Description

Technical Field

[0001] This invention relates to the field of new energy vehicle battery system technology, specifically a new energy vehicle power battery tray with a heat pipe cooling device. Background Technology

[0002] As a key load-bearing and protective component of the power battery system, the heat dissipation performance of the power battery tray in new energy vehicles directly affects the working stability and service life of the power battery. In the existing technology, heat pipe heat dissipation structure is often used to dissipate heat from the power battery in the battery tray. The heat pipe absorbs the heat from the battery through the evaporation section and dissipates the heat to the external environment through the condensation section to achieve efficient heat dissipation.

[0003] However, existing battery trays with heat pipe cooling still have significant technical defects: the condensation section of the heat pipe is mostly directly exposed to the external environment. During long-term driving of new energy vehicles, the surface of the condensation section easily accumulates a large amount of dust, and there is a lack of targeted cleaning mechanisms. Dust accumulation will seriously hinder heat dissipation, causing the heat pipe cooling efficiency to decrease significantly over time. At the same time, some simple cleaning structures mostly use dry wiping methods, which have limited cleaning effect and cannot assist in enhancing the heat dissipation function during the cleaning process. This makes it difficult to meet the heat dissipation stability requirements of power batteries under long-term operating conditions, thus restricting the safety performance and service life of power batteries. Summary of the Invention

[0004] The purpose of this invention is to provide a power battery tray for new energy vehicles with a heat pipe cooling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A power battery tray for new energy vehicles with a heat pipe cooling device includes a tray body. Evenly distributed L-shaped heat pipes run through the side wall of the tray body. The horizontal section of the L-shaped heat pipe is an evaporation section, and the vertical section is a condensation section. Each condensation section has a movable ring on its outer side. An annular cleaning cotton is fixed to the inner wall of each movable ring and adheres to the outer wall of the vertical section of the L-shaped heat pipe. The annular cleaning cotton is connected to a moisturizing mechanism to maintain its humidity. The movable ring is connected to a lifting mechanism to move the movable ring up and down, allowing the annular cleaning cotton to wipe the condensation section of the L-shaped heat pipe.

[0008] Preferably, the positioning component includes a limiting cylinder fixedly connected to a fixed plate, a rotating rod passing through the limiting cylinder and rotatably connected thereto, a pin passing through the side wall of the limiting cylinder, a pin groove adapted to the pin on the side wall of the rotating rod, a movable rod rotatably connected to the end of the pin, a sliding rod rotatably connected to the other end of the movable rod, the sliding rod passing through the fixed plate and slidably connected thereto, a baffle fixed to the end of the sliding rod, the baffle being connected to the fixed plate via a first spring, wherein the baffle is connected to a traction member for traction of the baffle.

[0009] Preferably, the traction component includes a telescopic rod fixedly connected to the side wall of the fixed plate, a traction plate fixed to the end of the telescopic rod, a traction rope fixed to the side of the traction plate near the baffle, and the other end of the traction rope fixedly connected to the side wall of the baffle.

[0010] Preferably, the moisturizing mechanism includes a water injection pipe fixedly connected to the top of the moving ring, wherein the moving ring is hollow inside and communicates with the water injection pipe, and a plurality of water outlet holes are provided on the inner wall of the moving ring, the water outlet holes communicating with the hollow interior of the moving ring, and the water injection pipe is connected to a water injection assembly, which is used to inject cleaning fluid into the water injection pipe.

[0011] Preferably, the water injection assembly includes a water tank fixed to the outer wall of the tray body, a plurality of pressure cylinders evenly distributed at the bottom of the water tank, a piston slidably connected inside the pressure cylinder, the top of the piston being connected to the top of the pressure cylinder via a second spring, a branch pipe fixed to the bottom of the piston, the branch pipe penetrating the bottom of the pressure cylinder and slidably connected thereto, wherein the outer diameter of the branch pipe is adapted to the inner diameter of the water injection pipe, an inlet pipe and an outlet pipe are connected above the piston and on the inner wall of the pressure cylinder, the inlet pipe is connected to the water tank, the outlet pipe is connected to the branch pipe, and a stop block is fixed outside the branch pipe.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The new energy vehicle power battery tray moves the moving ring up and down through the lifting mechanism. The moving ring wipes the condensation section of the L-shaped heat pipe with an annular cleaning cotton to remove dust and ensure heat dissipation efficiency. At the same time, the moisturizing mechanism maintains the humidity of the annular cleaning cotton, which not only improves the cleaning effect, but also enhances the heat dissipation performance through the cooling effect of the moist annular cleaning cotton. This provides double protection for the stability of battery heat dissipation and effectively solves the problem of heat dissipation attenuation caused by dust accumulation on the L-shaped heat pipe during long-term driving, thereby improving the heat dissipation reliability and service life of the battery tray.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0022] In one embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 5A power battery tray for new energy vehicles with a heat pipe heat dissipation device includes a tray body 1. L-shaped heat pipes 2 are evenly distributed along the side wall of the tray body 1. The horizontal section of the L-shaped heat pipe 2 is an evaporation section 22, and the vertical section is a condensation section 21. Each condensation section 21 is externally equipped with a movable ring 5. An annular cleaning cotton 6 is fixed to the inner wall of the movable ring 5 and is in contact with the outer wall of the vertical section of the L-shaped heat pipe 2. The annular cleaning cotton 6 is connected to a moisturizing mechanism 4 to maintain the humidity of the annular cleaning cotton 6. The movable ring 5 is connected to a lifting mechanism 3 to move the movable ring 5 up and down, thereby enabling the annular cleaning cotton 6 to wipe the condensation section 21 of the L-shaped heat pipe 2.

