Description
Technical field
The present invention relates to a kind of bascule, be particularly related to a kind of internal and external pressure balance device of cold-storage heat exchanger, it belongs to the cold-storage technical field, be installed on the top of cold-storage heat exchanger, play the internal and external pressure balance effect of cold-storage heat exchanger, prevent from the thermal cycle process, to cause the deformation and failure of interchanger because of its volume expands with heat and contract with cold because of the agent for storage of coldness in the heat exchanger.
Background technology
General cold-storage heat exchanger is that inside is placed with phase-change material for cold storage, and it has the function that agent for storage of coldness and external environment condition are carried out heat exchange, is a closed container.
In the thermal cycle process, phase-change material for cold storage from liquid state after cooling becomes solid phase, volume can increase 10%, and by solid phase after cooling becomes solid phase, volume can increase 10%, and by solid phase after heating becomes liquid state, volume can dwindle 10%, so, because of expanding with heat and contract with cold, its volume in the thermal cycle process of the agent for storage of coldness in the heat exchanger causes the deformation and failure of interchanger in order to prevent at the cold-storage heat exchanger that uses at present both at home and abroad, when the can cool storage material, reserve enough spaces, the volume of can cool storage material is generally about 75% of cold-storage heat exchanger internal volume.
And after cold-storage heat exchanger adorned pressure equaliser of the present invention, can keep automatically because of the internal and external pressure balance in its volume process of expansion and contraction in the thermal cycle process of the agent for storage of coldness in the heat exchanger, therefore, when the can cool storage material, the space of reserving is much smaller, and the volume of can cool storage material can be about 85% of cold-storage heat exchanger internal volume.Promptly increase the capacity of cool storage material, can avoid the deformation and failure of interchanger again.
So the internal and external pressure balance device that is necessary to design a kind of new cold-storage heat exchanger remedies these defectives of known techniques.
Summary of the invention
The technical problem to be solved in the present invention is to overcome many deficiencies of the prior art, provide a kind of simple in structure, easy to use, the cold-storage effect is good, its internal and external pressure balance effect can prevent to cause the deformation and failure of cold-storage heat exchanger because of its volume expands with heat and contract with cold because of the agent for storage of coldness in the cold-storage heat exchanger in the thermal cycle process.
In order to achieve the above object, the invention provides a kind of internal and external pressure balance device of cold-storage heat exchanger, it comprises agent for storage of coldness, cold-storage heat exchanger and pressure equaliser, described pressure equaliser comprises intake valve group and gas bleeder valve group, described intake valve group comprises first valve body, air inlet, first spring, first steel ball, first clamp nut and first gasket seal, described gas bleeder valve group comprises second valve body, leakage port, second spring, second steel ball, second clamp nut and second gasket seal, described intake valve group and described gas bleeder valve group are installed in the top of described cold-storage heat exchanger; Described agent for storage of coldness places in the described cold-storage heat exchanger.
The internal and external pressure balance device of a kind of cold-storage heat exchanger provided by the invention, described first clamp nut closely are set in described first gasket seal top, and described second clamp nut closely is set in described second gasket seal top.
The internal and external pressure balance device of a kind of cold-storage heat exchanger provided by the invention, described air inlet is located in the described first steel ball activity, and described first steel ball and the described first spring butt; Described leakage port is located in the described second steel ball activity, and described second steel ball and the described second spring butt.
By mutually combining of above-mentioned each element, the phase-change material for cold storage of depositing in the cold-storage heat exchanger is in the cold cycling process, and after cooling became solid phase, volume can increase about 8% from liquid state, at this moment, the gas at cold-storage heat exchanger top backs down steel ball because of being compressed the pressure rising and overcoming gas bleeder valve group spring force, is excreted to the outside, at this moment, external and internal pressure restores balance, and steel ball is under the effect of spring force, and return seals leakage port.And by solid phase after heating becomes liquid state, volume can dwindle 8%, at this moment, the cold-storage heat exchanger headroom causes vacuum because of expansion, and outside atmosphere overcomes intake valve group spring force, backs down steel ball and enters interchanger inside, at this moment, external and internal pressure restores balance, and steel ball is under the effect of spring force, and return seals air inlet.The present invention is simple in structure, easy to use, the cold-storage effect is good, can prevent to cause the deformation and failure of cold-storage heat exchanger because of its volume expands with heat and contract with cold because of the agent for storage of coldness in the cold-storage heat exchanger in the thermal cycle process.
