Server 13, cloud server 13 is by above-mentioned data transfer to client 14.Client can obtain the letter of system operation in time
Breath.
Preferably, heat exchanger is convector.Certain sewage, which can be directly entered in convector, to heat,
As shown in Figure 1.Certainly, after the recirculated water in radiator can also be exchanged heat by heat exchanger and sewerage, it is recycled to heating
Radiator heats.
The radiator includes upper header and lower collector pipe, and heat-dissipating pipe is connected between the upper header and lower collector pipe, such as Fig. 2,3
Shown, the heat-dissipating pipe includes base tube 15 and the cooling fin 17-19 positioned at base tube periphery, as shown in Figure 2,3, the base tube
Cross section is isosceles triangle, and the cooling fin includes the first cooling fin 17 and the second cooling fin 18,19, first cooling fin
17 be outwardly extending from isosceles triangle apex angle, and second cooling fin 18,19 includes two waist institutes from isosceles triangle
The multiple cooling fins 18 extended outwardly and from the outwardly extending multiple cooling fins 19 of the first cooling fin, to same direction
The second cooling fin 18,19 extended is parallel to each other, for example, as shown, from the second waist of isosceles triangle 21（The waist on the left side）To
Second cooling fin 18,19 of outer extension is parallel to each other, from the first waist of isosceles triangle 20（That is the waist on the right）Outwardly extending
Two cooling fins 18,19 are parallel to each other, and the end that first cooling fin 17, the second cooling fin 18,19 extend forms the second isosceles
Triangle, as shown in Fig. 2, the length of the waist of the second isosceles triangle is S；15 inside setting first fluid channel of the base tube
16, first cooling fin, 17 inside setting second fluid channel 24, the first fluid channel 17 and second fluid channel connect
Logical 24.For example, as described in Figure 2, being connected in isosceles triangle corner position.
General heat-dissipating pipe is all surrounding or both sides setting cooling fin, but is found in engineering, one contacted with wall
Heat convection effect is bad under normal circumstances for the cooling fin of side, because air flows relatively poor, therefore this hair in wall side
It is bright to set isosceles triangle bottom edge 22 to plane, therefore when installation cooling fin, it can be directly close with wall by plane
Contact, compared with other radiators, can greatly save installation space, avoid the waste in space, while take special dissipate
Backing form, guarantee meet best heat dissipation effect.

Relative to the face mirror symmetry where the line at the midpoint where the vertex and bottom edge of isosceles triangle.
Preferably, the second cooling fin extends perpendicular to two waists of the second isosceles triangle.
In the case that the length on the side of isosceles triangle is certain, the first cooling fin 17 and the second cooling fin 18,19 are longer, then
Theoretically heat transfer effect is better, finds during the test, when the first cooling fin and the second cooling fin reach certain length
It waits, then heat transfer effect just increases very unobvious, is primarily due to increase with the first cooling fin and the second fin length, dissipate
The temperature of backing end is also lower and lower, as temperature reduces to a certain extent, then can lead to heat transfer effect unobvious, opposite to go back
It increases the cost of material and considerably increases the space of radiator occupied, meanwhile, in heat transfer process, if the second heat dissipation
Spacing between piece is too small, also be easy to cause the deterioration of heat transfer effect, because with the increase of heat dissipation length of tube, air rose
Boundary layer thickens in journey, and boundary layer mutually coincides between causing abutting fins, deteriorates heat transfer, and heat dissipation length of tube is too low or the
Spacing between two cooling fins causes heat exchange area to reduce very much greatly, affects the transmission of heat, therefore in the second adjacent heat dissipation
Between the distance of piece, the length of side of isosceles triangle, the first cooling fin and the length and heat sink length of the second cooling fin
Meet the size relationship of an optimization.
Therefore, the present invention best is dissipated by what thousands of secondary test datas of the radiator of multiple and different sizes summed up
The dimensionally-optimised relationship of hot device.
The distance of the second adjacent cooling fin is L1, and the bottom edge length of the isosceles triangle is W, described second

Preferably, the providing holes 23 on the first and/or second cooling fin, for destroying laminar sublayer.Main cause is
Two cooling fins are mainly exchanged heat by the convection current of air, and air carries out the stream of free convection from the bottom of the second cooling fin upwards
Dynamic, during air flows upwards, the thickness in boundary layer constantly becomes larger, in addition finally result in adjacent second cooling fin it
Between boundary layer overlapped, such situation can cause heat exchange deterioration.Therefore boundary layer can be destroyed by providing holes 9,
To augmentation of heat transfer.
Preferably, the shape in hole 23 is semicircle or round.
Preferably, hole 23 penetrates through entire cooling fin.
Preferably as one, along the direction of the flowing of air, i.e., from the bottom of radiator to the top of radiator, hole 23

Times.
Preferably as one, on same second cooling fin, from cooling fin root（I.e. with the interconnecting piece of base tube 15）To heat dissipation
Between piece top, the area in each hole 239 constantly becomes smaller.Main cause is the temperature of cooling fin from cooling fin root to cooling fin top
Degree is continuous to be declined, therefore the thickness in boundary layer constantly reduces, and the area in the hole 23 by the way that variation is arranged may be implemented to destroy
The thickness of the different location in boundary layer, to save material.
Preferably, the absolute temperature is proportional to example relationship in the variation and cooling fin of the area in hole 23.
Preferably as one, on same second cooling fin, from cooling fin root（I.e. with the interconnecting piece of base tube 1）To cooling fin
Between top, the density in hole 23 constantly reduces.Main cause is from cooling fin root to cooling fin top, and the temperature of cooling fin is continuous
Decline, therefore the thickness in boundary layer constantly reduces, the density in the hole 23 by the way that variation is arranged may be implemented to destroy boundary layer
The thickness of different location, to save material.
Preferably, the absolute temperature is proportional to example relationship in the variation and cooling fin of the density in hole 23.
Preferably, for the width b2 between the second cooling fin it is changed according to certain rule, specific rule is
From the base angle of isosceles triangle to apex angle, the width of the second cooling fin 18 extended from two waists of isosceles triangle is increasingly
Greatly, from the apex angle of isosceles triangle to the end of the first cooling fin 17, the second cooling fin 19 extended from the first cooling fin 18 is wide
It spends smaller and smaller.Main cause is the second cooling fin being arranged in waist, and heat dissipation capacity is gradually increased from base angle to apex angle, therefore is needed
Increase the area of heat dissipation, therefore increases the heat dissipation area of cooling fin by increasing the width of cooling fin.Similarly, along first
Cooling fin 18, from bottom to end, the quantity of heat dissipation is fewer and fewer, therefore the corresponding area for reducing cooling fin.By such
Setting, can greatly improve radiating efficiency, while greatly saving material.
Preferably, from the base angle of isosceles triangle to apex angle, from the second heat dissipation of two waists of isosceles triangle extension
The increased amplitude of 18 width of piece is increasing, from the apex angle of isosceles triangle to the end of the first cooling fin 17, from the first heat dissipation
The amplitude for the 19 width reduction of the second cooling fin that piece 17 extends is smaller and smaller.It is found through experiments that, by above-mentioned setting, with increase
Or reduce that amplitude is identical compares, about 16% heat dissipation effect can be improved.Therefore there is good heat dissipation effect.
