Description

Technical Field

[0001] This utility model relates to the field of liquid cooling unit technology, specifically a liquid cooling unit with cold storage function. Background Technology

[0002] With the booming development of the energy storage industry, the application of electrochemical energy storage is gradually increasing. Temperature control equipment is a crucial component of electrochemical energy storage systems, its main function being to prevent fires caused by battery overheating and to extend battery life. Utilizing heat transfer and cooling principles, temperature control equipment combines multiple heat exchange devices, heat transfer media, and control elements to ensure the energy storage system maintains a constant temperature for the battery and its surrounding environment, achieving cooling. In electrochemical energy storage systems, problems such as battery heat generation and uneven temperature distribution are prone to occur. This not only affects battery performance but may also lead to safety issues. Temperature control equipment plays a critical role in these situations, precisely regulating the temperature of the electrochemical energy storage battery to ensure the system operates at its optimal state, thereby improving battery safety and lifespan.

[0003] A cryogenic storage constant-temperature liquid refrigeration unit, authorized by announcement number CN212667701U, includes a refrigeration system, a cooling system, and a constant-temperature cryogenic storage tank. The refrigeration system includes a compressor, a condenser, a water-cooled evaporator, and a gas-liquid separator forming a circulation loop. The cooling system includes a liquid storage tank, a water-cooled heat exchanger, and an in-flight delivery system forming a circulation loop. The water-cooled evaporator and the water-cooled heat exchanger are designed as an integrated unit, arranged alternately in the constant-temperature cryogenic storage tank filled with cryogenic storage liquid. This utility model has a compact and reasonable structure, is easy to operate, and releases a large amount of excess cooling capacity during the refrigeration process. After the excess cooling capacity is absorbed by the cryogenic storage liquid, the cooling capacity required by the aircraft is input to the aircraft system through the coolant, eliminating cooling capacity waste. This achieves energy saving, high efficiency, and precise temperature control, meeting the needs of liquid cooling for aircraft support, ensuring stable and controllable liquid cooling temperature, saving energy consumption, and offering high flexibility and stability.

[0004] As shown in the above equipment, while existing liquid-cooled chiller units with cold storage function maintain stable and controllable liquid cooling temperature, save energy consumption, offer high flexibility, and are highly stable, they generate a large amount of heat during operation. This heat needs to be dissipated through a heat dissipation mechanism to maintain the unit's normal operating temperature. Without a heat dissipation mechanism, the heat cannot be effectively dissipated, leading to an increase in the internal temperature of the unit, affecting its performance and lifespan.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] See Figures 1-7 This utility model provides the following two technical solutions:

[0029] First implementation: A liquid-cooled chiller unit with cold storage function, including a chassis 1, and further comprising:

[0030] Heat dissipation mechanism 5, which is installed on the outer wall of chassis 1, is used for heat dissipation of the liquid cooling unit inside chassis 1;

[0031] The silent protective cover mechanism 4 is installed on the outer wall of the chassis 1 and is used for external protection and noise reduction of the internal liquid cooling unit of the chassis 1.

[0032] A compressor 6 is fixedly installed on the inner wall of the casing 1. The output end of the compressor 6 is connected to the input end of the condenser 7 through a connecting pipe. The output end of the condenser 7 is connected to a cold water storage tank 9 through a connecting pipe, and a throttling valve 8 is installed between the two connecting pipes. The cold water storage tank 9 has an evaporator coil, which plays a role in heat exchange. The other side of the cold water storage tank 9 is connected to the compressor 6 through a connecting pipe, forming a circulation path on the air conditioning side. The other heat exchange side of the cold water storage tank 9 is also connected to the input end of a three-way valve 10 through a connecting pipe. One of the output ends of the three-way valve 10 is connected to the input end of a water pump 11 through a connecting pipe. The output end of the water pump 11 is equipped with a battery pack 12, which is then cooled by the cold water storage tank 9.

[0033] In practical applications, after the equipment is started, if cooling is required, the high-temperature and high-pressure gas can be discharged through the operation of the compressor 6. Then, the high-temperature and high-pressure gas is liquefied through the condenser 7, and then the high-pressure liquid is throttled and depressurized through the throttling valve 8. After depressurization, it evaporates through the evaporator coil in the cold storage tank 9 and returns to the compressor 6 through a pipe connected to the compressor 6 at one end. The evaporator coil in the tank exchanges heat with the liquid in the tank, and the tank realizes the cold storage function. If cooling is required, the high-temperature water from the battery is supplied to the battery through the pipe connected to the battery pack at one end of the cold storage tank 9. The other part passes through the proportional three-way valve 10 and the water pump 11.

[0034] In a preferred embodiment, a filter ventilation plate 2 is fixedly connected to the outer wall of the chassis 1 for filtering the flowing air, and a base 3 is fixedly installed on the outer wall of the chassis 1.

