Description

Technical Field

[0001] This utility model belongs to the field of cabin heat dissipation and ventilation technology, specifically relating to a liquid cooling device that can realize cabin ventilation and equipment heat dissipation. Background Technology

[0002] As a mobile, integrated operational unit, modular shelters are widely used in field operations, emergency rescue, and mobile command scenarios. They typically integrate multiple sets of electronic equipment and power devices, placing stringent demands on heat dissipation and ventilation. However, the working environment of modular shelters often presents the following challenges:

[0003] Coolant loss in arid regions: In arid and low-rainfall areas, micro-leakage or evaporation in a closed-loop system can lead to a continuous decrease in coolant volume, requiring frequent manual water replenishment. This not only increases maintenance costs but may also affect heat dissipation efficiency and threaten the safety of power devices if water is not replenished in a timely manner.

[0004] Dust and low-temperature frost affect heat exchange efficiency: When the mobile shelter operates in a dusty outdoor environment, the heat exchanger is easily blocked by sand and dust, resulting in a reduction in heat exchange area; in low-temperature environments, the surface of the heat exchanger is prone to frost, which further hinders heat exchange and reduces heat dissipation capacity.

[0005] Compact, lightweight, and electromagnetic compatibility requirements: The internal space of the container is limited, and the liquid cooling equipment needs to be small in size and light in weight while meeting performance requirements; in addition, the internal electronic equipment is dense, and the electrical components of the liquid cooling system need to avoid generating electromagnetic interference to the outside world, while resisting external interference to ensure the normal operation of the equipment.

[0006] Existing liquid cooling equipment is insufficient to address the aforementioned issues simultaneously. Therefore, there is an urgent need for a dedicated liquid cooling device for container cabins that can automatically replenish liquid, resist dust and frost, be compact and interference-resistant, and also provide heat dissipation and ventilation functions. Utility Model Content

[0007] The purpose of this utility model is to provide a liquid cooling device that can realize ventilation and equipment heat dissipation in the container, so as to solve the problem mentioned in the background art that the existing equipment is difficult to solve simultaneously with automatic liquid replenishment, dust and frost prevention, compact anti-interference and heat dissipation and ventilation functions.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a liquid cooling device for realizing ventilation and equipment heat dissipation in a container, comprising a fixed plate and a return liquid temperature transmitter, a supply liquid temperature transmitter, and an ambient temperature transmitter disposed on one side of the fixed plate. A plate-fin heat exchanger is installed on one side of the fixed plate, and multiple fans are installed inside the plate-fin heat exchanger. An ambient temperature transmitter is disposed on the air inlet surface of the plate-fin heat exchanger. An expansion tank is installed on one side of the fixed plate, and an air supply valve is installed on the top of the expansion tank. An exhaust valve and a pump pre-pressure transmitter are respectively installed on one side of the expansion tank. A liquid supply pipeline is disposed on one side of the expansion tank, and a liquid supply pressure transmitter is installed on the liquid supply pipeline. A water pump is disposed below the return liquid temperature transmitter.

[0009] In a further embodiment, a liquid supply port and a liquid return port are respectively provided on one side of the fixing plate, the liquid supply temperature transmitter is installed on the liquid supply port, and the liquid return temperature transmitter is installed on the liquid return port.

[0010] In a further embodiment, a level transmitter is installed on one inner wall of the expansion tank, and an injection pipe is installed on the lower outer wall of the expansion tank, with an automatic water replenishment valve installed inside the injection pipe.

[0011] In a further embodiment, a removable dust filter is installed on the air inlet side of the plate-fin heat exchanger, and the surface of the plate-fin heat exchanger is coated with a low-temperature anti-frost coating.

[0012] In a further embodiment, a driver for driving a water pump is provided on one side of the expansion tank.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This liquid cooling device, which enables ventilation and heat dissipation of the container, integrates a liquid level transmitter and an automatic water replenishment valve in the expansion tank. It can monitor the coolant level in real time and automatically start water replenishment when the level is lower than the preset threshold, reducing the frequency of manual maintenance, solving the pain point of rapid coolant evaporation and frequent water replenishment in arid areas, and improving the reliability of the equipment when it is unattended.

[0015] The plate-fin heat exchanger is equipped with a removable dust filter on the air inlet side to prevent sand and dust from entering the core and avoid clogging; the low-temperature anti-frost coating (such as PTFE modified coating) sprayed on the surface reduces the adhesion of frost layer, and together with the airflow of the fan, it can reduce the impact of frost on heat exchange and ensure heat exchange efficiency in dusty and low-temperature environments.

[0016] The core components such as the return liquid temperature transmitter, supply liquid temperature transmitter, plate-fin heat exchanger, and expansion tank are integrated and installed by fixing plate. Combined with the modular design of plate-fin heat exchanger and fan, the overall size and weight of the equipment are greatly reduced, which is suitable for the needs of small space in the container.

[0017] The plate-fin heat exchanger, in conjunction with the fan, not only dissipates the coolant but also drives the exchange of air inside and outside the container, combining equipment cooling and container ventilation functions. This reduces the need for additional ventilation equipment in the container, improves system integration, and enables container ventilation and equipment cooling. The liquid cooling device is compact, has strong anti-electromagnetic interference capabilities, can stably adapt to harsh environments, and improves the operational reliability of container equipment.

