[0002] At present, the automobile radiator is an indispensable and important component in the cooling system of the automobile water-cooled engine, and is developing in the direction of lightness, high efficiency and economy. The radiator core should have sufficient flow area to allow the coolant to pass through, and it should also have sufficient air flow area to allow enough air to pass through to take away the heat transferred from the coolant to the radiator. At the same time, it must also have sufficient heat dissipation area to complete the heat exchange between the coolant, air and heat sink. The heat shield part is the core component of the radiator. Its function is to take away the heat of the internal coolant through the air flow on its surface. In order to improve the heat dissipation efficiency, the heat exchange capacity between the automotive radiator heat shield and the air is crucial. Utility Model Content

[0003] In view of this, the utility model provides a vehicle radiator heat insulation cover and a vehicle radiator, which improves the heat exchange capacity between the radiator and the air by improving the surface of the heat insulation cover of the vehicle radiator.

[0004] The technical solution of the embodiment of the utility model is implemented as follows: a vehicle radiator heat shield comprises a heat shield body, wherein the contact surface of the heat shield body with air is evenly provided with a plurality of protrusions for heat dissipation, wherein the protrusions are pyramid-shaped protrusions or well-shaped protrusions.

[0005] Further preferably, the heat insulation cover body is made of aluminum alloy material.

[0006] Further preferably, the plurality of protrusions are distributed in an array and tightly cover the contact surface.

[0007] Further preferably, a V-shaped gap is formed between the plurality of pyramid-shaped protrusions.

[0008] Further preferably, the middle of the well-shaped protrusion is recessed toward the heat insulation cover body to form a circular groove.

[0009] Further preferably, there are inverted X-shaped gaps between the plurality of well-shaped protrusions.

[0010] Further preferably, the height of the protrusion is in millimeter order.

[0011] Based on the same concept, the present application also provides a vehicle radiator, which adopts the vehicle radiator heat insulation cover as described above.

[0012] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0013] The utility model arranges a plurality of millimeter-level pyramid-shaped protrusions or well-shaped protrusions on the contact surface between the radiator heat insulation cover and the air to increase the contact area with the air, and when the heat dissipation air with a certain flow rate flows to the pyramid-shaped protrusion or well-shaped protrusion structure of the radiator heat insulation cover, due to the viscosity and temperature difference of the air, a vortex is formed in the V-shaped gap or circular groove of the radiator heat insulation cover, forming a role similar to that of an air bearing, which accelerates the flow of cold air on the surface of the radiator heat insulation cover on the one hand, and forms pressure pulsation inside the V-shaped gap or circular groove on the other hand, so as to facilitate the interaction between cold and hot air and improve the heat dissipation efficiency.
