Drop on a resistor, or prevents flight animal from entering inside cabinet.The power of the resistive element of power consumption in resistance box is general
The heat that the resistive element of power consumption is produced is dispersed into air, it is necessary to install blower fan in resistance box than larger.In order to full
The different heat dispersion demand of foot, traditional way is by calculating, the blower fan of different air quantity being selected, by principle of conservation of energy：
The heat that energy+air that the energy that resistive element is produced=resistor main body absorbs is taken away, is that air quantity may be selected to close according to this rule
Suitable blower fan, so as to meet actual radiating effect.But the cost of blower fan increases with the increase of power of fan, and it is high-power
Blower fan consume larger electric energy.
The structure of current resistance box is as shown in figure 1, including case body 1 and the resistive element 2 being placed in case body 1, case
Blower fan 3 is provided with body 1, inventor has found, for the consideration to installing maintenance and electric property, resistive element 2 and case body 1
Channel circumference between inwall has larger distance, and resistive element 2 is located at the middle part of case body 1, because air quantity is always toward windage
Low place flows away, and result in channel circumference has larger air quantity, and the air quantity for flowing through the resistive element 2 of centre is minimum, influence
Radiating effect inside resistance box, to reach more preferable radiating effect, have selected more powerful blower fan, the air quantity of loss is got over
Greatly, the cost thereby resulted in is higher.
The content of the invention
There is above-mentioned technical problem for prior art, the present invention provides a kind of air quantity that reduces and is lost in, and improves internal heat dissipating
The resistance box for being easy to wind guide and heat dispersion of performance.
To achieve the above object, the present invention provides following technical scheme：
A kind of resistance box for being easy to wind guide and heat dispersion is provided, includes the case body of hollow formation inner chamber, the case body includes continuous
Carrying section and set section, the set section is used to place resistive element, and the inside of the carrying section, which is provided with, to be used to hold towards described
The blower fan of section blowing is put, the inwall of the set section is fixed with the air guide member protruded towards inner chamber.
Wherein, the air guide member is tabular, and the angle between the internal face of the air guide member and the case body is
120°~170°。
Wherein, the air guide member is tilted towards away from the blower fan direction.
Wherein, the air guide member has polylith, length direction arrangement of the polylith air guide member along set section.
Wherein, the cross section of the set section is polygon, and each internal face of set section is provided with polylith air guide member,
Length direction arrangement of the polylith air guide member along each internal face of set section.
Wherein, the cross section of the set section is quadrangle.
Beneficial effects of the present invention：
Compared with prior art, a kind of resistance box for being easy to wind guide and heat dispersion of the invention, leads due to being provided with case body interior
Wind part,（1）Can be air flow guide resistive element between resistive element and case inner body wall face be flowed through, in the wind of same power
Under machine effect, the loss of air quantity is reduced, the air quantity for flowing through resistive element is bigger, takes away more heats, it is to avoid case body is local
Temperature Centralized is too high, improves radiating effect；（2）The wind of resistive element is blown to from air guide member and blower fan directly blows to resistive element
Wind interlocks flowing, and turbulent flow is formed between resistive element, it is easier to take away the heat of resistive element generation.

Embodiment
Below in conjunction with specific embodiment and accompanying drawing, the present invention is described in detail.
The a kind of of the present embodiment is easy to the resistance box of wind guide and heat dispersion, as shown in Fig. 2 including the case body of hollow formation inner chamber
1, case body 1 includes continuous carrying section 11 and set section 12, and set section 12 is used to placing resistive element 2, set section 12 it is upper
There is certain gap between end opening air draft, resistive element 2, the inside of carrying section 11, which is provided with, is used for what is dried towards set section 12
Blower fan 3, the fluid that blower fan 3 is blown out is as shown in the dotted arrow 5 in Fig. 2.The cross section of set section 12 is quadrangle, set section 12
Each internal face be provided with polylith air guide member 4, length direction row of the polylith air guide member 4 along each internal face of set section 12
Cloth.The one end of air guide member 4 is fixed with the inwall of set section 12, and the other end is tilted vacantly in the lumen towards away from the direction of blower fan 3.When
So the free end of air guide member 4 can be tilted towards close to the direction of blower fan 3 in practice, can be more after so distinguished and admirable impact air guide member 4
Resistive element 2 is flowed to more and forms bigger turbulent flow effect, takes away more heats.Alternatively, it is also possible to being a portion
The free end of air guide member 4 is tilted towards close to the direction of blower fan 3, and the free end of another part air guide member 4 is tilted away from the direction of blower fan 3,
Meet the cooling requirements of different resistance boxes.In the present embodiment, according to the distance between resistive element 2 and the internal face of case body 1, push away
The angle gone out between the internal face of air guide member 4 and case body 1 can be 120 ° ~ 170 °, and the different angle of inclination of air guide member 4 is right
Radiating effect inside case body 1 is also different.Can also every piece of air guide member 4 wind surface increase dividing plate, dividing plate stand in by
Wind face is distinguished and admirable more uniformly to be guided by air guide member 4.
Compared with prior art, a kind of resistance box for being easy to wind guide and heat dispersion of the invention, due to being set inside case body 1
Air guide member 4,（1）Script can be flowed through the air flow guide resistive element 2 between resistive element 2 and the internal face of case body 1,
Under the blower fan 3 of same power is acted on, the loss of air quantity is reduced, the air quantity for flowing through resistive element 2 is bigger, takes away more heats,
Avoid the local temperature of case body 1 from concentrating too high, improve radiating effect；（2）Be oriented to through air guide member 4 be blown to the wind of resistive element 2 with
The wind that blower fan 3 directly blows to resistive element 2 interlocks flowing, turbulent flow is formed between resistive element 2, it is easier to take away resistive element
2 heats produced；（3）The outside wall surface of too high heat from case body 1, which sheds, can influence the equipment around resistance box, or injury
To staff, the air guide member 4 of the application is directly contacted with the inwall of case body 1, and the heat of case body 1 can be transferred to wind-guiding
On part 4, air quantity, which directly impacts air guide member 4, to take away the heat of the side wall of case body 1, thus air guide member 4 also function to it is heat-insulated
Effect, so as to reduce the temperature of the side wall of case body 1, reduces heat and is shed from the side of case body 1.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than to present invention guarantor
The limitation of scope is protected, although being explained with reference to preferred embodiment to the present invention, one of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent substitution, without departing from the reality of technical solution of the present invention
Matter and scope.
