Embodiment
For make above-mentioned purpose of the present invention, feature and advantage can be more obviously understandable, below in conjunction with accompanying drawing and embodiment the present invention done further detailed explanation.
With reference to Fig. 1, show the structure chart of the heat dissipation equipment of a kind of outdoor display of the present invention, comprising: heat exchange rack 11 and intersection fin 12;
Said heat exchange rack 11 comprises front console 111, side casing, back side casing 112, top cover 113 and bottom 114, built-in display 13 and intersection fin 12; Wherein, Display 13 surrounds rising air channel 115 with front console 111, side casing; Display 13 surrounds decline air channel 116 with back side casing 112, side casing, and the top in rising air channel 115 and decline air channel 116 is communicated with, and said bottom 114 is provided with air inlet 117 and air outlet 118; Air inlet 117 is communicated with rising air channel 115, and air outlet 118 is communicated with decline air channel 116;
Said intersection fin 12 places on the back side casing 112 of heat exchange rack, comprises two-layer at least heat dissipating layer, and each heat dissipating layer is made up of a plurality of bonding jumpers 121 that connect side by side along level or vertical direction; Wherein, adjacent heat dissipating layer, the orientation of bonding jumper is orthogonal.
Below, the temperature control system of the described outdoor display of the embodiment of the invention is specified:
Said heat exchange rack is used to place display on the one hand, is mainly used on the other hand the temperature around the display is regulated, and prevents that temperature is too high.Common, in order to show the displaying contents of display more clearly at the front end of heat exchange rack, the front console of said heat exchange rack is a face glass.In practical application, the side casing of said heat exchange rack, back side casing, top cover and bottom can be metal shell, and for example, said metal material can be iron, aluminium etc.
Air gets into the rising air channel in the heat exchange rack through the air inlet on the bottom, in the rising air channel, accomplishes heat exchange, takes away the heat of display front.Because the connection of the top in rising air channel and decline air channel, get into the decline air channel again after then arriving the top in rising air channel.Air is accomplished heat exchange in the decline air channel, take away the heat at the display back side.
Need to prove, can below the top cover of heat exchange rack, wind deflector be set, make the one of which end place the top of front console, the other end places on the casing of the back side, is used for the wind in rising air channel is imported in the decline air channel.Said wind deflector can be set to arcuate structure; Has downward concave surface; Because this wind deflector has smooth arc-shaped curved surface, then get into the wind in rising air channel, behind the top that arrives the rising air channel by wind inlet channel; To get into the decline air channel along the arc-shaped curved surface of wind deflector, good guiding the flow direction of wind.
Common, if the heat that display generated when working can not in time distribute, then can make the inside of heat accumulation at the heat exchange rack, cause the rack enclosure temperature to raise, particularly the heat of display back circuit board generation makes that back side casing temperature is higher.The back side casing of embodiment of the invention heat exchange rack is provided with the intersection fin, and said intersection fin can absorb the heat on the casing of the back side, and most of heat is collected on the intersection fin.When air gets into the decline air channel, take away the heat on the fin by air, go out from air outlet, played good thermolysis.
Intersection fin of the present invention has unique design, and it comprises two-layer at least heat dissipating layer, and each heat dissipating layer is made up of a plurality of bonding jumpers that connect side by side along level or vertical direction; Wherein, adjacent heat dissipating layer, the orientation of bonding jumper is orthogonal.
In order to carry out heat conduction fully between the heat dissipating layer, carry out bonding through the heat conduction adhesive tape between the adjacent heat dissipating layer.The design of multilayer has increased the surface area that fin and air are in contact with one another, and is more conducive to heat radiation.In addition because each layer heat dissipating layer bonding jumper direction side by side is vertical each other, then can make air from top to bottom simultaneously, mobile in fin by left-to-right (or by the right side to a left side), twocouese carries out exchange heat, can more dispel the heat more fully soon.
In a preferred embodiment of the invention, said bonding jumper is aluminum strip or copper bar.
Metallic aluminium has good heat-conducting, can absorb the heat on the rack enclosure that is in contact with it fast, and in addition, the price of aluminium is lower, has also possessed the good metal cutting characteristic, therefore, is very suitable for making fin.In general, the heat conductivility of a simple metal will be better than its thermal conductivity of alloy.But can also adopt aluminium alloy to make the intersection fin usually, to obtain than the better metal processing characteristics of fine aluminium.
The heat conductivility of metallic copper almost is equivalent to the twice of aluminium, also can be used to make fin.But the heat dissipation of fin is influenced by the thermal conductivity the subject of knowledge and the object of knowledge of material not only, also will consider heat dispersion, and the radiating effect of copper radiating rib can not reach the twice of aluminium radiator fin.Preferably, said intersection fin can adopt the metallic copper manufacturing with one deck or two-layer heat dissipating layer that back side casing is pressed close to mutually, to accelerate the absorption of heat; And other heat dissipating layer can adopt metallic aluminium manufacturing, is beneficial to distributing fast of heat.
In a preferred embodiment of the invention, being shaped as of the cross section of said bonding jumper:
shape, " " shape, perhaps
shape.The shape in above-mentioned cross section not only can increase the surface area that fin and air are in contact with one another, and makes air pass through from bar surface or internal pipeline more swimmingly in addition, utilizes the flowability of air.
As shown in Figure 2, have the structural representation of the intersection fin embodiment of two heat dissipating layers for the present invention is a kind of; Wherein, Fig. 2 (a) is the stereogram with intersection fin of two heat dissipating layers; Fig. 2 (b) is the cutaway view of the A-A line of intersection fin with two heat dissipating layers.
