Description

Technical Field

[0001] This utility model belongs to the field of refrigeration equipment technology, and more specifically, it relates to a three-pronged tubular refrigeration device. Background Technology

[0002] Semiconductor cooling chips operate based on the Peltier effect, exhibiting the characteristics of absorbing heat at the cold end and releasing heat at the hot end. Due to their simple structure and noiseless operation, they are considered for use in small air cooling devices. However, existing air cooling products using semiconductor cooling chips generally suffer from an unreasonable design of the heat dissipation paths between the cold and hot ends. Specifically, the cooling and heating generated at the cold and hot ends are difficult to effectively isolate in the airflow path or structural heat transfer path, causing waste heat generated at the hot end to easily flow back to the cooling chip itself or the area of ​​the cooled airflow.

[0003] The aforementioned defects in the intersecting heat paths prevent the heat accumulated at the hot end from dissipating in a timely manner, causing a significant increase in the operating temperature of the cooling element (especially the hot end temperature). This directly leads to the cooling element overheating and exceeding its safe operating range, resulting in a substantial decrease in stability and reliability, severely restricting the application of this technology in air cooling scenarios requiring efficient and stable cooling. Therefore, in view of this, this study researches and improves upon the existing structure and its shortcomings, providing a three-pronged tubular cooling device to achieve greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a three-pronged tubular refrigeration device, which is achieved by the following specific technical means: A three-pronged tubular refrigeration device includes a main housing. An air inlet pipe is provided at one end of the main housing, and a cold exhaust pipe and a heat exhaust pipe are arranged in a cross shape at the other end of the main housing. A cold conduction pipe and a heat conduction pipe are respectively installed inside the cold exhaust pipe and the heat exhaust pipe. A heat conduction air inlet is provided at one end of each of the cold exhaust pipe and the heat conduction pipe, and multiple sets of heat conduction fins are provided inside each heat conduction air inlet. A fixing plate is fixedly installed between two sets of heat conduction air inlets, and a refrigeration fin is fixedly installed in the middle of the fixing plate.

[0005] Furthermore, the exhaust pipes, heat exhaust pipes, and air inlet pipes are connected to the main casing.

[0006] Furthermore, the central axis of the air inlet pipe is directly aligned with the fixing plate between the exhaust pipe and the heat exhaust pipe.

[0007] Furthermore, a fan is installed at the end of the air inlet duct.

[0008] Furthermore, multiple sets of fins are provided on both the inner and outer sides of the cooling pipe and the heat pipe.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model uses a fan to drive strong air into the air inlet pipe, and utilizes a fixed plate inside the main housing to force and clearly divert the airflow to the cross-distributed paths of the cold exhaust pipe and the heat exhaust pipe. This ensures the physical isolation of the airflow from the cold exhaust pipe that generates cold air from the heat exhaust pipe that carries away heat in terms of spatial path and airflow flow, eliminating the cross-contamination of the cold end airflow by the hot end exhaust gas of the cooling chip, and solving the core problem of heat path intersection in the prior art.

[0010] 2. This utility model has multiple sets of fins and multiple sets of heat-conducting plates on both the inner and outer sides of the cooling pipe and the heat-conducting pipe, which effectively increases the heat exchange area. Combined with the high-intensity forced airflow driven by the fan, it can quickly remove the cold energy on the surface of the cooling pipe in the exhaust pipe and efficiently output the cooling airflow. On the other hand, it can powerfully flush the surface of the heat-conducting pipe and fins in the exhaust pipe, and quickly, efficiently and in large quantities dissipate the waste heat generated at the hot end of the cooling chip. This can effectively prevent heat accumulation at the hot end and ensure that the operating temperature of the cooling chip is stable within a safe range, thereby greatly improving the cooling performance, operational stability and long-term reliability of the device.

