Detailed Description
In order to further describe the technical means and effects adopted by the utility model for achieving the preset aim, the following detailed description is given below of the specific implementation, structure, characteristics and effects according to the utility model with reference to the attached drawings and the preferred embodiment.
Referring to fig. 1-3, a corrugated cooling water pipe comprises a pipe body 1 and a hydrophobic layer 2, wherein the hydrophobic layer 2 is positioned on the inner wall of the pipe body 1 and is used for reducing resistance to water flowing in the pipe body 1 and adhered to the pipe wall.
The water flow flowing at the pipe wall is the outer water flow, and the water flow flowing at the pipe core is the inner water flow. The outer water flow is smaller in blocking force, so that the difference between the flow velocity of the outer water flow and the flow velocity of the inner water flow is smaller, turbulence fluctuation from the outer layer to the inner layer is reduced, heat transfer efficiency from the outer layer to the inner layer is reduced due to turbulence reduction, and the inner water flow can be kept in a low-temperature state for a longer time. Along with the increase of the flowing distance of the water flow, the inner water flow and the outer water flow continuously exchange heat, so that the temperature of the outer water flow is always kept in a state capable of continuously absorbing the heat of the heating source, and further the effects of reducing the local absorption and heat dissipation efficiency and improving the long-distance absorption and heat dissipation uniformity are achieved.
Compared with the prior art, the difference of the embodiment is that the pipe wall of the prior art is rough, the outer water flow is severely blocked, when the inner water flow flows at a normal speed, the difference of the flow velocity of the inner water flow and the outer water flow is extremely large, a large number of turbulent eddies are generated, the outer water flow is quickly involved in the flow area of the inner water flow, the quick heat exchange of the inner water flow and the outer water flow is realized, the internal water flow and the external water flow are absorbed in a short distance, the heat dissipation efficiency is higher, but the temperature of the cooling liquid rises rapidly, in the long-distance heat dissipation structure, the cooling liquid at the initial stage absorbs extremely much heat, when the cooling liquid at the high temperature flows to the middle and rear sections of the long-distance heat dissipation structure, the temperature difference of the cooling liquid and the heat generation source is reduced, the heat absorption and heat dissipation effects are greatly reduced, so that the long-distance heat dissipation structure has extremely good heat dissipation effect at the initial end, and the heat distribution of the heat generation source is uneven. When the heat dissipation device is applied to the vehicle battery with larger heating area, the local temperature of the battery is too high, so that the battery can be seriously deformed, and even potential safety hazards such as leakage and explosion exist. In the embodiment, considering the condition of heat dissipation uniformity, the heat absorption efficiency of the long-distance cooling structure in a section range is reduced intentionally, so that the temperature of the cooling liquid can be slowly increased in a longer distance, and further, the obvious temperature difference between the cooling liquid and a heat source is kept in the whole area of the long-distance heat dissipation structure, the heat absorption effect close to the initial section can be exerted in the middle and rear sections, and the heat dissipation of the battery is more uniform.
And if the flow rate is increased in the same way, in the prior art, if the flow rate of the cooling liquid in the long-distance cooling structure is adjusted by combining the mode of adjusting and controlling the output power of the water pump, the flow rate of the inner water flow is only accelerated, and meanwhile, the vortex flow rate of the turbulent flow from the outer layer to the inner layer is also accelerated, so that the temperature interaction of the inner layer and the outer layer is further increased, and the temperature of the cooling liquid is also rapidly increased. The low-temperature keeping distance of the cooling liquid can be prolonged only by a small amount through the effect of integrally accelerating the flow velocity. And, this approach may result in a further decrease in the initial stage temperature of the long-distance cooling structure, a further increase in the temperature difference at different portions of the battery, and a further increase in the risk of deformation of the battery. Therefore, changing the flow rate of the cooling liquid by controlling the water pump cannot be equivalent to the flow rate effect of increasing the outer water flow through the water-repellent layer 2 in the present embodiment.
When the water pressure in the pipe wall increases, the outer layer cooling liquid absorbs heat, the temperature at the pipe wall is increased, the temperature at the pipe core is kept unchanged, the difference between the outer layer water flow and the inner layer water flow is smaller, the heat absorbed by the outer layer cooling liquid of the pipe wall is slowly transferred to the cooling liquid at the pipe core, the outer layer heat is dispersed, the temperature at the pipe wall is reduced, the pipe wall always maintains a larger temperature difference with the battery pack, and the heat generated by the battery pack can be continuously absorbed, so that the cooling pipe is suitable for cooling for a longer distance, the heat generated by the battery can be uniformly absorbed, the service life of the battery is prolonged, and the safety is high.
