Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for electrical equipment, specifically to a heat dissipation device for a cabin and a closed cabin heat dissipation system. Background Technology

[0002] In current enclosed environments, equipment generates a significant amount of heat during operation, typically requiring air conditioning for cooling. However, in practice, air conditioning is sometimes unsuitable due to limitations in the size and operating angle of the enclosed space. For example, in some compact enclosed spaces, the air conditioning system, containing a bulky compressor refrigeration unit, cannot be installed. Furthermore, within certain operating angle ranges, air conditioners installed within enclosed spaces may malfunction, failing to adequately cool the equipment and potentially causing damage due to overheating. Utility Model Content

[0003] To solve at least one of the above technical problems, this utility model provides a heat dissipation device inside the cabin and a closed cabin heat dissipation system.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This utility model provides a heat dissipation device for a cabin, including a shell, an airflow heat exchanger fixed inside the shell, a convection window opened on one side wall of the shell, a convection fan installed inside the convection window, the convection fan being used to drive airflow through the convection window and through the airflow heat exchanger; a coolant inlet port and a coolant return port are also fixed on the shell, the inlet of the airflow heat exchanger is connected to the coolant inlet port through a pipe, and the outlet of the airflow heat exchanger is connected to the coolant return port through a pipe.

[0005] The beneficial effects of this utility model are: This invention can be installed and operated within a sealed chamber. The coolant inlet and coolant return inlets can be used to connect to an external liquid cooling source, thus eliminating the need for additional space to install a compressor within the sealed chamber, resulting in a small footprint. By driving the air within the sealed chamber through a convection fan, the airflow passes through the convection window and flows through the airflow heat exchanger, achieving continuous heat dissipation of the air within the sealed chamber. After releasing heat, the airflow continues to flow away from the airflow heat exchanger, facilitating rapid cooling of the sealed chamber.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, one side of the airflow heat exchanger is attached to the inner side of one side wall of the shell, and the convection fan is directly opposite the airflow heat exchanger.

[0008] To prevent some airflow from flowing directly from the gap between the airflow heat exchanger and the shell sidewall to the convection window, it is easier to ensure that the airflow of the convection fan flows evenly through the airflow heat exchanger, thereby improving heat dissipation efficiency.

[0009] Furthermore, the outlet side of the convection fan is directly opposite the airflow heat exchanger.

[0010] This facilitates increasing the kinetic energy of the airflow passing through the airflow heat exchanger and improving the convective heat transfer rate between the air and the airflow heat exchanger.

[0011] Furthermore, the convection window is provided in multiple locations, and each convection window is equipped with a convection fan.

[0012] This facilitates increased airflow and improved heat dissipation efficiency.

[0013] Furthermore, at least one side of the housing is open.

[0014] This allows air inside the sealed chamber to enter and exit the shell from the open side, and then enter and exit the airflow heat exchanger.

[0015] Furthermore, a temperature sensor is also fixed on the housing, with the sensor's probe located outside the housing.

[0016] The temperature of the installation environment of this invention is detected by a temperature sensor, which makes it easy to judge and control the state and flow rate of the liquid cooling medium provided by the liquid cooling source, and the temperature control is convenient.

[0017] Furthermore, a power supply connector is also fixed on the housing, and the temperature sensor and convection fan are electrically connected to the power supply connector respectively.

[0018] It facilitates the supply of power to temperature sensors and convection fans.

[0019] Furthermore, the bottom wall of the housing is provided with extensions at both ends, the extensions protruding from both ends of the housing, and multiple mounting holes are provided on the extensions.

[0020] The extension and mounting holes facilitate the bolting of the shell to fixed structures such as the walls of the enclosed compartment, making installation convenient.

[0021] This utility model provides a closed chamber heat dissipation system, including a liquid cooling source and a heat dissipation device inside the chamber. The heat dissipation device inside the chamber is located inside the closed chamber, and the liquid cooling source is located outside the closed chamber. The coolant inlet is connected to the outlet of the liquid cooling source through an inlet pipe, and the coolant return inlet is connected to the inlet of the liquid cooling source through a return pipe.

[0022] It occupies little space within the enclosed chamber; it enables continuous heat dissipation from the air within the enclosed chamber; after releasing heat, the airflow continues to flow away from the airflow heat exchanger, facilitating rapid cooling of the enclosed chamber.

[0023] Furthermore, the enclosed cabin is also equipped with an air duct, and one side wall of the shell is fixed to the side wall of the air duct, with the convection window communicating with the interior of the air duct.

[0024] By connecting the space far from the shell through the air duct, the distance between the air inlet and outlet of the heat dissipation device inside the cabin is greatly increased. As a result, the air inlet temperature of the heat dissipation device inside the cabin is closer to the temperature of the hot air inside the closed cabin, thus improving the heat dissipation efficiency.

Detailed Implementation

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] This utility model refers to Figure 1-2 .

[0030] Example 1, such as Figure 1 As shown: This utility model provides a heat dissipation device for a cabin, including a shell 1, an airflow heat exchanger 2 fixed inside the shell 1, a convection window 3 opened on one side wall of the shell 1, a convection fan 4 installed inside the convection window 3, the convection fan 4 is used to drive airflow through the convection window 3 and through the airflow heat exchanger 2; a coolant inlet port 5 and a coolant return port 6 are also fixed on the shell 1, the inlet of the airflow heat exchanger 2 is connected to the coolant inlet port 5 through a pipe, and the outlet of the airflow heat exchanger 2 is connected to the coolant return port 6 through a pipe.

