Description
Technical field
The present invention relates to a kind of heat exchanger of fuel wall hanging formula radiator, belong to the optimisation technique of radiator.
Background technology
During the operation principle of wall-mounted radiator, combustion gas and air are mixed into gas mixing chamber, are entered back into heat exchanger
Combustion chambers burn, burning produce heat help combustion chamber in coil pipe heating, coil pipe be located at combustion chamber annular space in,
Fluid flows through out of coil pipe, and fluid takes away heat, flows through the fluid line being arranged in room, and indoor air flows through fluid
During pipeline, the heat on fluid line can be taken away, so as to play a part of improving indoor temperature.Accordingly, the temperature of fluid
Gradually reduce, then flow back into wall-mounted radiator and be heated again, then entering back into fluid line with heat helps to heat room
Interior air, so moves in circles, until indoor air is heated to suitable temperature.
Gather polylith fin in combustion chamber, and heating tube passes through fin, and the heat that fuel gas buring is produced is absorbed by fin, or logical
Cross fin clearance to flow to the direction of outlet flue from the entrance point of combustion chamber, the unbalanced situation of heat is there is between fin.Mesh
The fin of preceding some radiators, is conformed with fin walls, and advantage is the contact area for having increased heating air-flow and fin, no
Foot is that the unbalanced situation of heat between fin does not still change.
Respectively there is a fix bar in former and later two outsides of top of combustion chamber, and existing fix bar generally uses L-type structure, heat
Exchanger can produce some concussions, the fixed rod support insufficient strength of L-type, heat exchanger during supercharging and decompression, all
Metal fatigue is easily produced in shaking repeatedly, life of product is influenceed.
Support feet on first member plate and right end plate on same seamed edge not in one plane, not only processing difficulties, Er Qiexu
The material wanted is more, installs also increasingly difficult.
It is, thus, sought for a kind of fixed rod support intensity is more preferably, the heat exchanger being easily installed.

Mixing chamber, a side wall of triangular prism are close to the mode screw of outer wall of combustion chamber by fix bar and the bottom wall of gas mixing chamber
Tighten together, the inner chamber of gas mixing chamber is communicated with the inner chamber of combustion chamber.
Heat exchanger can produce some concussions during supercharging and decompression, all, and fix bar is made up of two parts, and two
Surplus between individual part can just eliminate a part of concussion, mitigate metal fatigue caused by concussion, extend the use longevity of product
Life.Also, the fix bar of triangle is more stronger than the ability that the fix bar of L-type bears concussion, and service life is longer.
First member plate 2 outwards turns down to form the upper left vertical with first member plate with two sides of the axis parallel of heat exchanger
Support feet 21 and lower-left support feet 22, same side turn down the upper left support feet 21 to be formed and lower-left support feet 22 in same
On tangent plane；Right end plate 3 outwards turns down to form the upper left vertical with first member plate with two sides of the axis parallel of heat exchanger
Support feet 31 and lower-left support feet 32, same side turn down the upper left support feet 31 to be formed and lower-left support feet 32 in same
On tangent plane.So make production more simple, materials are reduced, the structure of the part being fixed on accordingly in these support feets is also more
Simply.
Right cover plate is provided with right end plate, water inlet 5 and delivery port 6 be located on right cover plate, water inlet 5 be provided be used for
