AI Technical Summary

Technical Problem

Existing automotive liquid heaters use thick film or positive temperature coefficient thermistor as heating elements, resulting in lower heating capacity and heat dissipation capacity and occupying a larger volume in the car.

Method used

Using a technical solution of double-layer flow path and double-layer heating element, the heating area is expanded, the heating power is increased, and the overall volume is reduced through the stacking design of double-layer flow paths and the stacking arrangement of double-layer heating elements.

Benefits of technology

It achieves a larger heat dissipation area and higher heating power, reduces the volume of the water tank, adapts to more types of vehicles, and reduces flow resistance at the same flow rate, matching the requirements of various OEMs for flow resistance.

Abstract

Disclosed are a medium heating device and a vehicle. The medium heating device comprises: a housing, having an accommodating cavity, wherein a first liquid pipe and a second liquid pipe are provided on the housing; and a first flow channel and a second flow channel, accommodated in the accommodating cavity. The housing has a second direction y, and the first flow channel and the second flow channel are stacked in the second direction y; and in the second direction y, a first heating element is stacked on the side of the first flow channel distant from the second flow channel, and a second heating element is stacked on the side of the second flow channel distant from the first flow channel. The technical solution that the two flow channels and the two heating elements are stacked is used in the present application, a larger heat dissipation area is achieved, the size of a water tank is reduced while the heating power is increased, and the present invention can be adapted to a wider range of vehicle models.
