Description

Technical Field

[0001] The utility model belongs to the field of new energy automobile parts, and specifically discloses an aluminum alloy fin type radiator used for new energy automobile batteries. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and new vehicle power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

[0003] The power battery in an electric vehicle is the heart of the electric vehicle. It releases heat during charging and discharging. There are three mainstream heat dissipation methods for power batteries:

[0004] 1. Introduction to air cooling:

[0005] 1. Install a cooling fan at one end of the power battery pack and leave ventilation holes at the other end to accelerate the flow of air between the gaps of the battery cells and remove the high heat generated by the battery cells when they are working;

[0006] 2. Add thermal conductive silicone sheets to the top and bottom of the electrode, so that the heat that is not easy to dissipate at both ends can be conducted to the metal shell through the thermal conductive silicone pad to dissipate heat. At the same time, the high electrical insulation and anti-puncture performance of the thermal conductive silicone sheet have a good protective effect on the power battery pack.

[0007] 2. Introduction of liquid cooling method:

[0008] 1. The heat of the battery cell is transferred to the liquid cooling tube through the thermally conductive silicone sheet. The cold liquid circulates freely based on the principle of thermal expansion and contraction to take away the heat, making the temperature of the entire power battery pack uniform. The strong specific heat capacity of the cold liquid absorbs the heat generated by the battery cell when it is working, making the entire battery pack operate within a reliable temperature range.

[0009] 2. The good high rebound toughness and insulation performance of the thermal conductive silicone sheet can avoid the vibration and friction damage between the battery cells and the short circuit hidden danger between the battery cells. It is a good auxiliary material for water cooling solutions.

[0010] 3. Introduction to natural convection cooling method:

[0011] 1. Some power battery packs have large spaces and good contact with the air. The exposed parts can exchange heat naturally through the air, while the bottom parts that cannot exchange heat naturally are cooled through the radiator. The thermally conductive silicone sheet fills the gap between the radiator and the power battery pack for heat conduction, shock absorption, and insulation.

[0012] Therefore, the radiator is a very important component in the battery of new energy vehicles, and there is still room for optimization in the current radiator structure and heat dissipation performance. Utility Model Content

[0013] In response to the above problems, the utility model discloses an aluminum alloy fin-type radiator for new energy vehicle batteries, which uses a symmetrical four-heat dissipation array and forms an X-shaped heat dissipation duct at the junction of the arrays, thereby reducing material usage and improving air flow efficiency.

[0014] The technical solution of the utility model is as follows:

[0015] An aluminum alloy fin-type radiator for new energy vehicle batteries includes a first base, a second base, a first heat sink array, a second heat sink array, a third heat sink array, a fourth heat sink array, and an X-shaped heat dissipation duct; the first base is a regular hexagonal base with a certain thickness; the second base is a cylindrical base, and one side of the second base is fixed to the first base; the other side of the second base is equipped with evenly distributed first heat sink array, second heat sink array, third heat sink array, and fourth heat sink array; each array is composed of a number of heat sinks arranged parallel to each other, and the heat sinks are vertically spaced on the second base; the first heat sink array and the third heat sink array are symmetrically arranged; the second heat sink array and the fourth heat sink array are symmetrically arranged; an X-shaped heat dissipation duct is formed between the four arrays; the width of the X-shaped heat dissipation duct is greater than the width between every two heat sinks in the same array. Setting an X-shaped heat dissipation duct can reduce material usage while improving air flow efficiency and improving the heat dissipation effect of the entire radiator.

[0016] Furthermore, in the above aluminum alloy finned heat sink for new energy vehicle batteries, in each array, the width of the heat sink increases symmetrically from both sides of the array to the middle, and an X-shaped heat dissipation air duct is finally formed between the four arrays. Optimizing the air duct can further improve the heat dissipation efficiency.

[0017] Furthermore, in the above-mentioned aluminum alloy fin-type radiator for new energy vehicle batteries, the intervals between the heat sinks are equal in each array; one side of the heat sink is connected to the circumference of the second base array, and the other side of the heat sink forms the edge of an X-shaped heat dissipation duct.

[0018] Furthermore, in the above-mentioned aluminum alloy fin-type heat sink for new energy vehicle batteries, the diameter of the second base is slightly smaller than the inner diameter of the first base.

[0019] Furthermore, in the above-mentioned aluminum alloy finned heat sink for new energy vehicle batteries, second threaded through holes are evenly arranged at the four corners of the second base. The second threaded through holes are arranged to facilitate fixing the second base on the first base.

[0020] Furthermore, in the above-mentioned aluminum alloy finned heat sink for new energy vehicle batteries, the second threaded through hole is installed with a screw, and the second base can be installed on the first base, so that it is convenient to disassemble and replace the heat sink without replacing the first base.

[0021] Furthermore, in the aluminum alloy finned heat sink for new energy vehicle batteries, the second threaded through hole is provided with a fan mounting hole, which is convenient for installing a fan on the top of the heat sink.

[0022] Furthermore, in the above-mentioned aluminum alloy finned heat sink for new energy vehicle batteries, first threaded through holes are evenly arranged near the six corners of the first base. The first threaded through holes are arranged to facilitate the installation of the first base on the battery pack that needs heat dissipation.

[0023] Furthermore, in the above-mentioned aluminum alloy fin type heat sink for new energy vehicle batteries, the lower end of the heat sink is embedded in the second base. The lower end is embedded in the second base, which can better conduct heat from the second base.

[0024] Furthermore, in the above-mentioned aluminum alloy fin-type radiator for new energy vehicle batteries, the thickness of the first base is 20.5 mm, the thickness of the second base is 7.5 mm, the height of the heat sink exposed from the second base is 68 mm; the side length of the first base is 117 mm.

[0025] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0026] The utility model discloses an aluminum alloy fin radiator for new energy vehicle batteries, which has a simple structure and beautiful appearance. It uses a symmetrical four-heat dissipation array and forms an X-shaped heat dissipation duct at the junction of the array, which reduces the use of materials while improving the air flow efficiency and improving the heat dissipation effect of the entire radiator. At the same time, the preparation method of the radiator is simple, the material is saved, the heat dissipation effect is good, and the installation is convenient. It is very suitable for promotion and use in the field of new energy vehicles, especially in the field of heat dissipation of electric vehicle power batteries. BRIEF DESCRIPTION OF THE DRAWINGS
