Installation structure of cooling water tank and electrical control components of electromagnetic heating device

Abstract

The invention discloses a heat dissipation water tank and electrical control element mounting structure of an electromagnetic heating apparatus. The mounting structure comprises a heat dissipation water tank and electrical control elements; the heat dissipation water tank comprises side walls and a bottom wall; each electrical control element is tightly locked on the outer surface of the bottom wall or a certain side wall of the heat dissipation water tank through a fastening part, and the bottom wall or the side wall is a metal wall; an annular ridge which is connected end to end is formed in a position, close to the edge of the corresponding electrical control element, of the metal wall in a stamping manner; the annular ridge extends along the edge region of the electrical control element; a connecting point between the screw thread fastening part and the metal wall is positioned outside a part which is surrounded by the annular ridge; and the part, which is surrounded by the annular ridge, of the metal wall is tightly attached to the corresponding electrical control element. The annular ridge disclosed by the invention can play an effect of preventing the metal wall from deforming, so that each attached part is not deformed or warped caused by screwing or pulling tightly, the flatness of the metal wall in each attached position can be ensured, and efficient heat dissipation of the electrical control element by the heat dissipation water tank can be realized.

Problems solved by technology

[0003] The heat dissipation water tank of the existing water-cooled electromagnetic heating device is only responsible for cooling the electromagnetic coil, and the electrical control components will also generate a lot of heat during the working process, which also requires effective heat dissipation, but in the prior art, it is difficult to fix the electrical control components This is mainly due to the following two reasons: 1. If the electrical control components are fixed on the tank wall by threaded fasteners, the tank wall will be subject to the tension or pressure of the threaded fasteners However, local warping and deformation occur, which makes the electrical control components unable to fit tightly on the surface of the tank wall, and a large air gap is formed between the two, which in turn makes the thermal resistance of the heat dissipation path large and the heat dissipation is not smooth, so it is difficult to rely on the tank wall of the heat dissipation water tank Effective heat dissipation for electrical control components; 2. The wall of the cooling water tank is not suitable for drilling bolt holes (installation holes), because once the (installation holes) appear, there is a danger of water seepage and affect the safety of use
