Abstract

Wire casing described in the utility model has a kind of new open-celled structure, three-dimensional aperture is changed to by original plane aperture i.e. on wire casing outer wall, to reach the purpose of design for increasing active convective on the basis of passive heat dissipation, to improve heat-sinking capability simultaneously and solve the problems, such as that electromagnetic exposure is influenced by bore size.Wire casing is arranged with the heat release hole of several ranks on its cell wall, is in place of difference with the prior art, and heat release hole has an outer wall that air flow spaces are formed with cell wall, outer wall not with walls parallel；In the end of outer wall, at least provided with an air inlet.The heat release hole arranged on the cell wall of wire casing is not plane aperture, but the flow-guiding channel of the solid, evagination formed by the outer wall of cell wall and heat release hole, pours into air forcibly inside wire casing.Because this not parallel flow-guiding channel has certain gradient, imported outside air will necessarily collide with wire casing Internal cable, then be reflected, the final process for flowing out wire casing and completing cold and hot exchange.

Description

Wire casing

Technical field

The utility model relates to a kind of for communicating or the Novel wire groove of power circuit, belong to mechanical with electrical design technology Field.

Background technique

As electrically with the development of mechanics of communication, the type and function of electronic equipment are more and more, electromagnetic radiation by It is gradually concerned and payes attention to.Meanwhile electronic equipment also has higher cooling requirements, the perforated area that theoretically radiates is bigger, dissipates Thermal energy power is better；And for electromagnetic radiation, opening diameter is bigger, more be easy to cause electromagnetic exposure.

The heat dissipation of available circuit wire casing be usually increase air circulation power, i.e., by increase radiating motor quantity or Frequency exchanges higher rate of heat exchange for, this not only will increase equipment cost, while also correspondingly requiring empty inside installation wire casing Between size, be not on the whole cooling measure economically and efficiently.

In view of this, special propose present patent application.

Utility model content

The present utility model application is solution the above-mentioned problems of the prior art, proposes a kind of new open-celled structure, i.e., Three-dimensional aperture is changed to by original plane aperture on wire casing outer wall, increases active convective on the basis of passive heat dissipation to reach Purpose of design, to improve heat-sinking capability simultaneously and solve the problems, such as that electromagnetic exposure is influenced by bore size.

To realize above-mentioned purpose of design, the wire casing has following technical characteristic:

It is arranged with the heat release hole of several ranks on its cell wall, is in place of difference with the prior art, heat release hole has With cell wall formed air flow spaces outer wall, outer wall not with walls parallel；

In the end of outer wall, at least provided with an air inlet.

Such as above-mentioned basic design scheme, the heat release hole arranged on the cell wall of wire casing is not plane aperture, but by slot The flow-guiding channel of solid, evagination that the outer wall of wall and heat release hole is formed, pours into air forcibly inside wire casing.Not because of this Parallel flow-guiding channel has certain gradient, and imported outside air will necessarily collide with wire casing Internal cable, Then it is reflected, the final process for flowing out wire casing and completing cold and hot exchange.

Such design structure as described in the present application can both enhance the heat-sinking capability inside wire casing, can also correspondingly reduce Bore size and the hidden danger for reducing electromagnetic exposure.

Further improvement project is, in the end of outer wall, also at least provided with an air outlet.That is, some heat release holes are only There is air inlet, and the existing air inlet of other heat release hole also has air outlet.Such similar mazy ventilating path, can increase The turbulent flow of wire casing inner air flowing is formed, local pressure is poor to be formed, and is more advantageous to the discharge of internal heat.

The measure more optimized is that the diameter dimension of the air inlet is greater than air outlet, before not increasing bore size Air import volume can be increased by putting.

For increase wire casing inner air turbulent flow, can on cell wall, in a line, adjacent heat release hole be in mirror symmetry；With/ Or, the heat release hole in same row, adjacent is axially symmetric along central axis on cell wall.

To sum up content, wire casing described in the utility model has the advantage that is with beneficial effect:

1, the design requirement of wire casing open-celled structure compatible heat dissipation and electromagnetic shielding, be highly suitable for high power cable wiring and Dynamic is the environment of free flow of air.

2, the aperture of wire casing outer surface uses " convex " shape and gradient stereochemical structure, convenient for when air circulation that outside is warm It spends lower air to import in wire casing, and effectively dissipates.

3, wire casing design cost is lower, and the processing is simple, can be suitable for the use field of a variety of industries and electrical equipment.

Specific embodiment

Embodiment 1, is with reference to the accompanying drawing described in further detail the utility model.

As shown in Figure 1, the wire casing, the heat release hole 20 of several ranks is arranged on cell wall 10.Wherein,

Heat release hole 20 has the outer wall 1 that air flow spaces are formed with cell wall 10, and outer wall 1 and cell wall 10 are in certain folder Angle.

As shown in Figures 2 and 3, in the end of outer wall 1, an air inlet 2 and air outlet 3 are respectively arranged with.Air inlet 2 it is straight Diameter size is greater than air outlet 3.

As shown in figure 4, only having an air inlet 2 in the end of outer wall 1.

As shown in figure 5, on cell wall 10, in a line, adjacent heat release hole 20 be in mirror symmetry.That is, adjacent heat radiation hole 20 air inlet 2 relatively arranges or the air outlet 3 in adjacent heat radiation hole 20 relatively arranges.

Meanwhile the heat release hole 20 in same row, adjacent is axially symmetric along central axis.

As described above, similar technical solution can be derived in conjunction with the plan content that attached drawing and description provide.But it is all Without departing from the plan content of the structure of the utility model, according to the technical essence of the utility model to any made by above description Component shape, size, the modification of connection type and mounting structure, equivalent variations and modification and each composition component locations and structure Slight adjustment, it is all that centralising device is sealed using boot seal, centralising device is carried out on the basis of existing structure The structure of tail portion side sealing, still falls within the interest field of technical solutions of the utility model.
