Description
Technical field
The utility model relates to the low temperature compartment heat abstractor of a kind of internal work under low temperature environment, relates in particular to a kind of active low temperature water-proof radiator.
Background technology
As everyone knows, waterproof technique is penetrated into each details in the life always.Water-proof watch in the daily life, waterproof camera, waterproof eyeglasses, even to the submarine of national defense industry are without impermeable waterproof technique and device.Under different occasions, needed classification of waterproof is different.For traditional compartment, mostly adopt rubber seal to seal, thereby play the effect of waterproof, but can find in actual applications, under the exigent environment of some classification of waterproof, can't play good waterproof effect.Particularly under low temperature environment, the refrigeration device surface can be excessively low because of temperature, thereby the moisture in the condensation air produces " dewfall " phenomenon, and then affect the working life of device, even can cause the dysfunction of assembly.And, traditional compartment, mostly can only be in the less demanding situation of classification of waterproof waterproof, but can't stop air to enter, yet contain moisture in the air, certainly will the waterproof effect of compartment be exerted an influence.
A standard atmospheric pressure approximates 1.013 * 10^5 Pa, and it is high to be equivalent to the 76cm mercury, and more directly perceived is exactly the water-column that approximates 10.33m.Atmospheric pressure is very large, and is objective reality, and famous " experiment of horse Debao hemisphere " just can illustrate this problem.Thereby, for a compartment, being placed on the not water inlet of working in the water, but it is just necessarily fine not represent in air its sealing.We know that in the situation of low temperature, the gas molecule random motion of compartment inside weakens, thereby cause air pressure inside to reduce, thereby can produce very large pressure difference between the compartment inside and outside, more are beneficial to air and enter compartment inside.And traditional compartment, adopt rubber ring as seal member, in actual applications, we then need the rubber washer for the tailor-made different size of different compartment, cause the waste of financial resource and material resource.
The utility model content
The purpose of this utility model is to provide a kind of active low temperature water-proof radiator, and this active low temperature water-proof radiator is simple in structure, cost is low, easy to use, and waterproof effect and fine every the air effect is convenient to practical application.The utility model also provides a kind of preparation method of active low temperature water-proof radiator, the preparation method of this active low temperature water-proof radiator is simple to operate, the active low temperature water-proof radiator of made is simple in structure, cost is low, easy to use, waterproof effect and fine every the air effect is convenient to practical application.
For realizing above-mentioned technical purpose, the technical scheme that the utility model is taked is: a kind of active low temperature water-proof radiator comprises radiator, semiconductor cooler, thermistor and compartment; It is characterized in that: described compartment comprises and also comprises lid at the bottom of integrated box body and the box; Described lid is arranged on the opening of described box body by the latex sealing; Be provided with through hole at the bottom of the described box; Described radiator is arranged on the outer surface at the bottom of the box, and the upper surface of radiator covers through hole; Be tightly connected by latex between the upper surface of described radiator and the outer surface at the bottom of the box, make the inner cavity that forms sealing of compartment; Be filled with heat insulation material in the cavity of described sealing; The inner surface of described lid is provided with drier; Described semiconductor cooler is arranged in the cavity of sealing, and the hot junction of semiconductor cooler is arranged on the upper surface of radiator by heat-conducting glue; Thermistor sticks on the cold junction of semiconductor cooler, for detection of the compartment internal temperature; Also be provided with the waterproof plug-in unit on the described compartment, the lead-in wire of described semiconductor cooler and the lead-in wire of thermistor are electrically connected with the waterproof plug-in unit by welding respectively.
As the further improved technical scheme of the utility model, be bolted to connection between described lid and the box body.
As the further improved technical scheme of the utility model, be bolted to connection at the bottom of the described box and between the radiator.
Operation principle of the present utility model is as follows:
Latex time of solidifying different, according to own actual needs, selection hardening time suitable latex; Latex can solidify hardening after the regular hour, can the people be the elastic caoutchouc packing ring of building thereby form a kind of; And latex has preferably glutinous viscosity, can be two lids and box body, and bond with radiator at the bottom of the box, again play good sealing effectiveness;
2. give TEC-be semiconductor cooler-power supply, be generally the 12V dc source, semiconductor cooler will continuous cooling.Hot junction-radiating surface of TEC-be connected with radiator, thus the heat of its generation is gone out by heat sink radiates, and cold junction then can be constantly to the compartment internal refrigeration storage; Thermistor sticks on the semiconductor cooler cold junction, by peripheral circuit, detects the compartment internal temperature.
The active low temperature water-proof radiator of the utility model moves a period of time in air after, the device service behaviour is good, and opens after the box, hears " puff " one, and air-flow pours in the sound of cassette interior from the outside, and then has verified that air-tightness is fine; And use latex as sealing ring, and can set artificially its shape according to the needs of oneself, thereby save too much " die sinking " expense, use easily; Moreover,, can not occur in the conventional waterproof box as seal washer with latex, because the gasket deforms problem that the rubber washer discontinuity causes.The preparation method of the active low temperature water-proof radiator of the utility model is simple to operate, and the advantage of the active low temperature water-proof radiator of made is identical with a upper description, no longer describes in detail.In a word, the utility model manufacturing is simple, simple in structure, easy to use, and waterproof effect and fine every the air effect is convenient to practical application.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
