Description

Technical Field

[0001] The utility model relates to the technical field of water heater heat exchangers, in particular to a high-efficiency household water heater heat exchanger. Background Art

[0002] Household water heaters are an indispensable part of modern family life. They heat cold water in various ways to provide hot water for the family.

[0003] There are many types of household water heaters, among which gas water heaters are the most commonly used. The specific working principle of gas water heaters is to heat hot water by burning natural gas or liquefied petroleum gas. Among them, the heat exchanger is the core component of the gas water heater. Its function is to transfer the heat generated by combustion to the water to heat the water.

[0004] At present, the existing heat exchangers for gas water heaters mostly use a very thin red copper material for the heat exchanger shell. Since the red copper material is relatively soft, after long-term use, the red copper heat exchanger shell is prone to shell deformation, which in turn affects the normal heat exchange effect.

[0005] In addition, its water inlet and outlet pipes are prone to shaking and have weak supporting strength, which results in poor stability of hot water circulation inside the water inlet and outlet pipes. Moreover, the heat of hot water in the water inlet, outlet and circulation pipes is easily dissipated into the air, which overall reduces the stability, anti-shaking and heat preservation efficiency of the water inlet, outlet and circulation pipes on the heat exchanger for the gas water heater during hot water transportation.

[0006] The above problems are widespread and urgently need to be improved. Utility Model Content

[0007] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose a high-efficiency heat exchanger for domestic water heaters.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A high-efficiency household water heater heat exchanger is designed, comprising a heat exchanger body, a heat exchanger shell is arranged on the heat exchanger body, a water inlet pipe and a water outlet pipe are arranged on the heat exchanger shell, a circulation pipe is arranged around the outer wall surface of the heat exchanger shell, the circulation pipe is respectively connected to the water inlet pipe and the water outlet pipe, and a mounting plate is arranged on the heat exchanger shell;

[0010] The mounting plate is provided with an external reinforcement rib, the heat exchanger shell is provided with an internal reinforcement rib, the internal reinforcement rib is provided with a vertical stabilizing column, and the vertical stabilizing column is provided with a first reinforcement rod and a second reinforcement rod;

[0011] The water inlet pipe and the water outlet pipe are both provided with supporting connecting rods, the supporting connecting rods are provided with auxiliary top plates, the auxiliary top plates are provided with weight reduction ports, and the outer walls of the water inlet pipe, the water outlet pipe and the circulation pipe are all provided with thermal insulation and protective layers.

[0012] Furthermore, the outer reinforcement ribs are in the form of triangular strips as a whole, and there are four outer reinforcement ribs symmetrically arranged and respectively fixed to the outer wall surface of the heat exchanger shell and the mounting plate.

[0013] Furthermore, the internal reinforcement ribs are a triangular plate structure as a whole, and the internal reinforcement ribs are symmetrically arranged in four groups and seven in number arranged vertically.

[0014] Furthermore, the vertical stabilizing columns are symmetrically arranged in four groups, with two columns in each group, and the vertical stabilizing columns vertically penetrate the inner reinforcement ribs.

[0015] Furthermore, the first reinforcing rod and the second reinforcing rod are both symmetrically arranged, and both ends of the first reinforcing rod and the second reinforcing rod are respectively fixed to the vertical stabilizing column.

[0016] Furthermore, the supporting connecting rod is an inclined structure as a whole and has an angle of twenty-eight degrees with the horizontal plane, the auxiliary top plate is an overall triangular plate structure, the auxiliary top plate is an inclined structure and has an angle of sixty-eight degrees with the horizontal plane, and the weight-reducing opening passes through the auxiliary top plate.

[0017] Furthermore, the thermal insulation and protective layer is a slag wool pad structure.

[0018] The utility model proposes a high-efficiency household water heater heat exchanger, which has the following beneficial effects:

[0019] 1. The utility model arranges external reinforcement ribs between the heat exchanger shell and the mounting plate, arranges internal reinforcement ribs with vertical stabilizing columns inside the heat exchanger shell, and then arranges a first reinforcement rod and a second reinforcement rod structure between the vertical stabilizing columns, thereby improving the structural stability of the heat exchanger shell as a whole, effectively avoiding deformation of the heat exchanger shell which is mostly made of very thin and soft red copper material, thereby ensuring the normal heat exchange working effect of the heat exchanger body for the gas water heater.

[0020] 2. The utility model arranges supporting connecting rods on the water inlet pipe and the water outlet pipe, and arranges a sub-top plate structure on the supporting connecting rods, and at the same time arranges a thermal insulation protective layer structure on the outer wall surfaces of the water inlet pipe, the water outlet pipe and the circulation pipe. This not only improves the supporting strength and anti-sway performance of the water inlet pipe and the water outlet pipe, and ensures the hot water circulation stability inside the water inlet pipe and the water outlet pipe, but also effectively prevents the heat of the hot water in the water inlet pipe, the water outlet pipe and the circulation pipe from being dissipated into the air, thereby overall improving the stability, anti-sway and thermal insulation efficiency of the water inlet pipe, the water outlet pipe and the circulation pipe on the heat exchanger body for the gas water heater during hot water transportation.

[0031] The outer reinforcement ribs 22 are triangular strip structures as a whole. There are four symmetrically arranged outer reinforcement ribs 22 and they are fixed to the outer wall surface of the heat exchanger shell 2 and the mounting plate 21 respectively. The heat exchanger body 1 is a heat exchanger for a gas water heater, which is the prior art.

Some existing structures are not drawn and marked, so there is no need to repeat them.

[0032] The inner reinforcing ribs 3 are of a triangular plate structure as a whole. The inner reinforcing ribs 3 are symmetrically arranged in four groups and are seven in a vertical arrangement. The inner reinforcing ribs 3 of the triangular plate structure improve the strength of the inner ninety-degree corner of the heat exchanger shell 2 and prevent deformation.

[0033] The vertical stabilizing columns 31 are symmetrically arranged in four groups, with two columns in each group. The vertical stabilizing columns 31 vertically penetrate the inner reinforcement ribs 3 . The vertical stabilizing columns 31 further improve the structural stability between each inner reinforcement rib 3 , thereby ensuring the stability and anti-deformation effect of the heat exchanger shell 2 .
