Box type cooling structure for controller

A box type cooling structure of a controller, the controller comprising a driving and controlling board, an Insulated Gate Bipolar Translator (IGBT) module and a film capacitor,

• wherein the box type cooling structure comprises an upper water channel substrate, a front water channel substrate, a left water channel substrate, a rear water channel substrate, a right water channel substrate and a lower water channel substrate sequentially enclosed in six directions of the controller, wherein water channel structures are arranged in the upper water channel substrate, the front water channel substrate, the left water channel substrate, the rear water channel substrate, the right water channel substrate and the lower water channel substrate;
• a water inlet is provided at a top of the upper water channel substrate, a first water outlet, a second water outlet, a third water outlet and a fourth water outlet are arranged in four corners of a bottom of the upper water channel substrate;
• a second water inlet communicating with the first water outlet is provided at a top of the front water channel substrate, and a fifth water outlet is provided at a bottom of the front water channel substrate;
• a third water inlet communicating with the second water outlet is provided at a top of the left water channel substrate, and a sixth water outlet is provided at a bottom of the left water channel substrate;
• a fourth water inlet communicating with the third water outlet is provided at a top of the rear water channel substrate, and a seventh water outlet is provided at a bottom of the rear water channel substrate;
• a fifth water inlet communicating with the fourth water outlet is provided at a top of the right water channel substrate, and an eighth water outlet is provided at a bottom of the right water channel substrate;
• and
• a sixth water inlet communicating with the fifth water outlet, a seventh water inlet communicating with the sixth water outlet, an eighth water inlet communicating with the seventh water outlet and a ninth water inlet communicating with the eighth water outlet are provided at a top of the lower water channel substrate, and a ninth water outlet is provided at a bottom of the lower water channel substrate.
