Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of new energy automobile water heaters, in particular to a shell structure of an automobile heater. Background Art
[0002] The heating of new energy vehicles is achieved by heating the liquid through a heating plate. The heating plate is heated inside the heater, and the liquid is heated in the heater and then flows out. Then the hot air is blown into the car through a fan to form heating.
[0003] However, when current heaters are in use, the liquid inside the heater will expand after being heated, which will cause leakage. This is mainly because traditional heaters have only one seal, and leakage will occur after the first seal is broken. Traditional heaters have poor thermal insulation performance after heating, which leads to fast heat transfer and cannot achieve a good heating effect, which in turn causes excessive electricity consumption in new energy vehicles.
[0004] In order to solve the above problems, the present application proposes a shell structure of a car heater. Utility Model Content

[0007] A further technical improvement of the utility model is that a fixing groove is provided on the upper edge of the bottom shell, and a placement groove is provided on the bottom shell located outside the fixing groove, and the sealing member comprises: a first sealing member, the first sealing member is fixedly arranged in the fixing groove, the first sealing member and the upper shell are squeezed against each other to produce deformation to form a seal, and can achieve a first layer of sealing effect; a second sealing member, the second sealing member is plugged in the placement groove, the second sealing member is arranged inside the placement groove, a pressure strip is fixedly connected to the lower end of the edge of the upper shell, the pressure strip is abutted against the second sealing member, and can achieve a second layer of sealing effect.
[0008] A further technical improvement of the utility model is that the inner side wall of the protective shell is bonded with thermal insulation cotton, and the thermal insulation cotton is bonded with the outer side walls of the bottom shell and the upper shell.
[0009] A further technical improvement of the utility model is that the cross section of the first sealing member is arranged in a " " shape, and the inner end of the first sealing member is arranged flush with the inner end surface of the bottom shell.
[0010] A further technical improvement of the utility model is that a groove is provided at the outer end of the protective shell, and the number of the grooves is multiple and the spacings are equal.
