Cubicle for inverter
First Claim
Patent Images
1. A cubicle for an inverter, comprising:
- a housing having a heat exchange wall and an internal chamber substantially completely surrounded by the housing, the heat exchange wall having a length and a width;
a switching element for an inverter which generates heat, mounted on the heat exchange wall of the housing to extend on the heat exchange wall along the length and width of the heat exchange wall such that the switching element is substantially completely surrounded by the housing; and
a cooling system comprising;
a continuous piping having a plurality of layers extending in a width direction of the heat exchange wall, along the heat exchange wall in a shape such that the continuous piping is folded back at the ends of the heat exchange wall, with a flow direction of a coolant in the piping alternating every layer; and
coolant flowing in the piping so that heat is diffused through the wall to simultaneously cool the housing and the inverter, whereby improving the heat diffusion of said cubicle for an inverter and eliminating the need for a heat sink for said cubicle for an inverter, resultantly reducing the external dimension of said cubicle for an inverter.
