Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a refrigerated structure for a center console armrest. Background Technology

[0002] With the continuous advancement of automotive technology and the increasing demands of consumers for driving and riding quality, in-vehicle refrigeration has gradually become an important comfort and convenience feature in mid-to-high-end models. Typically, this refrigerated space is integrated into easily accessible locations such as the center armrest area, behind the rear center armrest, or in the door storage compartments, primarily for refrigerating beverages, food, or other items requiring low-temperature preservation during driving or parking.

[0003] Currently, one of the main technical approaches to achieving in-vehicle refrigeration is to utilize the vehicle's existing air conditioning system for cooling. The basic principle is to guide the cooling energy generated by the air conditioning system to the interior of a dedicated refrigerated compartment through air ducts, refrigerant pipelines, or heat exchangers, thereby cooling the space inside. For example, Chinese invention patent application CN116653737A discloses an in-vehicle refrigerator that utilizes the low-temperature refrigerant from the vehicle's air conditioning system to directly or indirectly cool the refrigerated compartment, achieving integrated design with the vehicle's overall air conditioning system. This design offers advantages such as compact structure and high cooling efficiency.

[0004] However, existing center console refrigeration systems are highly dependent on the continuous operation of the vehicle's powertrain and air conditioning compressor. When the vehicle is temporarily turned off, the compressor stops, refrigerant circulation is interrupted, and the air conditioning system cannot continue to effectively generate cooling. The refrigerated space thus loses a continuous source of cooling. This causes temperature fluctuations and rebounds within the refrigerated space, affecting not only the refrigeration effect but also leading to a decline or even spoilage of temperature-sensitive beverages, medicines, or fresh food, thus diminishing the user's experience and trust in the in-vehicle refrigeration function.

[0032] The refrigerator is equipped with a drawer opening at the rear end;

[0033] The refrigerated drawer is slidably positioned within the refrigerator via its drawer opening.

[0034] The central armrest refrigeration structure of this utility model has the following advantages over the prior art:

[0035] (1) By connecting the condenser pipe to the original vehicle air conditioning system, efficient main cooling is achieved during normal vehicle operation. At the same time, a semiconductor refrigeration module is added as an auxiliary cold source. When the vehicle is temporarily turned off, this module can continuously supplement the cooling of the refrigerated space, effectively suppressing temperature rise and significantly reducing temperature fluctuations in the refrigerated space, ensuring the continuity and stability of the refrigeration effect. In addition, the heat generated by the hot end of the semiconductor refrigeration module is discharged to the engine compartment through the heat dissipation pipe, realizing the rational setting of the semiconductor refrigeration module. This not only helps to improve the supplementary cooling effect of the semiconductor refrigeration module, but also avoids affecting the temperature inside the cabin, thus improving the user experience.

[0036] (2) By setting a first embedding hole and a second embedding hole at the front end of the refrigerator, respectively for installing the cold end and condenser tube of the semiconductor refrigeration module, the two refrigeration sources are concentrated and precisely embedded in the side wall of the cabinet. The first embedding hole is located above the second embedding hole. By utilizing the characteristic of cold air naturally sinking, the cold energy generated by the semiconductor refrigeration module is preferentially applied to the upper part of the refrigerator space, thereby improving the refrigeration efficiency.

[0037] (3) By setting heat exchange fins at the cold end of the semiconductor refrigeration module and forming a downward vertical bend at the end of the heat exchange fins, the heat exchange area is increased and the heat conduction effect is enhanced. The gap between adjacent fins not only helps to adapt to thermal expansion and contraction, but also allows each fin to be fully exposed to the refrigeration environment, further improving the heat conduction efficiency.

[0038] (4) By fixing the protective cover to the outer wall of the front end of the refrigerator, the hot end area of ​​the semiconductor refrigeration module is effectively surrounded, forming a concentrated hot air guiding cavity, which prevents heat from spreading to other areas of the central armrest box and improves thermal management efficiency. At the same time, since the second embedded hole is a through hole, the condenser tube is at least partially exposed in the outer shell of the central armrest box, so that the low temperature air in the outer shell can enter the protective cover through the top ventilation port to participate in the cooling of the hot end of the semiconductor refrigeration module, further improving the cooling effect.

[0047] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0048] like Figure 1-6 As shown, the present invention provides a central armrest box refrigeration structure, which includes a central armrest box 1, a condenser pipe 2, a semiconductor refrigeration module 3, a protective cover 4, and a heat dissipation pipe 5.

