Problems solved by technology

Since the micro-channel is fixedly connected to the water tank liner through the connecting plate and bolts, it is necessary to manually align the screw holes with a pneumatic screwdriver, which cannot realize automatic assembly, and the efficiency is low; and because the micro-channel is connected by bolts, it can withstand tensile force and shear for a long time There is a risk of bolt thread failure, which will lose the tension on the microchannel and reduce the heat transfer efficiency

Abstract

The invention relates to a hitching structure, a water tank assembly and a heat-pump water heater. The hitching structure comprises a first component, a second component and an elastic third component, wherein one end of the third component is separably connected with a first hitching part of the first component, the other end of the third component is separably connected with a second hitching part of the second component, and the third component is used for tensioning the first component and the second component together; further, the distance between the first hitching part and the second hitching part is changeable, and accordingly, tensioning force of the third component between the first component and the second component is adjustable. The structure is simple, the operation is convenient, and the assembly efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a hook structure, a water tank assembly and a heat pump water heater. Background technique [0002] At present, most of the water tank components of heat pump water heaters include a water tank liner and micro-channels wrapped on the outer surface of the water tank liner. The micro-channels generally include several heat exchange pipes arranged in parallel. The other ends of the heat exchange pipes are connected to another collecting pipe, and connecting plates are arranged on the two collecting pipes, and the micro-channel is fastened to the inner tank of the water tank through the connecting plate and bolts. Since the micro-channel is fixedly connected to the water tank liner through the connecting plate and bolts, it is necessary to manually align the screw holes with a pneumatic screwdriver, which cannot realize automatic assembly, and the efficiency is low; and because...
