Abstract
The utility model discloses a heat-insulation box additionally provided with vacuum glass tubes in a foaming layer, relating to a heat-insulation water box. The heat-insulation box comprises a shell and a liner, wherein a plurality of vacuum tubes are arranged in the foaming layer between the shell and the liner. The vacuum tubes made of glass materials are arranged in the polyurethane foaming layer and are used for replaying partial polyurethane foaming layer, the structure of a heat-insulation material is changed, and therefore, the heat-insulation box effectively insulates heat conduction and the convection of air so that the effect of heat insulation is improved. The experimental data display that in the environment with the temperature of 6-10 DEG C, after the water with the temperature of 50 DEG C is saved in the conventional polyurethane foaming heat-insulation water box for 24 hours, the temperature of the water is 40-42 DEG C, and the temperature of the water is higher than 48 DEG C after the water is saved in the heat-insulation box for 24 hours.
Description
Technical field
The utility model relates to a kind of insulation can, particularly a kind of insulation casing with polyurethane foam heat-insulation layer that is applicable to solar water heater, refrigerator or refrigerator-freezer etc.
Background technology
The main polyurethane foam technology that adopts of solar water heater, hot water storage tank, refrigerator or refrigerator-freezer insulation realizes insulation by the fine and close aperture that forms in the foamed material foamed solidification process at present, foaming layer density and rate of closed hole decision heat insulation effect quality.The heat insulation effect of polyurethane foam layer own is starkly lower than the vacuum heat-insulating layer heat insulation effect.With the solar water heater is example, and one is 70 hours for its temperature retention time, is in the 6-10 ℃ of environment in ambient temperature, 50 ℃ of water are in conventional polyurethanes foamed heat insulating water tank, 8-10 ℃ of cooling in per 24 hours is restricted the use zone of solar water heater, can not expand to utmost point cold area.And the productive costs of vacuum heat-insulation layer is too high, is difficult for accepting for the user.In the acceptable cost restriction, still there is not solution preferably at present.
Summary of the invention
Technical problem to be solved in the utility model provides the insulation can that installs glass tube with vacuum in a kind of foaming layer additional, can significantly improve polyurethane foam layer heat insulation effect.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: install the insulation can of glass tube with vacuum in a kind of foaming layer additional, comprise housing and inner bag, be provided with many vacuum lamps in the foaming layer between housing and the inner bag.
Described many vacuum lamps are closely arranged.
Between the described many vacuum lamps apart from 0-5cm.
Pressure P≤5.0 * 10 in the described vacuum lamp
-2Pa
Install the insulation can of glass tube with vacuum in a kind of foaming layer that the utility model provides additional; limited and be subjected to the bigger defective of foam process quality influence by changing conventional urethane foam process heat insulation effect; glass evacuated heat preservation technology is combined utilization with the polyurethane foam technology; significantly improve the heat insulation effect of solar water heater, refrigerator or refrigerator-freezer; reduce use amount simultaneously, effectively preserve the ecological environment the polyurethane foam chemical raw material.
The utility model is by inserting the vacuum lamp of glass material in the polyurethane foam layer, replace part polyurethane foam layer with glass tube with vacuum, change the warm material structure, the convection current of effectively isolated heat conduction and air has improved heat insulation effect, and observed data shows, in ambient temperature is in the 6-10 ℃ of environment, 50 ℃ of water are in conventional polyurethanes foamed heat insulating water tank, and temperature is 40-42 ℃ after 24 hours, the utility model after 24 hours temperature be more than 48 ℃.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples: Fig. 1 is a structural representation of the present utility model; Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
In Fig. 1 and Fig. 2, install the insulation can of glass tube with vacuum in a kind of foaming layer additional, comprise housing 1 and inner bag 4, be provided with many vacuum lamps 2 in the foaming layer 3 between housing 1 and the inner bag 4.
Described many vacuum lamps 2 are closely arranged.
Between the described many vacuum lamps 2 apart from 0-5cm.
Pressure P≤5.0 * 10 in the described vacuum lamp 2
-2Pa
Embodiment: increase the vacuum lamp 2 of glass material in original polyurethane foam layer 3 according to certain density, specific practice is: with wall thickness is that 1.6mm, length are that A, caliber are that the glass tube of B is processed into P≤5.0 * 10
-2Pa Vacuum lamp 2 is made in sealing behind the pressure state, then with the spacing arrangement of vacuum lamp 2 according to 0-5cm, distance between the vacuum lamp 2 is too closely impaired because run foul of each other easily in production and transportation, but nearer spacing helps the insulation of insulation can, if do not need the insulation can of long-distance transport, that the spacing between the vacuum lamp 2 can be done is as much as possible little.
By simple and easy mould bases vacuum lamp 2 is lined up the ring skeleton (diameter=inner bag 4 diameters+(housing 1 diameter-inner bag 4 diameters)/2) of certain diameter or the skeleton on plane, integral body is inserted in the foaming space, and then inject the polyurethane foam material and foam, final polyurethane foam material wraps up vacuum lamp 2, forms the heat-insulation layer that polyurethane foam layer 3 adds vacuum lamp 2.After injecting a polyurethane foam material, guarantee in the mixing heat-insulation layer of moulding, certain thickness polyurethane foam layer is all arranged around the glass tube with vacuum, so that fixing glass tube with vacuum and form cushion, prevent the vacuum glass tracheal rupture, make the polyurethane foam layer play well secured and buffering loss prevention effect glass tube.Glass tube length A=attemperater total length-300mm, when A surpassed 1000mm, length should be got A/2; Caliber B=foaming layer 3 thickness-20mm are accustomed to one according to solar power industry and glass product and are defined as 37mm.The diameter of glass tube with vacuum also can be reserved certain cushion layer according to the thickness of heat-insulation layer and determine afterwards.After tested 50 ℃ of water in product of the present invention after 24 hours temperature be more than 48 ℃.
