Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation, in particular to a novel radiator plastic water chamber structure. Background Art

[0002] The radiator is one of the components of the automobile engine water cooling system, and its structure mainly includes a water inlet chamber, a water outlet chamber, a main plate base radiator core and other parts. The water chamber material is mainly divided into plastic material and all-aluminum material, among which the plastic water chamber is more common. When the plastic water chamber is injection molded, the root of the pipe mouth can only be flush with the inside of the water chamber body and cannot be inserted to the bottom. When the automobile engine is running, the engine cooling system starts and circulates, and the coolant enters the radiator from the water inlet, which produces an impact force on the radiator main plate, and bubbles are generated when the liquid refluxes, which easily leads to cavitation of the main plate. Therefore, in view of the above-mentioned defects of the prior art, the plastic water chamber structure of the radiator is improved, and the utility model is proposed. Utility Model Content
