Side wall at left and right sides of the blower bottom end is provided with outside flange II, and the side wall before and after bottom end is provided with
Downward extension board is provided with inside amplification muscle on the extension board.
The flange I is tightly connected with flange II, and prolonging before and after blower is arranged in heat exchanger top front-rear side walls
Stretch in plate, and with the amplification muscle interference fit seal.Distance i.e. between extension board is greater than between the front-rear side walls of heat exchanger top
Distance, play the role of guiding to the installation of heat exchanger, heat exchanger top front-rear side walls allowed to be quick installed at blower
Assembly efficiency is effectively improved in bottom end；Inside amplification muscle is matched with heat exchanger top front-rear side walls using interference on extension board
It closes, improves the leakproofness of heat exchanger and blower.
Further, being provided with mounting hole I on the flange I, it is provided with mounting hole II on the flange II, bolt is worn
It crosses the mounting hole I and mounting hole II connects the flange I and flange II, fixed flange I and flange II, i.e. stationary heat exchangers
And blower, it has been convenient for the installation and removal of exchanger and blower.
Further, the left and right sidewall of the flange II and blower housing is integrally formed, the extension board and amplification muscle
It is integrally formed with the front-rear side walls of blower housing.
The utility model has the beneficial effects that the heat exchanger top front-rear side walls of the utility model are mounted on before and after blower
In extension board, and with amplification muscle interference fit seal, play guiding role in assembling process, effectively improve assembly efficiency；With
This is bolted flange I and flange II, and then stationary heat exchangers and blower simultaneously, has been convenient for heat exchanger and blower
Installation and removal；After the assembly is completed, smoke evacuation system good airproof performance, it is ensured that oxygen needed for providing enough fuel gas burings, burning
Operating condition is good, and fume indication is stablized.
