Description

Technical Field

[0001] This utility model relates to the technical field of heat exchangers, and in particular to a novel heat exchanger with an eccentrically perforated mounting plate. Background Technology

[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid. In the automotive field, it is divided into radiators, air-to-air intercoolers, evaporators, condensers, and oil coolers. Automotive radiators belong to the automotive cooling system.

[0003] Existing heat exchangers, such as the protective plate for automotive heat exchangers disclosed in utility model patent application number 201120048847.9, have the following main structure: the heat exchanger body is provided with a main plate, the two ends of the protective plate are configured to be snap-fit ​​connected to the main plate of the heat exchanger body, the protective plate is provided with a snap-fit ​​for connecting to the condenser, and the middle part of the protective plate is provided with a ligament area having two long flat holes or V-shaped grooves distributed in a figure-eight shape.

[0004] However, the mounting plates of traditional heat exchangers are mostly tightly fitted to the heat exchanger base plate. If there is interference from other parts, it is impossible to avoid them flexibly, which will affect the overall layout and structure of the vehicle body. Moreover, the weld area at the connection between the traditional mounting plate and the heat exchanger base plate is prone to heat accumulation, which may lead to thermal failure of the brazing material and bring certain risks. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a new type of heat exchanger with an eccentrically perforated mounting plate, which not only allows the heat exchanger to avoid the high-heat areas or crowded wiring harness areas of the vehicle body, optimizes the thermal management layout, adapts to irregular vehicle body spaces, and improves installation freedom, but also maintains the heat exchange temperature difference and improves the actual heat exchange efficiency.

[0006] This utility model discloses a novel heat exchanger with an eccentrically perforated mounting plate, comprising a heat exchanger and a mounting bracket, which is installed on the heat exchanger and facilitates the fixing of the heat exchanger. The operator welds the mounting bracket to the heat exchanger and then uses bolts to fix the mounting bracket to the vehicle body. This not only increases the distance between the heat exchanger and the high-temperature vehicle body, enhancing the heat dissipation effect, but also optimizes the thermal management layout.

[0007] Preferably, the heat exchanger includes a heat exchanger body and a heat exchanger base plate. The heat exchanger body is connected to the vehicle's thermal management system, and the heat exchanger base plate is installed on the heat exchanger body. The heat exchanger body facilitates the control and regulation of the vehicle's thermal management system, and the heat exchanger base plate protects the heat exchanger body.

[0008] Preferably, the mounting bracket includes an eccentric plate and mounting legs. The eccentric plate and the heat exchanger base plate are eccentrically welded, and the mounting legs and the eccentric plate are integrally forged. The mounting legs are connected to the vehicle body by bolts, thereby fixing the heat exchanger. The eccentric welding of the eccentric plate and the heat exchanger base plate can act as a flexible buffer zone to absorb high-frequency vibrations during vehicle operation, reducing the risk of vibrations being directly transmitted to the heat exchanger body and preventing the failure of brazed joints or plates due to long-term vibration fatigue. Moreover, the eccentric design allows the heat exchanger to avoid high-heat areas or congested wiring harness areas of the vehicle body, optimizing the thermal management layout. By adjusting the spacing angle, it can adapt to irregular vehicle body spaces, increasing the degree of installation freedom. Furthermore, the eccentric plate has a certain thickness, which can increase the distance between the heat exchanger body and the high-temperature vehicle body, significantly reducing the preheating of the inlet fluid caused by radiative heat transfer, maintaining the heat exchange temperature difference, and improving the actual heat exchange efficiency.

[0009] Preferably, multiple sets of through holes are also provided on the eccentric plate and the mounting legs; the porous structure formed by the holes can disperse the stress concentration phenomenon of the mounting bracket, reduce the risk of local deformation, and reduce the weight, which is in line with the trend of lightweight vehicle equipment. In addition, the holes form a through air channel, which works in conjunction with the eccentric spacing to accelerate the convection of hot and cold air. External cold air can directly contact the high-temperature base plate through the holes, reduce the temperature of the base plate, and reduce the impact of heat radiation on the vehicle body.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the staff welds the mounting bracket onto the heat exchanger and then uses bolts to fix the mounting bracket onto the vehicle body. This not only increases the distance between the heat exchanger and the high-temperature vehicle body, enhancing the heat dissipation effect, but also optimizes the thermal management layout.

