Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to the frame of an automotive radiator grille. Background Technology

[0002] The car radiator is a heat dissipation component on a car, while the grille frame is a protective component installed on the outside of the radiator, which plays a role in supporting, blocking foreign objects, and expanding the heat dissipation area. However, the traditional grille frame heat dissipation method is relatively simple (relying only on air flow for heat dissipation), which has poor heat dissipation efficiency and increases the power of the radiator. Therefore, we proposed the car radiator grille frame. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automotive radiator grille frame, comprising two frames, front and rear, each frame including a supporting column and a grille plate;

[0009] Preferably, an installation hole is provided at the junction of the rhomboid support rib and the heat-conducting pipe; both ends of the heat-conducting pipe extend to the support column and are interconnected with the inner cavity of the support column.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This design utilizes a combination of heat conduction and convection to release heat. The sheet-like structure of the diamond-shaped support ribs increases the heat dissipation area and enhances the cooling effect. Low-temperature air flows through the ventilation gaps between the frame members and the grille plates, further assisting in cooling and forming a composite heat dissipation mode of passive air cooling and active liquid cooling.

[0018] Example:

[0019] Please see Figure 1-3 The present invention provides the following technical solution:

[0020] The car radiator grille frame includes two frames, front and rear, each frame including a support column 1 and a grille plate 2;

[0021] A ventilation gap is reserved between the front and rear frames; each frame is symmetrically equipped with support columns 1 on the left and right sides, and a grid plate 2 is installed between the adjacent support columns 1 on the left and right sides, and a ventilation gap is also reserved between the grid plates 2.

[0022] Both ends of the front and rear adjacent support columns 1 are equipped with fixing seats, which fix the two frames together; multiple connecting ribs 4 are also distributed between the front and rear adjacent support columns 1 to strengthen the connection between the front and rear frames.

[0023] Miniature pumps 3 are installed on the outer ends of the mounting bases at the upper right and lower left corners;

[0024] The inner cavities of both the support column 1 and the fixed base are hollow and connected to the micro pump 3.

[0025] The grid plate 2 has a pre-reserved heat conduction cavity, and diamond-shaped support ribs 5 are evenly arranged in the heat conduction cavity. The main body of the diamond-shaped support ribs 5 is a heat conduction sheet. A heat conduction pipe 6 is inserted through the middle of the heat conduction cavity. An installation hole is opened at the junction of the diamond-shaped support ribs 5 and the heat conduction pipe 6.

[0026] The two ends of the heat pipe 6 extend to the support column 1 and are interconnected with the inner cavity of the support column 1; the micro pump 3 in the upper right corner is responsible for introducing the exchange liquid into the support column 1, and then the exchange liquid flows into the heat pipe 6 along the inner cavity of the support column 1. The heat pipe 6 exchanges heat with the heat-conducting cavity through heat conduction, so that the grid frame can not only provide support and protection, but also play a role in heat dissipation and exchange, achieving multiple functions; while the micro pump 3 in the lower left corner can discharge the exchange liquid, which is convenient for the next re-injection of the exchange liquid.

[0027] Working principle:

[0028] The front and rear frames form a framework structure through supporting columns 1 and grid panels 2. Ventilation gaps are reserved between the frames and between the grid panels to ensure air circulation for heat dissipation and to provide structural support for the grids through a rigid structure. The supporting columns 1 are symmetrically distributed on both sides of the frame and serve as the main load-bearing components; the grid panels 2 connect adjacent columns to form a protective mesh to prevent the intrusion of foreign objects.

[0029] The fixed base is installed at both ends of the adjacent front and rear support columns 1, and the two frames are fixed as a whole by welding to ensure structural stability; the connecting ribs 4 are distributed laterally between the support columns 1 of the front and rear frames, and the deformation resistance between the frames is further improved by increasing the connection points, thus strengthening the overall rigidity.

[0030] The micro pump 3 in the upper right corner provides circulation power for the exchange fluid, pumping the low-temperature exchange fluid into the hollow cavity of the support column 1. The micro pump 3 in the lower left corner is responsible for discharging the high-temperature exchange fluid after heat absorption, and can be used to replace or replenish the exchange fluid in some scenarios.

[0031] The exchange fluid originates from the micro-pump in the upper right corner, flows into the support column 1 through the hollow structure of the fixed base, and flows downward or outward along the inner cavity of the column, entering the heat-conducting pipe 6 that penetrates the grid plate 2. After absorbing heat from the heat-conducting cavity of the grid plate 2, the temperature of the exchange fluid rises, and it flows back to the micro-pump 3 in the lower left corner through the other support column 1. The heat-conducting pipe 6 penetrates the heat-conducting cavity of the grid plate 2, serving as a flow channel for the exchange fluid, and conducts heat with the surrounding air / heat-conducting cavity through the pipe wall.

[0032] The main body of the diamond-shaped support rib 5 is a heat-conducting sheet, which is evenly distributed in the heat-conducting cavity to increase the contact area with air and improve the heat radiation efficiency; at the same time, it is fixed to the heat-conducting pipe 6 through the mounting hole, which strengthens the structural connection and optimizes the heat conduction path.

[0033] The grid plate 2 serves as the carrier of the heat conduction cavity, and its ventilation gap design accelerates airflow, further removing heat through convection. As the exchange liquid flows in the heat conduction pipe 6, it transfers heat to the diamond-shaped support ribs 5 and the grid plate 2 through the pipe wall.

[0034] Grille 2 contacts the outside air, releasing heat through heat conduction and convection; the sheet-like structure of the diamond-shaped support ribs 5 increases the heat dissipation area and enhances the heat dissipation effect. Low-temperature air flows through the ventilation gaps between the frame and the grille 2, further assisting in cooling, forming a composite heat dissipation mode of passive air cooling + active liquid cooling. Mechanical and heat dissipation integration: structural components such as support columns and grille 2 simultaneously undertake mechanical support and heat conduction functions, reducing the space occupation of independent heat dissipation components and achieving lightweight design.
