Description
Technical field
The invention belongs to refrigerating systems, and in particular to a kind of novel heat insulation refrigerating chamber.
Background technology
Cold-storage insulation equipment is widely used in the industries such as chemical industry, medicine, food, wherein it is most in food service industry application, greatly
Amount meat vegetables and fruits are required for cold-storage insulation to preserve.Due to the backwardness of cold-storage insulation technology, there are a large amount of vegetables and fruit in China every year
Product rot to damage in storage, and loss is surprising.
Due to only placing thermal insulation material in peripheral insulating layer, such as heat-preservation cotton etc. causes do not having existing refrigerating chamber
In the case of having low-temperature receiver, quickly, heat insulation effect declines for heating in refrigerating chamber, and the damage of a large amount of chilled goods is easily caused to rot.
Invention content
Goal of the invention：In view of the deficiencies of the prior art, the present invention intends to provide a kind of of low cost, energy consumption
Small, good heat insulating, the heat preservation temperature keeping room that cruising ability is strong and heat exchange efficiency is high.The temperature keeping room passes through foam gold
Belong to structure insulating layer frame, internal filled composite phase-change material, the energy storage in cold storage procedure, works as refrigeration using composite phase-change material
Case can slowly be absorbed heat in the insulating process of no extraneous low-temperature receiver by phase-changing energy storage material, to persistently to the food in refrigerating box
Product are kept the temperature, and substantially increase heat preservation cruising ability, reduce operating cost.
Technical solution：To achieve the goals above, novel heat insulation refrigerating chamber as described herein includes refrigerating chamber babinet, protects
Warm layer and filled layer, the insulating layer are covered in refrigeration chamber surface, and the filled layer is filled in inside insulating layer, the insulating layer
For foam metal layer, the filled layer is phase-change material layers or composite phase-change material layer.
Wherein, the refrigerating chamber babinet is polyhedron.
Further, the refrigerating chamber babinet is hexahedron, six faces outer surface of the insulating layer and refrigerating chamber babinet
To be in direct contact and closely attaching, better heat transfer effect is generated.
It builds to be formed preferably, the foam metal layer is porous media foamed metal structures, model KX2020 is more
Hole dielectric foam metal structure is bought from Kunshan Kuang Xun Electronics Co., Ltd.s, and 90% or more foam copper is reached using porosity,
Heat transfer coefficient is more than 6W/ (m2* k), porous foam copper is video card and the optimal material of CPU heat dissipations, is highly suitable as heat conduction and dissipates
Hot material；Solid-liquid material can be filled in porous media foamed metal structures.
Insulating layer is exactly closely to be attached to box outer surface, is in direct contact.Insulating layer is by porous media foam metal knot
Structure is built, and has many holes inside porous media foam metal, and composite phase-change material, phase are filled in these holes
Become material or composite phase-change material in porous media foam metal can free phase transformation, and phase is improved by foam metal
Become exchange capability of heat and accelerates phase transition process.
Preferably, the phase-change material layers are paraffin layer；The composite phase-change material layer is the bodies such as paraffin and lauric acid
Product mixed layer.Wherein, the paraffin layer that phase-change material layers use is the special paraffin of phase-changing energy storage material, is phase transition temperature in 20-80
DEG C special wax, model F25 buys from Shanghai Joule Wax Industry Co., Ltd, and paraffin purity is high, and phase transition temperature is accurate, and heat content is high,
It is non-toxic and tasteless, white；And paraffin is bought with the lauric acid in the isometric mixed layer of lauric acid from Shanghai De Mao Chemical Co., Ltd.s,
White needle-like crystals, micro- have oreodaphene fragrance, not soluble in water, dissolves in the organic solvents such as methanol.
Advantageous effect：Compared with prior art, the invention has the advantages that：
The novel heat insulation refrigerating chamber of the present invention builds insulating layer frame by porous media foamed metal structures, and inside is filled out
It fills phase-change material or composite phase-change material forms filled layer, the energy storage in cold storage procedure using phase-change material, when refrigerating box exists
Without can slowly being absorbed heat by phase-changing energy storage material in the insulating process of extraneous low-temperature receiver, it ensure that the heat-insulating property of refrigerating box and continuing
Boat ability, foamed metal structures improve the energy storage efficiency and heat exchange property of phase-change material.
Advantage of the invention is that solving, refrigerating chamber insulating efficiency is low, keeps the temperature the problem of cruising ability difference, while energy consumption
It is small, processing cost is low and heat exchange efficiency is high.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Specific implementation mode
The invention will be further described with reference to the accompanying drawings and examples.
