Description

Novel Radiator with Coaxial Flat Tube for Hydrogen Energy
Vehicles
TECHNICAL FIELD
The invention relate to the technical field of radiators, in particular to a novel radiator with coaxial flat tube for hydrogen energy vehicles.
BACKGROUND
Radiators have been widely used in the cooling system of traditional fuel vehicles, and the technology is mature. The commonly used radiator core is 16~60 mm thick. Generally, the tank is made of plastic, and the tank and the header are sealed by rubber seals, so the sealing reliability is low. Moreover, the top tank, tank and flat tube of the existing conventional radiator are all single flow channels, which can only dissipate heat through air. Its principle is that the heat of the coolant is transferred from the flat tube to the fins, and the residual heat of the high-temperature coolant is dissipated into the air through the fins under a certain air volume. The conventional radiator is generally installed in front of the engine and cooled by a mechanical fan or an electronic fan on the air side; on the coolant side, the mechanical water pump is generally used in the cooling system, and the heat of the engine is taken away by the water flow of the cooling liquid; when the vehicle is at the maximum power point or torque point, the heat load of the engine is very high. Due to the low heat dissipation efficiency of the conventional radiator, it is necessary to increase the water flow and air volume on the vehicle side to improve the heat dissipation capacity. Otherwise, sometimes the maximum heat dissipation demand of the vehicle can not be met, which will affect the operation of the vehicle. Increasing the water flow and air volume will not only increase the power consumption and noise of the vehicle, but also increase the cost and the reliability of product operation. Therefore, a novel radiator with coaxial flat tube for hydrogen energy vehicles is proposed to solve the above problems.

In the process of heat exchange between the low-temperature waste water in the inner channel of the coaxial flat tube 1 and the surrounding high-temperature coolant through the tube wall, the residual heat of the coaxial flat tube 1 after heat dissipation is absorbed by the fins 2, and then is blown to the fins 2 by a certain air volume for heat dissipation, so that the heat dissipation efficiency of the device is improved.
Embodiment 3
As shown in Figs. 1-3, in order to solve the problem that it is not convenient to exchange heat between low-temperature waste water and high-temperature coolant, the coaxial flat tube 1 is provided with inner and outer double flow channels, and the coaxial flat tube 1 is made of aluminum; the outer flow channel of the coaxial flat tube 1 is communicated with the header 3; the top end of the inner flow channel of the coaxial flat tube 1 is communicated with the upper closed manifold assembly 5; and the bottom end of the inner flow channel of the coaxial flat tube 1 is connected with the lower closed manifold assembly 9. The low-temperature waste water flows into the inner flow channel of the coaxial flat tube 1, and the high-temperature coolant flows into the outer flow channel of the coaxial flat tube 1, which facilitates the heat exchange between the low-temperature waste water and the high-temperature coolant.
Embodiment 4
As shown in Figs. 1-2, in order to solve the problem of poor sealing performance of the device, the top tank 7 is fixedly connected with the top header 3, and the bottom tank 11 is fixedly connected with the bottom header 3. When both the top tank 7 and the bottom tank 11 are made of aluminum, the top tank 7 and the top header 3 are welded and fixed together, and the bottom tank 11 and the bottom header 3 are welded and fixed together. When both the top tank 7 and the bottom tank 11 are made of plastic materials, the top tank 7 and the top header 3 are fastened and fixed together by rubber sealing strips, and the bottom tank 11 and the bottom header 3 are fastened and fixed together, so that the sealing performance of the device is better.
Embodiment 5
As shown in Figs. 1-2, in order to solve the problem that it is inconvenient to fix the device, the left end outside the top tank 7 is connected with a left mounting bracket assembly 13 in a sliding way, and the left mounting bracket assembly 13 is connected with the bottom tank 11 in a sliding way, and the right end outside the top tank 7 is connected with a right mounting bracket assembly 14 in a sliding way; and the right mounting bracket assembly 14 is connected with the bottom tank 11 in a sliding way, the upper and lower ends outside of the left mounting bracket assembly 13 and the upper and lower ends outside of the right mounting bracket assembly 14 are both connected with bolts 15 in a spiral way; the bolts 15 at the top end are connected with the upper water tank 7 in a spiral way, and the bolts 15 at the bottom end are connected with the bottom tank 11. The left mounting bracket assembly 13 is fixed on the left side of the top tank 7 and the bottom tank 11 by bolts 15, and the right mounting bracket assembly 14 is fixed on the right side of the top tank 7 and the bottom tank 11 by bolts 15, which facilitates the fixing and installation of the device through the left mounting bracket assembly 13 and the right mounting bracket assembly 14.
In this embodiment, when using the device, the left mounting bracket assembly 13 and the right mounting bracket assembly 14 are fixed with the top tank 7 and the bottom tank 11 on the device through bolts 15, and then the device can be installed through the left mounting bracket assembly 13 and the right mounting bracket assembly 14. During the heat dissipation operation by the device, at this time, the high-temperature coolant will flow in from the liquid inlet pipe 8 of the top tank 7, flow through the outer flow channel inside the top tank 7, then flow through the outer flow channel of the coaxial flat tube 1, then flow into the outer flow channel inside the bottom tank 11, and finally flow out from the liquid outlet pipe 12 of the bottom tank 11. At this time, the low-temperature waste water will flow in from the water inlet pipe 6 of the upper closed manifold assembly 5, then flow into the inner flow channel of the coaxial flat tube 1, then flow into the lower closed manifold assembly 9, and finally flow out from the water outlet pipe 10 of the lower closed manifold assembly 9. At this time, the high-temperature coolant and the low-temperature waste water can exchange heat through the aluminum tube wall inside the coaxial flat tube 1, so as to achieve the purpose of heat dissipation. Because the flow channels of the high-temperature coolant and the low-temperature waste water are separated, they will not flow together, and the residual heat of the high-temperature coolant will finally be transferred to the fins 2 through the outer tube wall of the coaxial flat tube 1, and under the condition of a certain air volume, the residual heat of the high-temperature coolant will be dissipated into the air through the fins 2.
The above is the preferred embodiment of the present invention, and the basic principles, main features and advantages of the present invention have been shown and described above.
