Since the battery packs of vehicles are densely arranged, the input and output power are large, and the batteries are often buried inside the car, the battery heats up more seriously. Water-cooled radiators are now mostly used for heat dissipation.

[0003] There are many existing technologies for water cooling radiators, such as:

[0005] During use, the existing water-cooled radiator dissipates heat by attaching a water pipe to the surface of the battery pack. However, after the cooling water enters the water inlet of the water pipe and flows out from the water outlet, the temperature of the water in the water pipe away from the water inlet becomes higher and higher, making it difficult to quickly remove the heat from the surface of the battery pack, resulting in poor heat dissipation effect of the battery pack close to the water outlet.

[0006] Therefore, a new energy vehicle battery water-cooled radiator and a heat dissipation method thereof are proposed. Summary of the invention

[0007] The object of the present invention is to provide a water-cooled radiator for a new energy vehicle battery and a heat dissipation method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0008] In order to solve the above technical problems, one of the purposes of the present invention is to provide a water-cooled radiator for a new energy vehicle battery, comprising a water-cooling pipe, the water-cooling pipe comprising a symmetrical first channel and a second channel, a second channel being arranged between the first channels, the first channel and the second channel being connected and bent to form an S-shape, a battery being arranged between the first channel and the second channel, and a support plate being arranged at the bottom of the water-cooling pipe;

[0009] A baffle is provided inside the second channel, and the baffle is used to divide the internal space of the second channel into two halves along the axis. An extension plate is provided on the top of the baffle, and the extension plate passes through the second channel to the outside. A heat sink is provided on the surface of the extension plate. Both ends of the first channel are provided with docking joints, and the docking joints are used to dock with a water inlet and a water outlet. A plurality of bearings are provided inside the first channel, and the bearings are arranged in a stepped manner and fixed inside the first channel. A heat sink assembly is provided in the bearing, and the heat sink assembly is driven to rotate when water flows through the first channel, and the heat sink assembly is used to blow air to the heat sink.

[0010] As a further improvement of the present technical solution, the heat dissipation assembly includes a turbine plate rotatably arranged above the bearing, and the turbine plate is driven to rotate by the impact of water flow. An extension rod is provided at the center of the turbine plate, and the extension rod passes through the first channel and a main gear is provided at the end. A sub-gear is vertically meshed above the main gear, and a fan blade is provided at the end of the sub-gear.

[0011] As a further improvement of the technical solution, the heat dissipation components in the first channel are arranged in three groups, and the heat dissipation components are arranged in an ascending slope.

[0012] As a further improvement of the technical solution, the side walls of the first channel and the second channel are provided with fitting grooves, and the curvature of the surface of the fitting groove fits with the surface of the battery.

[0013] As a further improvement of the technical solution, a limiting groove corresponding to the battery is opened on the surface of the support plate, a through hole is opened inside the limiting groove, and symmetrical auxiliary holes are provided on both sides of the limiting groove.

[0014] As a further improvement of the technical solution, a barrier pad is provided on the inner wall of the through hole, and the barrier pad is used to increase the friction between the through hole and the side wall of the battery.

[0015] As a further improvement of the technical solution, the extension plate arranged above the baffle plate increases in height from both sides toward the middle, and heat sinks are provided on the surfaces of the extension plate.

[0016] As a further improvement of the present technical solution, the baffle plate is made of metal copper.

[0017] The second object of the present invention is to provide a water-cooling method for a new energy vehicle battery, comprising any one of the above-mentioned water-cooling radiators for a new energy vehicle battery, comprising the following steps:

[0018] S1. Insert the battery into the limiting groove on the surface of the support plate, so that the bottom of the battery fits with the barrier pad, and the fixed battery pack fits the first channel and the second channel side wall in the fitting groove. Since the fitting groove fits with the battery surface, the contact area between the first channel and the second channel and the battery pack is increased;

[0019] S2. By placing a baffle plate inside the second channel, the baffle plate is made of metal copper, and the extension plate arranged on the top of the baffle plate is made of the same material as the baffle plate. When the cooling water passes through the extension plate, it conducts heat to the outside. The surface of the extension plate is provided with a plurality of heat sinks to accelerate the heat dissipation.

[0020] S3. The extension plate arranged above the baffle plate increases in height from both sides to the middle part, so that the heat sink arranged on the surface of the extension plate can cover the entire range of the fan blades during the blowing process, thereby improving the heat dissipation effect of the heat sink.

