After step 2, equipment heating source 900 bring into operation, the hydraulic oil of 902 second fluid chambers of fuel reserve tank is through fuel reserve tank outlet line 905 supply arrangement electro-heat equipment 901, hydraulic oil in equipment heating device 901 drains into first fluid chamber of fuel reserve tank 902 by fuel reserve tank in-line 903, and the hydraulic oil of first fluid chamber sequentially passes through hydraulic oil drain line 904, hydraulic oil oil-in flexible pipe, hydraulic oil transfer pipeline 100, hydraulic oil oil-out flexible pipe and hydraulic oil return line 907 and is back to second fluid chamber of fuel reserve tank 902；
Equipment heating source 900 initial operating stage, hydraulic fluid temperature is low, and hydraulic oil directly flows from hydraulic oil bypass line 300 in the flowing of hydraulic oil transfer pipeline 100, and hydraulic oil cools down without heat-exchanger rig 102；
nullEquipment heating device 901 runs a period of time and its internal hydraulic fluid temperature can be caused also to increase，The hydraulic fluid temperature of first fluid chamber in therefore equipment heating device 901 is expelled to fuel reserve tank 902 also raises，Fuel reserve tank temperature sensor 908 or hydraulic oil transfer pipeline temperature sensor 103 detect that the temperature of hydraulic oil reaches certain high temperature (more than 60 degrees Celsius)，Hydraulic oil bypass valve 301 cuts out，Hydraulic oil cools down through heat-exchanger rig 102，Now the cooling line electromagnetic valve 206 on cooling line 200 starts，Cooling line 200 comes into operation，Cooling line 200 carries out heat exchange with the high-temperature liquid force feed in hydraulic oil transfer pipeline 100 at heat-exchanger rig 102，High-temperature liquid force feed is cooled down，Making the low temperature hydraulic oil cooled down by heat-exchanger rig 102 is that second fluid chamber being again back to fuel reserve tank 902 continues supply arrangement electro-heat equipment 901 through hydraulic oil transfer pipeline 100.
Wherein the operation principle of cooling line 200 is:
After condenser 203, cryogenic high pressure gas liquid mixture is become from compressor 202 high temperature and high pressure gas out, it is then passed through reservoir 204 and carries out gas-liquid separation formation cryogenic high pressure liquid, it is then passed through device for drying and filtering 205 and carries out except water remove impurity, it is then passed through throttling arrangement 207 and forms Low temperature low pressure liquid, Low temperature low pressure liquid forms low-temp low-pressure gas liquid mixture through heat exchange in heat-exchanger rig 102, low-temp low-pressure gas liquid mixture carries out gas-liquid separation through gas-liquid separator 201 and forms low temperature low pressure gas, then low temperature low pressure gas is compressed forming high temperature and high pressure gas through compressor 202 again, the most above-mentioned circulation, thus the hydraulic oil of the hydraulic oil transfer pipeline 100 through heat-exchanger rig 102 is cooled down by cooling line 200.Wherein the effect of the cooling line bypass valve 208 in cooling line 200 is that the pressure in cooling line 200 persistently raises when reaching certain value, and cooling line bypass valve 208 is opened and carried out pressure release and play a protective role cooling line 200；The effect of cooling line electromagnetic valve 206 is when cooling line 200 is inoperative, and the liquid placing cooling line electromagnetic valve 206 front flow in compressor 202 backward so that compressor 202 damages, and plays a protective role.

Accumulation of energy pipe is external, and the inlet of protecting against shock accumulation of energy radiator and liquid outlet are positioned at the first collecting tank 501 and side of the second collecting tank 502.
The method of work of described radiator:
Equipment heating source initial operating stage, temperature of liquid is relatively low, cooling fan does not starts, liquid is entered in the first collecting tank of protecting against shock accumulation of energy radiator by inlet, the shunting liquid bath internal resistance of protecting against shock accumulation of energy radiator is less under normal circumstances or non-resistance, then, in liquid is introduced into the first collecting tank, then dispelling the heat during shunting liquid bath, enter back into the second collecting tank, finally leave protecting against shock accumulation of energy radiator from liquid outlet；When the shunting liquid bath internal resistance of protecting against shock accumulation of energy radiator is bigger, owing to the pressure in now accumulation of energy pipe is less, enter in accumulation of energy pipe with regard to some liquid, along with liquid is in the rising of accumulation of energy intraluminal fluid position, air in compress energy storage pipe, pressure in accumulation of energy pipe is also raised, pressure in final accumulation of energy pipe reaches equal with the pressure at inlet, now the liquid velocity at inlet slows down, pressure at inlet reduces the most therewith, along with the pressure at inlet reduces, enter the liquid in accumulation of energy pipe owing to pressure is higher than at inlet, return in the first collecting tank, then dispelling the heat during shunting liquid bath, enter back into the second collecting tank, finally leave protecting against shock accumulation of energy radiator from liquid outlet.
Because the mobility of air is good, substantially not having hysteresis quality, in protecting against shock accumulation of energy radiator, air runs into the moment of impulsive force, the most immediately compression and action, and this action completed in moment, will not have hysteresis quality and use fatigue as mechanical damping.
