Description
Technical Field
The utility model relates to a heat exchanger technical field specifically is a closed forced air cooling heat exchanger.
Background
The existing air-conditioning heat exchanger can be divided into several forms such as 'tube sheet type', 'tube belt type', 'stacked' and 'parallel flow' according to the structure.
The parallel flow type heat exchanger has the highest heat transfer efficiency and is a more advanced heat exchanger developed in recent decades, but the heat exchanger needs to be integrally welded and manufactured in a brazing furnace, so the heat exchanger cannot be too large in size due to the limitation of equipment, and the parallel flow type heat exchanger is only suitable for being used as a trolley air conditioner condenser at present.
The 'tube sheet type' heat transfer performance is poor, but the volume can be larger because only local flame welding is needed, so that the 'tube sheet type' heat transfer performance is widely used on large-scale air conditioners and household air conditioners at present. However, because the heat transfer effect is poor, the volume of the tube sheet type air conditioner and the volume of the parallel flow type air conditioner are 2-3 times that of the tube sheet type air conditioner under the condition of the same power, the tube sheet type air conditioner and the parallel flow type air conditioner rarely adopt a tube sheet type structure.
The 'tube-strip-type' structure also needs to be integrally welded and manufactured in a brazing furnace, and the performance is about half lower than that of the 'parallel flow-type', so that the 'tube-strip-type' structure is basically eliminated at present and exits the mainstream market.
The laminated structure is manufactured by processing a die into sheet metal parts, then stacking the sheet metal parts one by one in a brazing furnace and integrally welding the sheet metal parts in the brazing furnace, and the laminated structure is limited by a processing process and cannot be used for manufacturing a large-size product, so that the laminated structure can only be used as an evaporator of a trolley air conditioner basically.
