Description
Technical field
The present invention relates to air conditioning and welding technology field, particularly heat exchanger of air condition and cover copper-aluminum wrapped calandria and U-shaped copper pipe elbow welder and method.
Background technology
In general air-conditioner is arranged on the space of vehicle, office, family etc., and the machine that air is freezed or heats is mainly by compressor; Outdoor heat converter; Expansion valve; The coolant circulating system that critical pieces such as indoor heat converter are formed and by cabinet; Suction, exhaust outlet; Grid; The air guiding; The air circulation system that fan and fan electromotor are formed constitutes.
Air-conditioner can be divided into indoor and outdoor side detachable air conditioner and the incorporated integral air conditioner of indoor and outdoor side apart, and that detachable air conditioner can be divided into again according to the difference of installation form is wall-hanging, ceiling-inserted, cabinet-type etc.Integral air conditioner is divided into the window air conditioner that is arranged on window again and is arranged on the wall hole formula air-conditioner of body of wall the inside.
Existing window air conditioner is as shown in Figure 1: it is by the cabinet 2 that forms appearance; The chassis 3 of parts is installed; Be arranged at the panel 4 of indoor, chassis; Panel 4 downsides are formed with air entry 4a, upside has exhaust outlet 4b; The inboard of panel 4 sets gradually evaporimeter 6 (indoor heat converter); Indoor fan 7; Room air guiding 8 (8a, 8b, 8c); Fan electromotor 14; Dividing plate 8a (double action); The outside of dividing plate is provided with compressor 16; Outdoor fan 11; Outdoor air guiding 10; Condenser 12 (outdoor heat converter) constitutes.
Referring to Fig. 2, with the window air conditioner cooling operation is that example illustrates that the operation principle of existing window air conditioner is as follows: when powering up to window air conditioner, its compressor 16, fan electromotor 14 and indoor centrifugal fan 7, outdoor aerofoil fan 11 runnings, room air is sucked by air entry 4a under the effect of centrifugal fan 7, when evaporimeter 6 and the refrigerant fluid heat exchange that circulates in its refrigerant pipe, after being cooled, air enters in the centrifugal fan 7, air in centrifugal fan 7 through the fan centrifugal action along 8a, 8b, air guiding 8 and upside exhaust outlet 4b that 8c forms flow back to indoor again, reach the purpose of indoor refrigeration, this moment is the cold media gas after the heat absorption evaporation in evaporimeter, sucked back by compressor, compressed machine compression back row is to condenser 12, condenser 12 is loaded on the outdoor section of window air conditioner, outdoor air is under the effect of aerofoil fan herein, pore 1 on cabinet 2 enters cabinet 2 after-blow to condenser 12, make the heat that is compressed refrigerant in the condenser and air heat exchange and be discharged in the outdoor environment by air, make refrigerant be condensed into liquid, the evaporation absorption refrigeration that expands behind expansion valve again forms the refrigerant circulation successively.
Evaporimeter and condenser in the air-conditioner are referred to as heat exchanger, general air-conditioning has water-cooled and air-cooled type heat exchanger, among air-cooled type heat exchanger such as Fig. 1-4 6, shown in 12, with the air is the heat exchange cooling medium, the refrigerant fluid circulates in the shape refrigerant pipe that turns back of heat exchanger more, air skims over outside the refrigerant pipe, in order to improve refrigerant and the heat exchange efficiency of managing outer air in the pipe, refrigerant pipe outer wall vertical direction at heat exchanger is installed fin 19, heat exchanger by heat conduction good cover copper-aluminum wrapped calandria and aluminum alloy fin is dressed up with expand tube method or welding, as shown in Figure 3, the heat exchanger tube group is by covering copper-aluminum wrapped calandria and U-shaped copper pipe elbow welds with gas, couple together with brazing or silver soldering.
Now, generally with liquefied petroleum gas oxygen or other gas welding method with nozzle 18 with U-shaped copper pipe elbow with cover the copper-aluminum wrapped calandria welding, still, this welding method is owing to existing reasons such as the irregular and aluminum ratio copper fusing point of heating is low often aluminum pipe to be burnt and bad reparation.
