Abstract
The invention provides a combination method for a phase-change radiator of an industrial and mining lamp. The combination method includes electroplating nickel on a connecting surface of the radiator and connecting the nickel-plated connecting surface with a light source of the industrial and mining lamp by a soldering mode. Welding flux only contains tin in soldering procedures, the welding temperature is 380 DEG C, and the welding time is within a range of 5 seconds. The invention further provides a combination structure for the phase-change radiator of the industrial and mining lamp. The combination structure comprises the connecting surface of the radiator, a nickel layer and a soldered layer. The connecting surface of the radiator is sequentially connected with the nickel layer and the soldered layer, and the soldered layer is connected with the light source of the industrial and mining lamp.

Background technology
Existing bulkhead lamp capable radiator is all to adopt on radiator, to smear after heat-conducting cream with the connected mode between light source, by the mode of screw, both is combined.But the method makes to exist between radiator and light source multilayer thermal resistance, and there will be the gap on certain top, cause the heat of light source can not pass timely and effectively guide radiator, to radiator cannot be dispelled the heat to light source in time, had a strong impact on light fixture service life.
Summary of the invention
The above-mentioned defect and the problem that exist with the connected mode between light source for existing bulkhead lamp capable radiator, the object of the embodiment of the present invention is to provide a kind of combined method that reaches efficient, simple, bulkhead lamp capable light source can be passed in time, to greatest extent to the bulkhead lamp capable phase-change heat sink of radiator.
In order to achieve the above object, the invention provides following technical scheme:
A combined method for bulkhead lamp capable phase-change heat sink, comprises the following steps:
1) in the enterprising electroplating nickel plating of radiator, the position of described nickel plating is the joint face of radiator and bulkhead lamp capable light source;
2) by soldering mode, the nickel plating joint face of radiator described in step 1) is connected with bulkhead lamp capable light source, in described soldering process, scolder only comprises tin, and welding temperature is 380 ℃, and weld interval is in 5 seconds.
Scolder does not comprise other compositions, has guaranteed to only have nickel and two kinds of heat-conducting metals of tin in the joint face of bulkhead lamp capable light source and radiator, there is no other residual impurities, can not affect the thermal conductivity between bulkhead lamp capable and radiator.Adopt the welding temperature of 380 ℃ can guarantee that tin has good mobility, can exactly the nickel plating joint face of radiator and bulkhead lamp capable light source be coupled together within a short period of time.
The present invention also provides a kind of combining structure of bulkhead lamp capable phase-change heat sink, comprise radiator joint face, nickel dam and soldering layer, described radiator joint face is connected with nickel dam, soldering layer successively, described soldering layer connects bulkhead lamp capable light source simultaneously, the thickness of described nickel dam is 1-3um, and the thickness of described soldering layer is below 1um.
Concrete, the thickness of described nickel dam is 3um, the thickness of soldering layer is 0.5um.
Further technical scheme, square, circular or other shapes of being shaped as of described nickel dam.
Combined method provided by the invention is by the mode of nickel plating, soldering, make to be only connected by nickel and the tin with excellent heat-conducting function between light source and radiator, efficiently solve the problem of loose contact between bulkhead lamp capable light source and radiator, reduce thermoresistance layer, make heat of light source guide radiator faster, improved light fixture service life.The combining structure of bulkhead lamp capable phase-change heat sink provided by the invention, the thickness of its nickel dam is 1-3um, the nickel dam of this thickness, meeting internuncial while of light source and radiator, has guaranteed good thermal conductivity.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the combining structure of bulkhead lamp capable phase-change heat sink in the present invention.
The specific embodiment
Below in conjunction with accompanying drawing of the present invention, technical scheme of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The combined method of bulkhead lamp capable phase-change heat sink of the present invention, comprises the following steps:
1) in the enterprising electroplating nickel plating of radiator, the position of described nickel plating is the joint face of radiator and bulkhead lamp capable light source;
2) by soldering mode, the nickel plating joint face of radiator described in step 1) is connected with bulkhead lamp capable light source, in described soldering process, scolder only comprises tin, and without other compositions, to solder flux also no requirement (NR), welding temperature is 380 ℃, and weld interval is in 5 seconds.
By the nickel plating of joint face, make radiator can realize and being connected by cheap soldering mode with the joint face of bulkhead lamp capable light source.The fusing point of soldering is low, be connected firmly, simple to operate, simultaneously, the heat conductivility of nickel and tin is all fine, by nickel plating and scolding tin, make to be only connected by nickel and these two kinds of metal materials of tin with excellent heat-conducting function between light source and radiator, reduce thermoresistance layer and space, improve thermal conductance, and do not need by connected modes such as screws, avoided the operation of punching, docking and assembling, production efficiency is provided.
The present invention also provides a kind of combining structure of bulkhead lamp capable phase-change heat sink, as Fig. 1, comprises radiator joint face, nickel dam and soldering layer, and radiator joint face is connected with nickel dam, soldering layer successively, and soldering layer connects bulkhead lamp capable light source simultaneously.The thickness of nickel dam can be 1-3um, and the thickness of soldering layer is below 1um.Preferably, in embodiment, adopt the nickel dam that thickness is 1-3um, the soldering layer that thickness is 0.5um.According to the size of the connection area of bulkhead lamp capable light source, can according to actual needs the scope of nickel plating be arranged to square, circular or other shapes.The shape that is nickel dam, soldering layer can be square, circular or other shapes.
In the combining structure of this bulkhead lamp capable phase-change heat sink, nickel dam is mainly for meeting being connected of light source and radiator, and the thickness of nickel dam arranges very littlely, can also guarantee that combining structure has thermal conductive resin.In addition, heat conductivility and the nickel of tin are similar, but its fusing point is relatively low, and therefore the Thickness Ratio nickel dam of soldering layer is less, thereby make combining structure in the time connecting light source and radiator, and its stability, fastness and security are optimized more.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, any be familiar with those skilled in the art the present invention disclose technical scope in; can expect easily changing or replacing, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should described be as the criterion with the protection domain of claim.