[0023] In this embodiment, the battery tray primarily utilizes the L-shaped heat pipe 2 for battery heat dissipation during use. When the new energy vehicle is driven for an extended period, a certain amount of dust will accumulate on the surface of the vertical section of the L-shaped heat pipe 2, namely the condensation section 21, thus affecting the heat dissipation effect of the L-shaped heat pipe 2. At this time, the lifting mechanism 3 drives the moving ring 5 to move up and down repeatedly. The moving ring 5, in turn, drives the annular cleaning cotton 6 to move up and down repeatedly on the condensation section 21 of the L-shaped heat pipe 2. The annular cleaning cotton 6, through its up-and-down reciprocating motion, can wipe the condensation section 21 of the L-shaped heat pipe 2, improving the cleanliness of the condensation section 21 and thus ensuring the heat dissipation effect of the L-shaped heat pipe 2. Furthermore, the annular cleaning cotton 6 is connected to a moisturizing mechanism 4, which ensures that the surface of the annular cleaning cotton 6 remains moist. The moistened annular cleaning cotton 6 further enhances the cleaning effect on the condensation section 21. Furthermore, the moistened annular cleaning cotton 6 also cools the L-shaped heat pipe 2 during wiping. Specifically, the new energy vehicle power battery tray uses a lifting mechanism 3 to move the moving ring 5 up and down. The moving ring 5 wipes the condensation section 21 of the L-shaped heat pipe 2 with the annular cleaning cotton 6, removing dust to ensure heat dissipation efficiency. Simultaneously, the moisturizing mechanism 4 maintains the humidity of the annular cleaning cotton 6, improving both the cleaning effect and the cooling effect of the moistened annular cleaning cotton 6, thus enhancing heat dissipation performance. This dual protection ensures the stability of battery heat dissipation and effectively solves the problem of heat dissipation attenuation caused by dust accumulation on the L-shaped heat pipe 2 during long-term driving, improving the heat dissipation reliability and service life of the battery tray.

[0024] Please see Figure 3 , Figure 4 and Figure 5 The lifting mechanism 3 includes a connecting block 31 fixed on the outer wall of the moving ring 5. A support rod 32 is fixed at the bottom of the connecting block 31, and a limiting frame 33 is fixed at the bottom of the support rod 32. A turntable 34 is provided on the side of the limiting frame 33. A rotating component is connected to the side of the turntable 34 away from the limiting frame 33. The rotating component is used to drive the turntable 34 to rotate. A limiting post 35 is provided on the side of the turntable 34 close to the limiting frame 33. The limiting post 35 penetrates the limiting frame 33.

[0025] When the L-shaped heat pipe 2 needs to be cleaned, the rotating assembly drives the turntable 34 to rotate, and the limiting post 35 on the turntable 34 moves in a circular motion. Since the limiting post 35 passes through the limiting frame 33, its circular motion can be converted into a vertical pushing and pulling force on the limiting frame 33. This, in turn, drives the support rod 32, connecting block 31 and moving ring 5, which are fixedly connected to the limiting frame 33, to move in a vertical reciprocating linear motion along the L-shaped heat pipe 2. This achieves stable reciprocating movement of the moving ring 5, thereby driving the annular cleaning cotton 6 to continuously wipe and clean the condensing section 21 of the L-shaped heat pipe 2, ensuring heat dissipation efficiency.

[0026] Please see Figure 4 and Figure 5 The rotating assembly includes a rotating rod 36 fixedly connected to the side wall of the turntable 34. A fixing plate 38 is fixed to the bottom of the tray body 1. The rotating rod 36 passes through the fixing plate 38 and is rotatably connected to it. An impeller 37 is fixed to one end of the rotating rod 36 away from the turntable 34. The rotating rod 36 is connected to a positioning component, which is used to position the rotating rod 36.

