Description

A kind of cooling device for cooling cavities inner surface

Technical field

The utility model be related to it is a kind of each inner surface of cavity, particularly airtight cavity is cooled down, control housing surface And the cooling orifice fitting of internal temperature, can be widely applied to the industries such as building materials, chemical industry, electrical equipment, such as waste incineration production line In incinerator material-pulling device and cement producing line high temperature equipment airtight cavity cooling.

Background technology

It is using the fin of venetian blind type, by wind such as cooling for computer CPU in the cooling means that there is now The cold wind of fan takes away heat, so as to reach the purpose of cooling down；For another example tubular heat exchanger, is shunted using tubule, is passed through Cold wind reaches cooling effect with the heat exchange of pipe surface.Although both approaches can to a certain extent play the work of cooling With, but there is also deficiency.The fin of such as venetian blind type, is only applicable to the cooling of small-sized cavity, for large-scale airtight cavity Cooling for, cost is too high；For another example tubular heat exchanger, its structure is complex, and in heat exchanging process cold wind with treat cold But medium is not directly contacted with, and cooling effectiveness is relatively low.

Utility model content

The purpose of this utility model is：In for the traditional cooling means of solution, using its cost of the fin of venetian blind type It is high；Using its complex structure of shell and tube heat-exchange method and the low defect of cooling effectiveness, can be effective the utility model proposes one kind The cooling orifice fitting of cooling cavities, particularly airtight cavity inner surface.The device can be in cavity inner surface and cavity Portion effectively cool down and lower the temperature, while having simple structure, the advantages of cost is relatively low and easy to implement.

The purpose of this utility model is realized by following technical proposals：

A kind of cooling device for cooling cavities inner surface, sets at least one cooling orifice plate, Cooling Holes in cavity Along being connected with cavity inner surface, Cooling Holes edges of boards edge offers the passage of the inner surface of some laminating cavitys to edges of boards.

Alternatively, passage is selected from one or more in semicircle orifice, 1/4 circular hole and rectangular opening.

Alternatively, the surrounding edge of cooling orifice plate is connected with cavity inner surface and separates cavity.

Alternatively, cooling orifice plate has multiple, is spaced between each cooling orifice plate.

Used as further selection, ventilation hole site is staggeredly arranged between adjacent cooling orifice plate.

Used as another further selection, vent shapes are different between adjacent cooling orifice plate.

Alternatively, cavity is airtight cavity.

The foregoing main scheme of the utility model and its each further selection scheme can be with independent assortments to form multiple schemes, For the utility model can be used and claimed scheme；And the utility model, (each non conflicting selection) selection between and Can also independent assortment and other selections between.Those skilled in the art are after the present invention program is understood according to prior art and public affairs Know that general knowledge can understand there is multiple combination, be the claimed technical scheme of the utility model, exhaustion is not done herein.

Workflow of the present utility model：Cooling orifice plate is set in cavity, and cooling orifice plate is connected with cavity inner surface, chamber The heat of body is partially transferred to cool down orifice plate, increases heat exchange area；In cooling orifice plate upper vent hole position of opening laminating cavity Surface, guiding cold air is close to cavity inner surface flowing, contacts and carry out heat exchange rapidly with cavity inner surface, improves cooling effect Rate；The multiple cooling orifice plates that passage hole shapes are different, position is staggered of setting, make cooling air in chamber in airtight cavity Internal flow region is more extensive, and heat exchange is more abundant；Passage perforate can be according to the shape of airtight cavity, volume size, cold But air velocity etc. needs to may be selected to take various forms.

The beneficial effects of the utility model：The cavity of different volume sizes, particularly airtight cavity inner surface can be entered Row cooling, while controlling inside cavity temperature.Its main embodiment is to design to be connected as with table in cavity in airtight cavity The cooling orifice plate of one, simple structure, cost is relatively low and easy to implement.

Specific embodiment

The utility model is further described with reference to specific embodiments and the drawings.

With reference to shown in Fig. 1, an airtight cavity 2 is surrounded by top board (not shown), base plate and four cycle side plates, cooling is empty Gas enters from cooling air intake 4；Two cooling orifice plates 3 being connected with top board, base plate and side plate are set in airtight cavity 2, The heat of cavity is partially transferred to cool down orifice plate 3, increases heat exchange area；The cooling side of orifice plate 3 four and corner offer laminating The passage 1 of the inner surface of airtight cavity 2, guiding cold air is close to the flowing of the inner surface of airtight cavity 2, with the inner surface of airtight cavity 2 Contact and carry out heat exchange rapidly, improve cooling effectiveness；Two adjacent cooling orifice plate 3 hole shapes are different, position staggered row Cloth, makes that flow region of the cooling air in airtight cavity 2 is more extensive, and heat exchange is more abundant；In cooling air and airtight cavity 2 It is changed into hot-air after table and the cooling surface sufficient heat exchange of orifice plate 3 to be discharged by hot air outlet 5, whole process continuous service makes Airtight cavity 2 is winding is effectively cooled.

Wherein cooling orifice plate can have various ways according to ventilation well format and the difference of arrangement：

With reference to shown in Fig. 2, a kind of open-cellular form of the passage 1 for cooling down orifice fitting, in the logical of four side open semicircle shape holes Stomata 1；Open the passage 1 of 1/4 circular port in corner location, make cold air by when with the upper lower inner surface of airtight cavity 2 Laminating, increases heat transfer rate and efficiency.

In figure 3, the open-cellular form of the passage 1 of another cooling orifice fitting, in the ventilation in the equal open semicircle hole in four sides Hole 1, and position of opening and Fig. 2 position of opening interlaced arrangement.

In fig. 4, the open-cellular form of the passage 1 of another cooling orifice fitting, rectangular opening is opened in four sides with corner location Passage 1, operation principle is identical with Fig. 2, Fig. 3.

Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
