A high-performance all-iron condenser and its manufacturing method

Abstract

The invention discloses a high-temperature total-iron condenser and a manufacturing method thereof. The condenser comprises a shell; tube plates are arranged inside the shell; the two tube plates aresymmetrically and aslant arranged; a fixing plate is arranged between the two tube plates; first copper tubes are arranged between the two tube plates; the lengths of the first copper tubes are gradually decreased from top to bottom; and a second copper tube is connected between every two adjacent first copper tubes. The manufacturing method comprises the steps of a, tapping treatment of the tubeplates; b, corrosion resistance treatment of the tube plates; c, splicing of the tube plates; d, penetration of the first copper tubes into holes of the tube plates; e, bending operation of the secondcopper tubes; and h, pressure test. The high-temperature total-iron condenser and the manufacturing method thereof can adapt to the state that the size of the shell is gradually reduced, so that thearea of the condenser is effectively used, the structure is compact, and the heat exchange efficiency is improved; and in the manufacturing method, bending operation can be conducted on the multiple second copper tubes at the same time, the radian uniformity of the second copper tubes is improved, the first copper tubes and the second copper tubes are connected conveniently, connection tightness of the first copper tubes and the second copper tubes is improved, and the manufacturing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of condenser equipment, and in particular relates to a high-performance all-iron condenser and a manufacturing method thereof. Background technique [0002] The condenser is a component of the refrigeration system, which is a kind of heat exchanger, which can convert gas or vapor into liquid, and transfer the heat in the tube to the air near the tube in a very fast way. The working process of the condenser is an exothermic process, so the temperature of the condenser is relatively high. [0003] In the air conditioning system, the all-iron condenser has the most potential. The all-iron condenser is a new structural form developed after the tube-belt type. It is a refrigerant channel composed of two aluminum plates punched into complex shapes. The all-iron condenser also requires double-sided composite aluminum, and the welding requirements are higher. As long as there is a small unwelded gap between the tw...
