Obviously, the described embodiments are part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of the present application.

[0023] The embodiment of the present application discloses a tube belt inclined arrangement automobile condenser assembly. Referring to Figures 1 to 5The application discloses a tube and belt inclined arrangement automobile condenser assembly which comprises a condenser fan 3, a collecting pipe one 1 and a collecting pipe two 2, a plurality of inclined grooves 11 are formed on the opposite sides of the collecting pipe one 1 and the collecting pipe two 2, the inclined angle of the grooves 11 is designed according to the best fluid mechanics, the opposite sides of the grooves 11 are provided with a plurality of connecting holes (not shown in the figure), a flat tube 4 is connected between the two grooves 11 oppositely formed on the collecting pipe one 1 and the collecting pipe two 2, a cavity 41 is formed in the flat tube 4 and the cavity 41 is communicated with the two grooves 11 oppositely formed, the flow of refrigerant in the flat tube 4 is smooth, the width direction of the flat tube 4 is not perpendicular to the length direction of the collecting pipe one 1 and the collecting pipe two 2, a fin 5 is detachably arranged between the two adjacent flat tubes 4, a dryer cylinder 6 is arranged at the connecting hole of the collecting pipe one 1 and is used for absorbing the moisture and impurities in the refrigerant, the existence of the dryer cylinder 6 is helpful to protect the normal operation of the condenser and the whole refrigeration system, and a pressing plate 7 is arranged at the connecting hole of the collecting pipe two 2 and is used for improving the stability and reliability of the condenser and preventing the parts from loosening or falling off.

[0024] In this way, through the tube and belt inclined arrangement, the size of the flat tube 4 and the fin 5 is increased through the inclined arrangement without changing the thickness of the condenser core, the heat dissipation area of the core is increased, the air flow is smoother, and the heat dissipation efficiency of the condenser is improved; meanwhile, the inclined arrangement is helpful to reduce the vortex and dead zone at the back of the condenser, more air can flow through the surface of the flat tube 4 and the fin 5, and the heat dissipation amount is increased. The design realizes the efficient heat dissipation effect and the stable operation of the system, meanwhile, the detachable fin 5 design is convenient for maintenance and replacement, and the problem that the heat dissipation amount of the traditional condenser assembly is difficult to improve without changing the thickness of the condenser core and the cooling effect of the condenser assembly is influenced is effectively solved.

[0025] Specifically, referring to Figure 5 The flat tube 4 is fixedly connected with a plurality of staggered and spaced apart barrier strips 42 in the cavity 41, the plurality of barrier strips 42 divide the cavity 41 into a serpentine flow channel, and the two grooves 11 oppositely formed on the collecting pipe one 1 and the collecting pipe two 2 are arranged at the two ends of the serpentine flow channel.

[0026] The material of the flat tube 4 has good thermal conductivity and corrosion resistance to ensure smooth flow and efficient heat dissipation of the refrigerant therein; the barrier strips 42 are strip-shaped structures fixed in the cavities 41 of the flat tube 4, which are arranged staggered and spaced to form complex serpentine flow channels, the material of the barrier strips 42 should match the flat tube 4 to ensure firm connection and sealing between them, and the number and shape of the barrier strips 42 can be adjusted according to actual needs to achieve the best refrigeration effect and heat dissipation performance; through the separation of the barrier strips 42, the cavities 41 in the flat tube 4 are divided into multiple interconnected serpentine flow channels, the refrigerant enters the serpentine flow channels in the flat tube 4 from the slot holes 11 of the header one 1, and flows through a series of tortuous flow to flow out from the slot holes 11 of the header two 2, so that the flow of the refrigerant therein is more sufficient and uniform, the flow path and residence time of the refrigerant in the flat tube 4 are increased, and the heat exchange between the refrigerant and the fins 5 is more sufficient. The arrangement of the barrier strips 42 not only optimizes the flow path of the refrigerant, but also enhances the structural stability of the flat tube 4 to some extent, avoiding deformation or rupture of the flat tube 4 under the action of high-pressure refrigerant, and ensuring long-term stable operation of the condenser.