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0020] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0022] Example:

[0023] As attached Figure 1 To be continued Figure 7 As shown: This utility model provides a three-pronged tubular refrigeration device, including a main housing 1. An air inlet pipe 2 is provided at one end of the main housing 1, and a cold exhaust pipe 3 and a heat exhaust pipe 4 are arranged in a cross shape at the other end of the main housing 1 to form a "three-pronged" layout, avoiding the cross mixing of cold and hot airflow paths. A cold conduction pipe 7 and a heat conduction pipe 6 are respectively installed inside the cold exhaust pipe 3 and the heat conduction pipe 4. A heat conduction air inlet head is provided at one end of each of the cold exhaust pipe 7 and the heat conduction air inlet head, and multiple sets of heat conduction plates 10 are provided inside each heat conduction air inlet head to increase the contact area with the airflow and the heat exchange efficiency, so that the cold end can transfer the cold energy to the airflow flowing through the cold exhaust pipe more quickly, and the hot end can transfer the waste heat to the airflow flowing through the heat exhaust pipe more efficiently so that it is carried away. A fixing plate 8 is tightly fixed between the two sets of heat conduction air inlets, and a refrigeration plate 9 is fixedly installed in the middle of the fixing plate 8. A fan 5 is installed at the end of the air inlet pipe 2.

[0024] The exhaust pipe 3, exhaust pipe 4, and air inlet pipe 2 are connected to the main housing 1 to ensure that the airflow generated by the fan 5 can smoothly enter the main housing 1 from the air inlet pipe 2, and then be diverted and discharged through the exhaust pipe 3 and exhaust pipe 4 respectively, forming a complete and isolated cold and hot airflow channel.

[0025] The central axis of the air inlet pipe 2 is aligned with the fixed plate 8 between the exhaust pipe 3 and the heat exhaust pipe 4, which separates the internal air inlet cavity of the main housing 1 and acts as a core physical isolation barrier. This allows the airflow entering the main housing to be strictly divided into two streams: one stream flows only to the cold end area connected to the cool pipe 7 and the exhaust pipe 3, and the other stream flows to the hot end area connected to the heat pipe 6 and the heat exhaust pipe 4. This completely blocks the mixing path of cold and hot airflows within the main housing 1, ensuring the purity of the cold air and the effective dissipation of heat.

[0026] The inner and outer sides of the cooling pipe 7 and the heat pipe 6 are equipped with multiple sets of fins, which increases the effective heat exchange surface area with the airflow. This significantly improves the cooling efficiency of the cold end and the heat dissipation efficiency of the hot end, resulting in lower cold air temperature and faster and more thorough heat dissipation at the hot end, thereby effectively maintaining the cooling element 9 within the safe operating temperature range.

[0027] The working principle of this embodiment: During operation, a high-speed forced airflow is generated by a fan 5 installed at the end of the air inlet duct 2. This airflow is blown directly into the internal air inlet cavity of the main housing 1 along the axial direction of the air inlet duct 2. After entering the main housing 1, the airflow is physically separated into two independent paths by the fixing plate 8: An airflow enters the area of ​​the cooling pipe 7 connected to the cold end of the cooling chip 9: The airflow flows through the heat-conducting air inlet at the end of the cooling pipe 7 and its internal multiple sets of heat-conducting fins 10, while simultaneously scouring the multiple sets of fins set on the inner and outer sides of the cooling pipe 7. During this process, the airflow and the cooling pipe 7 exchange heat fully and efficiently, absorbing the cold energy generated by the cold end of the cooling chip 9, and the temperature drops significantly, forming a low-temperature cooling airflow, which is finally discharged in a direction through the exhaust pipe 3 to supply the space that needs to be cooled. Another airflow enters the area of ​​the heat pipe 6 connected to the hot end of the cooling chip 9: The airflow flows through the heat-conducting air inlet at the end of the heat pipe 6 and the internal heat-conducting fins 10, and strongly washes the multiple sets of fins densely distributed inside and outside the heat pipe 6. In this process, the airflow efficiently absorbs and carries away the waste heat generated by the hot end of the cooling chip 9, forming a high-temperature heat dissipation airflow, which is finally discharged to the external environment through the heat exhaust pipe 4.

[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
