HEAT CONTROL DEVICE FOR POWER EQUIPMENT

摘要

A heat control device for power equipment comprises a heat source (1), a heat sink substrate (2), a heat insulation layer (3), a cooling heat sink (4) and a temperature control switching unit. The heat source (1) contacted with the cooling heat sink (4) is placed on the cooling heat sink (4), the bottom of the heat source (1) is directly overlapped with the heat sink substrate (2), the heat insulation layer (3) is arranged around the heat sink substrate (2), and the temperature control switching unit is arranged on the heat sink substrate (2). The heat control device has good cooling performances at high temperatures and good heat insulation performances at low temperatures, the heat control device is also easy to manufacture, low in cost and reliable in performance.
