Cooling device

Abstract

The present invention relates to a cooling device, mainly comprises a carrying unit, a thermal insulation unit, and a temperature-lowering module. The thermal insulation unit is provided over a part of surface of the carrying unit for blocking heat transmission between the carrying unit and the outside. As the carrying unit is placed on the temperature-lowering module, a cooling chip in the temperature-lowering module is able to lower the temperature of the carrying unit and a biological sample. Furthermore, the thermal insulation unit is able to maintain the temperature of the carrying unit and biological sample, when the carrying unit is removed from the temperature-lowering module. Thereafter, a user can conveniently practice observation and experiment with respect to the biological sample, and avoid damaging the biological sample during experiment or transportation by the use of the cooling device.
