One water tank crust is provided, and configuration also coats around the inner water tank 10, and forms a space in inner water tank 10 and 30 of water tank crusts; And the material of water tank crust 30 can adopt galvanized iron sheet, lacquered sheet iron, plastic-blasting iron sheet, stainless steel or plastics etc. as material.
Provide at least one energy to transmit control device 40, each energy transmits control device 40 and has a thickness, and this energy thickness of transmitting control device 40 is greater than the space of 30 of inner water tank 10 and water tank crusts; Therefore; When energy transmits control device 40 and will be embedded in the space of 30 of inner water tank 10 and water tank crusts; Need with energy transmit in the control device 40 phase-change material 50 heating earlier and by solid-state change liquid state into after; Each energy is transmitted control device 40 to be embedded in the space of 30 of inner water tank 10 and water tank crusts; Wherein, it can be that vertical equity and compartment of terrain are embedded in the space of 30 of inner water tank 10 and water tank crusts that each energy transmits control device 40, or horizontal and compartment of terrain is arranged in the heat-insulation layer 20 with the C ring structure; Simultaneously, must keep suitable space between the two ends of the two ends of each energy transmission control device 40 and inner water tank 10 and water tank crust 30.Because liquid can have bigger alteration of form, make energy transmit control device 40 and can fully be attached between inner water tank 10 and the water tank crust 30, and contact with inner water tank 10 and water tank crust 30.In addition, all keep suitable space between the two ends of transmitting control device 40 because of each energy and the two ends of inner water tank 10 and water tank crust 30,, avoid obstruction so favourable foam material is mobile.And energy transmits the purpose that control device 40 must contact with inner water tank 10 and water tank crust 30, then is in order to let heat energy conducted to outside the water tank crust 30 by inner water tank 10, therefore must to be in contact with one another.
Inject a foam material between inner water tank 10 and water tank crust 30.Be that a foam material is injected between inner water tank 10 and the water tank crust 30; Make foam material to transmit the space that is kept around the control device 40 and fill the space between inner water tank 10 and the water tank crust 30 by energy; Just transmit control device 40 with energy and form heat-insulation layer 20, the material of foam material can adopt polyurethane, polystyrene, rock wool or mineral wool etc.
Next, disclose another embodiment of preparation method of the present invention's excessive heating prevention thermal insulation water tank again.A kind of preparation method of excessive heating prevention thermal insulation water tank, its step is following:
One inner water tank is provided, and inner water tank 10 can form the space of a capacity, and the material of inner water tank 10 can adopt enamel inner container, inner steel-plastic container, stainless steel inner container or engineering plastics etc. as material.
Provide at least one energy to transmit control device 40, each energy transmits control device 40 and has a thickness; Then; Each energy is transmitted control device 40 to be disposed at outside the inner water tank 10 on the wall; And it is to be embedded on inner water tank 10 with vertical equity and compartment of terrain that each energy transmits control device 40; Simultaneously, must keep suitable space between the two ends of the two ends of each energy transmission control device 40 and inner water tank 10.
One water tank crust is provided, around its configuration and coating inner water tank 10, and in inner water tank 10 and 30 formation of water tank crust, one space; And the material of water tank crust 30 can adopt galvanized iron sheet, lacquered sheet iron, plastic-blasting iron sheet, stainless steel or plastics etc. as material.
Inject a foam material between inner water tank 10 and water tank crust 30.Be that a foam material is injected between inner water tank 10 and the water tank crust 30; Make foam material to transmit the space that is kept around the control device 40 and fill the space between inner water tank 10 and the water tank crust 30 by energy; Just transmit control device 40 with energy and form heat-insulation layer 20, the material of foam material can adopt polyurethane, polystyrene, rock wool or mineral wool etc.
Because the thickness that the present invention's energy transmits control device 40 is greater than the space of 30 of inner water tank 10 and water tank crusts; Therefore, after energy transmits control device 40 and is embedded in inner water tank 10 and water tank crust 30, can fully be attached between inner water tank 10 and the water tank crust 30 and and contact with inner water tank 10 and water tank crust 30.In addition, all keep suitable space between the two ends of transmitting control device 40 because of each energy and the two ends of inner water tank 10 and water tank crust 30,, avoid obstruction so favourable foam material is mobile.And energy transmits the purpose that control device 40 must contact with inner water tank 10 and water tank crust 30, then is in order to let heat energy conducted to outside the water tank crust 30 by inner water tank 10, therefore must to be in contact with one another.
Energy transmits the preparation method of control device
Next, the present invention further discloses one of the preparation method embodiment that energy transmits control device.
A kind of energy transmits the preparation method of control device, and its step is following:
One phase-change material 50 is provided, with 50 heating of this phase-change material and make its by solid-state change into liquid state after, again that this is liquid phase-change material 50 is with in the wrap 403 in a certain amount of the pouring into, and the material of inflation bar also can be plastic-aluminum combined material.