[0027] And, referring to Figure 5 , the flat tube 4 is provided with heat dissipation holes 421 extending into the barrier strips 42 at positions corresponding to the barrier strips 42, the heat dissipation holes 421 are not in communication with the serpentine flow channels, the presence of the heat dissipation holes 421 increases the contact area between the refrigerant and the surrounding air, thereby improving the heat exchange efficiency, when the refrigerant flows in the flat tube 4, its heat can be more quickly transferred to the surrounding air through the heat dissipation holes 421, achieving more efficient heat dissipation, further enhancing the heat dissipation performance of the automobile condenser assembly, improving its overall efficiency and reliability.

[0028] And, referring to Figure 1 , the lower end surface of the flat tube 4 is provided with a wind shield 31 for shielding a plurality of heat dissipation holes 421, the free end of the wind shield 31 is fixedly connected with the output end of the condenser fan 3. The wind shield 31 has a shape and size matching the lower end surface of the flat tube 4 to ensure close fitting and effective shielding, through the guidance of the wind shield 31, the airflow generated by the condenser fan 3 can pass through the flat tube 4 and the heat dissipation holes 421 more efficiently, and exchange heat with the refrigerant sufficiently, which helps to improve the heat dissipation efficiency of the condenser and reduce the energy consumption of the refrigeration system; at the same time, the design of the wind shield 31 can also reduce the turbulence and loss of airflow at the flat tube 4 and the fins 5, and improve the overall heat dissipation performance. This design not only improves the heat dissipation efficiency, but also enhances the structural stability and reliability of the condenser, further optimizes the heat dissipation performance of the automobile condenser assembly.

[0029] Further, referring to Figure 1 and Figure 2The opposite side of the two adjacent flat tubes 4 is fixed with two buckles 43 along the length direction, and the two sides of the fins 5 are fixed with clamping strips 51, and the fins 5 are connected and installed on the flat tubes 4 through the clamping connection of the clamping strips 51 and the buckles 43.

[0030] By arranging the buckles 43 on the opposite side of the two adjacent flat tubes 4 and arranging the clamping strips 51 on the two sides of the fins 5, the clamping connection design between the fins 5 and the flat tubes 4 is realized, which not only simplifies the assembly process of the condenser, but also improves the connection stability and heat dissipation efficiency between the fins 5 and the flat tubes 4. This design helps to ensure the stability and reliability of the condenser during installation and use, and improves the performance of the entire refrigeration system.

[0031] At the same time, referring to Figure 1 , Figure 2 and Figure 3 , the dryer cylinder body 6 and the collecting pipe two 2 are fixed with supports 8 on the side away from the flat tubes 4, and the supports 8 are support structures connecting the dryer cylinder body 6 and the collecting pipe two 2, which can enhance the connection strength between the dryer cylinder body 6 and the collecting pipe two 2, prevent them from loosening or damaging in high-pressure refrigerant or vibration environment; and through the supports 8, the condenser assembly can be more easily installed on the vehicle and fixedly connected with other components, which helps to ensure the stability and reliability of the condenser assembly during vehicle driving.

[0032] In addition, referring to Figure 1 and Figure 2 , the lower end surface of the support 8 is provided with a rubber pad 81 made of rubber material with high elasticity, wear resistance, corrosion resistance and high temperature resistance, which can further improve the installation stability and shock absorption performance of the automobile condenser assembly. This design not only helps to ensure the stability and reliability of the condenser assembly during installation and use, but also protects the installation surface from scratching or wear, improves the overall service life and aesthetics.

[0033] The implementation principle of the automobile condenser assembly with tube and fin arrangement in the embodiment of the present application is as follows:

[0034] Through the tube and fin arrangement, the size of the flat tubes 4 and the fins 5 is increased by the inclined arrangement without changing the thickness of the condenser core, thereby increasing the heat dissipation area of the core, making the air flow more smooth, and improving the heat dissipation efficiency of the condenser; at the same time, the inclined arrangement also helps to reduce the vortex and dead zone at the back of the condenser, so that more air can flow through the surface of the flat tubes 4 and the fins 5, thereby increasing the heat dissipation amount. This design realizes efficient heat dissipation effect and stable operation of the system, and the detachable fin 5 design is also convenient for maintenance and replacement, effectively improving the problem that the traditional condenser assembly is difficult to improve the heat dissipation amount without changing the thickness of the condenser core, affecting the cooling effect of the condenser assembly.
