Abstract
The utility model relates to a double-tube-plate type heat exchanger, which mainly solves the problem in the prior art that existing heat exchangers are not in place in welding so as to cause the leakage and the cross pollution of medicaments. The double-tube-plate type heat exchanger comprises a heat exchange tube, and outer and inner tube plates arranged on the outside of the heat exchange tube. The utility model is characterized in that the inner tube plate is expanding joint with the heat exchange tube and the outer tube plate is in welding joint with the heat exchange tube. Upon the completion of the expanding joint of the inner tube plate and the welding joint of the tube plate, the middle section of the seamless heat exchange tube is exposed to the outside and is used as a leakage detection port. Meanwhile, during the leakage of medicaments, the cross infection between two medicaments is avoided, and polluted sites can be visually detected. In addition, the double-tube-plate type heat exchanger is convenient to clean.
Description
Technical field
The utility model relates to a kind of heat exchanger, is specifically related to a kind of double tube plate heat exchanger.
Background technology
At present, Dual-tube heat exchanger is generally used on market, but general double tube plate heat exchanger is often due to expand tube stress or weld the leakage problem that causes not in place, easily causes drug leakage, medicine cross pollution.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of double tube plate heat exchanger, and main Welding of Heat-exchanger is not in place at present, easily causes the problem of drug leakage, medicine cross pollution.
The technical scheme that the utility model adopts is: a kind of double tube plate heat exchanger, comprise heat exchanger tube and the outer tube plate, the internal tube plate that are arranged on heat exchanger tube outside, and described internal tube plate and heat exchanger tube are expanded joint, described outer tube plate and heat exchanger tube are welding.
The port that described internal tube plate is connected with heat exchanger tube is provided with expanded joint groove.
Described expanded joint groove is " bow " font.
The beneficial effects of the utility model are: owing to taking technique scheme, carry out internal tube plate expanded joint and outer tube plate welding, centre has one section of seamless heat exchanger tube outside exposed, as leak detection mouth and played leakage and can not allow two kinds of medicine cross-infections, can visual inspection to points of contamination, and be convenient to clean.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, a kind of double tube plate heat exchanger, comprises heat exchanger tube 3 and the outer tube plate 1, the internal tube plate 2 that are arranged on heat exchanger tube 3 outsides, and described internal tube plate 2 is expanded joint with heat exchanger tube 3, and described outer tube plate 1 is welding with heat exchanger tube 3.
Internal tube plate 2 and heat exchanger tube 3 expanded joints, according to the heat exchanger tube of previous making 3 and the expanding joint process of internal tube plate 2, carry out expanded joint, control as requested again the distance between outer tube plate 1 and internal tube plate 2, for outer tube plate 1 and heat exchanger tube 3, weld, the welding stress and the expanded joint stress that by such front and back, sequentially improve heat exchanger tube 3, outer tube plate 1 and internal tube plate 2 reduce, and have realized minimizing leakage phenomenon, prevent medicine cross-infection, and can visual inspection to points of contamination, and be convenient to clean.
Preferred version of the present utility model: the port that described internal tube plate 2 is connected with heat exchanger tube 3 is provided with expanded joint groove 4.
Preferred version of the present utility model: described expanded joint groove 4 is " bow " font.
Every technical staff's notice: although the utility model describes according to the above-mentioned specific embodiment; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
Claims (3)
