Detailed description of the invention
As shown in Figure 1 to 4, this utility model includes housing and the front end tube sheet 9 being arranged in housing, rear end tube sheet
10；The front-end and back-end of housing are respectively arranged with front-end pipe box 1 and rear end header 4；Heat exchanger tube 7 and heat exchange wing it is provided with in housing
Sheet 6, the upper side and lower side of housing is respectively arranged with epipleural 2 and lower side panel 3；Heat exchanger tube 7 is parallel to upper and lower side plate, heat exchange wing
Sheet 6 is perpendicular to heat exchanger tube 7；Heat exchanger tube 7 and heat exchange fin 6 are many groups；Often group heat exchange fin 6 is inserted in heat exchanger tube 7 respectively, changes
Heat pipe 7 and heat exchange fin 6 form tube bundle；Front end tube sheet 9 and rear end tube sheet 10 are inserted in heat exchanger tube 7 respectively, by epipleural 2
It is fixed with lower side panel 3；Again the bobbin carriage of tube bundle Yu two ends is welded together and just constitute a complete gas cooling
Device.
The two ends of heat exchanger tube 7 are welded and fixed are connected with front-end pipe boxes 1 and rear end header 4 respectively；Rear end header 4 and rear end pipe
