Description
Technical field
The present invention relates to a kind of multistage retractable earth pressure release damping device.
Background technique
Along with the development of electronic technology, chip power-consumption increases gradually, and due to the high efficiency of liquid-cooling heat radiation technology, in electronic equipment dissipating heat, the increasing liquid technology that adopts is dispelled the heat, but thereupon also along with a series of engineering problem needing to solve.When liquid cooled module takes out from liquid cooling electronic equipment, due to the selfsealings that liquid cooled module has, disconnect and namely form self-styled closure instantaneously, liquid can not be leaked from liquid cooling housing.Thus store a large amount of liquid at liquid cooled module or machine frame inside.
Liquid in module has certain expansibility, when ambient temperature rising or single module power up debugging around, because temperature raises, volume increases liquid in module, due to the sealing configuration of module, in the confined situation of volume, then pressure raises, the pressure that expansion of liquids causes is very large, can cause liquid cooled module, the damage of frame.
Therefore need the measure taked to be utilize pressure to make the corresponding increase of the volume of liquid in module when the temperature increases, increase buffer space, the pressure that expansion of liquids is produced is no more than the pressure that module or frame can be born, thus guarantee module frame is not destroyed.
But due to liquid cooled module and frame dimensions restriction, and the release of fluid pressure needs larger extending space, it is obviously lower on volume utilization that the piston of single-stage adds piston cylinder, cannot meet technical requirements.
Summary of the invention
In order to solve technical problem existing in background technique, the invention provides a kind of multistage retractable earth pressure release damping device, this multistage retractable earth pressure release damping device have employed the mode of multi-stage expansion, namely space is saved, can bear larger fluid pressure again, structure is simple, practicability is high.
Concrete technical solution of the present invention is as follows:
This multistage retractable earth pressure release damping device comprises sleeve and end cap, sleeve is provided with liquid-inlet, piston and at least two-stage piston cylinder is provided with in described sleeve, liquid-inlet is corresponding with piston position, as piston and the second piston cylinder interference fit of the first order, be provided with spring in the cavity formed between piston and second piston cylinder, liquid-driving piston overpowers spring resistance moves in second piston cylinder; Be provided with for mounting spring near liquid-inlet one end and prevent the step that second piston cylinder is deviate from three grades of piston cylinders outside described second piston cylinder, second piston cylinder is as the piston of three grades of piston cylinders, be provided with spring between second piston cylinder and three grades of piston cylinders, liquid-driving second piston cylinder against the force of the spring moves in three grades of piston cylinders; If piston cylinder is two-stage, then three grades of piston cylinders are as the piston of sleeve, and structure and second piston cylinder coordinate three grades of piston cylinders identical, if piston cylinder is greater than two-stage, then maximum first stage piston cylinder is as the piston of sleeve, and structure and first stage piston cylinder coordinate second piston cylinder identical.
Above-mentioned piston cylinder is two-stage.
Advantage of the present invention is as follows:
This multistage retractable earth pressure release damping device have employed the mode of multi-stage expansion, and namely save space, can bear larger fluid pressure again, structure is simple, practicability is high.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail:
As shown in Figure 1, this multistage retractable earth pressure release damping device mainly comprises sleeve and end cap, sleeve is provided with liquid-inlet, piston and at least two-stage piston cylinder is provided with in sleeve, the quantity of piston cylinder can consider according to actual liquid Volume Changes, can be set to two-stage, three grades even more, multi-level piston barrel structure all similar, general more options two-stage or three grades in actual job;
Liquid-inlet on above-mentioned sleeve is corresponding with piston position, and as piston and the second piston cylinder interference fit of the first order, be provided with spring in the cavity formed between piston and second piston cylinder, liquid-driving piston overpowers spring resistance moves in second piston cylinder; Be provided with for mounting spring near liquid-inlet one end and prevent the step that second piston cylinder is deviate from three grades of piston cylinders outside second piston cylinder, second piston cylinder is as the piston of three grades of piston cylinders, be provided with spring between second piston cylinder and three grades of piston cylinders, liquid-driving second piston cylinder against the force of the spring moves in three grades of piston cylinders; If piston cylinder is two-stage, then three grades of piston cylinders are as the piston of sleeve, and structure and second piston cylinder coordinate three grades of piston cylinders identical, if piston cylinder is greater than two-stage, then maximum first stage piston cylinder is as the piston of sleeve, and structure and first stage piston cylinder coordinate second piston cylinder identical.
This multistage retractable earth pressure release damping device is fixed in liquid cooled module structural member or frame by sleeve lower end from threaded, piston passes through connecting port and the liquid communication of piston cylinder lower end, when ambient temperature raises, or when the work of inside modules thermal source causes fluid temperature to raise and the fluid pressure of the instantaneous generation of liquid supply equipment increases, promotion piston moves by liquid, concrete action is: pressure is passed to spring and makes spring-compressed by first order piston, piston moves up, liquid storage space in module is increased, thus fluid pressure in release module.
When first order piston reaches maximum compressibility and fluid pressure is still larger, then second level piston cylinder starts the Compress Spring that moves upward, make liquid volume corresponding increase again, until second level piston spring reaches maximum compressibility, now pressure reaches and starts third level piston cylinder, third level piston cylinder moves upward Compress Spring, reaches easily extensible volume maximum.
When temperature reduces, after the corresponding reduction of pressure, under the force of a spring, third level piston cylinder starts to move downward and returns, and after third level piston cylinder restores to the original state, reduces with pressure, corresponding second level piston cylinder, first order piston starts to return, until restore to the original state.The design of spring should be noted when designing and using, make this device to increase step by step and to return.
