Description

Technical Field

[0001] This utility model relates to the field of dual-screen technology, and in particular to a water-cooled dual-screen for new energy vehicles. Background Technology

[0002] With the rapid development of new energy vehicle technology, in-vehicle displays have evolved from traditional single instrument panels to dual-screen or even multi-screen displays that integrate information display, entertainment control, and vehicle status monitoring. Dual-screen displays typically include an instrument panel and a central control screen, with the instrument panel on the left and the central control screen on the right. By concentrating the original control buttons on the display screens, the convenience of driving operation and driving experience can be improved.

[0003] However, during long-term operation, the display screen and its associated circuit board will generate a lot of heat. If heat dissipation is not timely, it can easily lead to screen lag, response delay, or even hardware damage, affecting the safety and lifespan of the device.

[0004] However, commercially available solutions typically employ air-cooling to reduce the heat generated by the display screen during operation. For example, patent number CN222440123U proposes a magnesium alloy dual-screen for new energy vehicles. This screen uses a heat-conducting plate to absorb heat from the circuit board and display screen, and then transfers the heat to the outside air through a heat conductor. It also uses an exhaust fan and vents to convectively dissipate heat from the inside of the casing, achieving a rapid cooling effect. Although this cooling method has a protective mesh inside the vents, the mesh can affect the airflow speed and also makes it difficult to prevent fine dust from entering the casing, thus affecting the lifespan of the circuit board and display screen. Summary of the Invention

[0005] The purpose of this invention is to overcome the problem of low heat dissipation efficiency of dual-screen displays in new energy vehicles in the prior art, and to provide a water-cooled dual-screen display for new energy vehicles. It achieves efficient heat dissipation of the display screen and circuit board through a water-cooling structure with dual heat-conducting plates and dual cooling pipes, ensuring stable operation of the equipment, preventing the entry of external dust, and extending the service life of the equipment.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A water-cooled dual-screen display for new energy vehicles includes a bottom shell frame and a top shell frame that snaps into the bottom shell frame. A first heat-conducting plate is integrally molded within the bottom shell frame using an injection molding process. A second heat-conducting plate is interference-fitted within the top shell frame. The first heat-conducting plate has an inlet hole and an outlet hole. An inlet pipe passes through the inner wall of the inlet hole, and an outlet pipe passes through the inner wall of the outlet hole. A first cooling pipe connects the inlet pipe and the outlet pipe. A first water channel is also formed on the top of the first heat-conducting plate, and the first cooling pipe is embedded in the first water channel. The second heat-conducting plate... A second water channel is provided at the bottom of the hot plate, and a second cooling pipe is embedded in the second water channel. The water inlet of the second cooling pipe is connected to the water inlet of the first cooling pipe, and the water outlet of the second cooling pipe is connected to the water outlet of the first cooling pipe. Two screen mounting slots are provided at intervals on the top of the second heat-conducting plate, and two display screens are installed in the two screen mounting slots. Two circuit boards electrically connected to the display screens are provided on the first heat-conducting plate below the two display screens. The inner wall of the top shell frame above the second heat-conducting plate also has a protective plate mounting slot, and a transparent protective plate is installed in the mounting slot.

[0007] Furthermore, the inner wall of the bottom shell frame is symmetrically provided with several snap-fit ​​parts, and the inner wall of the top shell frame extends downward with snap-fit ​​parts that engage with the snap-fit ​​parts.

[0008] Furthermore, the screen mounting slot is also provided with several elongated through holes at equal intervals.

[0009] Furthermore, a temperature detection unit is also provided on the first heat-conducting plate, and the temperature detection unit is electrically connected to the circuit board.

[0010] Furthermore, the first heat-conducting plate is also provided with an overheat protection unit, which is electrically connected to the circuit board.

[0011] Furthermore, both the first cooling pipe and the second cooling pipe are heat-conducting hoses.

[0012] Furthermore, both the first heat-conducting plate and the second heat-conducting plate are made of thermally conductive metal material and are tightly attached to the first cooling pipe and the second cooling pipe, respectively.

[0013] Furthermore, the circuit board is securely connected to the first heat-conducting plate by four rectangular array of connecting posts, and the bottom of the circuit board is in contact with the first cooling pipe.

