Problems solved by technology

[0002] The heat (cold) exchange tubes of the existing air conditioner heat exchangers (cold) are processed by expanding and tightening after the tubes are covered with fins. After thermal expansion and contraction, the contact thermal resistance between the tube and the fins continues to increase, resulting in a rapid decrease in heat transfer performance and shortened service life

Embodiment Construction

[0018] Such as Figures 1 to 3 As shown, the air conditioner uses a three-dimensional finned tube cooling and heat exchanger, including an inlet 1, an outlet 2, and a flow line between the two. The flow line includes a three-dimensional finned tube 5 as a heat transfer element, The three-dimensional ribbed tube refers to a metal tube with ribs cut on the tube wall. The ribs are carved and cut on the surface wall of the metal tube (along the direction of the central axis of the metal tube) by several circularly arranged blades, and each blade is precisely controlled by a CNC machine tool.

[0019] The three-dimensional rib tube cooling and heat exchanger for the air conditioner comprises a left orifice plate 3, a right orifice plate 4, and a three-dimensional rib tube 5. There are several mounting holes on the orifice plate, and the three-dimensional rib tube 5 passes through the left orifice plate 3 and the right orifice plate 4. Fixed, the pipes of the three-dimensional ribb...

Abstract

The invention discloses a three-dimensional inner and outer finned tube cold and heat exchanger for an air conditioner. The three-dimensional inner and outer finned tube cold and heat exchanger comprises a flow inlet, a flow outlet and a flow pipeline between the flow inlet and the flow outlet, wherein the flow pipeline comprises a three-dimensional finned tube which is fixedly arranged on left and right perforated plates as a heat transfer element; and the three-dimensional finned tube indicates a metal tube with fins cut on the tube wall. According to the three-dimensional inner and outer finned tube cold and heat exchanger, the technical defects of low heat exchange performance between the tube and fins of the heat (cold) exchange tube for an air conditioner and short service life in the prior art are overcome; and the three-dimensional inner and outer finned tube cold and heat exchanger for the air conditioner with high heat exchange performance and long service life is provided.

Description

technical field [0001] The invention relates to a heat exchanger (cooler) for an air conditioner, namely an air conditioner evaporator and a condenser, which is a tubular heat exchanger with a three-dimensional inner and outer finned tube as its heat transfer element. Background technique [0002] The heat (cold) exchange tubes of the existing air conditioner heat exchangers (cold) are processed by expanding and tightening after the tubes are covered with fins. The heat exchange effect of the new products is still good, but with the increase in the number of starts and stops, After thermal expansion and contraction, the contact thermal resistance between the tube and the fins continues to increase, resulting in a rapid decrease in heat transfer performance and shortened service life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-efficiency heat exchanger (cooler) for an air conditioner with completely el...
