Embodiment
The technical solution of the utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
It is shown in Figure 1, a kind of Shell-tube Condenser with flow apron, including extend transversely and there is middle cavity
Housing 1, two tube sheets 2 for being respectively arranged at the two ends of housing 1, many heat exchanger tubes 3 being connected between two ends tube sheet 2.On housing 1
Portion is provided with refrigerant inlet pipe 4, bottom and is provided with refrigerant outlet pipe 5, and refrigerant vapour is flowed into from refrigerant inlet pipe 4
In condenser, carry out after heat transfer, then flowed out from refrigerant outlet pipe 5 with the external contact of heat exchanger tube 3 within the condenser.Its
In, air flap 6 is provided with below the port of export of refrigerant inlet pipe 4, to prevent the refrigerant vapour of high speed from causing heat exchanger tube 3
Damage, while change refrigerant vapour flow direction so that it fully flows and carried out in the inner chamber of housing 1
Heat exchange.
It is shown in Figure 2, air flap 6 include extend transversely lagging 61, be connected to lagging 61 and refrigerant
Perpendicular baffle plate 62 between the port of export of inlet tube 4, it is divided into two pieces of wind deflectors 64 at the two ends of lagging 61, is opened in lagging respectively
61 both ends and two air guide holes 63 run through along the vertical direction.In the present embodiment, air guide hole 63 is in the following way
Formed：The both side ends of lagging 61 offer U-shaped breach, and wind deflector 64 is regularly located at the openend of U-shaped breach, wind-guiding
Just air guide hole 63 is formd between plate 64 and U-shaped breach.
Shown in Figure 2, the length bearing of trend of the wind deflector 64 of both sides is arranged in an oblique way with lagging 61 respectively, wind-guiding
The upper end of plate 64 is along the vertical direction less than perpendicular baffle plate 62 so that the part of refrigerant steam energy entered through refrigerant inlet pipe 4
Enough tops from wind deflector 64 reach the left and right sides region of air flap 6；Wind deflector 64 is simultaneously along horizontal stroke between perpendicular baffle plate 62
