Description

Technical Field

[0001] This invention relates to the field of battery heat dissipation devices, and in particular to a dual-cycle battery heat dissipation device and its heat dissipation method. Background Technology

[0002] Currently, the market is flooded with a wide variety of battery-powered electrical products, dazzling consumers. It is well known that once an electrical product is started, a power circuit is formed between its internal battery and the load, and the load operates normally. However, those skilled in the art understand that while the battery supplies power, it also generates heat internally due to the thermal effect of the current. If this heat cannot be dissipated in time, the battery temperature will rise to a certain level. Excessive battery temperature can easily affect the battery's efficiency and lifespan. To address this issue, designers have devised various heat dissipation devices. For example, Chinese utility model patent CN209843896U discloses a heat-dissipating battery, comprising a battery body, a battery cover, a graphene coating, multiple grooves, a mounting slot, and a heat dissipation device. The battery body houses a battery pack and a separator. The graphene coating is applied to the surface of the battery body and the separator. Grooves are located on the surface of the battery body, each groove containing a heat dissipation strip. The mounting slot is located at the bottom of the battery body, and the heat dissipation device is located on the bottom surface of the battery body and electrically connected to it. The heat dissipation device includes a radiator and a thermal switch, with the thermal switch electrically connected to the radiator and matched to the mounting slot. However, this type of device has some shortcomings; its heat dissipation effect is not ideal, potentially causing the battery temperature to be unable to maintain a healthy level. Summary of the Invention

[0003] The purpose of this invention is to provide a dual-cycle battery heat dissipation device and method. This invention effectively dissipates heat from the battery, ensuring that the battery temperature remains at a suitable level.

[0004] The technical solution of the present invention: a dual-cycle battery heat dissipation device includes a cylindrical body, an air inlet cover at the upper end of the cylindrical body with a plurality of air inlets evenly distributed on the air inlet cover, a bottom cover at the lower end of the cylindrical body with an air intake hole; a support body is provided inside the cylindrical body, the support body includes a main body, a circular tube at the upper end of the main body, the circular tube passing through the air inlet cover and extending outward, a plurality of fixing blocks evenly distributed on the main body, the fixing blocks being used to fix the battery, and a connecting cylindrical body at the lower end of the main body.

[0005] In the aforementioned dual-cycle battery heat dissipation device, the main body is olive-shaped.

[0006] In the aforementioned dual-cycle battery heat dissipation device, the bottom cover has an arc-shaped groove, the middle part of the bottom cover has a protrusion, and the air intake hole is located on the protrusion.

[0007] In the aforementioned dual-cycle battery cooling device, there are a total of six air inlets.

[0008] In the aforementioned dual-cycle battery cooling device, the connecting cylinder and the main body have a circular arc transition.

[0009] The specific steps of the aforementioned dual-cycle battery cooling device and its dual-cycle battery cooling method are as follows:

[0010] S1: The battery is mounted on the support body and supported and fixed by the fixing block on the main body. Cooling airflow flows in from the air inlet on the air inlet cover and enters the cylinder. The space in the cylinder is relatively narrow because it is occupied by the olive-shaped main body. After the cooling airflow enters, it can flow quickly to the bottom cover, thereby reducing the pressure loss of the airflow during flow and cooling the battery at the same time, taking away some heat.

[0011] S2: The cooling airflow flows through the arc-shaped transition of the bottom cover, causing the cooling air to circulate and flow, and then flows into the bracket body through the connecting cylinder. At the same time, the cooling airflow drives the air in the air intake. The space inside the main body is relatively large, and the cooling airflow can stay in this space, so that the battery can be cooled to the maximum extent.

