Abstract

The invention provides a high-voltage PTC liquid heating assembly for heat management of new energy automobiles, and solves the technical problem that the existing new energy automobiles are insufficient in heat supply in winter and high in production cost. The high-voltage PTC liquid heating assembly is provided with a control box, and a high-voltage connector and a low-voltage connector are arranged on the control box; a control panel is arranged in the control box, and both the high-voltage connector and the low-voltage connector are connected with the control panel; the high-voltage PTC liquid heating assembly is further provided with a heating aluminum base and a water tank, the heating aluminum base is fixedly connected with the water tank and the control box, a PTC heating component is arranged on the heating aluminum base and is provided with a circuit board, and the circuit board is connected with the control panel; a partition is arranged in the water tank and divides a heating cavity enclosed by the heating aluminum base and the water tank into an upper layer and a lower layer, the water tank is further provided with a water inlet pipe and a water outlet pipe, the water inlet pipe is communicated with the lower layer, and the water outlet pipe is communicated with the upper layer. The high-voltage PTC liquid heating assembly can be widely applied to the field of heating of new energy automobiles.

Description

technical field [0001] The invention relates to a heating device, in particular to a high-pressure PTC liquid heating assembly for thermal management of a new energy vehicle. Background technique [0002] In the field of new energy vehicles, the comfort of the winter compartment and the charging and discharging of the power battery require a certain amount of heat. Without the waste heat of the traditional car engine, an electric heating system must be used to meet it. Since thermal management is required in multiple positions of the vehicle, the simple air-side PTC has great limitations and increases production costs. And the IGBT element on the control board in the existing PTC heating device is often damaged due to heating, and the life is short, which greatly affects the stability of its use. Contents of the invention [0003] The present invention aims at the technical problems of insufficient winter heat supply and high production cost of existing new energy vehicle...
