Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted refrigerators, and specifically to a heat dissipation device for a vehicle-mounted refrigerator applying a superconducting heat transfer plate. Background Art

[0002] A vehicle-mounted refrigerator refers to a refrigerated cabinet that can be carried in a vehicle. Vehicle-mounted refrigerators are a new generation of refrigeration and cold storage appliances that have become popular in the international market in recent years. There are mainly two types of vehicle-mounted refrigerators on the market. One is a semiconductor vehicle-mounted refrigerator, whose principle is to refrigerate by an electronic chip. The other is a compressor vehicle-mounted refrigerator. The compressor is a traditional technology of traditional refrigerators, with a low refrigeration temperature of -18°C to 10°C, high refrigeration efficiency, the ability to make ice and preserve freshness, and a large volume.

[0003] A non-phase change heat pipe is provided inside the superconducting heat transfer plate. The non-phase change heat pipe not only has great practical significance for current energy conservation, emission reduction, environmental protection, improving energy utilization efficiency, and realizing a low-carbon economy, but its more profound significance lies in the breakthrough of the heat transfer mechanism concept. Starting from specific heat transfer requirements, through comprehensive consideration of factors including heat transfer media, heating and cooling conditions, and carefully designing the heat transfer system, the microstructure of the heat transfer medium reaches a high degree of consistency, greatly improving the heat transfer efficiency.

[0004] Due to the compact structure of the vehicle-mounted refrigerator, it is convenient to move, but this also results in a small volume of the heat dissipation device, so the heat dissipation effect is not good, and thus the two cannot be balanced. Summary of the Invention

[0005] The purpose of the present invention is to provide a heat dissipation device for a vehicle-mounted refrigerator applying a superconducting heat transfer plate, aiming to solve the problem that the compact structure of the existing vehicle-mounted refrigerator and good heat dissipation effect cannot be balanced.

[0006] To achieve the above object, the present invention adopts the following technical solutions: The vehicle-mounted refrigerator heat dissipation device using a superconducting heat transfer plate includes a housing and at least three groups of heat dissipation plates arranged in the housing. The heat dissipation plates of each group are arranged between two adjacent heat dissipation plates of other groups. A heat conduction tube is fixedly installed on each group of heat dissipation plates. A hose is connected between all the heat conduction tubes. The heat conduction tubes and the hose are arranged in a serpentine shape. The other ends of the hoses at both ends are installed with a coolant circulation device. At least three rows of fan blades are arranged on one side of the heat dissipation plate. All the fan blades are evenly distributed in an array. The housing includes two parallel plates. On the corresponding surfaces of the two parallel plates, grid plates surrounding a circle are fixedly connected. One of the grid plates is sleeved on the other grid plate. The two parallel plates are provided with an adjusting device for adjusting the distance between the two parallel plates. A first equal-spacing adjusting mechanism for adjusting the position of each group of heat dissipation plates following the adjustment of the distance between the parallel plates is installed on the heat dissipation plate. A second equal-spacing adjusting mechanism for adjusting the position of each row of fan blades following the adjustment of the distance between the parallel plates and a synchronous driving mechanism for driving all the fan blades to rotate synchronously are installed on the fan blades.

[0007] In order to enable the present invention to have the function of circulating the coolant, a further technical solution of the present invention is that the coolant circulation device includes a heat absorption plate. A coolant pipeline is provided inside the heat absorption plate. A circulation pump is installed on one side of the heat absorption plate. The coolant pipeline, the circulation pump, and the heat conduction tube are connected in communication.

[0008] In order to enable the present invention to have a better heat conduction effect, a further technical solution of the present invention is that the heat absorption plate is a superconducting heat transfer plate.

[0009] In order to enable the present invention to have the function of changing the distance between the parallel plates, a further technical solution of the present invention is that the adjusting device includes an electric telescopic rod. The two ends of the electric telescopic rod are respectively connected to the two parallel plates.

[0010] In order to enable the present invention to have the function of adjusting the position of each group of heat dissipation plates following the adjustment of the distance between the parallel plates, a further technical solution of the present invention is that the first equal-spacing adjusting mechanism includes at least four groups of first scissor linkages. At least three first connection pins are arranged on the symmetry line of the front view projection of the first scissor linkages. The first connection pins are rotatably arranged at the connection points on the first scissor linkages. The three first connection pins are respectively fixedly connected to three groups of heat dissipation plates. The two groups of heat dissipation plates connected to the first connection pins at both ends are respectively fixedly connected to the two parallel plates.

[0011] A further technical solution of the present invention is that the four groups of first scissor linkages are arranged in a rectangular array.

