The invention discloses a double plate integrated parallel flow heat exchanger for a bus air conditioner. The double plate integrated parallel flow heat exchanger for the bus air conditioner is in a double-layer heat transmission structure and is composed of a heat transmission core unit and side plates above and under the heat transmission core unit, wherein the heat transmission unit is composed of collecting manifolds at the left end and the right end, between which flat tubes are inserted, and fins are arranged among the flat tubes; each collecting manifold of the heat transmission core unit is welded with an L-shaped support, an inlet connector and an outlet connector, and the heat transmission core unit is welded with a strengthening seat; the fins, the side plates, the flat tubes and the collecting manifolds are assembled in an integrated mode. The double plate integrated parallel flow heat exchanger for the bus air conditioner is in the double-layer integrated structure, and the internal core unit can achieve integrated assembly, so that, compared with the prior art, materials and machining costs can be saved, the production efficiency and yield rate of core unit assembly and heat exchanger overall welding can be improved, and consistency and reliability of machined products can be enhanced. The double plate integrated parallel flow heat exchanger for the bus air conditioner has the advantages of being high in integral strength, stable in structure, high in reliability, easy to machine, low in production cost, high in yield rate and the like.
Description
technical field [0001] The invention relates to the technical field of heat exchange for bus air conditioners, in particular to a double-plate integrated parallel flow heat exchanger for bus air conditioners. Background technique [0002] Parallel flow heat exchangers are key accessories commonly used in bus air conditioners. At present, there is a double-layer parallel flow heat exchanger for bus air conditioners. This heat exchanger is two separate parallel flow heat exchangers after processing. , and then superimpose the two together for argon arc welding connection or direct argon arc welding to connect the two and then perform overall brazing. The heat exchanger in this state has complex processing process, high production cost, low yield, and overall Unstable structure, insufficient core strength, poor installation consistency and other disadvantages. As the heat exchangers of bus air conditioners began to slowly switch to the parallel flow structure, with the continu...
