Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation plates, and particularly relates to a heat dissipation plate for a new energy lithium battery. Background Art

[0002] A heat dissipation plate is a product used for heat dissipation, usually made of metal or heat-conducting plastic, such as aluminum or copper. Its working principle is to utilize the good heat-conducting property of the heat dissipation plate itself to quickly transfer the heat inside the device to the heat dissipation plate, and use the large-area structure of the heat dissipation plate to improve the heat dissipation efficiency. The main heat transfer methods of the heat dissipation plate include the heat conduction method, that is, the material of the heat dissipation plate itself has good heat conductivity and can quickly transfer the heat inside the substance to the surface of the heat dissipation plate.

[0003] In the traditional technology, the patent with the publication number of CN213459875U discloses a lithium battery heat dissipation plate, which includes a heat dissipation upper plate, a heat dissipation lower plate, and a heat dissipation cylinder clamped and fixed in the middle for placing the lithium battery. The heat dissipation upper plate and the heat dissipation lower plate are respectively integrally connected with a fixed upper ring and a fixed lower ring that are snapped and fixed to the heat dissipation cylinder. The heat dissipation cylinder is in a circular ring structure with both ends open and a cavity, and a number of heat dissipation holes communicating with the inside are distributed on the outside. The heat dissipation holes are located between the fixed upper ring and the fixed lower ring and are horizontally aligned. A number of raised fixing blocks are distributed on the outer edge of the open ends of the heat dissipation cylinder. The fixed upper ring and the fixed lower ring are both provided with a number of fixing grooves that match and insert the fixing blocks. The heat dissipation upper plate and the heat dissipation lower plate are both provided with a number of placement holes communicating with the inner cavity of the heat dissipation cylinder. An insulating upper plate with an equal area is laid on the surface of the heat dissipation upper plate, and an insulating lower plate with an equal area is laid on the surface of the heat dissipation lower plate. The heat dissipation cylinder with a heat dissipation function is adopted to improve the air circulation and the heat dissipation effect.

[0004] However, there are some problems in the traditional technology: the above traditional device uses the method of opening heat dissipation holes in the installation bracket of the lithium battery to dissipate heat from the lithium battery. However, in actual use, when several lithium batteries dissipate heat simultaneously, hot air will accumulate in the gaps of the installation bracket, and it is very difficult to dissipate heat from the whole by relying on natural wind, resulting in serious heating of the lithium battery after long-term use. Therefore, we propose a heat dissipation plate for a new energy lithium battery. Summary of the Invention

[0035] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with the accompanying drawings.

[0036] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0037] If Figures 1 to 6 As shown, a new energy lithium battery heat sink comprises an air inlet pipe 1, an air outlet pipe 2 and a plurality of heat sinks 5 for placing lithium batteries;

[0038] The air inlet of the air inlet pipe 1 is connected to the air source, and the air inlet pipe 1 is provided with a plurality of air inlet outlets, and the corresponding air inlet pipe 1 is provided with a plurality of air inlet branches; the air outlet pipe 2 is provided with a plurality of air outlet inlets, and the corresponding air outlet pipe 2 is provided with a plurality of air outlet branches, and the air outlet of the air outlet pipe 2 is communicated with the outside; the number of the air inlet branches and the number of the air outlet branches are the same as the number of the heat sink 5;

[0039] The heat sink 5 comprises an upper cover 501, a support tube 502 and a support base 503 which are sequentially connected from top to bottom;

[0040] The side of the upper cover 501 is provided with an air inlet connected to the outlet of the air inlet pipe 1; the side of the support seat 503 is provided with an air outlet connected to the air inlet. That is, the side of the upper cover 501 is connected and communicated with the corresponding air inlet branch pipe; the side of the support seat 503 is connected and communicated with the corresponding air outlet branch pipe.

[0041] The above-mentioned new energy lithium battery heat sink is connected to an external air source through an air inlet pipe 1 to generate a stable airflow. This airflow enters the heat sink 5 through the air inlet. When the airflow flows inside the heat sink 5, it passes through the annular gas flow channel on the support tube 502. This flow channel design allows the airflow to flow evenly through the surface of the lithium battery and take away the heat generated by the lithium battery.

