Abstract
An indirect thermoelectric cooling device comprises a thermoelectric cooling plate, in the indirect thermoelectric cooling device, a heat dispersing member is connected to the hot end of the thermoelectric cooling plate, and a cooling transmitting member is connected to the cold end of the thermoelectric cooling plate, characterized in that an inside mid-frame is provided between the heat dispersing member and cooling transmitting member, an outside mid-frame which is of a shape of sleeve is provided to surround the inside mid-frame, and the thermoelectric cooling plate is sandwiched between the inside mid-frame and the outside mid-frame. According to the present invention, there exist less connecting portions in the route of the cold or hot gas transferring, thus decreasing the heat resistant, and increasing the cooling or heating transmit efficiency, so that the heat dispersing and the cooling transmitting can be both realized in the same device. Since the heat exchanging is forced to be performed by means of a ventilator or fan, the generated cold gas can not be halted at the cold end, so that it is quick to get cold enough gas, and more cold gas can be generated.
