Working principle of the present invention is as follows:
When needing fried, the starting of thermal medium heat riser.Thermal medium after heating is situated between through the heat on thermal medium pipe 5-2-3
Mass flow enters to hold 5-2-5 to flow into thermal medium pipe 5-2-3, and flows out from the thermal medium outflow end 5-2-4 of thermal medium pipe 5-2-3.Meanwhile
Hydraulic pump startup, the conduction oil in heat conduction fuel tank summarize the entrance that inlet tube 5-3 enters in the heat exchanger of head end through first
Straight tube.Due to the flow direction of conduction oil and thermal medium on the contrary, event relative velocity is big, the effect of heat transmitting is good.Further, since thermal medium
The heat medium temperature that the heat medium temperature at the 5-2-5 of end is higher than at thermal medium outflow end 5-2-4 is flowed into, if therefore heat exchanger tube 5-2-2
Shape be uniformly arranged along its length, then certainly will cause thermal medium flow into end 5-2-5 place and thermal medium outflow end 5-2-4 at
Heat exchange is uneven, and in the present invention, heat exchanger tube is set as the different multiple semiellipse pipes of axial length along its length, so that changing
Heat exchange property of the heat pipe at thermal medium outflow end 5-2-5 flows into the heat exchange property of end 5-2-4 better than thermal medium, and heat transfer effect is more
It is good uniform, it is not likely to produce extra thermal stress.And semiellipse pipe design so that conduction oil flowing acceleration change more frequency
It is numerous and quick, further increase heat exchange performance.
Conduction oil is completed to summarize outlet 5-4 outflow from first after heating, into eight heat-transfer pipe 7-3.Conduction oil
Heat rapidly enters the oil in fried basin, so that the oil heating in fried basin carrys out fry.If temperature is excessively high in fried basin,
Reduce the output flow of hydraulic pump or close hydraulic pump, slows down to heating oily in fried basin.
After the completion of frying, air pump starting, coolant liquid provides the coolant liquid that device provides and sprays through the spray head on spray tube.It is cold
But liquid reduces the temperature of fin type condensing tube, realizes the precooling of air-flow.The gas of fin type condensing tube output is through air pump
13 enter in the cold pipe 8-3 of biography.The heat in fried basin is absorbed into the low-temperature airflow for passing cold pipe 8-3, so that the oil in fried basin
Fast cooling is cooling.Increase service life oily in fried basin.
