Water cooling device for model toy engine

Abstract

A water cooling device for a model toy engine comprises an engine, a radiator, a pipe, a cooler, and a water tank. The radiator is fixedly installed on the engine. The radiator contains water and has a water outlet and a water inlet on the top thereof. A pipe interconnects the water outlet and the water inlet. A cooler and a water tank are installed to connect with the pipe. The heat generated by the engine boils the water inside the radiator into vapor. The vapor flows into the pipe, and the cooler cools the vapor into water, and then the condensed water flows back to the radiator. The cooling cycle is repeated persistently to dissipate the heat generated by the engine. Therefore, the present invention can cool the engine without using any motor or pump. Further, the present invention can prevent the engine from overheat or burnout, avoid horsepower falling, and prolong the lifetime of the engine.

1 . A water cooling device for a model toy engine, comprising
 an engine;   a radiator arranged on said engine, having a plurality of fins on the surface thereof, being a hollow body containing water, and having a water outlet and a water inlet on the top thereof, wherein a pipe interconnects said water outlet and said water inlet, and said pipe has an opening and a cover covering said opening; and   a cooler arranged in said pipe.   
   
   
       2 . The water cooling device for a model toy engine according to  claim 1 , wherein a tube extends from below said water outlet into said radiator. 
   
   
       3 . The water cooling device for a model toy engine according to  claim 1 , wherein said radiator has a cover on the top thereof, and said cover has several screws; said screws pass through said radiator and fasten said radiator to said engine. 
   
   
       4 . The water cooling device for a model toy engine according to  claim 1  further comprising a water tank, wherein said water tank interconnects with said pipe, and said opening is formed on said water tank.