[0014] Compared with existing technologies, the water-cooled dual-screen for new energy vehicles provided by this utility model has the following beneficial effects: This invention uses a first heat-conducting plate and a second heat-conducting plate to absorb the heat from the circuit board and the display screen respectively, and works in conjunction with a first cooling pipe and a second cooling pipe to absorb the heat from the first heat-conducting plate and the second heat-conducting plate, thereby achieving efficient heat dissipation for the circuit board and the display screen. The heat dissipation effect is better than that of traditional air cooling. The first heat-conducting plate of this utility model is integrally formed with the bottom shell frame, and the second heat-conducting plate is interference-fitted with the top shell frame. Combined with the snap-fit ​​structure of the bottom shell and the top shell, the overall assembly is firm and has good shock resistance.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] like Figures 1-3As shown, this example provides a water-cooled dual-screen for a new energy vehicle, including a bottom shell frame 1 and a top shell frame 2. The bottom shell frame 1 and the top shell frame 2 are connected by a snap-fit ​​to form a closed space, which can prevent external dust from entering. The bottom shell frame 1 has several symmetrically arranged snap-fit ​​parts 101 around its inner wall. The snap-fit ​​parts 101 are protruding structures. The top shell frame 2 has correspondingly downward extending buckle parts 201 around its inner wall. The buckle parts 201 are groove structures that fit the protrusions. The two are fastened and fixed by snapping the snap-fit ​​parts 101 and the buckle parts 201.

[0020] like Figure 3 As shown, a first heat-conducting plate 3 is integrally formed inside the bottom shell frame 1 by injection molding. The first heat-conducting plate 3 is made of aluminum alloy, which has good thermal conductivity and formability. The first heat-conducting plate 3 has an inlet hole and an outlet hole, which are spaced apart. An inlet pipe 5 passes through the inlet hole and can be connected to the outlet end of the automotive coolant circulation system. An outlet pipe 6 passes through the outlet hole and can be connected to the return end of the coolant circulation system. A first cooling pipe 7 is connected between the inlet pipe 5 and the outlet pipe 6. The first cooling pipe 7 is a silicone thermally conductive hose, which has temperature resistance, thermal conductivity and flexibility. The top of the first heat-conducting plate 3 has a first water channel groove that matches the shape of the first cooling pipe 7. The first cooling pipe 7 is embedded in the first water channel groove and is tightly attached to the groove wall of the first water channel groove by thermally conductive silicone to ensure efficient heat transfer.

[0021] The first water channel is S-shaped and coiled, which can increase the contact area between the first cooling pipe 7 and the first heat-conducting plate 3 and increase the heat dissipation efficiency.

[0022] like Figure 4 As shown, a second heat-conducting plate 4 is interference-fitted inside the top shell frame 2. The second heat-conducting plate 4 is the same as the first heat-conducting plate 3, and is made of aluminum alloy, which has good thermal conductivity and formability. A second water channel is opened at the bottom of the second heat-conducting plate 4, and a second cooling pipe 8 is embedded in the second water channel. The second cooling pipe 8 is the same as the first cooling pipe 7, and is a silicone thermally conductive hose, which has the same temperature resistance, thermal conductivity and flexibility as the thermally conductive hose made of the same material. The inlet end of the second cooling pipe 8 is connected to the inlet end of the first cooling pipe 7 through a T-connector, and the outlet end of the second cooling pipe 8 is connected to the outlet end of the first cooling pipe 7 through a T-connector, forming a parallel water cooling circuit, so that the coolant can flow through the first cooling pipe 7 and the second cooling pipe 8 at the same time.

[0023] In this example, the second water channel is arranged along the edge of the second heat-conducting plate 4, which can cool the heat at the outer edge of the second heat-conducting plate 4, causing the heat to concentrate in the middle, while the first heat-conducting plate 3 is cooled. This causes the higher temperature to move towards the lower temperature, creating a vortex-like flow of heat, i.e. Figure 6As indicated by the arrow, this helps improve heat dissipation.

