Description
Technical field
It the utility model is related to the probing shell cooling device of a kind of shell cooling device, more particularly to flame detector.
Background technology
Flame detector is generally used to detect the extinguishing of stove fire, if stove fire goes out, can produce carbon monoxide toxic gas,
Serious consequence is caused, therefore the importance for detecting the state of stove fire is extremely important, and the temperature of stove fire is higher, flame detector
In detection, if without cooling, the rise sensitivity with photomultiplier probe self-temperature can decline rapidly, also very
It is easily damaged, therefore the cooling of flame detector is extremely important.
Before the present utility model, at present the cooling means of flame detector be carried out with coldplate or water collar it is cold
But flame detector is protected, while needs to coordinate coolant to be used together, shared space is bigger, that makes is cold
But device is just larger and heavy, in-convenience in use, cost is also high.
Utility model content
The purpose of this utility model, which is that, overcomes drawbacks described above, develops the probing shell cooling device of flame detector.
The technical solution of the utility model is：
The probing shell cooling device of flame detector, pipe is interior to be set and fixes convex lens, and photomultiplier is also provided with
In pipe, it is mainly characterized by the huyashi-chuuka (cold chinese-style noodles) that semiconductor chilling plate is connected on square tube side, the semiconductor refrigerating
One layer of heat-conducting silicone grease has been smeared on the huyashi-chuuka (cold chinese-style noodles) of piece, fin, the semiconductor refrigerating are connected on the hot face of semiconductor chilling plate
One layer of heat-conducting silicone grease, the another side connection fan of fin have been smeared on the hot face of piece.
The huyashi-chuuka (cold chinese-style noodles) of semiconductor chilling plate is pasted on the square tube side.
Paste the one side of fin in the hot face of the semiconductor chilling plate.
The pipe is divided into big pipe, small pipe, and big pipe lower end is threadedly coupled small pipe, and convex lens set and are fixed on
In big pipe, photomultiplier sets and is fixed in small pipe.
The advantages of the utility model and effect are to use using the method for wind-cooling heat dissipating, the radiating in the hot face of cooling piece
Wind-cooling heat dissipating, i.e., using the copper or aluminium heat sink of ribbed, and aerofoil fan or centrifugal fan are equipped with by the heat band in hot face
Walk, and do not need any refrigerant, can continuously work, without pollution sources, gyroscopic action will not be produced, vibrations during work, make an uproar
Sound is small, long lifespan, and installation is easy, the temperature range on cooling piece two sides, can be realized from 40 DEG C to 65 DEG C.Using semiconductor system
Cold cools down to shell, it is not necessary to coolant, a thin layer of heat-conducting silicone grease first is coated toward the hot face of semiconductor chilling plate,
Then press on a heat sink, then one layer of heat-conducting silicone grease is applied toward huyashi-chuuka (cold chinese-style noodles), the huyashi-chuuka (cold chinese-style noodles) for smearing one layer of heat-conducting silicone grease is attached to device
On shell, on a heat sink, fin and fan are bolted to dress by four mode connects for screw, fan with two for hot face fitting
Put, semiconductor chilling plate is just fastened by the bolt of fan and canning to fix.Flame detector when detecting stove fire,
Furnace temperature is higher, and the temperature of whole flame detector device can gradually rise, especially the rise of photomultiplier probe temperature, its spirit
Sensitivity can rapidly decline and be easy to damage, and just can not normally detect the extinguishing of stove fire, be likely to result in instantly
The dire consequences that carbon monoxide toxic gas overflows.Therefore, cooling device of the present utility model detects stove fire in flame detector
When, flame detector especially photomultiplier refrigeration cool-down is given, avoids flame detector from being too high to normal work because of temperature
Make the dire consequences brought.

Embodiment
Technical thought of the present utility model is：
The utility model come cooling protection flame detector, is using cooling piece using the refrigeration of semiconductor chilling plate
During, it is most important that the heat in hot face is timely scattered to outside, so just can guarantee that good refrigeration.Dissipate
Heat is exactly heat transfer, and the transfer mode of heat has three kinds：Conduction, radiation and convection current.Conduction be by the relatively low particle of energy and
The higher particle of energy direct contact-impact transmits the mode of energy；Radiation is exactly that heat energy directs out boundary from thermal source and exhaled
Go, the process is relevant with heat source surface color, material and temperature；Convection current refers to hotter part or colder part in gas or liquid
By circulating equalizing temperature.
The utility model is specifically described below.
As shown in Figure 1：
Convex lens 1 are set in big pipe 2, and in the upper and lower placement metal washer 13 of convex lens 1, convex lens 1 are at this two
Between metal washer, convex lens 1 are fixed by the threaded connection of big pipe 2 and small pipe 3；Photomultiplier 4 is in small pipe 3
Interior, the small bottom of pipe 3 connects square tube 5, and the connecting line 12 for connecting photomultiplier 4 is drawn from the lower end of square tube 5, in the side of square tube 5
The huyashi-chuuka (cold chinese-style noodles) 7 of (stickup) semiconductor chilling plate is connected on face, the huyashi-chuuka (cold chinese-style noodles) 7 has smeared one layer of heat-conducting silicone grease, the heat of semiconductor chilling plate
Face 8 connects the wherein one side of fin 9, and one layer of heat-conducting silicone grease, the another side of fin 9 connection fan 10, wind have been smeared in the hot face 8
Fan 10 is with two square tubes for being bolted to device 5, and small pipe 3 and square tube 5 are connected by special fluid sealant strength, fan
Draw plug 11 on 10, semiconductor chilling plate 6 draw wiring 14.
Application process brief description of the present utility model：
The phenomenon that whole device temperature gradually rises inevitably occurs when detecting stove fire for flame detector, this
When the utility model will play sizable effect.All parts are electrified, the cold i.e. huyashi-chuuka (cold chinese-style noodles) of the one side of semiconductor chilling plate 6
7, simultaneously heat is hot face 8, is freezed using the huyashi-chuuka (cold chinese-style noodles) 7 of semiconductor chilling plate 6, and to reach the effect that huyashi-chuuka (cold chinese-style noodles) 7 has refrigeration, just
Ensureing the radiating effect in hot face 8 will get well.Powerful wind-force is ceaselessly produced using fan 10 to bring extraneous cold wind, by dissipating
Backing 9 increases the contact area with hot face 8, the heat on hot face 8 is taken away, so as to reach the hot face 8 to semiconductor chilling plate 6
Radiating purpose, therefore the huyashi-chuuka (cold chinese-style noodles) 7 of semiconductor chilling plate 6 will ceaselessly play refrigeration, the huyashi-chuuka (cold chinese-style noodles) of semiconductor chilling plate 6
7th, the hot maximum of face 8 can realize 65 DEG C of the temperature difference, and its good refrigeration can effectively protect the use of flame detector.
Therefore, cooling device of the present utility model gives flame detector especially light when flame detector detects stove fire
Electric multiplier tube refrigeration cool-down, flame detector is avoided because temperature is too high to normal work, avoid flame detector because being burnt
The extinguishing of stove fire can not badly be detected and cause toxic gas carbon monoxide dire consequences caused by instantly overflowing.
