Abstract

The utility model discloses an electronic air conditioner, which is composed of an air inlet, a fan and a motor, a change of cooler, a heat insulation layer, a cold / hot air changeover switch, a speed regulation knob, a casing, a radiator, a heat protector, a radiating fan, a thermoelectric cooling assembly, an insulation damping material and an air outlet, etc. The utility model is characterized in that the thermoelectric cooling assembly is a refrigerating or heating device. The function of the electronic air conditioner is used for refrigerating and heating. The electronic air conditioner can be used in various driving cabs of automobiles, tanks, armored cars and the locomotive. The utility model has the advantages of not polluting the environment.

Description

The electronics A/C

The utility model relates to A/C, particularly relates to the electronics A/C.

What adopt in the known automobile is the A/C of refrigerant with fluorine Lyons, and its cost is high, and easily leak, contaminated environment.

The purpose of this utility model is to provide a kind of filling refrigerant, free of contamination electronics A/C of need not.

Electronics A/C of the present utility model is made up of ventilation inlet, fan-motor D, cold-exchange, heat-insulation layer, wire fuse, cold and hot wind change-over swith K, speed governing turn-knob, shell, air outlet, connecting screw rod, connection small screw, bolt of rear end plate, radiator, thermal protector J1 and J2, radiator fan, thermoelectric cooling module, grille guard and heat-insulating damp material.It is characterized in that with the thermoelectric cooling module being refrigeration or heater element.Thermoelectric cooling module is two galvanic couples that different (N type and P type) semi-conducting material is connected into the metal flow deflector.After connecting direct supply, energy just takes place thermoelectric cooling module shifts, and promptly its electric energy is transformed into heat energy, and thermoelectric cooling module one end is turned cold (heat absorption), other end heating and emit heat.Its function is promptly can refrigeration, also can heat.The electronics A/C can adopt the thermoelectric cooling module 1-8 sheet of TEC1, TEC2 type respectively according to the needs of its purposes, and in parallel, series connection is used and all can.Adopt the 3-48V direct supply, its electric current is 10-80A.The function conversion of its refrigeration or heating is by cold and hot wind change-over swith K control.As long as cold and hot wind change-over swith K-through turned position (change sense of current), then the electronics A/C promptly is converted to heating (perhaps refrigeration) by refrigeration (perhaps heating); Ventilation inlet and air outlet are horn-like; The fan of fan-motor D adopts centrifugal flow fan, and motor D is the small-sized DC buncher, and cold-exchange and radiator are welded with electric soldering iron after all adopting aluminium section bar or adopting red copper sheet machine-shaping; The heat-insulation layer material is expandable polystyrene or PAPI, and shell adopts polypropylene or sheet iron machine-shaping; Thermal protector J ₁And J ₂Be thermal relay, prevent too high and " burning " the bad thermoelectric cooling module of temperature with it; It is cold that radiator fan adopts prerotator directly to blow into capable high wind; Heat-insulating damp material is the soft foam of high-density and high-temperature-resistant; Grille guard is a metal gauze.The outlet and inlet of this electronics A/C is the room air circulation.This electronics A/C uses in the operator's compartment of automobile (comprising diesel-powered vehicle), wheel crane, tank, armored motor car and diesel locomotive in various models, electric locomotive.Be fixed on the position of the positive front lower place of copilot in the various vehicle cabs, perhaps be installed on the support of setting up on the vehicle motor next door.

The advantage of electronics A/C of the present utility model is need not the refrigerating machine system, also just need not to fill refrigerant naturally.So electronics A/C no leak, pollution-free, noiseless, nothing wearing and tearing, friction, and volume is little, in light weight, cost is low, the life-span is long, uses reliable, easy to maintenance.

Fig. 1 is that electronics A/C structure is overlooked cross-sectional schematic;

Fig. 2 is the organigram of cold-exchange or radiator;

Fig. 3 is electronics A/C electric appliance circuits figure.

Most preferred embodiment: the electronics A/C is by ventilation inlet (1), fan-motor D (2), cold-exchange (3), heat-insulation layer (4), wire fuse (5), cold and hot wind change-over swith K (6), speed governing turn-knob (7), shell (8), air outlet (9), connecting screw rod (10), connection small screw (11), bolt of rear end plate (12), radiator (13), thermal protector J ₁And J ₂(14), radiator fan (15), thermoelectric cooling module (16), grille guard (17) and heat-insulating damp material (18) are formed.Adopt 12V direct supply (01), electric current is 32A; Adopt (16) 4 of TEC1 type thermoelectric cooling modules; The fan of fan-motor D (2) is a centrifugal flow fan, and motor D is dc micro-motor (CCW); Speed governing turn-knob (7) is adjusted the resistance of resistance R in 0～10K Ω scope, to control motor speed by rated speed of rotation to 0; The radiating gill (130) of cold-exchange (3) and radiator (13) be red copper sheet according to the shape blanking after, be welded with electric soldering iron, it forms thermal protector J by radiating gill substrate (131) and radiating gill blade (132) ₁And J ₂(14) adopt 70 ℃ of thermal relays of JUC closed type; Shell (8) adopts polypropylene duroplasts forming process to make; Radiator fan (15) adopts FZY-D type motor.Heat-insulation layer (4) is the expandability polystyrene.The electronics A/C of present embodiment uses in the Shanghai-Santana driver's cab of sedan, is installed on the position of the positive front lower place of copilot in its operator's compartment.

Claims

1, a kind of electronics A/C of being made up of ventilation inlet, fan-motor, cold-exchange, heat-insulation layer, wire fuse, cold and hot wind change-over swith, speed governing turn-knob, radiator, thermal protector, thermoelectric cooling module, heat-insulating damp material, radiator fan, grille guard, air outlet and shell is characterized in that thermoelectric cooling module is refrigeration or heater element.