[0024] Alternatively, the first heat-conducting plate 3 and the second heat-conducting plate 4 can also be heat exchange plates. When using heat exchange plates, water channels adapted to the cooling pipes need to be opened on the surface of the heat exchange plates to ensure that the cooling pipes and the heat exchange plates are in close contact to maintain heat transfer efficiency.

[0025] like Figure 3 As shown, two screen mounting slots 401 are spaced apart on the top of the second heat-conducting plate 4. Two displays 10 are fixed in the two screen mounting slots 401 with glue. The two displays 10 are the instrument panel screen and the central control screen, respectively. The instrument panel screen is the left display screen 10, and the central control screen is the right display screen 10.

[0026] like Figure 3 and Figure 5 As shown, each screen mounting slot 401 has 6 elongated through holes 203 at equal intervals. The connecting wires of the display screen 10 pass through the elongated through holes 203 and connect to the circuit board 9 below. At the same time, since the heat generated by the display screen 10 is much greater than that of the circuit board 9, the display screen 10 is in close contact with the second heat-conducting plate 4. The heat generated by the display screen 10 can be diffused into the enclosed space through the elongated through holes 203 and absorbed by the first heat-conducting plate 3.

[0027] Meanwhile, since the display screen 10 is in close contact with the second heat-conducting plate 4, the heat generated by the display screen 10 can be quickly transferred to the second heat-conducting plate 4, and then absorbed and cooled by the second cooling pipe 8.

[0028] like Figure 3 As shown, two circuit boards 9 are respectively provided on the first heat-conducting plate 3 directly below the two display screens 10. The circuit boards 9 are fastened to the first heat-conducting plate 3 by four rectangular array connecting posts 14 and are electrically connected to the corresponding display screens 10. The connecting post 14 is made of a heat-conducting material, which is the same as the material of the first heat-conducting plate 3 and the second heat-conducting plate 4. This allows the circuit board 9 to dissipate heat efficiently. By adjusting the height of the connecting post 14, the bottom of the circuit board 9 can directly contact the first cooling pipe 7, bypassing the heat transfer process of the first heat-conducting plate 3.

[0029] The inner wall of the top shell frame 2 is provided with a protective plate mounting groove 202 above the second heat conduction plate 4. A transparent protective plate 11 is fixed in the protective plate mounting groove 202 with glue. The transparent protective plate 11 is made of tempered glass film material, which can touch the screen, while isolating dust and protecting the display screen 10.

[0030] In addition, the first heat-conducting plate 3 is equipped with a temperature detection unit 12 and an overheat protection unit 13 by welding or plugging, both of which are electrically connected to the circuit board 9 by wires.

[0031] It should be added that a circulation pump (not shown in the figure) is connected to the inlet pipe 5. The circulation pump is electrically connected to the circuit board 9, and the operating speed of the circulation pump can be controlled through the circuit board 9.

[0032] In this embodiment, the first cooling pipe 7 and the second cooling pipe 8 are connected to the vehicle's circulating coolant system via an external water pipe (not shown in the figure).

[0033] The temperature detection unit 12 collects the internal temperature data of the bottom shell frame 1 and the top shell frame 2 in real time and sends it to the circuit board 9. The circuit board 9 can control the speed of the circulating pump according to the temperature signal, thereby adjusting the flow rate of the coolant in the first cooling pipe 7 and the second cooling pipe 8. When the temperature exceeds the preset threshold, the overheat protection unit 13 is triggered, cutting off the power supply to the circuit board 9 to achieve overheat protection.

[0034] The working principle of this embodiment is as follows: the coolant provided by the automotive coolant circulation system is split by the inlet pipe 5 and enters the first cooling pipe 7 and the second cooling pipe 8 respectively. As the heat flows through the first cooling pipe 7, the heat absorbed by the first heat-conducting plate 3 is absorbed by the circuit board 9. As the heat flows through the second cooling pipe 8, the working heat of the display screen 10 is absorbed by the second heat-conducting plate 4. After absorbing heat, the coolant merges and flows back to the vehicle's coolant circulation system through outlet pipe 6, completing the heat dissipation cycle.

[0035] Meanwhile, the temperature detection unit 12 monitors the temperature in real time, and the overheat protection unit 13 triggers protection in case of abnormality to ensure safe operation of the equipment.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