[0042] It comprises four heat sinks 5, which are staggeredly plugged and installed on the left side or / and right side of the air inlet pipe 1 and the air outlet pipe 2.​

[0043] Four air inlet outlets are provided on the left side or / and the right side of the intake pipe 1, and each air inlet outlet is connected with an intake pipe interface 11, and the four intake pipe interfaces 11 are respectively connected with the air inlet;

[0044] Four air outlet inlets are provided on the left side or / and the right side of the outlet pipe 2, and each air outlet inlet is connected with an outlet pipe interface 21, and the four outlet pipe interfaces 21 are respectively connected with the air outlet.

[0045] Specifically, four intake branch pipes are provided on the left side or / and the right side of the intake pipe 1, and the intake branch pipes are connected to the corresponding upper covers 501;

[0046] Four outlet branch pipes are provided on the left side or / and the right side of the outlet pipe 2, and the outlet branch pipes are connected to the corresponding support seats 503.

[0047] Since the air flow is forced, its heat dissipation effect is much better than that of natural wind heat dissipation. After the lithium battery is cooled, the air flow with increased temperature, that is, the hot air, is discharged through the air outlet on one side of the support seat 503 and guided to the external environment by the outlet pipe 2. In the system composed of multiple heat dissipation seats 5, each heat dissipation seat 5 can independently perform air-cooled heat dissipation. At the same time, since the intake pipe 1 and the outlet pipe 2 are connected by the support rod 3, the whole system forms a closed air flow cycle, thereby improving the heat dissipation efficiency. Multiple heat dissipation seats 5 can be conveniently combined together to form a large-scale heat dissipation system to meet the heat dissipation requirements of different numbers of lithium batteries.

[0048] By adjusting the power of the gas source and the number of heat dissipation seats 5, the heat dissipation effect can be flexibly controlled to meet the requirements of different working environments and lithium battery types.

[0049] Three partition plates 4 are fixedly connected inside the outlet pipe 2, and the three partition plates 4 divide the interior of the outlet pipe 2 into four air outlet channels 9, and the four air outlet channels 9 respectively lead to four air outlet outlets, that is, the four air outlet channels 9 respectively lead to four outlet branch pipes;

[0050] Flow guide plates 10 are respectively fixedly installed at the four air outlet outlets, and flow guide grooves connected to the four outlet pipe interfaces 21 are respectively formed in the four flow guide plates 10. That is, flow guide plates 10 are respectively fixedly installed at the four outlet branch pipes, and flow guide grooves connected to the pipe orifices of the four outlet branch pipes are respectively formed in the four flow guide plates 10, and the flow guide grooves are communicated with the corresponding air outlet channels 9.

[0051] Regarding the design of the air outlet pipe 2, to ensure that the heat dissipation effect of each heat dissipation seat 5 can reach the best state. Inside the air outlet pipe 2, three partition plates 4 are fixedly connected, and these three partition plates 4 divide the hollow part of the air outlet pipe 2 into four independent air flow channels 9. Each air flow channel 9 ensures that the hot air in the heat dissipation seat 5 can be efficiently exported, while avoiding interference between each other. To further improve the heat dissipation effect, we fixedly installed flow guide plates 10 at the four air intake outlets of the air outlet pipe 2. These four flow guide plates 10 not only enhance the structural stability, but more importantly, each is provided with flow guide grooves that are precisely corresponding to the four channels. The design of these flow guide grooves enables the hot air to flow out smoothly along a specific path without backflow or turbulent flow phenomena.

[0052] Compared with the traditional heat dissipation device that uses one air duct as the output, this four-channel design has significant advantages. First, it avoids the backflow problem caused by the impact of hot air during the operation of the air pump, thus ensuring the stability of the heat dissipation effect. Finally, this design can also reduce noise and vibration, improving the stability and reliability of the entire heat dissipation system.

[0053] An insertion plate 6 is connected to the air intake inlet of the air intake pipe 1;

[0054] The insertion plate 6 is provided with an air intake seat 8 for connecting to the air source, and the air intake seat 8 is communicated with the air intake pipe 1.

