Abstract
The invention discloses a heat exchanger air inlet buffer structure which comprises an air inlet and a flow guide plate on the lateral cylinder wall of a replacement section, wherein the air inlet is a rectangular conical tube which is large in inner part and is small in outer part; a flange is installed at the small end of the rectangular conical tube, and the other end of the rectangular conical tube is connected with the cylinder wall of the replacement section in a seal mode; the flow guide plate is a middle-placed bending angle plate; an outer protruding bending seam is outward and is coaxially connected with the replacement section in a seal mode; the middle-placed flow guide plate forms a frontage protective screen which plays a role of buffer; and additionally, two diffusion-shaped channels are formed between two sides of the flow guide plate and the rectangular conical tube, and the diffusion-shaped channels and the cylinder wall of the replacement section transit naturally so as to form a speed-reduction and pressure-reduction structure. According to the invention, through the additional arrangement of the buffer structure at the air inlet and the change of the diffusion-shaped channels at two sides, the frontage of a heat exchange tube is prevented from being impacted by air flows, and the heat exchange elements are prevented from being damaged.
Description
Technical field
The present invention relates to a kind of heat exchanger structure and improve, specifically, the present invention relates to a kind of heat exchanger inlet structure and improve.
Background technology
Heat exchanger is the Traditional industrial product, in manufacturing industry, uses very general.The heat exchanger air inlet of prior art is a straight pipe, and this is simple in structure, easy to manufacture, can satisfy the Hot swapping condition.But, make the compressed air pressure of Hot swapping when big, inevitable frontal impact inner-heating tube, powerful wind-force are blown over and are prone to cause heat exchanger tube distortion and heat exchanger tube and tube plate expanded-connecting place to become flexible, even cause fracture damage.Heat exchange element in the heat exchanger is in case damage certainly will destroy the Hot swapping condition, and maintenance, replacing all can cause economic loss.
Summary of the invention
The present invention is primarily aimed at the deficiency of prior art; A kind of heat exchanger air inlet buffer structure is proposed; This structure be outer little in big rectangle Taper Pipe, be provided with deflector in the pipe, the source of the gas of introducing gets into from air inlet; After deflector both sides curved wall diffusion step-down, both slow down impulsive force, increased heat exchanger effectiveness again.
The present invention realizes technical goal through following technical proposals.
Heat exchanger air inlet buffer structure, it comprises air inlet and the deflector that is fixedly connected on the displacement section side tube-wall.Its improvements are: said air inlet is interior big outer little rectangle Taper Pipe, and flange is located at rectangle Taper Pipe small end, and the other end is tightly connected with displacement section barrel.Said deflector is bent into gusset between two parties by rectangular slab, and the evagination bending is stitched outwardly, constitutes the front barrier at the coaxial deflector that is tightly connected placed in the middle of displacement section barrel, constitutes the passage of two diffusion types between deflector both sides and the rectangle Taper Pipe inwall.
Deflector in the said structure is bent into 90 °～120 ° gusset.
The present invention compared with prior art has following good effect:
1, the built-in deflector placed in the middle of rectangle Taper Pipe constitutes the front barrier, forms the passage of both sides diffusion type naturally, and this is simple in structure, makes easily;
2, compressed air step-down behind diffusion type passage reduction of speed is obvious, slows down impulsive force through the refraction of displacement section inwall again, significantly reduces destructiveness.
3. deflector plays barrier action, alleviates air-flow frontal impact heat exchanger tube, avoids being damaged.
Description of drawings
Fig. 1 is that structure master of the present invention looks sketch map.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the A-A profile of Fig. 1, shows 3 jiaos of curved shapes of deflector among the figure.
The specific embodiment
According to accompanying drawing and combine embodiment, the present invention is described further below.
Heat exchanger air inlet buffer structure shown in Figure 1, it comprises air inlet and the deflector 3 that is fixedly connected on displacement section 4 side tube-walls.Said air inlet is interior big outer little rectangle Taper Pipe 1, and outer flange connecting 2 is located at rectangle Taper Pipe 1 small end, and the other end is tightly connected with displacement section 4 barrels.Fig. 3 and deflector shown in Figure 23 are bent into gusset between two parties for rectangular slab, and present embodiment is bent into 120 ° gusset, and the evagination bending is stitched outwardly, and 4 barrels are coaxial is tightly connected in the displacement section, and deflector 3 formation front barriers placed in the middle play cushioning effect.In addition, constitute two diffusion type passages between deflector 3 both sides and rectangle Taper Pipe 1 inwall, the diffusion type passage constitutes the reduction of speed buck configuration with the transition of displacement section 4 barrels nature.The present invention can be alleviated air-flow frontal impact heat exchanger tube through setting up buffer structure at air inlet and making both sides diffusion type passage into, avoids heat exchange element to be damaged.
Claims (2)
1. heat exchanger air inlet buffer structure, it comprises air inlet and the deflector (3) that is fixedly connected on displacement section (4) side tube-wall; It is characterized in that: said air inlet is interior big outer little rectangle Taper Pipe (1), and flange (2) is located at rectangle Taper Pipe (1) small end, and the other end is tightly connected with displacement section (4) barrel; Said deflector (3) is bent into gusset between two parties by rectangular slab; Evagination bending seam outwardly; Constitute the front barrier at the coaxial deflector placed in the middle (3) that is tightly connected of displacement section (4) barrel, constitute the passage of two diffusion types between deflector (3) both sides and rectangle Taper Pipe (1) inwall.