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0028] This utility model provides, for example Figure 1-6 The liquid cooling device shown is capable of achieving ventilation and equipment heat dissipation in a container cabin. It includes a fixed plate 1 and a return liquid temperature transmitter 2, a supply liquid temperature transmitter 3, and an ambient temperature transmitter 4, all mounted on one side of the fixed plate 1. A plate-fin heat exchanger 5 is installed on one side of the fixed plate 1. The plate-fin heat exchanger 5 uses an aluminum plate-fin structure (high heat exchange efficiency and light weight). Multiple fans 6 are installed inside the plate-fin heat exchanger 5. The fans 6 and the plate-fin heat exchanger 5 form a modular heat dissipation unit, embedded in mounting holes opened in the cabin wall, reducing space occupation and facilitating air circulation between the inside and outside of the cabin. The air inlet surface of the plate-fin heat exchanger 5 is provided with... An ambient temperature transmitter 4 is used to monitor the ambient temperature. The air inlet side of the plate-fin heat exchanger 5 is connected to a removable dust filter via a snap-fit ​​connection. The filter has a double-layer structure: the outer layer is a stainless steel mesh (to block large particles of sand and dust), and the inner layer is an activated carbon fiber layer (to adsorb fine dust and moisture). It can be disassembled for cleaning or replacement periodically to prevent the core of the plate-fin heat exchanger 5 from clogging. The fin surface of the plate-fin heat exchanger 5 is coated with a 0.05-0.1mm thick polytetrafluoroethylene anti-frost coating. Its low surface energy characteristics reduce frost adhesion. In conjunction with the periodic reverse rotation of the fan 6, light frost can be removed to ensure heat exchange efficiency at low temperatures.

[0029] An expansion tank 7 is installed on one side of the fixed plate 1. An air supply valve 9 is installed on the top of the expansion tank 7 to supply nitrogen and maintain the initial pressure inside the expansion tank 7. An exhaust valve 8 and a pressure transmitter 10 before the pump are installed on one side of the expansion tank 7. The exhaust valve 8 can discharge air from the expansion tank 7 to avoid air blockage. A liquid level transmitter 16 (using an immersion static pressure sensor with a range of 0-500mm) is connected to the inner wall of one side of the expansion tank 7 by a thread to monitor the liquid level. A liquid injection pipe is welded to the outer wall of the lower half of the expansion tank 7. An automatic water supply valve 17 is installed inside the pipe. The other end of the liquid injection pipe is connected to the coolant storage tank in the container through a low-temperature resistant hose. When the liquid level transmitter 16 detects that the liquid level is lower than the set value, the automatic water supply valve 17 opens to supply water and closes when the liquid level reaches the set value.

[0030] The fixed plate 1 is also equipped with a liquid supply port 13 and a liquid return port 14. A liquid supply temperature transmitter 3 (PT100 type, accuracy ±0.5℃) is installed on the liquid supply port 13, and a liquid return temperature transmitter 2 is installed on the liquid return port 14 to monitor the liquid supply and liquid return temperatures respectively. A water pump 12 (DC speed-regulating centrifugal pump, flow rate 5-20L / min, head 5-15m) is connected to the bottom of the liquid return port 14 via a flange. A driver 15 (using PWM speed regulation, input voltage 24VDC) is set on one side of the pump 12, which can automatically adjust the speed of the water pump 12 according to the temperature difference between the liquid supply temperature transmitter 3 and the liquid return temperature transmitter 2 to optimize the flow rate. A liquid supply pressure transmitter 11 (range 0-1MPa, accuracy ±0.5%FS) is installed on the liquid supply pipeline at the outlet of the water pump 12 to monitor the outlet pressure. When the pressure exceeds the set value, the driver 15 automatically reduces the speed to avoid overpressure in the pipeline.

[0031] In addition, the connecting cables of the fan 6, water pump 12, driver 15 and each transmitter are all covered with copper mesh anti-wave sleeves and connected to the fixed plate 1 (grounded) to form electromagnetic shielding and reduce electromagnetic interference.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0034] Working principle:

[0035] This liquid cooling device enables ventilation and equipment heat dissipation in the container. The water pump 12 is started under the control of the driver 15, driving the coolant from the supply port 13 into the power equipment in the container. After absorbing the heat generated by the equipment operation, the coolant returns to the liquid cooling device through the return port 14. The return temperature transmitter 2 monitors the temperature of the coolant after heat absorption in real time, and the supply temperature transmitter 3 monitors the supply temperature before entering the equipment. The two work together to reflect the heat dissipation effect. The high-temperature coolant after heat absorption enters the plate-fin heat exchanger 5. At this time, the fan 6 starts, driving the ambient air to flow through the plate-fin heat exchanger 5. The heat exchange between the coolant and the air is achieved through the plate-fin structure (at the same time, the air flow drives the air circulation inside and outside the container, realizing the ventilation of the container).

[0036] Ambient temperature transmitter 4 monitors the inlet air temperature, providing a basis for heat dissipation efficiency control. The cooled coolant flows into expansion tank 7. The stainless steel expansion joint in expansion tank 7 expands and contracts according to system pressure changes (expands when the pressure is too high and contracts when the pressure is too low), stabilizing the system pressure. Pump pressure transmitter 10 monitors the outlet pressure of expansion tank 7 to ensure stable inlet pressure of water pump 12. Liquid supply pressure transmitter 11 in the liquid supply pipeline monitors the outlet pressure of water pump 12 in real time to avoid damage to power equipment due to excessive pressure. When liquid level transmitter 16 in expansion tank 7 detects that the coolant level is lower than the preset threshold, automatic water replenishment valve 17 opens, replenishing water from the coolant source stored in the container through the liquid injection pipe. It closes after the liquid level reaches the target, realizing adaptive liquid replenishment. The removable dust filter on the air inlet side of plate-fin heat exchanger 5 blocks sand and dust, and the surface anti-frost coating reduces low-temperature frost formation, ensuring continuous and efficient heat exchange. All electrical components are protected by anti-wave nets and grounding to avoid electromagnetic interference and ensure stable system operation.
