Tank body 15, the top inlet porting of 15 side of tank body, the other side lower part outlet is set.The effect of fluid reservoir 6 is:
1. reducing the pressure that phase transformation takes hot loop 3, volume expansion of the fluid reservoir 6 for phase change medium in gasification provides space, makes phase transformation
Taking the total pressure of hot loop 3 reduces, and conducive to the phase transformation of phase change medium, can also phase transition temperature be made to reduce, in system structure intensity
It is hot highly beneficial with taking.2. liquid storage acts on, with the variation of heat power consumption, required phase change medium amount can also be increased and decreased, liquid storage
The phase change medium stored in tank 6 provides adjustment surplus for the flow adjusting of phase change medium.3. the liquid level of 250mm can produce
Raw 3.3Kpa pressure, increases the pressure of 7 entrance of circulating pump, overcomes cavitation.4. realizing gas using natural gravity effect
Liquid separation.
Top in the tank body 15 is provided with porous material layer 16, and the porous material layer 6 is exactly as its name suggests to have
The layer of material of porous structure primarily serves the effect for reducing fluid velocity, avoids the liquid pair entered by 6 entrance of fluid reservoir
6 lower liquid of fluid reservoir causes to disturb, and prevents gas from entering 7 entrance of circulating pump.
In addition, preferably way is also possible that the compressor 9 exports on active refrigeration corresponding with entrance circuit 4
It is provided with pressure detector 17, for carrying out pressure monitor to the outlet of compressor 9 and entrance.As shown in Fig. 2, the heat exchanger 5
Second entrance and compressor 9 outlet between be provided with return pipe 18, be provided with solenoid valve 19 on the return pipe 18.It is described to follow
The corresponding phase transformation in 7 outlet of ring pump, which takes, is provided with temperature detector 20 in hot loop 3.Temperature monitoring 20 is for detecting circulating pump 7
The temperature for exporting the liquid phase-change medium of discharge, is usually exactly a PT100 thermal resistance.When phase change medium temperature is excessively high or mistake
When low, by the control to 19 flow of solenoid valve, the cold medium flux for flowing through heat exchanger 5 can be changed, and then realize compression mechanism
The adjusting of cooling capacity, so that best match is realized in the calorific value of the refrigerating capacity of compressor 9 and heat load, more energy saving, the electricity
Magnet valve 19 is the impulse electromagnetic valve 19 by 220V power drives.