[0016] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0017] Example 1

[0018] This utility model discloses a novel heat exchanger with an eccentrically perforated mounting plate, comprising a heat exchanger 01 and a mounting bracket 02, which is mounted on the heat exchanger 01 for easy fixation. The heat exchanger 01 includes a heat exchanger body 11 and a heat exchanger base plate 12. The heat exchanger body 11 is connected to the vehicle's thermal management system, and the heat exchanger base plate 12 is mounted on the heat exchanger body 11. The mounting bracket 02 includes an eccentric plate 21 and mounting legs 22. The eccentric plate 21 and the heat exchanger base plate 12 are eccentrically welded, and the mounting legs 22 and the eccentric plate 21 are integrally forged. During operation, the mounting legs 22 are first connected to the vehicle body via bolts, thereby fixing the heat exchanger 01. The heat exchanger body 11 facilitates adjustment by controlling the vehicle's thermal management system. The heat exchanger body 11 is protected by a heat exchanger base plate 12. The eccentric plate 21 and the heat exchanger base plate 12 are eccentrically welded. The eccentric spacing can act as a flexible buffer to absorb high-frequency vibrations during vehicle operation, reducing the risk of vibrations being directly transmitted to the heat exchanger body 11. This prevents brazing points or plates from failing due to long-term vibration fatigue. Moreover, the eccentric design allows the heat exchanger to avoid high-heat areas or congested wiring harness areas of the vehicle body, optimizing the thermal management layout. By adjusting the spacing angle, it can adapt to irregular vehicle body spaces, increasing installation freedom. Furthermore, the eccentric plate 21 has a certain thickness, which can increase the distance between the heat exchanger body 11 and the high-temperature vehicle body, significantly reducing the preheating of the inlet fluid caused by radiative heat transfer, maintaining the heat exchange temperature difference, and improving the actual heat exchange efficiency.

[0019] Example 2

[0020] like Figures 1 to 4As shown, this utility model discloses a novel heat exchanger with an eccentrically perforated mounting plate, based on embodiment 1. It further includes multiple sets of through holes on both the eccentric plate 21 and the mounting legs 22. During operation, the mounting legs 22 are first connected to the vehicle body via bolts, thereby fixing the heat exchanger 01. The heat exchanger body 11 is easily controlled by the vehicle's thermal management system. The heat exchanger body 11 is protected by a heat exchanger base plate 12. The eccentric plate 21 and the heat exchanger base plate 12 are eccentrically welded, and the eccentricity acts as a flexible buffer zone, absorbing high-frequency vibrations during vehicle operation and reducing the risk of vibrations being directly transmitted to the heat exchanger body 11. This prevents brazing joints or plates from failing due to long-term vibration fatigue. Furthermore, the eccentric design allows the heat exchanger to avoid the high-heat areas of the vehicle body. In areas with congested wiring harnesses, the thermal management layout is optimized. By adjusting the spacing angle, it can adapt to irregular vehicle body spaces, increasing installation freedom. Furthermore, the eccentric plate 21 has a certain thickness, which can increase the distance between the heat exchanger body 11 and the high-temperature vehicle body, significantly reducing the preheating of the inlet fluid caused by radiative heat transfer, maintaining the heat exchange temperature difference, and improving the actual heat exchange efficiency. The porous structure formed by the openings of the eccentric plate 21 and the mounting legs 22 can disperse the stress concentration phenomenon of the mounting bracket 02, reduce the risk of local deformation, and reduce its own weight, which is in line with the trend of lightweight vehicle equipment. In addition, the openings form a through air channel, which works in conjunction with the eccentric spacing to accelerate the convection of hot and cold air. External cold air directly contacts the high-temperature base plate through the holes, reducing the base plate temperature and reducing the impact of thermal radiation on the vehicle body.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