[0022] 1. In the water-cooled radiator of the new energy vehicle battery, the cooling water impacts the turbine plate when passing through the first channel. The turbine blades arranged on the surface of the turbine plate rotate under the impact of the water flow. The surface of the turbine plate is provided with an extension plate to drive the main gear to rotate coaxially. When the main gear rotates, the sub-gear is driven to mesh and rotate at the same time, so that the fan blades arranged on the surface of the sub-gear blow air to the heat sink, thereby accelerating the heat dissipation efficiency of the heat sink, reducing the temperature of the cooling water, and thus accelerating the cooling efficiency of the battery pack.

[0023] 2. In the water-cooled radiator for new energy vehicle batteries, the battery is inserted into the limiting groove on the surface of the support plate so that the bottom of the battery fits with the barrier pad, and the fixed battery pack fits into the fitting grooves provided on the side walls of the first channel and the second channel. Since the fitting grooves fit with the battery surface, the contact area between the first channel and the second channel and the battery pack is increased. When the coolant flows through the first channel and the second channel, the heat on the surface of the battery pack can be taken away to the maximum extent.

[0024] 3. In the water-cooled radiator for new energy vehicle batteries, the battery is inserted into the limiting groove on the surface of the support plate so that the bottom of the battery fits with the barrier pad, and the fixed battery pack fits with the first channel and the second channel side walls in the fitting groove. Since the fitting groove fits with the battery surface, the contact area between the first channel and the second channel and the battery pack is increased. When the coolant flows through the first channel and the second channel, the heat on the surface of the battery pack can be taken away to the maximum extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] One of the purposes of the present invention is to Figure 1-Figure 9 As shown, a water-cooled radiator for a new energy vehicle battery is provided, including a water-cooling pipe, the water-cooling pipe including a symmetrical first channel 100 and a second channel 300, the second channel 300 is arranged between the first channels 100, the first channel 100 and the second channel 300 are connected and bent to form an S shape, a battery is arranged between the first channel 100 and the second channel 300, and a support plate 200 is arranged at the bottom of the water-cooling pipe;

[0043] A baffle plate 301 is provided inside the second channel 300, and the baffle plate 301 is used to divide the internal space of the second channel 300 into two halves along the axis. An extension plate 302 is provided on the top of the baffle plate 301, and the extension plate 302 passes through the second channel 300 to the outside. A heat sink 303 is provided on the surface of the extension plate 302. Both ends of the first channel 100 are provided with docking joints 101, and the docking joints 101 are used to dock the water inlet and the water outlet. A plurality of bearings 103 are provided inside the first channel 100, and the bearings 103 are arranged in a stepped manner and fixed inside the first channel 100. A heat sink assembly 400 is provided in the bearing 103. When water flows through the first channel 100, the heat sink assembly 400 is driven to rotate, and the heat sink assembly 400 is used to blow air to the heat sink 303.

[0044] The improvement of this embodiment is that the cooling water impacts the turbine plate 401 when passing through the first channel 100. The turbine blades arranged on the surface of the turbine plate 401 rotate under the impact of the water flow. The extension plate 302 arranged on the surface of the turbine plate 401 drives the main gear 403 to rotate coaxially. The rotation of the main gear 403 drives the sub-gear 404 to mesh and rotate, so that the fan blades 405 arranged on the surface of the sub-gear 404 blow air to the heat sink 303, thereby accelerating the heat dissipation efficiency of the heat sink 303, reducing the temperature of the cooling water, and thus accelerating the cooling efficiency of the battery pack.

[0045] Taking into account that the battery is prone to generate a large amount of heat energy during discharge, the internal chemical reaction of the battery will be accelerated when working at high temperature, which may lead to rapid attenuation of the battery capacity, thereby affecting the service life of the battery. In order to speed up the heat dissipation of the battery, the heat dissipation component 400 includes a turbine plate 401 rotatably arranged above the bearing 103, and the impact of water flow drives the turbine plate 401 to rotate. An extension rod 402 is provided at the center of the turbine plate 401, and the extension rod 402 passes through the first channel 100 and a main gear 403 is provided at the end thereof. A sub-gear 404 is vertically meshed above the main gear 403, and a fan blade 405 is provided at the end of the sub-gear 404. By placing a baffle plate 301 inside the second channel 300, the baffle plate 301 is made of metal copper, and a baffle plate 301 is provided at the top thereof. The extended plate 302 and the baffle plate 301 are made of the same material. When the cooling water passes through the extended plate 302, it conducts heat to the outside. A plurality of heat sinks 303 are provided on the surface of the extended plate 302. The heat sink 303 accelerates the dissipation of heat. When the cooling water passes through the first channel 100, it impacts the turbine plate 401. The turbine blades provided on the surface of the turbine plate 401 rotate under the impact of the water flow. The extended plate 302 provided on the surface of the turbine plate 401 drives the main gear 403 to rotate coaxially. When the main gear 403 rotates, it drives the sub-gear 404 to mesh and rotate, so that the fan blades 405 provided on the surface of the sub-gear 404 blow air to the heat sink 303, thereby accelerating the heat dissipation efficiency of the heat sink 303, reducing the temperature of the cooling water, thereby accelerating the cooling efficiency of the battery pack and improving the service life of the battery.

