Heat exchanger structure and assembly method thereof

Abstract

The invention discloses a heat exchanger structure, which comprises an inlet collecting pipe, an outlet collecting pipe, fins, a flat pipe and gaskets, wherein the fins are provided with pipeline grooves, and the inside diameter of the gaskets is smaller than the thickness of the flat pipe. The invention also discloses an assembly method for the heat exchanger structure, which comprises the following steps of: (1) heating the gasket; (2) correspondingly arranging the fins and the gaskets on a bearing table layer by layer; (3) sequentially inserting the flat pipe into the fins and the gaskets so that the flat pipe can pass through the radiating gaskets to form clearance fit; (4) pushing a pressing table by using pressing equipment to press the fins and the gaskets so that the fins and the gaskets are tightly jointed; and (5) keeping constant pressure, blowing cool air to the gaskets, and cooling the gaskets to normal temperature so that the gaskets and the flat pipe form clearance fit and fixed connection of the fins and the flat pipe is completed. The structure is easy to assemble; the contact area of the fins and the radiating gaskets is original four times, so the radiating efficiency of a radiator is promoted; and due to a fixed mode, soldering is avoided, a solder is saved, and the cost is reduced.

Description

technical field [0001] The invention relates to a condenser, in particular to a heat exchanger structure and an assembly method thereof. Background technique [0002] When the room air conditioner is running in cooling mode, the indoor air flows through the evaporator to reduce the temperature. At the same time, because the temperature of the surface of the evaporator is generally significantly lower than the dew point temperature of the air, when the air flows through the surface of the evaporator, part of the moisture in the air will be precipitated, thereby forming condensed water on the surface of the evaporator. Condensed water on the surface of the evaporator should be drained in time. If the condensed water accumulates on the surface of the evaporator, it will block the air passage, increase the flow resistance of the air, and reduce the efficiency of the evaporator: water droplets may also be blown into the room, resulting in unqualified quality of the air condition...
