Abstract
The utility model discloses a kind of cooler leakproof and be in the charge of plate, this is in the charge of plate and comprises and be in the charge of plate body, described being in the charge of on plate body is provided with several tubesheet holes, the aperture of described tubesheet holes is provided with chamfering, is provided with the cannelure be in the charge of described in be sealedly connected on by cooler copper tubes on plate body in the middle part of the inwall of described tubesheet holes.Compared with tube sheet groove of the prior art, of the present utility model be in the charge of plate utilize cannelure can with cooling copper tube compact siro spinning technology, through power plant's actual use repeatedly, can effectively prevent from leaking.When being in the charge of plate and left and right hydroecium, fagging, cooling tube, fin etc. and forming cooler, after adopting mechanical means to carry out overall time expand tube, close contact, thermal resistance is little, and heat transfer property is excellent.
Description
Technical field
The utility model relates to a kind of cooler leakproof and is in the charge of plate.
Background technology
Being in the charge of plate is major part in aerial cooler, is provided with multiple hole for being connected with the heat-exchange tube of cooler being in the charge of on plate.Weigh the quality of a cooler quality, the sealing of being in the charge of plate and cooling copper tube and the pulling-out force that can bear are two important technology indexs.
Sealing of being in the charge of plate and cooling copper tube of the prior art needs further to improve, and effectively could increase service life and the service efficiency of aerial cooler.
Utility model content
The technical problems to be solved in the utility model overcomes existing defect, provides a kind of cooler leakproof to be in the charge of plate.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
Plate is in the charge of in a kind of cooler leakproof, comprises and is in the charge of plate body, when the material being in the charge of plate body be iron etc. get rusty easily material time, need to arrange zinc coat at the upper surface being in the charge of plate body, after zinc-plated, do Passivation Treatment.The thickness of zinc coat is generally 20 ~ 40 μm, and preferably, the thickness of zinc coat is 30 μm.Certainly, when being in the charge of the material that plate body adopts copper etc. not easily to get rusty, zinc coat can omit.
Described being in the charge of on plate body is provided with some tubesheet holes, the aperture of described tubesheet holes is provided with chamfering, the orifice chamfer of described tubesheet holes is 45 ° × 0.5 ~ 1.5mm, and the inwall of described tubesheet holes is provided with 1 ~ 2 cannelure be in the charge of described in be sealedly connected on by cooler copper tubes on plate body.The concrete number of cannelure, depending on being in the charge of the thickness of plate body, does trisection in the middle part of the inwall that cannelure can be arranged on tubesheet holes or by the inwall of tubesheet holes.
The wall of described tubesheet holes requires smooth, can not have the axial groove more than 0.1mm.
Further, the diameter of described tubesheet holes 1 ~ 2mm less of the diameter of described cannelure.
Preferably, the diameter of tubesheet holes is 16.8mm, hole depth 30mm; The number of described cannelure is 1, and groove depth is 0.5mm, and width is 4mm.
Compared with tube sheet groove of the prior art, of the present utility model be in the charge of plate utilize cannelure can with cooling copper tube compact siro spinning technology, through power plant's actual use repeatedly, can effectively prevent from leaking.When being in the charge of plate and left and right hydroecium, fagging, cooling tube, fin etc. and forming cooler, after adopting mechanical means to carry out overall time expand tube, close contact, thermal resistance is little, and heat transfer property is excellent.
