Description
The utility model relates to make the device of object cooling, and (be called for short: the vacuum freezing device), it mainly is included as the vacuum evaporation type refrigerating plant to particularly a kind of vacuum evaporation type refrigerating plant and the novel evaporative condenser that designs (is called for short: new condenser).
At present, with machine the method for object cooling is had: 1. to blow with blower fan; 2. extract the liquid level steam with pump; 3. with the refrigeration machine medium that cools, by the cooling medium object is lowered the temperature again.
Blower fan is to force flowing of surrounding air by the rotation of fan blade, and the air that flows through object can be taken away the heat of the temperature object higher than moving air, or takes away the gas that is evaporated by object, makes the object cooling.
Extract the liquid level steam with pump, make the object cooling.
Present refrigeration machine has: 1. steam compression type; 2. absorption; 3. semiconductor (thermoelectric (al) type).
Vapor compression type refrigerating system is made up of evaporimeter, compressor, condenser and control valve four parts.
Absorption system is made up of generator, condenser, evaporimeter and absorber four parts.
No matter be that blower fan blows, extract the liquid level steam or make the object cooling, all progressively carry out to interior of articles from body surface with refrigeration machine; The speed of cooling is generally slower, and is slower to the cooling of the bad object of heat conduction; Refrigerating efficiency is lower, improve refrigerating efficiency and cooling rate, will strengthen the temperature difference, and with the also obviously increase of increasing energy consumption of the temperature difference, the complete machine cost also increases, and machine volume also increases.
Condenser is big parts of refrigeration machine, and the quality of the performance of condenser influences the refrigeration of refrigeration machine significantly.
