Example Embodiment

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like figure 1 and 2 As shown, a water heating heater with a grounding structure includes a water heater body 1 , a heat-dissipating metal plate 2 , an electric control board (above the heat-dissipating metal plate, not shown), a casing 3 , and a metal conductor 4 . The upper surface of the heat-dissipating metal plate 2 is in contact with the electric control board, which has IGBT transistors, and the heat-dissipating metal plate 2 is in close contact with the IGBT transistors. The heat dissipation of the electric control board is mainly the heat dissipation of the IGBT transistors, so the heat dissipation metal The plate 2 plays the role of dissipating heat for the IGBT transistor. The heat dissipating metal plate 2 in this embodiment is an aluminum plate, and may also be a copper plate or other metal material with good thermal conductiv...

Abstract

The invention discloses a water heating unit with ground structure, comprising a heating unit body, a heat-dissipating metal plate, an electrical board, and a housing; the upper surface of the heat-dissipating metal plate is in contact with the electrical board; the lower surface of the heat-dissipating metal plate is in contact with the heating unit body; the housing comprises a bottom and a sidewall made of insulating material, the inner side of the sidewall is provided with cylindrical feet, mounting lugs are extended out from the bottom, the cylindrical feet are of metal, an inner layer ofeach mounting lug is of metal, and the cylindrical feet are in contact with the inner layers of the mounting lugs. The water heating unit also comprises a metal conductor, one end of the metal conductor is connected with the heat-dissipating metal plate, and the other end of the metal conductor is connected with the cylindrical feet. The heat-dissipating metal plate and the mounting lugs are madeingenious use; the structure of the water heating unit need not be modified; the water heating unit is convenient and simple to manufacture and is very suitable for serving as PTC (positive temperature coefficient) water heating units of similar water tank structure; the water heating unit has no increased size, attractive appearance, good grounding and assembly conveniences and is more convenient to use.

Description

technical field [0001] The invention is designed in the field of new energy vehicles, in particular to a PTC water heating heater for new energy vehicles. Background technique [0002] In order to cope with the increasingly prominent contradiction between fuel supply and demand and environmental pollution, all countries in the world are promoting the development of new energy vehicles. Traditional cars have always used the waste heat of the engine as a heating heat source. This method depends on the engine of the car, that is to say, the heating in the car can only be implemented when the engine is working. In addition, the efficiency of this heating system is very low, and it takes 6-10 minutes to heat up after starting the engine in winter. But electric cars don't have an engine, and a hybrid car needs to be heated when the engine is stalled. [0003] At present, PTC ceramics have unique positive temperature coefficient and temperature resistance characteristics, which h...
