    Abstract: An object is to provide a cooling unit which can reduce influence of radiation heat from a work piece having high temperature on members surrounding the work piece, prevent leak of coolant and vacuum leak, reduce cost, and prevent turning angle of a work piece conveying mechanism from being limited. The cooling unit is attached to the work piece conveying mechanism in the state that the outer wall part is in close contact with the to-be-cooled surface. The coolant stored in the lower space is evaporated by the heat transmitted from the to-be-cooled surface P via the outer wall part, and the to-be-cooled surface is cooled via the outer wall part by the heat of evaporation lost at the time of the evaporation of the coolant. The vapor in the lower space (coolant container) is discharged to the vacuum chamber by the vapor exhaust unit when the pressure of the vapor in the lower space reaches the fixed value or higher.

  • Patent number: 8756946
    Abstract: The method to improve the heating temperature of heat pump and the second-type high temperature absorption heat pump both belong to the field of heat pump technology. We can get the corresponding second-type high temperature absorption heat pump based on the second-type low temperature absorption heat pump as following ways. In the second-type low temperature absorption heat pump, we add the new added steam bleeding chamber, the new added absorber, then new added throttle or the new added liquid refrigerant pump, the new added solution pump and the new added solution heat exchanger. And some pipes are connected in a reasonable way. Or we adjust the connection of some pipes too. Then we can achieve correspondingly the three-stage high temperature second-type absorption heat pump or the high temperature second-type absorption heat pump with multi-terminal heating or the recuperative high temperature second-type absorption heat pump by combining some other components.