[0046] When the cooling water passes through the first channel 100 and the second channel 300, the cooling water passes through the water inlet of the first channel 100, passes through the second channel 300 and flows out from the water outlet of the first channel 100, while the cooling water takes away the heat from the surface of the battery, the cooling water near the water inlet of the first channel 100 is blocked by the turbine blades on the surface of the turbine plate 401, and the water flow velocity near it is reduced. In order not to affect the heat dissipation effect of other heat dissipation components 400, the heat dissipation components 400 in the first channel 100 are arranged in three groups, and the heat dissipation components 400 are arranged in an upward slope. By setting the heat dissipation components 400 in an upward slope, the impact on the heat dissipation components 400 inside the first channel 100 is reduced, thereby ensuring the blowing effect of the heat dissipation components 400.

[0047] When cooling water passes through the first channel 100 and the second channel 300 to cool the battery, the cooling effect is not ideal due to the small fitting surface. Therefore, in order to improve the cooling effect on the battery, the side walls of the first channel 100 and the second channel 300 are provided with fitting grooves 102, and the curvature of the surface of the fitting grooves 102 fits with the battery surface. By providing the fitting grooves 102 on the side walls of the first channel 100 and the second channel 300, the fitting grooves 102 fit with the battery surface, thereby increasing the contact area between the first channel 100 and the second channel 300 and the battery pack. When the cooling water passes through the first channel 100 and the second channel 300, it can quickly take away the heat on the surface of the battery pack, thereby improving the cooling effect of the device.

[0048] When the battery is in contact with the surface of the support plate 200 during installation, the heat dissipation effect of its bottom is poor. Therefore, a limiting groove corresponding to the battery is provided on the surface of the support plate 200, a through hole 201 is provided inside the limiting groove, and symmetrical auxiliary holes 203 are provided on both sides of the limiting groove. During the placement and installation of the battery, the bottom of the battery is inserted into the limiting groove. Since the through hole 201 is provided at the bottom of the limiting groove, the surface heat of the battery bottom is taken away during the circulation of external air, thereby improving the heat dissipation effect of the battery bottom.

[0049] During the installation of the battery, because it is a battery for new energy vehicles, there are often bumpy sections when the car is driving, which can easily cause the battery to loosen and affect the power supply to the vehicle. In order to improve the shock absorbing ability of the battery, a barrier pad 202 is provided on the inner wall of the through hole 201. The barrier pad 202 is used to increase the friction between the battery side wall. During the installation of the battery, the bottom of the battery is inserted into the limiting groove provided on the surface of the support plate 200. Since the inner wall of the limiting groove is provided with a barrier pad 202, the barrier pad 202 is made of rubber, and the barrier pad 202 can fit with the bottom of the battery. At the same time, the barrier pad 202 increases the friction on the bottom of the battery. When the vehicle travels to a bumpy section, the battery is prevented from shaking and loosening, thereby improving the shock absorbing ability of the battery pack and ensuring the normal power supply to the new energy vehicle.

[0050] Taking into account that during the process of the heat dissipation assembly 400 blowing air to the heat sink 303, when the heat sink 303 close to the first channel 100 is higher, it is easy to affect the heat dissipation effect of the heat sink 303 far away from the first channel 100, therefore, the extension plate 302 arranged above the baffle plate 301 increases from both sides to the middle part, and the surface of the extension plate 302 is provided with heat sink 303. When the water flow hits the turbine plate 401, the turbine plate 401 drives the main gear 403 provided on the top of the extension rod 402 to rotate coaxially, so that the sub-gear 404 meshing at the top of the main gear 403 rotates, thereby driving the fan blades 405 to blow air to the surface of the heat sink 303. Since the extension plate 302 arranged above the baffle plate 301 increases from both sides to the middle part, the fan blades 405 can fully cover the heat sink 303 provided on the surface of the extension plate 302 during the blowing process, thereby improving the heat dissipation effect of the heat sink 303.

