Problems solved by technology

However, the flow path is too long, the flow resistance is large, and the performance is low
[0010] On the heat exchanger of the automobile air conditioner, a laminated heat exchanger is also used, which is formed by stamping 0.50-0.40mm aluminum foil and stamped by the heat dissipation plate, forming a refrigerant channel after the two heat dissipation plates are superimposed (see Figure 6 and Figure 6a), but its lamination width is limited, there are defects such as excessive product thickness, too many welding points, and pressure difference
[0011] Although in recent years, some flat tubes formed by extrusion technology have appeared, but the wall thickness of these flat tubes can only be 0.45mm.

Abstract

A heat exchanger has No.1 and No.2 manifolds with joint holes, many parallel flat tubes connecting inserting into joint holes of No.1 and No.2 manifolds, outer fins between adjacent flat tubes, with each flat tube unit composed of at least one flat through channels. There is a parallel section between the flat tubes through channels. The said flat tube channel is made of aluminum extrusion of thin wall section bars, with over one coolant and heating flow channels. It applies to horizontal flow cooler of vehicle transmission and horizontal flow water tank of automobile engine coolant, and horizontal warm air core for warm air for auto air conditioner.

Description

technical field [0001] The invention relates to cold and heat exchanging products, in particular to a product made of flat tubes, which improves the cross-sectional shape and structure of the flat tubes and improves the thermal efficiency of the cold and heat exchangers. The cold and heat heat exchanger is especially suitable for automotive oil coolers, automotive water tanks, heater cores for automotive air conditioners, and evaporator cores for automotive air conditioners. Background technique [0002] The conventional heat exchanger is shown in Figure 1-Figure 4, the inlet 1 for the cooling medium and the outlet 2 for discharging the condensed water are arranged on the first header 4 with a partition, and many flat tubes passing through the cooling medium 5. Connect the above-mentioned first header 4 and second header 6 in parallel at a certain interval. Furthermore, corrugated plates 7 for heat exchange are arranged between the flat tubes. The heat exchange process of ...