When the flow speed of the boosting water flow is increased by using the pump, the whole flow speed of the water flow in the pipeline can be increased, but the turbulence generated by the rough pipeline wall cannot be solved, the speed difference between the outer water flow and the inner water flow cannot be solved, the heat absorption capacity in a short distance is improved, the material of the hydrophobic layer 2 is polytetrafluoroethylene, the material has the advantages of corrosion resistance, aging resistance, small water absorption and excellent self-lubricating performance, the rough pipeline wall is reduced by utilizing the material characteristic of the hydrophobic layer 2, the friction resistance between the cooling liquid and the pipeline wall is reduced, the flow speed difference between the outer water flow and the inner water flow is reduced, the vortex turbulence phenomenon in the pipeline is reduced, and the heat absorption capacity of the cooling liquid is improved.
In order to further increase the contact area between the tube body 1 and the battery pack and improve the cooling effect, in an embodiment, the tube body 1 is in a sine wave structure, the wave of the sine wave structure facing the outside of the tube is a wave crest, the wave facing the inside of the tube is a wave trough, the sine wave structure increases the surface area of the tube body 1, the contact area between the tube body 1 and the battery pack is also increased, and the cooling effect is correspondingly improved.
In order to ensure the contact area with the battery pack, the turning radius of the corrugated pipe should also be noted, in an embodiment, the interval between two adjacent wave crests of the pipe body 1 is 3-5mm, when the interval is smaller than 3mm, the contact area between the pipe body 1 and the battery pack is too large, the absorbed heat is more, the temperature of the pipe body 1 is also increased instantaneously along with the moment, the cooling effect of the tail end is poor finally due to the continuous flow of the cooling liquid, when the interval is larger than 5mm, the contact area with the battery pack is small, the absorbed heat is too small, the heat generated by the battery pack cannot be absorbed timely, and the cooling effect is poor. The turning radius of the corrugation is particularly important for the space utilization rate of the corrugated pipe, and meanwhile, when the wave crest interval is smaller than 3mm, the interval between adjacent wave crests is too small, the turning radius of the pipe body 1 is small, the pipe body 1 cannot be installed in a narrow battery pack, when the wave crest interval is larger than 5mm, the turning radius of the pipe body 1 is moderate in the range of 3-5mm, the arrangement space is saved during turning installation, the contact area between the pipe body and the battery pack is moderate in the range, the absorbed heat is stable, and the cooling effect on the battery pack is good.
In the case of the tube body 1 having a flexible characteristic and a corrugated structure, attention is paid to its structural stability, and particularly, loosening at the connection with the inlet and outlet liquid may also cause leakage of the cooling liquid, in an embodiment, as shown in fig. 2, the cooling water tube further includes a connecting member 31 and a stabilizing member 32, and the tube body 1 is connected to the cooling system through the connecting member 31; one end of the stabilizing piece 32 is fixedly connected with the connecting piece 31, the other end of the stabilizing piece is sleeved on the outer wall of the pipe body 1, the connecting part of the pipe body 1 is fixed through the stabilizing piece 32, the stability of the pipe body 1 at the connecting part is kept, shaking of the pipe body 1 caused by liquid flowing is reduced, leakage of cooling liquid caused by connection looseness at the connecting part is avoided, and the cooling effect is weakened.
After guaranteeing that the structure of inlet and outlet liquid department is stable, the cooperation degree of stabilizer 32 and body 1 also can influence the stability of body 1, in an embodiment, as shown in fig. 2, the one end that stabilizer 32 kept away from connecting piece 31 is provided with snap ring 321, snap ring 321 cooperates with the trough of body 1, when making stabilizer 32 cover establish in body 1 outside, utilizes connecting piece 31 to reduce the flexibility of body 1 in this within range, further strengthens the steady supporting effect of connecting piece 31 and body 1.
In order to enable the pipe body 1 to have good performance in a narrow space, in an embodiment, the pipe body 1 is made of nylon materials, so that the pipe body 1 has certain flexibility and toughness, meanwhile, the sine wave structure of the pipe body 1 can enable the pipe body 1 to be freely bent, the whole pipe body is convenient to assemble, the whole pipe body made of the nylon materials is light in weight, the weight of the whole pipe body can be effectively reduced, the condition of energy waste is avoided, and the energy storage capacity of a battery is improved.