[0049] The central armrest box 1 has a refrigerated space 101 inside; the condenser pipe 2 is embedded in the side wall of the refrigerated space 101, and its two ends are connected to the refrigerant circulation pipe of the car air conditioning system through pipes; when the vehicle is driving normally and the air conditioning system is running, the low temperature refrigerant flows through the condenser pipe 2 to achieve the main cooling of the refrigerated space 101, with high cooling efficiency.

[0050] The semiconductor refrigeration module 3 is powered by the vehicle's onboard battery. Its cold end is embedded in the side wall of the refrigerated space 101, while its hot end is placed inside the protective cover 4. When the vehicle is temporarily turned off or the air conditioning compressor stops, the semiconductor refrigeration module 3 is activated by the vehicle's power supply or a backup battery to continuously supplement the cooling of the refrigerated space 101, effectively suppressing temperature rise, significantly reducing temperature fluctuations, and ensuring the continuity and stability of the refrigeration effect. The semiconductor refrigeration module 3 can be a TEC1-12706 thermoelectric cooling element. For pneumatic convenience, a start / stop button can be installed inside the vehicle compartment, connected to the power supply circuit of the semiconductor refrigeration module 3, to control the energization and de-energization of the module.

[0051] The protective cover 4 is fixed inside the center armrest box 1 to isolate the heat from the hot end; one end of the heat dissipation pipe 5 is connected to the inside of the protective cover 4 and the other end is connected to the engine compartment. An exhaust fan 51 (such as a DC12V axial flow exhaust fan) is embedded inside the pipe, which can force the heat generated by the hot end of the semiconductor cooling module 3 to be discharged to the engine compartment, so as to avoid heat accumulation affecting the module performance and prevent heat from entering the passenger compartment, thereby improving driving and riding comfort.

[0052] In the aforementioned refrigerated center console structure, the center console 1 includes an outer shell 11, a refrigerated compartment 12, and a lid 13. The outer shell 11, as a single structural component, is hollow inside and used to install and support internal components. Its lower end is used to securely connect to the aisle area between the front seats of the car. The refrigerated compartment 12 is located inside the rear side of the outer shell 11. Its upper end extends upward to the top of the outer shell 11 and is fixedly connected, and its rear end extends backward to the rear end of the outer shell 11 and is fixedly connected, resulting in a stable structure with good vibration resistance. Simultaneously, the hollow interior of the refrigerated compartment 12 forms a refrigerated space 101 for storing items requiring low-temperature preservation. The top of the refrigerated compartment 12 is open, and the lid 13 covers this opening and is hinged to the top of the refrigerated compartment 12. Users can easily open the lid 13 with one hand to access items, and when closed, it seals the refrigerated space 101, reducing cold air loss.

[0053] Furthermore, both ends of the condenser pipe 2 and the heat dissipation pipe 5 extend forward through the front end of the outer casing 11 and into the engine compartment. This facilitates the connection of the condenser pipe 2 with the air conditioning refrigerant lines in the engine compartment and allows the heat dissipation pipe 5 to be directly connected to the compartment for convenient heat exhaust. The exhaust fan 51 is located inside the heat dissipation pipe 5 and can actively extract and exhaust hot air, improving heat dissipation efficiency and ensuring that the semiconductor cooling module 3 can still operate efficiently when the engine is off.

[0054] To facilitate the arrangement of the two ends of the condenser pipe 2 and the heat dissipation pipe 5, an opening is provided at the bottom front end of the outer casing 11, through which the two ends of the condenser pipe 2 and the heat dissipation pipe 5 are led out of the outer casing 11. At the same time, the interior of the outer casing 11 is connected to the interior of the carriage through this opening.

[0055] In addition, the front end of the refrigerator 12 is provided with a first embedding hole 1201 for embedding the cold end of the semiconductor refrigeration module 3, and a second embedding hole 1202 for embedding the condenser tube 2. The first embedding hole 1201 is located above the second embedding hole 1202, and both embedding holes are through holes.

[0056] This structure allows for a concentrated and compact arrangement of the condenser tube 2 and the semiconductor refrigeration module 3 in the front end area of ​​the refrigerator 12, facilitating assembly and sealing and improving production efficiency. The first embedding hole 1201 is positioned at the top, ensuring that the cold end of the semiconductor refrigeration module 3 acts on the upper region of the refrigeration space 101. Due to the higher density of cold air, it naturally sinks; the released cold air diffuses evenly from top to bottom along the refrigeration space 101, forming an effective air convection circulation. This significantly improves the uniformity and overall efficiency of refrigeration, prevents excessively high local temperatures, and optimizes refrigeration performance.

