The specific embodiment
With reference to figure 2, be the pre-burning stove backboard side schematic diagram of first embodiment, will carry on the back cover plate and remove to dispose in the clear demonstration stove.In the present embodiment, be to continue to use existing furnace binding to carry out improvement design.Pre-burning stove shown in the figure includes a body of heater 10, body of heater 10 has a relative slot side 101 and a backboard side 102, wherein in slot side 101, body of heater 10, define an element under test accommodation space 103, in backboard side 102, body of heater 10, define a circuit board accommodation space 11 and a ventilated cavity 12 as shown in Figure 1.Ventilated cavity 12 directly is communicated with circuit board accommodation space 11.Passing away 20 vertical type shelfs of one body kenel are located in the ventilated cavity 12, and its end extends to body of heater 10 outer surfaces, and especially, are provided with a plurality of connected holes 21 in passing away 20 peripheries.
In addition, also show two carriers 13,14 among the figure and be arranged in circuit board accommodation space 11, each carrier 13,14 all carries a plurality of circuit boards 15, and a plurality of circuit board 15 is arranged the many rows of formation channel plate arrays along the body of heater short transverse.The avris of each carrier 13,14 is assembled with radiator fan group 16,17, and each radiator fan group comprises a plurality of radiator fans, corresponding to aforementioned many row's channel plate arrays.Wherein, the radiator fan group 16 of corresponding carrier 14 also is positioned at passing away 20 sides simultaneously.
In addition, on passing away 20, also dispose a motor fan group 22.Present embodiment is the end that motor fan group 22 is configured in passing away 20.Motor fan group 22 is meant the combination that is driven a fan 222 by a motor 221, and fan 222 is coaxial to be arranged on the axle of motor 221.
When real-world operation, cooling blast is drawn by the single motor fan group 18 that is arranged on circuit board accommodation space 11 tops and enters circuit board accommodation space 11. Radiator fan group 16,17 then forces cooling blast to flow through a plurality of circuit boards 15.During this period, owing to only link up between passing away 20 and the circuit board accommodation space 11 by connected holes 21, and the motor fan group 22 that more powerful exhausting ability is arranged in passing away 20 is in the running exhausting, passing away 20 forms a kind of relative vacuum environment, making cold gas fail to be convened for lack of a quorum more is inclined to toward each connected holes 21 diffluence, make cooling blast more average, even this means that also the circuit board 15 that is positioned at accommodation space 11 Lower Halves also designs easier the flowing through of cooling blast that receive compared to having now for the flow distribution of diverse location circuit board 15.
Show that via the actual experiment result pre-burning stove design of the present utility model is compared to the existing body of heater Lower Half thermal phenomena that improved, the temperature difference reaches 25 degree C.
With reference to figure 3A and 3B, be the body kenel passing away sectional elevation of second embodiment.The present embodiment and first example are roughly the same on structure, but only its difference is in connected holes 31 selecting types of passing away 30 and opens and closes, and for example control being communicated with of passing away and circuit board accommodation space in the mode that gate 32 is set.Open and close design by such hole selecting type, when the connected holes 31 of the first half is closed, can receive the effect of strengthening the heat radiation of body of heater Lower Half.Therefore when the body formula passing away 30 that this is routine is assembled in different system of bf body, can carry out accommodation, to obtain best radiating effect.
With reference to figure 4, be the pre-burning stove backboard side schematic diagram of the 3rd embodiment, will carry on the back cover plate and remove to dispose in the clear demonstration stove.The pre-burning stove structure of present embodiment emphasizes that mainly the formation of passing away 45 is by being communicated with interface than large tracts of land and replacing with a barricade 41 available circuit plate accommodation space and ventilated cavity, and on barricade 41, offer a plurality of connected holes 42, making circuit board accommodation space 43 and being communicated with of ventilated cavity 44 (also becoming aforesaid passing away 45 this moment) is to reach by a plurality of connected holes 42 equally.Certainly, barricade 41 can be to be that basic additional set installs with existing pre-burning furnace structure, also can be directly to make with body of heater 40, becomes the part of this body of heater 40.Present embodiment has the effect of improving the long-pending heat of body of heater backboard side Lower Half too.
Fig. 5 is the pre-burning stove backboard side schematic diagram of the 4th embodiment.Present embodiment and the 3rd example are roughly the same on structure, but only its difference is in and is designed to selecting type in the connected holes 51 of passing away 50 and opens and closes, and for example uses gate 52 means that are similar to Fig. 3.
From the above, the utility model can be obtained better radiating effect with the motor fan group of identical or smaller amounts compared to existing design, for example Fig. 2 example is used a ventilating fan less compared to the existing design of Fig. 1, and but significantly radiating effect has improved the long-pending heat problem of body of heater Lower Half simultaneously.Owing to use the fan assembly of smaller amounts, not only save acquisition cost, maintenance cost, naturally also descended in the supply of electric power demand side of fan assembly, can reach the energy-conserving and environment-protective purpose.
The foregoing description is only given an example for convenience of description, and the interest field that the utility model is advocated should be as the criterion so that claim is described certainly, but not only limits to the foregoing description.
