivity to improve heat dissipation efficiency.

[0013] Preferably, both the inlet and outlet pipes are provided with sealing threads to facilitate connection with an external coolant circulation system.

[0014] Preferably, the inner walls of the first horizontal pipe, the second horizontal pipe, the first straight pipe, the second straight pipe, the connecting pipe, the support platform, and the return pipe are all treated with anti-corrosion measures to extend their service life.

[0015] Preferably, the pallet body is made of high-strength plastic, which reduces the overall weight while ensuring structural strength.

[0016] The new energy battery tray with heat dissipation performance proposed in this utility model has the following technical effects:

[0017] High-efficiency heat dissipation: This invention utilizes a coolant circulation channel comprised of a first horizontal pipe, a second horizontal pipe, a first straight pipe, a second straight pipe, a connecting pipe, and a return pipe to achieve uniform coolant flow at the bottom of the battery. This allows for rapid removal of heat generated by the battery, resulting in high heat dissipation efficiency. Simultaneously, the unique wave-shaped, honeycomb-like, or densely protruding structure of the contact surface between the support platform and the bottom of the battery significantly increases the contact area, enabling the heat generated by the battery to be transferred more quickly and fully to the coolant within the support platform's inner cavity. Furthermore, the bottom heat dissipation space created by the support platform suspending the battery promotes natural air convection, which, combined with the coolant circulation, further enhances heat dissipation efficiency.

[0018] Uniform heat dissipation: Multiple sets of parallel and corresponding first and second straight pipes, as well as connecting pipes and support platforms set at equal intervals, enable the coolant to contact the bottom of the battery evenly, ensuring uniform heat dissipation in all parts of the battery and avoiding local overheating.

[0019] Stable structure: The first straight pipe and the first horizontal pipe are connected by welding, and the second straight pipe and the second horizontal pipe are integrally cast, which ensures the structural stability and sealing of the entire coolant circulation system and ensures the reliability of coolant circulation.

[0020] Lightweight design: The main body of the pallet is made of high-strength plastic, and the support platform is made of aluminum alloy. While meeting the requirements of structural strength and heat dissipation performance, the weight of the pallet is effectively reduced, which is conducive to the lightweight design of new energy equipment.

[0021] Long lifespan: Corrosion protection treatment is applied to the inner walls of all pipes and support platforms to effectively resist the corrosion of coolant, extend the service life of the battery tray, and reduce maintenance costs.

[0022] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] like Figures 1-3 The diagram shows a new energy battery tray with heat dissipation performance, comprising a tray body 3. The tray body 3 has a first horizontal tube 1 and a second horizontal tube 2 that are parallel to each other, with the first horizontal tube 1 located above the second horizontal tube 2. One side wall of the first horizontal tube 1 is connected to multiple sets of first straight tubes 101, and one side wall of the second horizontal tube 2 is connected to multiple sets of second straight tubes 201. Both the first straight tubes 101 and the second straight tubes 201 are located inside the tray body 3.

[0029] Each first straight pipe 101 is perpendicular to the first horizontal pipe 1, and each second straight pipe 201 is perpendicular to the second horizontal pipe 2. The number of first straight pipes 101 and second straight pipes 201 is equal and they correspond one-to-one. The corresponding first straight pipes 101 and second straight pipes 201 are parallel to each other.

[0030] The top of the first straight pipe 101 is vertically connected to multiple sets of connecting pipes 102 at equal intervals. The top of each set of connecting pipes 102 is connected to a support platform 103, which is located on the upper side of the tray body 3 and is used to support the battery. A section of the upper part of the connecting pipe 102 protrudes from the upper side of the tray body 3 to create a gap between the bottom of the battery and the tray body 3, thus suspending the battery and creating a heat dissipation space at the bottom of the battery.

[0031] The support platform 103, used to support the bottom of the battery, has a surface that is wavy, honeycomb-shaped, or densely covered with protrusions to increase the contact area with the bottom of the battery. The support platform 103 has a built-in cavity, which is connected to the first straight pipe 101 through a connecting pipe 102. The two sides of the support platform 103 are connected to the second straight pipe 201 below it through a return pipe 202. Both ends of the first horizontal pipe 1 and the second horizontal pipe 2 are sealed, and the ends of each set of first straight pipe 101 and second straight pipe 201 are sealed. A water inlet pipe 104 is connected to the middle side wall of the first horizontal pipe 1, and a water outlet pipe 203 is connected to the middle side wall of the second horizontal pipe 2.

[0032] Furthermore, the first straight pipe 101 and the first horizontal pipe 1 are connected by welding to ensure the sealing and stability of the connection and prevent coolant leakage.

[0033] The connection between the second straight pipe 201 and the second horizontal pipe 2 is integrally cast, which ensures smooth flow of coolant, reduces flow resistance, and improves coolant circulation efficiency.

[0034] The support platform 103 is made of aluminum alloy with good thermal conductivity, which can quickly transfer the heat generated by the battery to the coolant and improve heat dissipation efficiency. At the same time, the bottom heat dissipation space formed by the battery suspended on the support platform 103 can assist natural air convection, which works in conjunction with the cooling fluid circulation inside the support platform 103 to further enhance the heat dissipation effect.

[0035] Both the inlet pipe 104 and the outlet pipe 203 are equipped with sealing threads to facilitate connection with an external coolant circulation system and achieve stable coolant circulation.

[0036] The inner walls of the first horizontal pipe 1, the second horizontal pipe 2, the first straight pipe 101, the second straight pipe 201, the connecting pipe 102, the support platform 103, and the return pipe 202 are all treated with anti-corrosion measures, which can effectively prevent the coolant from corroding the inner walls of the pipes and extend the service life of the tray.

[0037] The pallet body 3 is made of high-strength plastic, which reduces the overall weight while ensuring structural strength, thereby reducing the load on new energy equipment and improving energy utilization efficiency.

[0038] The coolant is connected to an external coolant circulation system via an inlet pipe 104 and an outlet pipe 203. Coolant flows from the inlet pipe 104 into the first horizontal pipe 1, then branches into the first straight pipes 101, and enters the cavity of the support platform 103 through the connecting pipe 102. Due to the special structural design of the support platform 103 with its large contact area with the bottom of the battery, it can efficiently absorb heat from the battery. After carrying away the heat from the bottom of the battery, the coolant flows into the second straight pipe 201 through the return pipe 202, and finally flows out from the outlet pipe 203, completing the coolant circulation and heat dissipation process. Simultaneously, the elevated space at the bottom of the battery allows for natural airflow, further helping to remove some heat. This, combined with the coolant circulation, achieves efficient and uniform heat dissipation for the new energy battery.
