Title: Cooling auxiliary device for condenser for cooling utilizing drainage for cooling
Inventor: WATANABE MASAHIRO
IPC: F24F13/22
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To improve cooling efficiency by a method wherein cooling by air is added and water is sprayed, and a condenser is derived of a heat of vaporization. SOLUTION: A drain hose 7 for cooling is connected to a water feed port 3, and when cooling is operated, water is stored in a container 1. When water attains a proper height, a switch 4 is brought into an 'ON' state, a motor-driven pump 2 is operated, and a water is sprayed upon a condenser 6 directly or through a hose. This constitution deprives a condenser 6 of a heat of vaporization by means of water to cool the condenser 6. Further, When a water level in the container 1 is lowered to a proper level, the switch 4 is turned off and racing of the motor-driven pump 2 is prevented from occurring. Besides, by forming a drain port 5 in the container 1, the drainage of a cooler is not disturbed.
