Abstract

The utility model relates to a portable heating refrigeration case of car vehicle-mounted, its characterized in that: the heating and refrigerating box comprises a heat preservation box body, a heating module and a refrigerating module, wherein the heating module and the refrigerating module are respectively 5, the bottom surface is 1, the four side surfaces are respectively 1, and the modules are fixedly connected through clamping grooves. This portable heating refrigeration case of car vehicle-mounted simple structure, the batch production of being convenient for, safety ring protects in addition, can dismantle, and convenient to carry has solved not have food heat preservation or cold-stored facility on the car and has led to the fact inconvenient problem at the long-distance in-process of traveling.

Description

Automobile is with car portable heating refrigeration heat case

Technical field: the utility model belongs to the heat storage and cold accumulation technical field, relates to a kind of automobile with car portable heating refrigeration heat case.

Background technology: the heat storage and cold accumulation technology is widely used in each link of generation, transportation and use of energy.Technical development recent years is very fast, obtains huge achievement, mainly concentrates on: aspects such as phase-change heat transfer analysis, system capacity balance, intensified heat transfer method.Boundless in heating, air-conditioning and field of heat exchangers application prospect.Their basic principle is: phase-change material discharges latent heat at process of setting, and phase-change material absorbs latent heat in melting process.The application on automobile at present of this technology mainly aspect air-conditioning, use aspect the insulation of food or the refrigeration less; At present general automobile is not used in the facility of food insulation or refrigeration basically, in long-distance driving process, especially during the broiling summer or cold winter during long-distance running, seems very inconvenient.

Summary of the invention: the utility model is the problem that brings inconvenience in long-distance driving process in order to solve the facility that does not have food insulation or refrigeration on the automobile, a kind of automobile is proposed with car portable heating refrigeration heat case, it is characterized in that: described heating and cooling case comprises insulation casing, heating module, refrigeration module, each 5 of described heating module, refrigeration modules, 1 of bottom surface, each 1 of four side, each module is connected and fixed by draw-in groove.This automobile is simple with the portable heating and cooling box structure of car, is convenient to produce in batches, and safety and environmental protection, detachable, easy to carry.

Description of drawings: Fig. 1 is the structural representation of the utility model automobile with car portable heating refrigeration heat case.

The specific embodiment: as Fig. 1, Fig. 2, shown in Figure 3, this automobile comprises insulation casing 6, heating or refrigeration module 1 with car portable heating refrigeration heat case, and wherein heating module, refrigeration module are each 5: 1 of bottom surface, each 1 of four side; Between each side, be connected and fixed by tongue and groove 13,14 between side and the bottom surface, can be for convenience detach, around the module of bottom surface tongue and groove is arranged, there is tongue and groove on side modules three limits.The shell 2 of casing 1 is used polypropylene plastics products, and the thin stainless steel flitch of inwall 4 usefulness is made, and the middle polyurethane expanded material 3 of filling is sealed by tongue and groove between loam cake and lower box.

As shown in Figure 2, refrigeration module 7 is made up of shell 8 and refrigerant 9, and shell 8 usefulness stainless steel materials are made; Refrigerant 9 makes water, ethanol, sodium chloride, potassium chloride mixed solution, its freezing point is-3 ℃, and latent heat of phase change is 300KJ/kg, and refrigerant is a liquid phase under the normal temperature, make it be transformed into solid phase with the domestic refrigerator refrigeration during use, utilize its latent heat of phase change to realize the refrigeration of article such as beverage.As shown in Figure 3, heating module 10 is made up of shell 11 and heat transfer medium 12, and shell 11 usefulness makrolon materials are made; Heat transfer medium 12 adopts No. 90 its melt drop temperature of microwax to be not less than 87 ℃, and latent heat of phase change is at 203～300KJ/kg, and heat transfer medium 12 microwaxes are solid phase under the normal temperature, makes it be transformed into liquid phase with the micro-wave oven heating during use, utilizes its latent heat of phase change to be insulations such as food.

Automobile is to use the incubator of phase-change material with car portable heating refrigeration heat case, and is easy to carry.During the heating module heating, can provide energy by warming-up devices such as household microwave oven or instrument, phase-change material is produced by being solid to liquid phase transition, the form of heat with latent heat is stored in the phase-change material, during use in the heating module phase transformation come out to take place by liquid phase the form of heat with latent heat to be discharged to solid transformation.During the refrigeration module refrigeration, can be lower than the refrigeration facility of phase-change material freezing point, make phase-change material be transformed into solid phase gradually, the form of cold with latent heat is stored in the phase-change material by liquid phase by environment temperatures such as domestic refrigerators; During use in the incubator environment temperature be higher than the phase-change material freezing point, phase-change material changes into liquid phase gradually by solid phase, and cold is discharged with the latent heat form.Therefore this automobile is with the portable heating and cooling case of car safety and environmental protection, and simple in structure, especially is fit to produce in batches.
