Thermoregulator cover and thermoregulator assembly

The invention provides a thermolator cover and a thermolator assembly, and belongs to the technical field of automobile parts. The thermolator cover comprises a cover body and two nesting sleeves, and the cover body is provided with a cavity, two pre-buried holes and a sealing groove. And the cavity is communicated with a cooling liquid inlet pipe. The two nests are fixed to the two embedded holes respectively, and the cover body is connected with the thermolator base through the nests. The sealing groove is located in the top face of the cover body, surrounds the cavity and is located between the two embedded holes. The closer the cover body is to the embedded hole, the larger the connection force is, the larger the generated deformation is, and the larger the deformation of the sealing groove is correspondingly. The bottom wall of the sealing groove is gradually lowered in the direction away from the first datum line A. The first datum line A is perpendicular to the connecting line of the two embedded holes
