Finned tubular heat exchanger

Abstract

The invention discloses a finned tubular heat exchanger. The finned tubular heat exchanger comprises a heat exchange component, a first end cover and a second end cover, wherein the first end cover and the second end cover are correspondingly used for covering the two end parts of the heat exchange component; the heat exchange component comprises a heat exchange tube and a plurality of heat exchange plates; the heat exchange tube adopts a water path system which forms a cylindrical shape by integrated molding and bending; all heat exchange plates are arranged on the water path system in a spaced and sleeving manner along a center shaft of the water path system; the water path system comprises a plurality of tube units which are connected in sequence; each tube unit comprises a first straight tube section, a first bent tube section, a second straight tube section and a second bent tube section which are connected in sequence; each first straight tube section is connected to the second bent tube section of the adjacent tube unit; all first straight tube sections form an outer layer heat exchange structure of the water path system; and all second straight tube sections form an inner layer heat exchange structure of the water path system. The finned tubular heat exchanger disclosed by the invention has the beneficial effects of preventing water leakage of the heat exchange tube andalso realizing uniform heating and high thermal efficiency.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a finned tube heat exchanger. Background technique [0002] Heat exchanger is one of the core components of gas heating water heater and gas water heater, which is related to the service life and safety of the product. In traditional heat exchangers, most of them adopt finned tube structure or plate structure, while the water system in finned tube heat exchangers is generally welded by several straight tubes and U tubes. Water leakage; the water system in the plate heat exchanger is all welded. The welding effect directly affects the sealing of the heat exchanger, and the pressure bearing capacity is also lower than that of the finned tube heat exchanger, which is prone to leakage . Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a finned tube heat exchanger with good sealing...
