Equipment heating source initial operating stage, fluid temperature is lower, and cooling fan does not start, and liquid enters protecting against shock by inlet
In first collecting tank of accumulation of energy radiator, the shunting liquid bath internal resistance of protecting against shock accumulation of energy radiator is smaller under normal circumstances or nothing
Resistance, then liquid is introduced into the first collecting tank, is then radiated during by shunting liquid bath, is entered back into the second collection
Liquid bath finally leaves protecting against shock accumulation of energy radiator from liquid outlet；It is larger in the shunting liquid bath internal resistance of protecting against shock accumulation of energy radiator
When, since the pressure in accumulation of energy pipe at this time is smaller, some liquid is entered in accumulation of energy pipe, as liquid is in accumulation of energy intraluminal fluid
The raising of position, the air in compress energy storage pipe so that the pressure in accumulation of energy pipe also increases, the pressure in final accumulation of energy pipe reach with
Pressure at inlet is equal, and the liquid velocity at inlet slows down at this time, and the pressure at inlet also reduces therewith, with into
Pressure at liquid mouth reduces, and into the liquid in accumulation of energy pipe since pressure is higher than at inlet, returns into the first collecting tank
It is interior, it then radiates during by shunting liquid bath, enters back into the second collecting tank, finally leave protecting against shock from liquid outlet
Accumulation of energy radiator.
Because the motility of air is good, substantially without hysteresis quality, air, which encounters, in protecting against shock accumulation of energy radiator impact
The moment of power is just compressed and acts immediately, this movement is completed in moment, will not there is hysteresis quality and use as mechanical damping
Fatigue.
