The specific embodiment
Below, with reference to the thermal insulator that be used for reflux of accompanying drawing detailed description according to one embodiment of the invention.At first, in the drawings, to identical inscape or the identical symbol of member mark.
As shown in Figures 1 to 3, the present invention roughly comprises heat-insulating material 100, crust 200, installation unit 300.
At first, heat-insulating material 100 is described.In the manufacturing engineering of printed circuit board wiring substrate, for at the top of printed circuit board wiring substrate mounting electronic parts to weld, the temperature of the heating furnace in the reflux is heated into about 200 ℃, in the process that keeps described temperature, the effect of the inside and outside heat exchange of heating furnace is cut off in described heat-insulating material performance.Generally, the heat-insulating material made of the described heat-insulating material manufacture method that can use short fiber in glass fibre to add behind the bonding agent mineral wool by compression forming.But described bonding agent is decomposed by temperature easily and has image problem at random, therefore, more preferably uses by the long stapled heat-insulating material in the manufacture method weaving glass fiber of glass fibre, does not use bonding agent.The heat-insulating material of the manufacture method manufacturing by described glass fibre has, and that fiber itself does not have is intensive, scattering etc., and thermal insulation and heat insulating ability are outstanding, the advantage low in the pollution of the environment that causes because of dust etc.
Then, crust 200 is described.Described crust 200 encases described heat-insulating material 100.Namely, described crust 200 forms the various shapes such as sack or paper bag shape so that section puts into described heat-insulating material 100 easily within it, in described crust 200, put into after the described heat-insulating material 100 stitching such as available securing member, magnet, magic tape, pressure sensitive adhesive double coated, double buckle, hook, knot or special sewing line and making.Described crust 200 prevents the long-time deteriorated and phenomenon of scattering of described heat-insulating material 100, and performance improves the effect of insulation and insulation effect.When using described heat-insulating material 100 separately, because the circulation of air, the heat waste of reflux inside fails to keep an appointment 50%, if but encase described heat-insulating material 100 with described crust 200, then heat loss rate can ease down to approximately less than 5%.
Described crust 200 is preferably by the glass fibre manufacturing, and making described crust 200 with glass fibre is that thermal conductivity is below 1, thereby effectively cuts off the circulation of air because the heat resisting temperature of glass fibre reaches 800 ℃ approximately.
In addition, silicon compound is preferably further contained in the upper end of described crust 200.Described silicon compound is by silica and prestox cyclisation tetrasiloxane and consist of, with respect to the gross weight of described crust 200 upper ends, the amount of described silica and prestox cyclisation tetrasiloxane is that described silica is about 10 to 20Wt%, described prestox cyclisation tetrasiloxane about 0.1 is to 1Wt%.When containing described silicon compound with described ratio, conduct heat or be diathermanous in the upper end of so-called described crust 200 that can more effectively prevent the opposing face of the contact-making surface by reflux.
And the thickness of described crust 200 is preferably made into about 10 to 30mm.This is because most effectively performance is incubated and insulation effect on described thickness.
And, can further comprise heat preservation component 210 for increasing insulation effect at described crust 200.Described heat preservation component 210 is installed in the inside of sack after described crust 200 forms sack 220, by applicable described heat preservation component 210, suitably select thickness and the kind of described heat preservation component 210 according to the temperature profile of the part that will weld, thereby can provide best insulation and insulation effect to described crust 200.Described heat preservation component 210 can utilize by accumulation of heat the various materials that can have as the thin film heater of power supply function etc. heating function, when needing further to improve holding temperature, described heat preservation component 210 can further be set and use.
And, further comprise the mutual attaching parts 230 of thermal insulator that are used for reflux for connecting at described crust 200.Described attaching parts 230 can be used the various materials such as securing member, magnet, magic tape, pressure sensitive adhesive double coated, double buckle, hook, knot, by using described attaching parts 230, eliminate describedly for the mutual interval of the thermal insulator of reflux, and have the heat that can more effectively prevent from heating furnace discharging.
In addition, described installation unit 300 is arranged on described crust 200 and can easily installs and dismantle described heat-insulating material 100 in order to carry out at the substrate mounting parts on the reflux of welding engineering.Described installation unit 300 can use the general employed various installation units such as securing member, magnet, magic tape, pressure sensitive adhesive double coated, double buckle, hook, knot.
In addition, as shown in Figure 4, the present invention further comprises air inflow section 400, air outflow section 500 and ventilation adjusting portion 600.
Described air inflow section 400 runs through described and forms for the thermal insulator of reflux in order to extraneous air is flowed into reflux.And described air outflow section 500 runs through described and forms for the thermal insulator of reflux so that from reflux discharging inner air.That is, when the heating furnace of rapid cooling and reflux device, described air inflow section 400 and described air outflow section 500 flow into rapidly the low temperature extraneous air, and discharge rapidly the inner air of high temperature as the movable passageway of air.
And ventilation adjusting portion 600 forms by open and close and reversibly cuts off the extraneous air that flow into reflux or the structure of the inner air that flows out from described reflux.Described ventilation adjusting portion 600 is reversible opening/closing units, in the thermal insulator for reflux of the present invention, during by air inflow section 400 inflow air or from air outflow section 500 discharged air, open described ventilation adjusting portion is closed described ventilation adjusting portion when the inflow of cut-out air and discharging.Most preferably in the thermal insulator that is used for reflux with slide fastener separably in conjunction with the part corresponding to air inflow section 400 or air outflow section 500, but also can utilize the various installation units such as securing member, magnet, magic tape, pressure sensitive adhesive double coated, double buckle, hook, knot.
More than, at accompanying drawing and specification most preferred embodiment has been described.Herein, although used specific term, these terms only are used for illustrating the present invention, do not limit the scope of the present invention of putting down in writing in implication or the claim scope.Therefore, it is contemplated that so long as those skilled in the art can carry out various distortion or impartial enforcement thus.And real technical protection scope of the present invention should be determined by the technological thought of claim scope.