[0012] In order to enable the present invention to adjust the position of each row of fan blades following the adjustment of the parallel plate spacing, a further technical solution of the present invention is that the second equal-spacing adjustment mechanism includes at least three groups of second scissor linkages. At least three rotating sleeves are arranged on the symmetry line of the front view projection of the second scissor linkages. The rotating sleeves are rotatably arranged on the second scissor linkages. A second connecting pin is rotatably connected inside the rotating sleeves. The fan blades are installed at one end of the second connecting pins. The second connecting pins at both ends are respectively rotatably connected to a left connecting plate and a right mounting plate. The left connecting plate and the right mounting plate are respectively fixedly connected to two parallel plates.

[0013] In order to enable the present invention to drive all the fan blades to rotate synchronously, a further technical solution of the present invention is that the synchronous drive mechanism includes a driven gear fixedly installed at the other end of the second connecting pin. Transmission gears are connected between the driven gears on the same group of second scissor linkages. The transmission gears are rotatably connected to the second scissor linkages through rotating shafts. The driven gears and the transmission gears on the same group of second scissor linkages are arranged in a Z shape. The synchronous drive mechanism further includes a drive assembly for synchronously driving one of the driven gears on each group of second scissor linkages to rotate.

[0014] In order to enable the present invention to synchronously drive one of the driven gears on each group of second scissor linkages to rotate, a further technical solution of the present invention is that the drive assembly includes a flexible rack meshing with the driven gear at one end of each group of second scissor linkages. A rotating wheel for fixing the position of the flexible rack is arranged inside the inner ring of the flexible rack. The rotating wheel is installed on the right mounting plate. A driving gear meshes with the flexible rack. A driving component for driving the driving gear to rotate is installed on one side of the driving gear.

[0015] A further technical solution of the present invention is that the driving component is a motor.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. When the present invention is in use, when moving the vehicle-mounted refrigerator, the housing is adjusted to the state with the smallest volume, so it is convenient to move. When a large amount of heat dissipation is required, the two parallel plates are adjusted to the position where the spacing can be achieved, so that the first equal-spacing adjustment mechanism drives each group of heat dissipation plates to move, so that each group of heat dissipation plates are separated from each other, and thus the heat dissipation effect of the heat dissipation plates is better.

[0018] 2. When the present invention is in use, when each group of heat dissipation plates are separated from each other, the second equal-spacing adjustment mechanism moves the fan blades along with the movement of the heat dissipation plates, so that the air flow blown by the fan blades can pass through all the heat dissipation plates, and further improves the heat dissipation efficiency when the heat dissipation plates are unfolded.

[0019] 3. When the present invention is in use, start the motor to drive the flexible rack with the driving gear. The movement of the flexible rack causes the driven gear and the transmission gear to rotate, so that all the fan blades rotate synchronously. And in any state, the second scissor link can make all the fan blades rotate synchronously. Such a setting does not require separate driving of the fan blades, so the number of motors used is reduced, and the production cost is saved. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following further describes the specific embodiments of the present invention with reference to the accompanying drawings.

[0027] As Figures 1-5As shown in the figure, a vehicle-mounted refrigerator heat dissipation device applying a superconducting heat transfer plate includes a housing 6 and at least three groups of heat dissipation plates 1 arranged in the housing 6. The heat dissipation plates 1 in each group of heat dissipation plates 1 are arranged between two adjacent heat dissipation plates 1 in other groups of heat dissipation plates 1. A heat conduction tube 2 is fixedly installed on each group of heat dissipation plates 1. A hose 3 is connected between all the heat conduction tubes 2. The heat conduction tubes 2 and the hose 3 are arranged in a serpentine shape. The other ends of the hoses 3 at both ends are installed with a coolant circulation device 4. At least three rows of fan blades 5 are arranged on one side of the heat dissipation plate 1. All the fan blades 5 are evenly distributed in an array. The housing 6 includes two parallel plates 61 parallel to each other. On the corresponding surfaces of the two parallel plates 61, a grid plate 62 surrounding a circle is fixedly connected. One of the grid plates 62 is sleeved on the other grid plate 62. The two parallel plates 61 are provided with an adjusting device for adjusting the distance between the two parallel plates 61. A first equal-spacing adjusting mechanism for adjusting the position of each group of heat dissipation plates 1 following the distance between the parallel plates 61 is installed on the heat dissipation plate 1. A second equal-spacing adjusting mechanism for adjusting the position of each row of fan blades 5 following the distance between the parallel plates 61 and a synchronous driving mechanism for driving all the fan blades 5 to rotate synchronously are installed on the fan blades 5.