[0031] Working principle: During installation, the casing 1 is fixed within the enclosed chamber. The coolant inlet 5 and coolant return 6 are connected to an external liquid cooling source 10 via pipelines. The liquid cooling source 10 can be a condensing station, liquid nitrogen station, liquid nitrogen cylinder, etc. If necessary, pumps, compressors, or other conveying equipment can be installed on the pipeline between the coolant return 6 and the liquid cooling source 10; if the liquid cooling source 10 already has conveying equipment, no additional conveying equipment is required. The airflow heat exchanger 2 can be an evaporator.

[0032] During operation, the liquid cooling medium from the liquid cooling source 10 is transported to the coolant inlet 5 through pipelines, and then enters the airflow heat exchanger 2. After absorbing heat and evaporating in the airflow heat exchanger 2, it returns to the liquid cooling source 10 through the coolant return interface 6. The liquid cooling source 10 can then recompress or discard the liquid cooling medium. Simultaneously, the convection fan 4 operates, providing kinetic energy to the air inside the sealed chamber. The hot airflow inside the sealed chamber releases heat as it passes through the airflow heat exchanger 2, converting into cold air. Subsequently, the cold air continues to move away from the airflow heat exchanger 2 and is blown into the sealed chamber, thus achieving heat dissipation and cooling of the sealed chamber.

[0033] This utility model can be installed in a closed chamber for operation. The coolant inlet 5 and coolant return 6 can be used to connect to an external liquid cooling source 10, so that no additional space is needed to install a compressor in the closed chamber, thus occupying little space. The air in the closed chamber is driven by the convection fan 4, so that the airflow passes through the convection window 3 and flows through the airflow heat exchanger 2, thereby realizing the continuous heat dissipation of the air in the closed chamber. After the airflow passes through the airflow heat exchanger 2 releases heat, it continues to flow away from the airflow heat exchanger 2, which facilitates rapid cooling of the closed chamber.

[0034] Furthermore, one side of the airflow heat exchanger 2 is attached to the inner side of one side wall of the housing 1, and the convection fan 4 is directly opposite the airflow heat exchanger 2.

[0035] Preferably, the airflow heat exchanger 2 is provided with a cuboid frame, and the edges of the frame on the same side are all located on the same plane and are attached to the inner side of one side wall of the housing 1.

[0036] To prevent some airflow from flowing directly from the gap between the airflow heat exchanger 2 and the side wall of the shell 1 to the convection window 3, it is easier to ensure that the airflow of the convection fan 4 flows evenly through the airflow heat exchanger 2, thereby improving the heat dissipation efficiency.

[0037] Furthermore, the outlet side of the convection fan 4 is directly opposite the airflow heat exchanger 2.

[0038] This facilitates increasing the kinetic energy of the airflow passing through the airflow heat exchanger 2, thereby increasing the convective heat transfer rate between the air and the airflow heat exchanger 2.

[0039] Furthermore, the convection window 3 is provided in multiple locations, and each convection window 3 is equipped with a convection fan 4.

[0040] Preferably, there are three convection windows 3 and three convection fans 4. The convection windows 3 can be arranged on the same side of the housing 1, or multiple convection windows 3 can be opened on opposite sides of the housing 1.

[0041] This facilitates increased airflow and improved heat dissipation efficiency.

[0042] Furthermore, at least one side of the housing 1 is open.

[0043] This allows air inside the sealed chamber to enter and exit the shell 1 from the open side, and then enter and exit the airflow heat exchanger 2.

[0044] Note: Air enters or exits the casing 1 from the open side, and the direction is determined by the orientation of the convection fan 4.

[0045] Furthermore, a temperature sensor 7 is also fixed on the housing 1, with the probe end of the temperature sensor 7 located outside the housing 1.

[0046] The temperature of the installation environment of this utility model is detected by the temperature sensor 7, which makes it easy to judge and control the state and flow rate of the liquid cooling medium provided by the liquid cooling source 10, and the temperature control is convenient.

[0047] Furthermore, a power supply connector 8 is also fixed on the housing 1, and the temperature sensor 7 and the convection fan 4 are electrically connected to the power supply connector 8 respectively.

[0048] Preferably, the temperature sensor 7 and the convection fan 4 are connected to the power supply connector 8 via wires.

[0049] This facilitates the supply of power to the temperature sensor 7 and the convection fan 4.

[0050] Furthermore, the bottom wall of the housing 1 is provided with extension portions 9 at both ends, the extension portions 9 protruding from both ends of the housing 1, and multiple mounting holes are provided on the extension portions 9.

[0051] The extension 9 and mounting holes facilitate the installation of the housing 1 by bolting it to a fixed structure such as the wall of the enclosed compartment, making installation convenient.

The coolant inlet 5 is connected to the outlet of the liquid cooling source 10 through an inlet pipe 11, and the coolant return 6 is connected to the inlet of the liquid cooling source 10 through a return pipe 12.

[0053] It occupies little space within the enclosed chamber; it enables continuous heat dissipation from the air within the enclosed chamber; after the airflow passes through the airflow heat exchanger 2 and releases heat, it continues to flow away from the airflow heat exchanger 2, facilitating rapid cooling of the enclosed chamber.

[0054] Furthermore, the enclosed cabin is also equipped with an air duct 13, one side wall of the shell 1 is fixed to the side wall of the air duct 13, and the convection window 3 is connected to the interior of the air duct 13.

[0055] Preferably, the duct 13 is fixed to the wall of the enclosed chamber; the duct 13 is a rectangular pipe. The outlet side of the convection fan 4 faces the airflow heat exchanger 2.

[0056] By connecting the space farther away from the shell 1 through the air duct 13, the distance between the air inlet and outlet of the heat dissipation device inside the cabin is greatly increased, so that the air inlet temperature of the heat dissipation device inside the cabin is closer to the hot air temperature inside the closed cabin, thus improving the heat dissipation efficiency.
