Abstract

The invention provides a compact and inexpensive cooling device with high heat transfer efficiency and with easy maintenance. The cooling device includes a condenser (10), an evaporator (20), and a pair of refrigerant flow passages between them. In each of the condenser (10) and the evaporator (20), through holes (11a, 21a) are formed in parallel with each other. The condenser (10) is formed in a cylindrical shape and installed around the cooling head of the refrigerator by a clamp (14). The evaporator (20) is installed the outside. The refrigerant is liquefied in the condenser (10) by releasing its heat, flows down into the evaporator (20) through the flow passage and is vaporized in the evaporator (20) by absorbing heat from the outside. The vaporized refrigerator flows up and returns into the condenser (10).
