Problems solved by technology

[0002] The condensing heat exchanger of the existing gas water heater adopts a spiral corrugated pipe, which is fixed on the lower end cover through threads at the water inlet and outlet joints. If the corrugated pipe is not fixed, it will vibrate during transportation and normal operation, causing abnormal noise and hidden dangers of resonance; Meet the national standard for condenser efficiency requirements, the bellows are longer

Abstract

The invention discloses a parallel type gas water heater condensation heat exchanger. The parallel type gas water heater condensation heat exchanger comprises a cavity and multiple corrugated pipes arranged in the cavity in parallel. The parallel type gas water heater condensation heat exchanger is characterized in that corrugated pipe fixing discs are arranged at the two ends of the corrugated pipes; end covers are arranged on the upper portion and the lower portion of the cavity; two small chambers used for water catchment and water diversion are formed by the end covers and the corrugated pipe fixing discs; the cavity is provided with a flue gas guide-in / guide-out inlet and outlet; and a condensation water collection device and flue gas guide pieces are further arranged in the cavity. The condensation heat exchanger with the above structure has the beneficial effects of being capable of eliminating vibration hidden danger, reducing material application and reducing cost.

Description

technical field [0001] The invention relates to the technical field of gas instant water heaters, in particular to a condensing heat exchanger of a gas instant water heater. Background technique [0002] The condensing heat exchanger of the existing gas water heater adopts a spiral corrugated pipe, which is fixed on the lower end cover through threads at the water inlet and outlet joints. If the corrugated pipe is not fixed, it will vibrate during transportation and normal operation, causing abnormal noise and hidden dangers of resonance; It meets the national standard for condenser efficiency requirements, and the bellows are longer. For example, the patent name is a high-efficiency condensing heat exchanger, the application publication number is CN104296383A, the application publication date is 015.01.21, the application number is 2014105325777, and the application date: an invention of 2014.10.10 discloses a high-efficiency condensing heat exchanger. It includes a shell,...
