AI Technical Summary
Technical Problem
When spraying in insulation powder, the powder is unevenly adhered due to right angles in the existing liquid-cooled plate, which cannot meet the high insulation pressure resistance requirements, and there is a risk of breakdown.
Method used
Design the liquid-cooled plate to form a smooth transition area between the plane panel and the runner plate, and the insulating layer is applied to the side of the plane panel facing away from the runner plate to ensure uniform coating.
Benefits of technology
It realizes high insulation withstand voltage of liquid-cooled plates in high DC voltage tests, with extremely small leakage current, and the flat panel is not easily broken by high current, ensuring product safety and structural strength.

Abstract
The utility model provides a liquid cooling plate and a new energy automobile cooling device.The liquid cooling plate comprises a plane plate and a runner plate, one face of the plane plate is connected with one face of the runner plate, the plane plate is provided with a limiting groove, the limiting groove is used for installing a battery cell module, the runner plate is provided with an avoiding opening, the limiting groove corresponds to the avoiding opening, and the plane plate is provided with a plane area; a smooth transition area is formed between the inner side wall of the limiting groove and the plane area; the liquid cooling plate further comprises an insulating layer, and the insulating layer is used for coating the face, away from the runner plate, of the plane plate. When one surface of the surface plate is coated with the insulating layer, the smooth transition area can also be uniformly coated, so that a high DC voltage withstand test is carried out on the liquid cooling plate after coating is completed, the liquid cooling plate is not electrified at the moment, the leakage current is extremely small, and the surface plate is not easily broken down by high current, namely, the requirement of high insulation and voltage withstand is met, and it can be ensured that the product is not easily broken down. The surface plate is provided with a surface plate transition area, so that the structural strength can be improved, and deformation is not prone to occurring in the transportation aspect.
