Problems solved by technology

[0004] There is a fixed rod on the front and rear sides of the top of the combustion chamber. The existing fixed rods usually adopt an L-shaped structure. During the process of pressurizing and decompressing the heat exchanger, some vibrations will occur. The L-shaped fixed rod supports the strength Not enough, the heat exchanger is prone to metal fatigue during repeated vibrations, which affects the product life
[0005] The supporting feet on the same edge of the left end plate and the right end plate are not on the same plane, which is not only difficult to process, but also requires more materials and is more difficult to install

Embodiment Construction

[0029] Such as Figure 1 to Figure 4 As shown, a heat exchanger is mainly composed of a combustion chamber and a gas mixing chamber on the top of the combustion chamber. There are multiple fins 1 in the combustion chamber, a left end plate 2 is provided on the left side of the combustion chamber, and a Right end plate 3. A fixing rod 4 is respectively arranged on the front and rear sides of the top of the combustion chamber, and is used to fix the combustion chamber and the gas mixing chamber together.

[0030] Such as Figure 5 and Figure 6 As shown, each fin is provided with a plurality of protrusions, and the protrusions shrink from the inlet end of the combustion chamber to the smoke outlet, so that the cross-sectional area of ​​the entrance end of the protrusions is larger than that of the outlet end. From the inlet end of the combustion chamber to the direction of the smoke outlet, the protruding inner wall forms a section, and part of the hot air flow entering the p...

Abstract

A heat exchanger is mainly composed of a combustion chamber and a fuel gas mixing chamber arranged on the top of the combustion chamber. A plurality of fins are arranged inside the combustion chamber. A left end plate is arranged on the left side of the combustion chamber. A right end plate is arranged on the right side of the combustion chamber. A plurality of protrusions are arranged on the fins. The contact area between the fins and hot air flow is increased, and heat among the fins can also be balanced. A fixing rod is in a triangular prism shape. The supporting capacity is enhanced, the oscillation resistance is higher, and deformation of the fixing rod is smaller than that of an L-shaped fixing rod, so that the service life of the heat exchanger is prolonged.

Description

technical field [0001] The invention relates to a heat exchanger of a gas wall-mounted heater, which belongs to the optimization technology of the heater. Background technique [0002] The working principle of the wall-mounted heater is that the gas and air enter the gas mixing chamber to mix, and then enter the combustion chamber in the heat exchanger for combustion. The heat generated by the combustion helps the coil in the combustion chamber to heat. The coil is located in the annular space of the combustion chamber. The fluid flows through the coil, the fluid takes away the heat, and flows through the fluid pipes installed in the room. When the indoor air flows through the fluid pipes, it will take away the heat on the fluid pipes, thereby increasing the indoor temperature. . Correspondingly, the temperature of the fluid gradually decreases, and then flows back to the wall-mounted heater to be heated again, and then enters the fluid pipe with heat to help heat the air i...