[0028] In this specific embodiment, when moving the vehicle-mounted refrigerator, the housing 6 is adjusted to the state with the smallest volume, so it is convenient to move. When a large amount of heat dissipation is required, the two parallel plates 61 are adjusted to the position where the distance can be reached, so that the first equal-spacing adjusting mechanism drives each group of heat dissipation plates 1 to move, so that each group of heat dissipation plates 1 are separated from each other, so that the heat dissipation effect of the heat dissipation plates 1 is better. When each group of heat dissipation plates 1 are separated from each other, the second equal-spacing adjusting mechanism makes the fan blades 5 move along with the movement of the heat dissipation plates 1, so that the airflow blown by the fan blades 5 can pass through all the heat dissipation plates 1, further improving the heat dissipation efficiency in the case where the heat dissipation plates 1 are unfolded.

[0029] Specifically, the coolant circulation device 4 includes a heat absorption plate 41. A coolant pipeline is opened inside the heat absorption plate 41. A circulation pump 42 is installed on one side of the heat absorption plate 41. The coolant pipeline, the circulation pump 42 and the heat conduction tube 2 are communicated with each other.

[0030] Preferably, the heat absorption plate 41 is a superconducting heat transfer plate. The superconducting heat transfer plate is mainly made of a non-phase change heat pipe. The non-phase change heat pipe has the ability of ultra-high heat transfer heat flux density and good downward heat transfer ability, so the heat transfer efficiency is greatly improved.

[0031] Specifically, the adjusting device includes an electric telescopic rod 7. The two ends of the electric telescopic rod 7 are respectively connected to the two parallel plates 61. The distance between the two parallel plates 61 is adjusted by the telescopic movement of the electric telescopic rod 7.

[0032] Specifically, the first equal-spacing adjustment mechanism includes at least four groups of first scissor linkages 8. At least three first connecting pins 9 are arranged on the symmetry line of the front view projection of the first scissor linkages 8. The first connecting pins 9 are rotatably arranged at the connection points on the first scissor linkages 8. The three first connecting pins 9 are respectively fixedly connected to three groups of heat dissipation plates 1. The two groups of heat dissipation plates 1 connected to the first connecting pins 9 at both ends are respectively fixedly connected to two parallel plates 61. When the two parallel plates 61 move relative to each other, the two groups of heat dissipation plates 1 close to the two parallel plates 61 respectively keep their relative positions unchanged with respect to the two parallel plates 61, so that the first scissor linkages 8 extend. As a result, the group of heat dissipation plates 1 in the middle moves along with the extension of the first scissor linkages 8, so that the spacing between each group of heat dissipation plates 1 is the same.

[0033] Preferably, the four groups of first scissor linkages 8 are arranged in a rectangular array.

[0034] Specifically, the second equal-spacing adjustment mechanism includes at least three groups of second scissor linkages 10. At least three rotating sleeves 20 are arranged on the symmetry line of the front view projection of the second scissor linkages 10. The rotating sleeves 20 are rotatably arranged on the second scissor linkages 10. A second connecting pin 11 is rotatably connected inside the rotating sleeve 20. The fan blade 5 is installed at one end of the second connecting pin 11. The second connecting pins 11 at both ends are respectively rotatably connected to a left connecting plate 12 and a right mounting plate 13. The left connecting plate 12 and the right mounting plate 13 are respectively fixedly connected to the two parallel plates 61. When the two parallel plates 61 move relative to each other, the second scissor linkages 10 extend, so that the three rotating sleeves 20 move, and the spacing between the three rotating sleeves 20 is the same, so that the spacing between the fan blades 5 is the same.

[0035] Specifically, the synchronous driving mechanism includes a driven gear 14 fixedly installed at the other end of the second connecting pin 11. Transmission gears 15 are connected between the driven gears 14 on the same group of second scissor linkages 10. The transmission gears 15 are rotatably connected to the second scissor linkages 10 through rotating shafts. The driven gears 14 and the transmission gears 15 on the same group of second scissor linkages 10 are arranged in a Z shape. The synchronous driving mechanism further includes a driving component for synchronously driving one of the driven gears 14 on each group of second scissor linkages 10 to rotate. The transmission gear 15 at the Z-shaped turning point is arranged at the rotating joint of the second scissor linkages 10, and their rotation axes are collinear.

[0036] Specifically, the driving component includes a flexible rack 16 meshing with the driven gear 14 at one end of each group of second scissor linkages 10. A runner 17 for fixing the position of the flexible rack 16 is arranged inside the inner ring of the flexible rack 16. The runner 17 is installed on the right mounting plate 13. A driving gear 18 is meshed with the flexible rack 16. A driving component 19 for driving the driving gear 18 to rotate is installed on one side of the driving gear 18.

[0037] Preferably, the driving component 19 is a motor. Starting the motor causes the driving gear 18 to drive the flexible rack 16 to move. The movement of the flexible rack 16 causes the driven gear 14 and the transmission gear 15 to rotate, so that all the fan blades 5 rotate synchronously. Moreover, in any state, the second scissor link 10 can make all the fan blades 5 rotate synchronously. Such a setting does not require individual driving of the fan blades 5, thus reducing the number of motors used and saving the production cost.
