Water heater and heat exchanger assembly

Abstract

The invention discloses a heat exchanger assembly, which includes a water tank, a collecting pipe and a flat tube are arranged on the outer wall of the water tank, the flat tube is inserted into the collecting pipe, and the collecting pipe The bottom has a boss that fits snugly with the outer wall of the water tank. During assembly and use, the contact area between the collecting pipe and the water tank is effectively increased through the fitting structure between the boss and the outer wall of the water tank, and the heat exchange between the collecting pipe and the water tank is improved, so that the The overall heat exchange efficiency of the heat exchanger assembly is correspondingly improved, and at the same time, the boss structure can provide additional structural support for the header to ensure a more stable and reliable matching structure between the header and the water tank. The invention also discloses a water heater using the heat exchanger assembly.

Description

technical field [0001] The invention relates to the technical field of water heater matching components, in particular to a heat exchanger assembly. The invention also relates to a water heater using the heat exchanger assembly. Background technique [0002] In daily production and life, water heaters are widely used in all aspects of different fields, and the performance of water heaters is also increasingly concerned by people. [0003] In the heat exchanger assembly structure of the existing traditional water heater, it is generally connected by a plurality of flat tubes in the middle of two collecting pipes, and the collecting pipes are usually round pipes, which makes the space between the collecting pipes and the side wall of the water tank Line contact, the other walls of the collector and the connection between the collector and the flat tube cannot be in contact with the inner tank of the water tank, so that the heat cannot be transferred to the inner tank of the w...
