Description

Technical Field

[0001] This utility model relates to an automotive injection molded part, and more particularly to an automotive injection molded part with heat dissipation function, belonging to the technical field of automotive injection molded parts. Background Technology

[0002] When a car is parked or driven outdoors, the car body will be exposed to direct sunlight. The metal materials of the car body have a certain thermal conductivity. When the car body is exposed to the sun or when the heat generated by the engine and other components is conducted to the car body, the car body will absorb heat, and the internal temperature of the car will rise rapidly.

[0003] When driving in summer, most people turn on the air conditioning system in advance to lower the temperature inside the car. However, the air conditioning system lowers the temperature of the air inside the car first. For the door area, the air inside the car needs to conduct heat slowly with the injection-molded parts of the door. The outside of the door is exposed to sunlight and is quite hot. Moreover, the injection-molded parts cool down slowly. As a result, even after the air inside the car is cooled down, the inside of the door remains at a relatively high temperature, which reduces the comfort of the passengers.

[0004] Therefore, there is an urgent need to improve automotive injection molded parts with heat dissipation functions to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an automotive injection molded part with heat dissipation function. By using exhaust pipe 1, exhaust pipe 2, and cooling pipe, the contact area between the cold air and the panel is increased, and the contact between the cold air and the panel is accelerated. The cold air passes through the inside of the panel, which accelerates the cooling speed of the car door injection molded part and makes the inner surface of the car door and the interior temperature more consistent with each other more quickly.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: an exhaust pipe 1, an exhaust pipe 2, and a panel.

One end of the cooling pipe is fixedly connected to the exhaust pipe 1 or the exhaust pipe 2, and the other end of the cooling pipe is connected to the air inlet pipe 1 or the air inlet pipe 2. The top of the exhaust pipe 1 and the exhaust pipe 2 is provided with a motor mounting surface. The interior of the exhaust pipe 1 and the exhaust pipe 2 is used to install a cooling fan assembly.

[0007] Preferably, both the first exhaust pipe and the second exhaust pipe have a connection hole 1 on the side near the panel, and a pipe groove is provided on the back of the panel. The pipe groove passes through the connection between the first exhaust pipe and the second exhaust pipe and the panel, and both the first air inlet pipe and the second air inlet pipe have a connection hole 2 on the side near the panel.

[0008] Preferably, one end of the cooling pipe is fixedly connected to the first connection hole, and the other end of the cooling pipe is fixedly connected to the second connection hole, and the cooling pipe is fixed inside the pipe groove.

[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] like Figures 1-6 As shown, the automotive injection molded part with heat dissipation function provided in this embodiment includes an exhaust pipe 1, an exhaust pipe 2, and a panel 3. The exhaust pipe 1 and the exhaust pipe 2 are fixedly connected to both ends of the back of the panel 3. An air inlet pipe 4 and an air inlet pipe 5 are fixedly connected to both sides of the panel 3. The exhaust pipe 1 and the exhaust pipe 2 are located inside the air inlet pipe 4 and the air inlet pipe 2. A plurality of cooling pipes 6 are fixedly connected to the back of the panel 3. One end of the cooling pipe 6 is fixedly connected to the exhaust pipe 1 or the exhaust pipe 2, and the other end of the cooling pipe 6 is connected to the air inlet pipe 4 or the air inlet pipe 2. The top of the exhaust pipe 1 and the exhaust pipe 2 is provided with a motor mounting surface 7. The exhaust pipe 1 is... The interior of exhaust pipe 2 is used to install the radiator fan assembly 8. The motor mounting surface 7 at the top of the exhaust pipe is used to install the motor. The motor drives the radiator fan assembly 8 to exhaust the air in the exhaust pipe. The cold air in the car enters from the air inlet pipe 4 and the air inlet pipe 2, passes through the cooling pipe 6 and enters the exhaust pipe. When the cold air passes through the cooling pipe 6, it takes away the heat of panel 3 and the inside of panel 3. The exhaust pipe 1, exhaust pipe 2 and cooling pipe 6 increase the contact area between the cold air and panel 3, and accelerate the contact between the cold air and panel 3. The cold air passes through the inside of panel 3, which accelerates the cooling speed of the door injection molded parts and makes the inner surface of the door and the interior temperature more consistent.

[0025] Furthermore, such as Figure 1 as well as Figure 6As shown, both exhaust pipe 1 and exhaust pipe 2 have connection holes 9 on the side near panel 3. A pipe groove 10 is provided on the back of panel 3. The pipe groove 10 passes through the connection between exhaust pipe 1 and exhaust pipe 2 and panel 3. Both air inlet pipe 4 and air inlet pipe 5 have connection holes 11 on the side near panel 3. One end of cooling pipe 6 is fixedly connected to connection hole 9, and the other end of cooling pipe 6 is fixedly connected to connection hole 11. Cooling pipe 6 is fixed in pipe groove 10. The cold air entering from air inlet pipe 4 flows into exhaust pipe 1 after passing through cooling pipe 6. The cold air entering from air inlet pipe 25 flows into exhaust pipe 2 after passing through another cooling pipe 6. When the cold air passes through cooling pipe 6, it carries away the heat of panel 3 and the inside of panel 3. Panel 3, exhaust pipe 1 and exhaust pipe 2 are a whole. Cooling pipe 6 and air inlet pipe are fixedly installed on the surface of panel 3.

[0026] Among them, such as Figure 1 As shown, both the first air inlet pipe 4 and the second air inlet pipe 5 have ventilation openings 12 at the top and are closed at the bottom. A dustproof net 13 is provided on the outside of the ventilation opening 12. Air enters from the top of the air inlet pipe, and the dustproof net 13 filters large particles in the air. Drainage holes 14 are provided at the bottom of the first air inlet pipe 4 and the second air inlet pipe 5. A plug 15 is provided at the drainage hole 14. Cooling water in the air is deposited at the bottom of the ventilation opening 12. When the plug 15 is opened, the accumulated water flows out from the drainage hole 14.

[0027] Among them, such as Figure 1 as well as Figure 6 As shown, the cooling fan assembly 8 includes a drive motor 801, a rotating shaft 802, and multiple sets of cooling blades 803. The drive motor 801 is fixedly connected to the motor mounting surface 7, and the rotating shaft 802 is fixedly connected to the output shaft of the drive motor 801. The multiple sets of cooling blades 803 are fixedly connected to the side of the rotating shaft 802. When the drive motor 801 rotates, it drives the rotating shaft 802 to rotate, and the rotating shaft 802 drives the cooling blades 803 to rotate. The cooling blades 803 blow air out from the lower ends of the exhaust pipe 1 and the exhaust pipe 2. The bottom of the rotating shaft 802 is provided with a fixing ring 16. The surface of the fixing ring 16 is hollowed out, and the center of the fixing ring 16 is connected to the rotating shaft 802 through a bearing. The air blown out by the cooling fan assembly 8 passes through the hollowed-out part of the fixing ring 16, and the fixing ring 16 fixes the bottom of the rotating shaft 802.
