Description
Technical field
The utility model relates to a kind of thermal insulation thermal insulation board, in particular, relates to a kind of thermal insulation thermal insulation board with cold-storage layer or recuperation layer and vacuum heat-insulating layer.
Background technique
For the low temperature environment space, as refrigerator, freezer, cold storage cabinet etc., owing to have the temperature difference with the external world, outside heat can constantly be imported low temperature space into.The refrigeration system of keeping low temperature space can start when the cabinet interior space temperature is higher than setting temperature, shuts down when being lower than setting temperature.Its result can make the temperature in the cold storage cabinet that bigger fluctuation is arranged, and this fluctuation can cause that cabinet interior store food or biological products owing to the different weightlessnesses that produce of the amount of freezing under different temperatures, cause food or biological products quality to descend.In order to address the above problem, have and adopt the technology reduce the temperature difference that cold storage cabinet sets, but result's frequent startup-shutdown that is refrigeration system, shortened the working life of refrigeration system.And for the hot environment space, as water heater, heater etc., owing to have the temperature difference with the external world, internal heat can constantly pass in the external environment condition.For this reason, insulation and the heat-shielding performance that is used for the thermal insulation thermal insulation board of above-mentioned refrigeration or heating plant is the key problem in technology that influences heat insulating effect.Existing thermal insulation thermal insulation board adopts loose fill type insulant usually, as polyurethane, polystyrene material or the glass wool material of foaming since thermal conductivity to be limited in refrigeration and the heating plant thickness that uses bigger.For example, generally for-18 ℃ of freezers, need the thickness should be greater than 100mm when doing thermal-protective coating with polyurethane foam material, its result makes equipment volume bigger, seems heavy.Be subjected to taking up an area of the restriction in space for some equipment, can only reduce the thickness of thermal insulation thermal insulation board, the result has the part heat or cold runs off by thermal insulation thermal insulation board, makes that the energy consumption of equipment is bigger.
The model utility content
The utility model is in order to overcome deficiency of the prior art, a kind of coefficient of heat transfer that can reduce thermal insulation thermal insulation board to be provided, thereby reduces the thickness of insulation layer, reduces refrigeration or heating space inside temperature gradient, the thermal insulation thermal insulation board of energy saving.
The utility model is achieved through the following technical solutions:
A kind of thermal insulation thermal insulation board comprises the bulk material thermal insulation layer, it is characterized in that, also comprises the accumulation of energy layer, is provided with vacuum heat-insulating layer between described accumulation of energy layer and the bulk material thermal insulation layer.
Described bulk material thermal insulation layer is any in polyurethane, organic insulation material, the inorganic heat insulation material.
Energy-accumulation material in the described accumulation of energy layer is any in oil, water, ethylene glycol, glycerine, ethanol, the dichloromethane.The sheet material that is used to surround energy-accumulation material is stainless steel.
The material of wrapped vacuum thermal-protective coating is metallic material or nonmetallic material.
The utlity model has following technique effect:
1. it is energy-conservation: when thermal insulation thermal insulation board of the present utility model is used for refrigeration or heating plant system insulation, can reduce the coefficient of heat transfer of insulation layer, reduce owing to the thermal loss that thermal insulation layer absorbs heat or heat radiation causes, effectively reduce system's on-off frequency, reach purpose of energy saving.
2. reduce the refrigeration space temperature gradient and the temperature difference: the accumulation of energy layer in the thermal insulation thermal insulation board of the present utility model, can make the temperature gradient of refrigeration or heating space less, make the article in inner any place or fluid temperature even.In refrigeration system startup-shutdown process, can effectively reduce the temperature variation of depositing article, to reduce the dehydration loss of food.
3. saving space: use thermal insulation thermal insulation board of the present utility model can reduce the total thickness of thermal insulation layer, save the occupation of land space of refrigeration or heating equipment.
Description of drawings
Fig. 1 is the structural representation of thermal insulation thermal insulation board of the present utility model.
Among the figure: 1-accumulation of energy layer, 2-vacuum heat-insulating layer, 3-bulk material thermal insulation layer.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is the structural representation of thermal insulation thermal insulation board of the present utility model, comprises bulk material thermal insulation layer 3 and accumulation of energy layer 1, is provided with vacuum heat-insulating layer 2 between described accumulation of energy layer and the bulk material thermal insulation layer.
When refrigeration or heating equipment cooling or heating space, the accumulation of energy layer also is cooled or heats, when stopping cooling or heating, accumulation of energy layer 1 is used to overcome because the thermal loss that the bulk material thermal insulation layer conducts heat and causes plays storing energy simultaneously, guarantees that the inner space temperature acts on uniformly.Vacuum heat-insulating layer 2, bulk material thermal insulation layer 3 play the purpose of insulation.
Energy-accumulation material in the accumulation of energy layer 1 is used for cold-storage or accumulation of heat, can be solid, also can be liquid.Externally do not dispel the heat in the inner space or cold scattering is a principle satisfying, and general thickness is 10-50mm.Can be organic substance, also can be inorganic matter.Can be the material that phase transformation is arranged, also can be the material of no phase transformation.As oil, water, ethylene glycol, glycerine, ethanol, dichloromethane etc.Sheet material in order to the support energy-accumulation material can be stainless steel or other metallic material, also can be nonmetallic material.
The material of wrapped vacuum thermal-protective coating 2 can be a metallic material, also can be nonmetallic material, and the thickness of vacuum heat-insulating layer is unrestricted, and general vacuum section is the smaller the better.
Bulk material thermal insulation layer 3 can be polyurethane or other organic insulation material, inorganic heat insulation material, and its thickness is unrestricted.
Although with reference to embodiment to disclosed relate to a kind of thermal insulation thermal insulation board capable special description, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
