Connecting board assembly, water heater water tank and assembling method of water heater water tank

Abstract

The invention discloses a connecting board assembly. The connecting board assembly comprises a positioning support, a connecting board and two connecting supports, wherein the positioning support is provided with a screw hole; the connecting supports are provided with through holes, screw holes are arranged adjacent to the through holes and used for matching with the thread holes in the positioning support; both ends of the connecting board is respectively provided with an inwards-bended hook; the positioning supports is used for being connected with one of the two connecting supports; the hooks at both ends of the connecting board are matched with the through holes in the connecting supports, and both ends of the connecting board are respectively connected with a corresponding connecting support. The invention also relates to a water heater water tank with the connecting board assembly and an assembling method of the water heater water tank. The connecting board assembly is used for fixing metal heat exchange tubes, is simple in structure and easy to operate, facilitates flow process and improves the production efficiency; the fixed metal heat exchange tubes are in close contact with the liner of the water tank, thereby improving the heat exchange efficiency.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a connecting plate assembly, a water tank of a water heater and an assembly method thereof. Background technique [0002] Heat pump water heaters will become the development direction of household water heaters in the future because of their advantages of mainly using heat energy in the air as energy and safety and environmental protection. Heat pump water heaters use the reverse Carnot principle to transfer heat from low-temperature objects to high-temperature water through media. device of. The heat pump device can change the phase of the medium (refrigerant) to become lower than the low-temperature heat source, thereby spontaneously absorbing the heat of the low-temperature heat source, returning to the medium after the compressor, and being compressed into a high-temperature (higher than high-temperature water) high-pressure gas , so as to spontaneously emit heat to a ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the water tanks of heat pump water heaters on the market use heat-exchange metal tubes to be wound on the outer surface of the water tank liner to form a condenser, and screws are used to fix the heat-exchange metal tubes on the water tank liner; there are also two collector tubes, namely One end of multiple heat-exchange metal tubes is connected to one of the headers, and the other end is connected to the other header. The multiple heat-exchange metal tubes are respectively used as branch pipes of the two headers, and are screwed together. The two collecting pipes are fixed on the inner tank of the water tank; the above two installation methods have high technical requirements and are troublesome to install