[0012] S3: After the cooling air undergoes heat exchange inside the main body, it carries away the heat and is discharged outward from the circular tube, thereby achieving a dual-circulation heat dissipation effect.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This invention features an air inlet cover at the top of the cylinder, with multiple air inlets evenly distributed on the cover. A bottom cover at the bottom of the cylinder has an air intake hole. A support body is located inside the cylinder, comprising a main body with a cylindrical tube at its upper end. The cylindrical tube passes through the air inlet cover and extends outwards. Multiple fixing blocks are evenly distributed on the main body for fixing the battery. The lower end of the main body has a connecting cylinder. The battery is fixed inside the main body of the support body and supported by the fixing blocks. Cooling airflow is introduced through the air inlets on the air inlet cover, flowing into the cylinder to initially cool the battery. The airflow then flows to the bottom cover and enters the support body, simultaneously drawing air from the air intake hole into the support body to cool the battery. The cooling airflow exchanges heat with the battery and finally exits from the cylindrical tube. This circulating channel provides relatively complete cooling of the battery, ensuring its temperature remains healthy and optimal.

[0015] 2. The main body is olive-shaped, which on the one hand compresses the space inside the cylinder, allowing the cooling air that just enters the cylinder to flow quickly and reducing the pressure loss of the airflow; on the other hand, it expands the space inside the support, allowing the cooling airflow to stay here for a period of time to fully cool the battery.

[0016] 3. The bottom cover has an arc groove and a protrusion in the middle. The air intake hole is located on the protrusion. When the cooling airflow reaches the bottom cover, the structure of the arc groove allows the airflow to flow into the support body more quickly, reducing the pressure loss of the airflow.

[0017] 4. The connecting cylinder and the main body are connected by an arc transition, which facilitates the rapid flow of air and reduces pressure loss during airflow. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0022] Example: Dual-cycle battery cooling device, such as Figure 1 and 2As shown, the device includes a cylindrical body 1, with an air inlet cover 2 at the upper end. The air inlet cover 2 has multiple air inlets 3 evenly distributed on it, totaling six, allowing for a greater intake of cooling air. A bottom cover 4 is located at the lower end of the cylindrical body 1, with an air intake hole 5 on it. A support body 6 is located inside the cylindrical body 1, comprising a main body 8. A circular tube 7 is located at the upper end of the main body 8, passing through the air inlet cover 2 and extending outwards. Multiple fixing blocks 9 are evenly distributed on the main body 8 for fixing the battery. A connecting cylinder 10 is located at the lower end of the main body 8, aligned with the air intake hole. The air intake hole's main function is to create an air intake state when cooling airflow enters the support body from the bottom cover, drawing some external air into the support body for better heat dissipation. The connecting cylinder 10 and the main body 8 have a rounded transition, facilitating faster airflow and reducing pressure loss during airflow. The main body 8 is olive-shaped, which on the one hand compresses the space inside the cylinder, allowing the cooling airflow that just enters the cylinder to flow quickly and reducing pressure loss; on the other hand, it expands the space inside the support, allowing the cooling airflow to stay there for a period of time, thus fully cooling the battery. The bottom cover 4 has an arc-shaped groove 11, and a protrusion 12 in the middle of the bottom cover 4. The air intake 5 is located on the protrusion 12. When the cooling airflow flows to the bottom cover, the structure of the arc-shaped groove allows the airflow to flow into the support body relatively quickly, reducing pressure loss.

[0023] The dual-cycle battery cooling method comprises the following steps: S1: The battery is mounted on a support body and supported and fixed by a fixing block on the main body. Cooling airflow flows in from the air inlet on the air inlet cover and enters the cylinder. The space in the cylinder is relatively narrow due to the olive-shaped main body. After entering, the cooling airflow can quickly flow to the bottom cover, thereby reducing the pressure loss during airflow and cooling the battery while removing some heat. S2: The cooling airflow flows through the arc-shaped transition of the bottom cover, causing the cooling air to circulate and flow into the support body through the connecting cylinder. At the same time, the cooling airflow drives the air inflow from the air intake. The space inside the main body is relatively large, allowing the cooling airflow to stay in this space, thereby maximizing the cooling of the battery. S3: After heat exchange in the main body, the cooling air removes heat and is discharged outward from the circular tube, thus achieving a dual-cycle cooling effect.