[0051] When in use, the battery is inserted into the limiting groove on the surface of the support plate 200, so that the bottom of the battery fits with the barrier pad 202, and the fixed battery pack fits in the fitting groove 102 where the side walls of the first channel 100 and the second channel 300 are located. Since the fitting groove 102 fits with the surface of the battery, the contact area between the first channel 100 and the second channel 300 and the battery pack is increased. The docking joint 101 is connected to the water pump of the coolant. When the water pump draws the coolant to flow through the first channel 100 and the second channel 300, the heat on the surface of the battery pack can be taken away to the maximum extent.

[0052] By placing a baffle plate 301 inside the second channel 300, the baffle plate 301 is made of metal copper, and the extension plate 302 arranged on the top of the baffle plate 301 is made of the same material as the baffle plate 301. When the cooling water passes through the extension plate 302, it conducts heat to the outside. The surface of the extension plate 302 is provided with a plurality of heat sinks 303. The heat sinks 303 accelerate the dissipation of heat. When the cooling water passes through the first channel 100, it impacts the turbine plate 401. The turbine blades arranged on the surface of the turbine plate 401 rotate under the impact of the water flow. The extension plate 302 arranged on the surface of the turbine plate 401 drives the main gear 403 to rotate coaxially. The main gear When the wheel 403 rotates, the sub-gear 404 is driven to mesh and rotate, so that the fan blades 405 arranged on the surface of the sub-gear 404 blow air to the heat sink 303, thereby accelerating the heat dissipation efficiency of the heat sink 303, reducing the temperature of the cooling water, and thus accelerating the cooling efficiency of the battery pack; the fan blades 405 blow air to the surface of the heat sink 303, and because the extension plate 302 arranged above the baffle plate 301 increases from both sides to the middle part, the fan blades 405 can cover the entire range of the heat sink 303 on the surface of the extension plate 302 during the blowing process, thereby improving the heat dissipation effect of the heat sink 303.

[0053] The second object of the present invention is to provide a water-cooling method for a new energy vehicle battery, comprising any one of the above-mentioned water-cooling radiators for a new energy vehicle battery, comprising the following steps:

[0054] S1. Insert the battery into the limiting groove on the surface of the support plate 200, so that the bottom of the battery fits with the barrier pad 202, and the fixed battery pack fits the first channel 100 and the side wall of the second channel 300 in the fitting groove 102. Since the fitting groove 102 fits with the surface of the battery, the contact area between the first channel 100 and the second channel 300 and the battery pack is increased;

[0055] S2. By placing a baffle plate 301 inside the second channel 300, the baffle plate 301 is made of metal copper, and the extension plate 302 arranged on the top of the baffle plate 301 is made of the same material as the baffle plate 301. When the cooling water passes through the extension plate 302, it conducts heat to the outside. The surface of the extension plate 302 is provided with a plurality of heat sinks 303 to accelerate the heat dissipation. When the cooling water impacts the heat dissipation component 400 when passing through the first channel 100, the turbine blades arranged on the surface of the turbine plate 401 rotate under the impact of the water flow. The extension plate 302 arranged on the surface of the turbine plate 401 drives the main gear 403 to rotate coaxially. When the main gear 403 rotates, it drives the sub-gear 404 to mesh and rotate, so that the fan blades 405 arranged on the surface of the sub-gear 404 blow air to the heat sink 303;

[0056] S3. The extension plate 302 arranged above the baffle plate 301 increases in height from both sides to the middle, so that the heat sink 303 arranged on the surface of the extension plate 302 can cover the entire range of the fan blade 405 during the blowing process, thereby improving the heat dissipation effect of the heat sink 303.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.

When the main gear (403) rotates, it drives the sub-gear (404) to mesh and rotate, so that the fan blades (405) arranged on the surface of the sub-gear (404) blow air to the heat sink (303); S3. The extension plate (302) disposed above the baffle plate (301) increases in height from both sides toward the middle, so that the heat sink (303) disposed on the surface of the extension plate (302) can fully cover the fan blades (405) during the blowing process, thereby improving the heat dissipation effect of the heat sink (303).
