Abstract
The utility model discloses a kind of car refrigerator, comprise casing, described casing comprises thermal insulation layer and heat-insulation layer, described heat-insulation layer is an annular hollow container, in described heat-insulation layer, be provided with heat insulation liquid, the upper end of described heat-insulation layer is provided with a liquid injection port, and described liquid injection port is connected with the hollow structure of described heat-insulation layer, and the material of described heat-insulation layer is metal.Car refrigerator of the present utility model can be stored cold air, and the cooling beverage of newly putting into fast, reduces the variation of temperature in car refrigerator.
Description
Technical field
The utility model relates to vehicle-mounted apparatus field, specifically relates to a kind of car refrigerator.
Background technology
Existing car refrigerator volume is little, and the cold air that its inside holds is also few.In the process using, newly put into the article such as beverage and can make the temperature of whole car refrigerator sharply increase, put into new beverage all needs to wait considerable time to go cooling at every turn.Its main cause is that car refrigerator volume is little, and the cold air that its inside holds is also few.
Utility model content
(1) technical problem that will solve
The deficiency existing for prior art, the utility model provides one can store cold air, fast the cooling car refrigerator of newly putting into beverage.
(2) technical scheme
For achieving the above object, the utility model provides a kind of car refrigerator, comprise casing, described casing comprises thermal insulation layer and heat-insulation layer, described heat-insulation layer is an annular hollow container, in described heat-insulation layer, is provided with heat insulation liquid, and the upper end of described heat-insulation layer is provided with a liquid injection port, described liquid injection port is connected with the hollow structure of described heat-insulation layer, and the material of described heat-insulation layer is metal.
Further, described heat insulation liquid is sodium chloride solution.
Further, the mass fraction of the solute of described sodium chloride solution is 6% to 10%.
Further, the material of described heat-insulation layer is stainless steel.
Further, the structure of described thermal insulation layer is followed successively by plastics, sponge, plastics from outside to inside.
(3) beneficial effect
The utility model car refrigerator can be stored cold air, and the cooling beverage of newly putting into fast, reduces the variation of temperature in car refrigerator.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model car refrigerator top view direction;
Fig. 2 is the structural representation of the utility model car refrigerator stereogram direction;
Fig. 3 is the structural texture schematic diagram of the utility model car refrigerator heat-insulation layer.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The structure of a kind of car refrigerator of the present utility model as shown in Figure 1, Figure 2 and Figure 3, comprise casing, described casing comprises thermal insulation layer 2 and heat-insulation layer 1, described heat-insulation layer 1 is an annular hollow container, in described heat-insulation layer 1, be provided with heat insulation liquid, the upper end of described heat-insulation layer 1 is provided with a liquid injection port 3, and described liquid injection port 3 is connected with the hollow structure of described heat-insulation layer 1, and the material of described heat-insulation layer 1 is metal.Heat-insulation layer 1 selects metal to be because metal has good thermal conductivity, can absorb fast the heat of newly putting into beverage.Heat insulation liquid can store a large amount of cold air.
Wherein, described heat insulation liquid is sodium chloride solution, and the mass fraction of the solute of described sodium chloride solution is 6% to 10%.Adding sodium solution is as heat insulation liquid, be because sodium chloride solution has lower fusing point on the one hand, but the solute mass fraction of sodium chloride should be not too high yet, and mass fraction is too high easily occurs that sodium chloride part separates out.The heat capacity ratio of water is sizable, but the freezing point of water is too high, adds sodium chloride can reduce the freezing point of water in water.
As optimization, the material of described heat-insulation layer 1 is stainless steel, due to heat-insulation layer 1 in-built be sodium chloride solution, in order to prevent the corrosion of heat-insulation layer 1, described heat-insulation layer 1 material select the required resistant material of selecting.Also on heat-insulation layer 1, spelter is being set if desired, for preventing the material oxidation of heat-insulation layer 1.
In addition the structure of described thermal insulation layer is followed successively by plastics 6, sponge 4, plastics 5 from outside to inside.This structure has good effect of heat insulation.
The beneficial effects of the utility model: can store cold air, the cooling beverage of newly putting into fast, reduces the variation of temperature in car refrigerator.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