[0057] In the aforementioned refrigerated center armrest box structure, the protective cover 4 is fixed to the outer wall at the front end of the refrigerated box 12, completely covering the hot end area of ​​the semiconductor cooling module 3 to form a closed hot air guiding cavity. This effectively prevents heat from spreading to other areas of the center armrest box 1, improves thermal management efficiency, and avoids localized overheating that could affect the user experience.

[0058] In addition, the protective cover 4 has an exhaust port 401 at the bottom and an air exchange port 402 at the top. One end of the heat dissipation pipe 5 is embedded in the exhaust port 401, so that the protective cover 4 and the heat dissipation pipe 5 are connected through the exhaust port 401. The protective cover 4 and the outer casing 11 are connected through the air exchange port 402. When the exhaust fan 51 is started, hot air is drawn out from the bottom exhaust port 401, and relatively low-temperature air from outside enters the interior of the protective cover 4 from the top air exchange port 402, forming a forced convection from bottom to top, which significantly improves the heat dissipation efficiency of the hot end of the semiconductor cooling module 3 and ensures its stable operation for a long time.

[0059] The portion of the condenser tube 2 embedded in the second embedding hole 1202 is coiled, with straight tubes at both ends extending forward to connect to the refrigerant circulation pipe of the automotive air conditioning system. For example... Figure 4 As shown, since the second embedded hole 1202 is a through hole, at least part of the condenser tube 2 (such as the front end of the coil section) is exposed in the outer shell 11 of the central armrest box 1, which can cool the air in the outer shell 11 and lower its temperature. This low-temperature air can enter the protective cover 4 through the top ventilation port 402 to participate in the cooling of the hot end of the semiconductor cooling module 3 and improve the cooling effect.

[0060] Furthermore, the bottom of the cover 4 is provided with two guide slopes 41 on both sides, and the exhaust port 401 is located between the two guide slopes 41. The hot airflow generated at the hot end can be guided to the middle area through the guide slopes 41 and concentrated into the exhaust port 401, reducing airflow diffusion and eddy loss, improving exhaust efficiency, ensuring that heat is efficiently and directionally discharged, and making the cooling effect better.

[0061] In the above-mentioned central armrest box refrigeration structure, the cold end of the semiconductor refrigeration module 3 is fixed with a number of heat exchange fins 31. These heat exchange fins 31 are located inside the first embedded hole 1201, and the end of these heat exchange fins 31 near the refrigeration space 101 is bent vertically downward (i.e. bent downward at 90 degrees) to form a bent part 311, thereby increasing the heat exchange area and enhancing the heat conduction effect.

[0062] In addition, gaps are reserved between the bent portion 311 and the adjacent heat exchange fins 31. These gaps not only help to accommodate thermal expansion and contraction, but also allow each fin to be fully exposed to the refrigeration environment, further improving heat conduction efficiency. Furthermore, after bending, the rear end of the bent portion 311 is aligned with the front end of the refrigeration space 101.

[0063] In the aforementioned central armrest box refrigeration structure, the central armrest box 1 also includes a refrigeration drawer 14. The rear end of the refrigeration box 12 is provided with a drawer opening 1203; the refrigeration drawer 14 is slidably disposed in the refrigeration box 12 through the drawer opening 1203.

[0064] In this structure, the interior of the refrigerated drawer 14 is connected to the refrigerated space 101 to maintain a low-temperature environment. Users can quickly access frequently used items without opening the main compartment lid 13, improving ease of use. The drawer opening 1203 is equipped with a sealing strip to reduce cold loss and optimize energy efficiency.

[0065] The method of using the central armrest box refrigeration structure of this utility model is as follows:

[0066] When the vehicle is in normal operation and the air conditioning system is running, the low-temperature refrigerant flows through the condenser pipe 2 to provide primary cooling for the refrigerated compartment 101. When the vehicle is temporarily turned off and the air conditioning compressor stops, and supplemental cooling is needed, the semiconductor refrigeration module 3 is powered on to operate, continuously supplementing cooling for the refrigerated compartment 101 through its cold end. The heat generated by the hot end of the semiconductor refrigeration module 3 is sent into the engine compartment by the exhaust fan 51 through the heat dissipation pipe 5. When supplemental cooling is not needed, the semiconductor refrigeration module 3 is powered off.

[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
