Problems solved by technology

[0002] In the prior art, most of the heat exchangers used in the general gas water heater industry are made of oxygen-free copper. The surface of the combustion chamber is covered with coils. The length of the water pipe is long, the heating is slow, and the water resistance in the pipe is large. The flow rate is small, which affects the user's comfortable bathing style, and a large amount of copper is used, resulting in high overall cost of the heat exchanger; and the current stainless steel heat exchanger, due to problems such as heat exchange tube shape and heat exchange fin design, causes heat exchangers The heat transfer effect is not ideal, and the heat transfer efficiency is not high

Abstract

The invention discloses a heat exchanger. The heat exchanger comprises a fin assembly and a plurality of heat exchange tubes, wherein the fin assembly comprises a plurality of heat exchange pieces which are stacked at intervals, and a heat exchange channel for flue gas circulation is defined between every two adjacent heat exchange pieces; the heat exchange tubes are arranged in the fin assembly in an inserted manner through the heat exchange pieces, and the heat exchange tubes sequentially communicate with one another to form a water flow channel; and each heat exchange tube is a waist-shapedflat tube, and the length direction of the cross section of each heat exchange tube is parallel to the inflow direction of flue gas. The heat exchange tube has the beneficial effects that the heat exchange tubes are arranged to be the flat tubes, the length direction of the cross section of each heat exchange tube is parallel to the inflow direction of the flue gas, and therefore the effective heat exchange area can be increased; and the heat efficiency is guaranteed, the water path system can be properly shortened and simplified, and the cost of the heat exchanger is reduced.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a heat exchanger for a gas water heater. Background technique [0002] In the prior art, most of the heat exchangers used in the general gas water heater industry are made of oxygen-free copper. The surface of the combustion chamber is covered with coiled pipes. The length of the water pipe is long, the heating is slow, and the water resistance in the pipe is large. The flow rate is small, which affects the user's comfortable bathing style, and a large amount of copper is used, resulting in high overall cost of the heat exchanger; and the current stainless steel heat exchanger, due to problems such as heat exchange tube shape and heat exchange fin design, causes heat exchangers The heat exchange effect is not ideal, and the heat exchange efficiency is not high. Contents of the invention [0003] The purpose of the present invention is to overcome the deficienci...