[0027] When cleaning of the L-shaped heat pipe 2 is not required, the positioning component positions the rotating rod 36, thereby limiting the rotation of the turntable 34. When cleaning of the L-shaped heat pipe 2 is required, the airflow generated by the car's movement is used as the power source. The airflow impacts the impeller 37, driving the rotating rod 36 to rotate. The rotating rod 36 drives the turntable 34 to rotate synchronously. The fixing plate 38 at the bottom of the tray body 1 supports and limits the rotating rod 36, ensuring its stable rotation. This structure cleverly utilizes natural airflow to achieve self-sufficiency in power, eliminating the need for additional electric drive. This simplifies the structural design, reduces energy consumption, and ensures the stability and reliability of the turntable 34's rotation.

[0028] Please see Figure 4 The positioning component includes a limiting cylinder 39 fixedly connected to the fixed plate 38, a rotating rod 36 passing through the limiting cylinder 39 and rotatably connected to it, a pin 310 passing through the side wall of the limiting cylinder 39, a pin groove adapted to the pin 310 on the side wall of the rotating rod 36, a movable rod 311 rotatably connected to the end of the pin 310, a sliding rod 312 rotatably connected to the other end of the movable rod 311, the sliding rod 312 passing through the fixed plate 38 and slidably connected to it, a baffle 314 fixed to the end of the sliding rod 312, the baffle 314 being connected to the fixed plate 38 via a first spring 313, wherein the baffle 314 is connected to a traction member, the traction member being used to traction the baffle 314.

[0029] When cleaning of the L-shaped heat pipe 2 is not required, the first spring 313 pushes the baffle 314 to move the slide rod 312. Through the linkage of the movable rod 311, the pin 310 is inserted into the pin groove of the rotating rod 36, restricting the rotation of the rotating rod 36. When cleaning of the L-shaped heat pipe 2 is required, the baffle 314 is pulled by the traction component. The baffle 314 moves the slide rod 312. The slide rod 312 pulls the pin 310 through the movable rod 311, causing the pin 310 to exit the pin groove, thereby releasing the restriction on the rotating rod 36 and allowing it to rotate freely. This structure realizes convenient switching between positioning and unlocking of the rotating rod 36. The operation is simple and the positioning is stable, ensuring the controllability and stability of the working state of the rotating component.

[0030] Please see Figure 4 The traction component includes a telescopic rod 317 fixedly connected to the side wall of the fixed plate 38. A traction plate 316 is fixed to the end of the telescopic rod 317. A traction rope 315 is fixed to the side of the traction plate 316 near the baffle 314. The other end of the traction rope 315 is fixedly connected to the side wall of the baffle 314.

[0031] The traction component achieves traction of the baffle 314 through the telescopic movement of the telescopic rod 317. When cleaning of the L-shaped heat pipe 2 is required, the telescopic rod 317 extends and drives the traction plate 316 to move. The traction plate 316 pulls the baffle 314 through the traction rope 315. The baffle 314 drives the sliding rod 312 to move, and then the movable rod 311 links the pin rod 310 out of the pin groove, releasing the limit on the rotating rod 36. When cleaning of the L-shaped heat pipe 2 is not required, the telescopic rod 317 retracts, the traction rope 315 no longer pulls the baffle 314, and when the pin groove on the side wall of the rotating rod 36 aligns with the pin rod 310, the first spring 313 resets, thereby driving all components to return to their initial state, and the pin rod 310 re-inserts into the pin groove to complete the positioning.

[0032] Please see Figure 5 and Figure 6 The moisturizing mechanism 4 includes a water injection pipe 41 fixedly connected to the top of the moving ring 5. The moving ring 5 is hollow inside and communicates with the water injection pipe 41. The inner wall of the moving ring 5 is provided with a plurality of water outlet holes, which communicate with the hollow interior of the moving ring 5. The water injection pipe 41 is connected to a water injection assembly, which is used to inject cleaning fluid into the water injection pipe 41.

[0033] When the L-shaped heat pipe 2 needs to be cleaned, the lifting mechanism 3 drives the moving ring 5 to move up and down repeatedly. When the moving ring 5 moves to the highest point, cleaning fluid is injected into the water injection pipe 41. The water injection pipe 41 is connected to the hollow moving ring 5, allowing the cleaning fluid to flow into the interior of the moving ring 5. The water outlet holes evenly distributed on the inner wall of the moving ring 5 allow the cleaning fluid to seep out and wet the annular cleaning cotton 6 that is attached to the condenser section 21 of the L-shaped heat pipe 2, continuously maintaining the wet state of the annular cleaning cotton 6. This structure uses the hollow cavity of the moving ring 5 to achieve temporary storage and even distribution of the cleaning fluid. The humidity of the annular cleaning cotton 6 is precisely controlled through the permeation effect of the water outlet holes. This not only ensures the cleaning effect of the annular cleaning cotton 6, but also enhances the heat dissipation performance of the L-shaped heat pipe 2 through the cooling effect of the wet annular cleaning cotton 6. The structure is simple and has high moisturizing efficiency, effectively improving the heat dissipation stability of the battery tray.

