Description
Technical Field
The utility model relates to a domestic gas heater heat exchanger for collect heat energy, heat cold water into hot water and flow out.
Background
The existing gas water heaters all adopt heat exchangers, cold water enters a heat exchange pipe in the heat exchanger through a water inlet pipe and a coil pipe outside the heat exchanger for heat exchange, and the heated water is discharged to a water outlet pipe through the heat exchange pipe; the heat exchange tubes in the existing heat exchanger are arranged in a mode, the arrangement quantity directly influences the heat efficiency and the product cost of a water heater, and in order to improve the market competitiveness, the requirement of low cost is required to be met while the requirement of the heat efficiency is met, so that the product structure has a great room for improvement.
Disclosure of Invention
The invention provides an optimized structural design of a heat exchanger of a household gas water heater, aiming at further reducing the cost while meeting the requirement of thermal efficiency.
The invention adopts the following technical scheme:
the utility model provides a domestic gas heater heat exchanger, adopts a plurality of heat exchanger fin to fold and forms heat exchanger fin group, set up 8 heat exchange tubes that lead to water in the heat exchanger fin group, the heat exchange tube divides the three-layer to arrange, and 3 heat exchange tubes are distributed to the upper strata, and 2 heat exchange tubes are distributed to the middle level, and 3 heat exchange tubes are distributed to the lower floor.
The heat exchange tube is in a circular tube shape, an elliptical tube shape or a square tube shape.
And a plurality of flue gas channels are arranged around the heat exchange tube.
The smoke channel is round or oval.
The utility model has the advantages that:
because 8 heat exchange tubes are adopted and arranged in three layers, the requirement on heat efficiency is met, and meanwhile, the production cost is greatly reduced.

Detailed Description
Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These exemplary embodiments are provided so that those skilled in the art can clearly understand the present invention and can implement the present invention according to the description herein. The drawings and detailed description are not intended to limit the invention, which is defined by the appended claims.
Referring to fig. 1, a heat exchanger of a household gas water heater adopts a plurality of heat exchange sheets to form a heat exchange sheet set.
As shown in fig. 2, 8 water-through heat exchange tubes are arranged in the heat exchange tube group, the heat exchange tubes are arranged in a heat exchange tube channel (2), the heat exchange tubes are arranged in three layers, 3 heat exchange tubes are distributed on the upper layer, 2 heat exchange tubes are distributed on the middle layer, and 3 heat exchange tubes are distributed on the lower layer;
the heat exchange pipes are connected end to form an S-shaped water channel, so that cold water can be heated in the heat exchanger for a long time.
The heat exchange tube, the shape is for pipe or oval tube or square tube all can, preferredly adopts the pipe, because the pipe processing is convenient, the cost is lower.
Referring to fig. 2, a plurality of flue gas channels are arranged around the heat exchange tube, and the flue gas channels can be designed into a circular shape or an oval shape, and are flexibly designed according to the size and the shape of a product, so that the requirements of stable structure and reduction of materials and weight are met.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention.
