AI Technical Summary

Problems solved by technology

The analysis found that the patent has the following deficiencies: first, there is the thermal resistance of the aluminum plate; second, there is the contact thermal resistance between the heat pipe and the aluminum plate; third, the aluminum plate needs a half-moon arc groove and many screw holes, and the processing and installation are relatively complicated; four. The heat dissipation fins and the condensation section are installed nestedly, the installation is more complicated, and there is contact thermal resistance between the metals; the fifth is that the thickness of the heat conduction plate is uneven, which will cause slightly uneven temperature of the coil

The analysis found that the patent has the following deficiencies: first, the processing and installation of heat pipes with concave-convex structures are more complicated; second, there are both contact thermal resistance and metal thermal resistance in the interlocking part; third, the plane after interlocking cannot guarantee a better plane The fourth is that the consumption of metal materials is more

The heat pipe heat dissipation technology proposed in Chinese patent 88105470.4 is characterized in that multiple heat pipes are vertically inserted into the coil, and the gaps around the heat pipes are filled with thermally conductive fillers. Compared with metal, it is still a poor conductor and has a large thermal resistance; the heat pipe protrudes from the upper part of the iron remover, which is not conducive to natural heat dissipation

Its shortcomings are as follows: first, it is difficult to solve the sealing problem of the lead wires of the coil, thereby destroying the vacuum degree of the heat pipe; second, the aluminum condensation section and the steel intermediate partition are not easy to weld; third, the tubular array condensation section is vertically drawn from the upper part of the iron remover , not conducive to natural convection heat dissipation

[0009] It can be seen from the above-mentioned published technical documents that due to the defects of the heat pipe structure in the prior art, the heat pipe heat dissipation technology of the electromagnetic iron remover currently researched and developed still has problems such as poor heat dissipation effect, high temperature, and uneven temperature. The common defects are: 1. There are many additional thermal resistances, such as metal thermal resistance, contact thermal resistance, filler thermal resistance, etc., which lead to a decrease in the heat dissipation performance of the heat pipe, and the heat dissipation effect is not good; In the electromagnetic coil of ironware, the actual heat dissipation process is that each heat pipe operates independently, and there is no match or complementarity between them, resulting in the quality of local heat dissipation in the electromagnetic coil, which is completely determined by the heat dissipation effect of the heat pipe located there. The electromagnetic coil itself has a phenomenon of uneven heating. Therefore, the temperature in the local area with a large heat generation in the electromagnetic coil continues to maintain a high level, which affects the normal use of the electromagnetic coil. In severe cases, the electromagnetic coil is burned.