[0035] The heat dissipation mechanism 5 includes a transmission beam 51, which is located on the outside of the chassis 1. At least one heat dissipation box 52 is fixedly installed on the outer wall of the transmission beam 51. The heat dissipation box 52 is fixedly installed on the outer wall of the chassis 1. A filter assembly 54 is provided on the inner wall of the heat dissipation box 52 for filtering dust and impurities in the air. A drive assembly A53 is fixedly installed on the top of the transmission beam 51 for cooperating with the transmission beam 51 to provide kinetic energy to the cooling fan 56 inside the heat dissipation box 52. A transmission seat 55 is fixedly connected to the output end of the drive assembly A53 for transmitting kinetic energy. The transmission seat 55 is used for transmission connection with the cooling fan 56 to exhaust air and dissipate heat from the chassis 1.

[0036] The filter assembly 54 includes a mounting box 541, which is located on the inner wall of the heat sink 52 away from the chassis 1. The outer wall of the mounting box 541 has multiple ventilation slots 542. A filter plate 543 is fixedly connected inside the mounting box 541. An activated carbon layer 544 is provided on one side of the filter plate 543, and a filter cotton 545 is provided on the other side of the activated carbon layer 544.

[0037] This liquid-cooled unit with cold storage function is equipped with a heat dissipation mechanism 5, which can quickly dissipate the heat generated by the liquid-cooled unit, maintain the normal operating temperature of the unit, and thus improve the heat dissipation efficiency of the entire system. The filter component 54 can prevent dust, hair and other impurities from entering the heat dissipation mechanism 5, thereby reducing the corrosion and wear of impurities on the internal structure of the casing 1, while keeping the heat sink clean, thus extending the service life of the equipment and improving the heat dissipation efficiency.

[0038] The second embodiment differs from the first embodiment in that the silent protective cover mechanism 4 includes a connecting frame 41, the inner wall of the connecting frame 41 is provided with a transmission component 42, the connecting frame 41 is connected to a crank rocker A43 through the transmission component 42, one end of the crank rocker A43 is slidably connected to a movable slide 45, the outer wall of the movable slide 45 is fixedly connected to a connecting slide plate 46, the top of the connecting slide plate 46 is provided with a silent protective cover body 44, and the transmission component 42 adjusts the coverage area of ​​the silent protective cover body 44 by driving the crank rocker A43.

[0039] The transmission assembly 42 includes a grooved plate 421, which is fixedly installed on the inner wall of the connecting frame 41. A bidirectional lead screw 422 is fixedly installed on the inner wall of the grooved plate 421. A drive motor is provided at one end of the bidirectional lead screw 422. Two movable hinge seats 423 are threadedly connected to the outer wall of the bidirectional lead screw 422. A transmission shaft 424 is fixedly connected to one end of the grooved plate 421. The transmission shaft 424 is used to connect the drive motor for kinetic energy transmission.

[0040] The liquid-cooled unit with cold storage function is equipped with a silent protective cover mechanism 4. The silent protective cover can protect the liquid-cooled unit from the influence of the external environment, such as rain, moisture and frost, and avoid damage to the unit and cooling fan. At the same time, the silent protective cover is usually made of sound insulation material, which can effectively absorb and isolate the noise generated by the compressor 6, reducing the impact of equipment operation on the work and life of surrounding residents.

[0041] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0042] When the equipment generates heat and requires ventilation, the drive assembly A53 is activated. Drive assembly A53, via transmission seat 55, drives the cooling fan 56, drawing cool air through the ventilation slot 542 on the outer wall of the mounting box 541. The air then undergoes a first-level filtration through the filter plate 543 inside the mounting box 541. After this first-level filtration, it enters the activated carbon layer 544 for secondary adsorption filtration. After this secondary adsorption filtration, the air, containing dust, undergoes a third-level filtration through filter cotton 545. After this third-level filtration, it undergoes a final filtration through the filter plate 543. This four-level filtration process removes impurities and dust. The clean air, after four filtrations, is then delivered into the chassis 1 via the ventilation slot 542. The heat carried inside the chassis 1... The air is discharged through the filter ventilation plate 2. When the equipment generates noise, the drive motor operates, which drives the bidirectional lead screw 422 to rotate via the transmission shaft 424. This causes the movable hinge seat 423 to move on the outer wall of the bidirectional lead screw 422. The movement of the movable hinge seat 423 causes the crank rocker A43 hinged to its outer wall to rotate. Through the transmission rotation of multiple crank rockers A43, a telescopic component composed of continuous X-shaped cross links is formed, which drives the movable slide 45 hinged at one end to slide on the outer wall of the chassis 1. This causes the connecting slide plate 46 to move and the soundproof protective cover body 44 to gradually extend. When the connecting slide plate 46 moves and presses against the inner wall of the base 3, the soundproof protective cover body 44 is fully extended. At this time, the soundproof protective cover body 44 can block and absorb the noise generated by the equipment unit.
