Flow direction in pipeline body 10 is more chaotic, it is easier to cause vortex, it is easier to turbulent flow is formed, to keep heat exchange performance more preferable.
Optionally, the quantity of upper pit part 1 is identical as the quantity of lower pit part 2.
As shown in figure 4, on above-described embodiment basis, further, along the length direction and pipeline of pipeline body 10
The width direction of ontology, the pit for the upper wall 11 being disposed adjacent and the pit of lower wall 12 are the first pit or second dimple.
So, the pit of upper wall and the pit of lower wall are capable of forming multirow (length direction along pipeline body is row)
Pit, pit include the first pit and second dimple, and corresponding multirow pit is divided into the first pit row 3 and second dimple row 4, more
A first pit row 3 and multiple second dimple rows alternate setting, and the first pit row includes the first pit 21 of upper pit part 1
With the first pit 21 in lower pit part 2, second dimple row includes in second dimple 22 and lower pit part 2 in upper pit part 1
Second dimple 22.The first pit in upper pit part in first pit row with it is adjacent thereto recessed in second dimple row
The second dimple in hole portion intersects setting, generally t-shaped setting；Alternatively, the first pit in lower pit part in the first pit row
Intersect setting, generally t-shaped setting with the second dimple of the upper pit part adjacent thereto in second dimple row.This pit knot
Structure is more advantageous to form turbulent flow, being capable of formation turbulent flow earlier.
It should be noted that radiation pipe of heat exchanger of the embodiment one into embodiment three may include multiple medium circulation tubes
Road, multiple flow of media pipelines are set gradually along the conveying direction perpendicular to medium.It can independently be set with multiple flow of media pipelines
It sets, is then connected with each other, multiple next doors can also be set to be divided into multiple pipes in heat dissipation tube cavity with whole installation heat-dissipating pipe
Road.
Example IV:
The embodiment of the present invention four provides a kind of heat exchanger, the heat exchange heat-dissipating pipe provided including embodiment one to embodiment three.
Further include inlet tank and water tank, is connected to respectively with the both ends of heat-dissipating pipe into case and water tank, heat exchange medium is introduced into
Water tank is then dispensed for multiple pipeline bodies 10, after flow of media pipeline, is discharged by water tank.
Medium inside heat exchanger provided in this embodiment can form turbulent flow, and can reduce hot side resistance, so as to protect
Hinder preferable heat exchange performance, avoids hot side resistance excessively high and influence system stability.To heat exchanger provided in this embodiment
Heat exchange property is good, and system stability is good.
As shown in Figure 10, heat-dissipating pipe in the related technology, pit are in smooth vertical and horizontal setting.It is dissipated to using shown in Fig. 10
The heat exchanger of heat pipe is simulated to obtain analog result table as shown in figure 11, while at the same conditions to using such as Fig. 4
The heat exchanger provided by the invention of shown heat-dissipating pipe is simulated to obtain analog result table as shown in figure 12.It needs to illustrate
It is that operating condition refers to that the flow of medium, Figure 11 and Figure 12 are the simulations carried out in different rate-of flows.
By Figure 11 and Figure 12 it is found that under identical rate-of flow, the water collateral resistance of heat exchanger provided by the invention is less than
The hot side resistance of heat exchanger in the related technology, total heat exchange amount of heat exchanger provided by the invention are greater than heat exchange in the related technology
Total heat exchange amount of device.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
In addition, it will be appreciated by those of skill in the art that although above-mentioned some embodiments include institute in other embodiments