[0034] Please see Figure 1 , Figure 2 and Figure 6 The water injection assembly includes a water tank 42 fixed to the outer wall of the tray body 1. A plurality of pressure cylinders 49 are evenly distributed at the bottom of the water tank 42. A piston 45 is slidably connected inside the pressure cylinder 49. The top of the piston 45 is connected to the top of the pressure cylinder 49 through a second spring 46. A branch pipe 43 is fixed at the bottom of the piston 45. The branch pipe 43 passes through the bottom of the pressure cylinder 49 and is slidably connected to it. The outer diameter of the branch pipe 43 is adapted to the inner diameter of the water injection pipe 41. A water inlet pipe 47 and a water outlet pipe 48 are connected above the piston 45 and on the inner wall of the pressure cylinder 49. The water inlet pipe 47 is connected to the water tank 42, and the water outlet pipe 48 is connected to the branch pipe 43. A stop block 44 is fixed outside the branch pipe 43.

[0035] When the moving ring 5 is about to reach its highest point, the lower end of the branch pipe 43 will insert into the water injection pipe 41. As the moving ring 5 continues to move upward, the water injection pipe 41 will squeeze the stop block 44. The stop block 44 drives the piston 45 to move upward through the branch pipe 43. As the piston 45 moves upward, it squeezes the cleaning liquid above it. The cleaning liquid then enters the branch pipe 43 through the water outlet pipe 48, and finally enters the moving ring 5 through the water injection pipe 41, thereby humidifying the annular cleaning cotton 6. When the moving ring 5 moves downward, the water injection pipe 41 no longer squeezes the stop block. When the piston 44 is squeezed, the piston 45 moves downward automatically under the action of the second spring 46. At this time, a negative pressure is formed above the piston 45, which then draws the cleaning fluid inside the water tank 42 through the water inlet pipe 47, ensuring the amount of cleaning fluid inside the pressure cylinder 49. In order to make the cleaning fluid flow in one direction, both the water inlet pipe 47 and the water outlet pipe 48 are equipped with one-way valves, and the water outlet pipe 48 is a flexible hose. This structure triggers automatic water injection through the lifting and lowering movement of the moving ring 5, without the need for additional power, realizing the precise replenishment and recycling of the cleaning fluid, and ensuring the continuous and stable operation of the moisturizing mechanism 4.

[0036] Working principle: This power battery tray dissipates heat from the power battery through an L-shaped heat pipe 2. The evaporation section 22 of the L-shaped heat pipe 2 absorbs heat from the battery, while the condensation section 21 dissipates the heat to the outside. When the car is moving, the airflow impacts the impeller 37, causing the rotating rod 36 to rotate, which in turn causes the limiting post 35 on the turntable 34 to make circular motion. Through the cooperation between the limiting post 35 and the limiting frame 33, the circular motion is converted into a vertical reciprocating force, which in turn drives the support rod 32, the connecting block 31, and the moving ring 5 along... The L-shaped heat pipe 2 moves up and down repeatedly, causing the annular cleaning cotton 6 on the inner wall of the moving ring 5 to wipe the condensing section 21 of the L-shaped heat pipe 2, removing surface dust to ensure heat dissipation efficiency. Under normal conditions, the pin 310 is inserted into the pin groove of the rotating rod 36, restricting the rotation of the rotating rod 36. When cleaning is required, the telescopic rod 317 extends and drives the traction plate 316 to move. The traction plate 316 pulls the baffle 314 through the traction rope 315, causing the pin 310 to exit the pin groove and releasing the restriction on the rotating rod 36. Meanwhile, when the moving ring 5 rises, the water injection pipe 41 squeezes the stop block 44, causing the piston 45 to move upward. The cleaning fluid in the pressure cylinder 49 is injected into the water injection pipe 41 through the water outlet pipe 48 and the branch pipe 43. After flowing into the hollow moving ring 5, it seeps out through the water outlet hole, wetting the annular cleaning cotton 6. This not only improves the cleaning effect, but also enhances heat dissipation through the cooling effect of the moist annular cleaning cotton 6. When the moving ring 5 falls, the second spring 46 drives the piston 45 to reset. The pressure cylinder 49 draws cleaning fluid from the water tank 42 through the water inlet pipe 47, realizing automatic replenishment and recycling of the cleaning fluid, thus providing double protection for the stability of battery heat dissipation.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
