Fig. 2 is a structural representation of the present invention.
Fig. 3 is user mode figure of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As Fig. 1 ~ shown in Figure 3: the present invention includes seal body 1, first adjustment hole 2, second adjustment hole 3, the portion 4 of dehiscing, clamping force 5, upper cover plate 6, fin 7, dividing plate 8, hot limit radiating part 9, lower cover 10, locating hole 11 and cold limit radiating part 12.
As depicted in figs. 1 and 2: in order to guarantee the brazing quality of plate fin type heat exchanger, strip of paper used for sealing comprises seal body 1, is provided with the locating hole 11 of perforation in the described seal body 1, and the axis of the axis of described locating hole 11 and seal body 1 is located along the same line.Two portions 4 of dehiscing are arranged, at the openend of two 4 formation locating holes 11 of portion of dehiscing on the seal body 1 of locating hole 11 sides; The described portion 4 of dehiscing expands outwardly, and the spacing of the end of two portion's 4 close openends of dehiscing is greater than two spacings of portion 4 near the end of locating holes 11 of dehiscing.After the end of seal body 1 is provided with the portion 4 of dehiscing, when seal body 1 assembles in core body, under the effect of clamping force 5, the compression and back elastic force and the clamping force 5 of portion 4 of dehiscing balances each other, and helps seal body 1 is compressed the control weld gap, improve core body soldering qualification rate, solderability is good.
Described locating hole 11 comprises first adjustment hole 2 and second adjustment hole 3, and described first adjustment hole 2 is positioned at seal body 1, the first adjustment hole 2 and is connected with second adjustment hole 3, and first adjustment hole 2 runs through in the seal body 1; Second adjustment hole 3 is the openend of locating hole 11.First adjustment hole 2 is rounded, and second adjustment hole 3 is splayed; First adjustment hole 2 and second adjustment hole 3 are all along the width distribution of seal body 1.When the portion of dehiscing 4 of seal body 1 compressed under clamping force 5 effects, the portion of dehiscing 4 of seal body 1 inwardly shrank the back and becomes rectangular-shaped.
The middle part of seal body 1 is provided with first adjustment hole 2, makes the middle part of seal body 1 hollow, and thermal capacity is little, and contraction distortion is little, and thermal stress is even, with the good welding performance of peripheral thin-walled connector, and soldering qualification rate height, good product quality.Simultaneously, the middle part of seal body 1 is hollow, has alleviated the weight of strip of paper used for sealing, thereby has alleviated the weight of heat exchanger core body, has also just alleviated the weight of heat exchanger entire product, has saved the soldering power consumption, has all reduced product cost from weight and power consumption angle.
As shown in Figure 3: be user mode figure of the present invention; It also is the core schematic diagram of plate fin type heat exchanger.Described core body comprises the upper cover plate 6 and the lower cover 10 of symmetrical distribution, and upper cover plate 6 is positioned at the top of lower cover 10.10 of upper cover plate 6 and lower covers are provided with alternatively distributed hot limit radiating part 9 and cold limit radiating part 12, described cold limit radiating part 12 comprises fin 7, the two ends of described fin 7 are provided with the seal body 1 of symmetrical distribution, and described seal body 1 is corresponding to all contiguous fin 7 of the openend that locating hole 11 is set; Hot limit radiating part 9 comprises hot edge channel strip of paper used for sealing, and hot limit radiating part 9 is provided with dividing plate 8 with the joint portion of cold limit radiating part 12; The shape of seal body 1 is corresponding with the shape of fin 7 and dividing plate 8.Under the effect of clamping force 5, hot limit radiating part 9 and cold limit radiating part 12 are pressed on 10 of upper cover plate 6 and lower covers, because seal body 1 has the portion of dehiscing 4 of outside protrusion, seal body 1 and dividing plate 8 simple weld gaps are reduced.Core body after the assembling places soldering oven to heat, under high temperature action, brazing solder layer scorification on the dividing plate 8, the scolder of molten condition is under the acting in conjunction of surface tension and siphonage, fill up each weld gap by infiltration phenomenon, after the cooling cooling, the core body that several parts are formed has just formed an integral body attractive in appearance.
Be provided with the locating hole 11 of perforation in the seal body 1 of the present invention, locating hole 11 comprises first adjustment hole 2 and second adjustment hole 3, first adjustment hole 2 is positioned at the middle part of seal body 1, make seal body 1 be the hollow setting, alleviate strip of paper used for sealing weight, thereby alleviated the weight of heat exchanger core body, also just alleviated the weight of heat exchanger product, save the soldering power consumption, reduced the cost of product; After seal body 1 hollow was provided with, thermal capacity was little, and contraction distortion is little, and thermal stress is even, with the good welding performance of peripheral connector, and soldering qualification rate height, good product quality.When seal body 1 assembles in core body, under the effect of clamping force 5, the compression and back elastic force and the clamping force 5 of the portion 4 of dehiscing balance each other, and are beneficial to compress, the control weld gap, so the core body solderability is good, soldering qualification rate height, simple and compact for structure, easy to install, with low cost, applied widely, safe and reliable.
