Abstract
A heat exchanger of a gas water heater comprises a water inlet pipe, a water outlet pipe, a heat exchange pipe, a heat exchanger casing and heat exchange fins, wherein the water inlet pipe, the water outlet pipe and the heat exchange pipe are communicated to form a complete heat exchange pipeline. The heat exchanger is characterized in that the water inlet pipe, the water outlet pipe and the heat exchange pipe are formed by bending one pipe, kidney-shaped holes are formed in the heat exchange fins, and the heat exchange pipe is inserted into the kidney-shaped holes so as to fix the heat exchange fins on the heat exchange pipe. The heat exchanger of the gas water heater has the advantages that the water leakage failure can be effectively prevented, and the performance is reliable.
Description
Technical field
The utility model relates to a kind of heat exchanger of gas heater.
Background technology
In the prior art, usually use U-shaped pipe to connect in the heat exchanger of gas heater between the heat exchange straight tube, the interface of its connection easily is stained with scaling powder in process, scaling powder produces corrosion when the heat exchanger operate as normal, make heat exchanger that water leakage fault easily take place, and then influence service life of heat exchanger, cause to exist heat exchanger easily to produce water leakage fault defective such as reliability is bad.For overcoming these defectives, the heat exchanger of gas heater is improved.
Summary of the invention
Technical problem to be solved in the utility model is the heat exchanger that a kind of gas heater will be provided, and it can make the heat exchanger of gas heater be difficult for producing water leakage fault effectively, and then performance is more reliable.
The technical scheme that its technical problem that solves the utility model adopts is:
It comprises water inlet pipe, outlet pipe, heat exchanger tube, outer cover of heat exchanger, heat exchanger fin, water inlet pipe, outlet pipe and heat exchanger tube are communicated with into complete heat exchanging pipe, described water inlet pipe, outlet pipe, heat exchanger tube are formed by the bending of a pipe, heat exchanger fin is provided with mounting hole, thereby heat exchanger tube inserts mounting hole heat exchanger fin is fixed on the heat exchanger tube.
Described heat exchanger fin is provided with spoiler.
It also comprises auxiliary heat exchanger fin, and auxiliary heat exchanger fin is fixed in the mounting hole of heat exchanger fin.
Described water inlet pipe, outlet pipe, heat exchanger tube, outer cover of heat exchanger and heat exchanger fin are that aluminium alloy, copper or stainless steel material are made.
Water inlet pipe is coiled on the outer cover of heat exchanger.
Outlet pipe is coiled on the outer cover of heat exchanger.
The utility model is compared the beneficial effect that produces with background technology:
1, because the utility model adopts water inlet pipe, outlet pipe and heat exchanger tube are formed by the bending of a pipe, heat exchanger fin is provided with mounting hole, thereby heat exchanger tube inserts mounting hole heat exchanger fin is fixed on structure on the heat exchanger tube, do not need heat exchange straight tube of the prior art, U-shaped pipe, being welded to connect between the coil pipe, water inlet pipe and outlet pipe do not use welding procedure with being communicated with of heat exchanger tube respectively, whole pipeline does not use scaling powder, the problem that does not have scaling powder corrosion heat exchanger, so it can make the heat exchanger of gas heater be difficult for producing water leakage fault effectively, and then performance is more reliable.
Description of drawings: Fig. 1 is structural representation of the present utility model.
