RU16715U1 - MINI REFRIGERATOR FOR VOLGA CAR - Google Patents

Abstract

A mini-refrigerator for a car, comprising a case equipped with a thermoelectric unit made using a thermoelectric module, to a hot junction of which a radiator cooled by a fan is attached, as well as a cover, a facing panel and a power supply unit from the vehicle electrical circuit, characterized in that it is installed inside the pharmacy box on the panel under the rear window of the car, and the cold junction of the thermoelectric module is attached to the metal plate, which is the accumulator of cold inside a brary box having a thermal insulation, which increases the efficiency of the mini-cooler, wherein the power supply includes a switch, which provides two operating modes: a cooling mode and a cold keeping mode.

Description

MINI REFRIGERATOR for VOLGA CAR

The utility model relates to refrigerators for vehicles, and more precisely to mini-refrigerators for the Volga models 31029, 3102, 3110, 3111.

Known mini-refrigerators on thermal modules for cooling poor products and filaments used in automobiles (mini-refrigerators manufactured by Mikroholod LLC, Russia, Nizhny Novgorod). These well-known refrigerators contain a housing equipped with a thermoelectric unit made using a thermoelectric module, to the hot junction of which a radiator cooled by a fan is attached, there is also a cover, a cover panel and a power supply unit from the vehicle electrical circuit.

Although these well-known mini-refrigerators provide reliable operation, create environmental friendliness due to the lack of freon, are silent, and are resistant to vibrations, they create inconvenience for the driver - you need to find a place to install them, and they are not used to store a first-aid kit, which is an essential part of the car.

The technical result of the proposed utility model of a mini-refrigerator is to create convenience for a car driver and the possibility of using this mini-refrigerator for storing a first-aid kit, i.e. for storing medicines, as well as perishable foods and drinks.

The technical result is achieved by the fact that in a utility model of a mini-refrigerator for a car comprising a housing equipped with a thermoelectric unit made in the form of a thermoelectric module, a radiator cooled by a fan is attached to the hot junction, and

the cover, facing panel, and the power supply unit from the vehicle’s electrical circuit, it is new that the mini-refrigerator is installed inside the pharmacy box on the panel under the rear window of the car, and the cold junction of the thermoelectric module is attached to the metal plate, which is the cold accumulator inside the pharmacy box, which is insulated , increasing the efficiency of the mini-refrigerator, while the power supply contains a switch that provides two modes of operation: cooling mode and the mode of maintaining the cold.

In the future, a utility model will be described in detail in the description with reference to the accompanying drawings, in which:

FIG. 1 depicts the proposed mini-refrigerator on thermoelectric modules, a General view, in section, with a break;

FIG. 2 - thermoelectric unit used in the proposed mini-refrigerator.

The proposed utility model of a mini-refrigerator for a car “Volga contains a housing 1 (Fig. 1), equipped with a thermoelectric unit 2, a cover 3, a facing panel 4 and a power supply unit 5 from the vehicle’s electrical circuit, having a positively charged power wire 6 and a negatively charged power wire 7 voltage 12 - 14 V. Thermoelectric unit 2 (Fig. 2) is made in the form of a thermoelectric module 8, to the hot junction 9 which is attached a radiator 10 cooled by fan I. The cold junction 12 of this module 8 is attached to m the metallic plate 13 (FIG. 1), a cold accumulator in pharmacy box (not shown) mounted on the panel below the rear glass of a vehicle. Inside the cladding panel 4 there is a heater in the form of a mounting foam 14, and under the cover.

seal in the form of a plate 15 of penofol and a seal in the form of decorative sheets 16 of polyethylene foam. The facing panel 4 is mounted on the posts 17 with the screw 18 and the washer 19. Between the decorative sheets 16 and the insulation - mounting foam 14, a sealing gasket 20 is installed.

The power supply unit 5 includes a switch 21, which provides two operating modes: in cooling mode, in which the power consumed by the mini-refrigerator is 45 W, and in the mode of maintaining the cold, in which the power consumed by the mini-refrigerator is 20 W.

The principle of operation of the mini-refrigerator is based on the Peltier effect. Thermoelectric module 8 was used as a heat - cold converter. The volume of the refrigerating chamber inside the box is 6 dm. This refrigerator can be used as a first aid kit, i.e. store drugs, perishable foods and drinks in it.

The temperature inside the pharmacy box is from 3 to 5 ° C at an ambient temperature of up to 30 ° C and is reached after 25 - 30 minutes. The pharmacy box has thermal insulation that increases the efficiency of the mini-refrigerator.