[0055] The upper side surface of the support seat 503 is connected with a negative conductive sheet 506; the lower side surface of the upper cover 501 is connected with a positive conductive member 504.

[0056] The positive conductive member 504 includes a limit tube 5041, a positive conductive sheet 5042 and a spring 5043; the limit tube 5041 is fixedly connected to the lower side surface of the upper cover 501;

[0057] The positive conductive sheet 5042 is arranged at the lower end of the limit tube 5041, and the positive conductive sheet 5042 and the limit tube 5041 are elastically connected by a spring 5043. Specifically, the positive conductive sheet 5042 is slidably embedded in the limit tube 5041, and the positive conductive sheet 5042 slides up and down in the limit tube 5041. A spring 5043 is arranged above the positive conductive sheet 5042 inside the limit tube 5041. This design enables the positive conductive sheet 5042 to be finely adjusted according to the actual position of the lithium battery, ensuring the tightness of contact and the reliability of conduction.

[0058] The side wall of the insertion plate 6 is also connected with a contact electrode sheet 7, and the contact electrode sheet 7 is electrically connected to the positive conductive sheet 5042 and the negative conductive sheet 506 respectively.

[0059] In the design of the heat dissipation plate, we considered the integration of power supply and heat dissipation of the lithium battery. At the upper part of the support base 503, the negative electrode conductive sheet 506 is firmly connected, ensuring a stable connection between the negative electrode of the lithium battery and the heat dissipation plate. At the lower part of the upper cover 501, an elastic positive electrode conductive part 504 is provided, which not only ensures stable contact with the positive electrode of the lithium battery but also can adapt to lithium batteries of different sizes to a certain extent.

[0060] In addition, this layout not only improves the heat dissipation efficiency but also makes the entire heat dissipation system more compact and stable. The input end of the intake pipe 1 is connected to the plug board 6, and an intake seat 8 is fixed on one side of the plug board 6 for connecting an air pump (air source) to provide a continuous airflow for the heat dissipation system. A contact electrode sheet 7 is also provided on one side of the plug board 6. This innovative design enables the lithium batteries in multiple heat dissipation seats 5 to be powered or charged simultaneously. The contact electrode sheet 7 matches the positive and negative electrode conductive sheets 506 of the lithium battery. When the lithium battery is placed in the heat dissipation seat 5, the contact electrode sheet 7 can be in close contact with the conductive sheet of the lithium battery, thereby realizing the conduction of current. This design not only simplifies the power supply or charging process of the lithium battery but also improves the safety and reliability of the entire system. The upper cover 501 is electrically connected to the support base 503 when plugging into the support cylinder 502.

[0061] A plug rod 505 is fixedly connected to the lower part of the upper cover 501, and a slot corresponding to the plug rod 505 is opened at the upper part of the support cylinder 502, and the plug rod 505 is movably inserted into the slot of the support cylinder 502.

[0062] During use, a stable airflow is generated by connecting an external air source through the intake pipe 1. This airflow enters the interior of the heat dissipation seat 5 through the air inlet. When the airflow flows inside the heat dissipation seat 5, it will pass through the annular gas flow channel on the support cylinder 502. This flow channel design enables the airflow to evenly flow through the surface of the lithium battery, taking away the heat generated by the lithium battery. Since the airflow is forced, its heat dissipation effect is much better than natural wind heat dissipation. After the lithium battery is cooled, the airflow with increased temperature (i.e., hot air) is discharged through the air outlet on one side of the support base 503 and guided to the external environment by the outlet pipe 2. In a system composed of multiple heat dissipation seats 5, each heat dissipation seat 5 can independently perform air-cooled heat dissipation. At the same time, since the intake pipe 1 and the outlet pipe 2 are connected by the support rod 3, the entire system forms a closed airflow cycle, thereby improving the heat dissipation efficiency. Multiple heat dissipation seats 5 can be conveniently combined together to form a large-scale heat dissipation system to meet the heat dissipation requirements of different numbers of lithium batteries.
