Description

Technical Field

[0001] This utility model relates to the field of control device technology, specifically a cold storage control device for a virtual power plant. Background Technology

[0002] In virtual power plants and various high-density power electronic equipment cabinets, the heat load generated during operation is concentrated in the top area of ​​the modules, while the bottom temperature is relatively low, resulting in severe temperature stratification inside the cabinet. Long-term temperature gradients not only affect the heat dissipation efficiency of the equipment inside the cabinet but also accelerate the aging and failure of electronic components, reducing the reliability and lifespan of the system.

[0003] Currently, common server rack cooling methods mainly rely on a single fan or a combination of multiple fans to blow cool air into the rack from fixed exhaust vents, and then exhaust hot air from top or side return vents. This unidirectional convection cannot effectively mix the air between upper and lower layers, and problems such as localized overheating and poor temperature uniformity caused by airflow resistance and dead zones remain difficult to solve. At the same time, in order to achieve a stronger cooling effect, it is necessary to increase the fan speed or the number of fans, resulting in a significant increase in energy consumption. Utility Model Content

[0004] This invention aims to solve the problems of severe internal temperature stratification, uneven heat dissipation, and high energy consumption in the existing technology of cabinets, and provides a virtual power plant cold storage control device that can intelligently regulate internal airflow and achieve uniform and efficient heat dissipation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A virtual power plant cold storage control device includes:

[0007] The main body of the cabinet has a lower air vent at its lower edge and an upper air vent at its upper edge; both the upper and lower air vents are equipped with fans.

[0008] The main body of the cabinet is equipped with an airflow disturbance component that acts on the upper and lower air vents. The airflow disturbance component includes a first baffle and a second baffle, and both the first baffle and the second baffle are hinged with an active connecting rod and an auxiliary connecting rod.

[0009] The airflow disturbance component also includes a sliding frame. A driving member is slidably mounted on the sliding frame, and the driving member has a sliding groove. The active connecting rod has a sliding part that cooperates with the sliding groove. Both the active connecting rod and the auxiliary connecting rod are hinged to the sliding frame.

[0010] Both the first baffle and the second baffle are provided with a number of flow holes and are equipped with cooling components.

[0011] As a preferred embodiment, a drive cylinder is fixed on the sliding frame, and the movable end of the drive cylinder is fixedly connected to the drive component, so that the drive component is driven to slide by the extension and retraction of the cylinder.

[0012] As another preferred embodiment, a baffle plate is provided inside the main body of the cabinet and along the airflow path between the upper and lower air vents. The baffle plate is provided with several guide vanes that can swing vertically.

[0013] Furthermore, a rotating motor is fixed on the guide plate, and the output end of the rotating motor is fixedly connected to the guide vane to precisely control the airflow direction.

[0014] Furthermore, the main body of the cabinet is also provided with a circulation chamber, and the fan is set in the circulation chamber to form an independent air duct, reducing interference with the internal space of the cabinet.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Dynamic airflow organization to eliminate temperature stratification: The opening angle of the first and second baffles can be flexibly adjusted by a drive mechanism. This breaks away from the traditional fixed air duct and can dynamically disturb and organize the airflow in the cabinet according to the actual heat load, forcibly mixing the upper and lower layers of air, effectively eliminating vertical temperature stratification and improving the uniformity of the temperature field.

[0017] 2. Precise cold storage and dissipation with high efficiency: The cooling components and flow holes are directly integrated into the baffle. This allows the device to function as both an airflow guide and a cold source for active cooling. The cooling capacity can directly act on the passing airflow, achieving the integration of "cold storage" and "dissipation," resulting in a shorter heat dissipation path and higher efficiency.

[0018] 3. Multi-mode intelligent operation, energy saving and consumption reduction: This device can achieve multiple operating modes through combined control of fan speed and baffle status (cooling / airflow). For example, when the equipment is fully loaded, a forced heat dissipation mode of upper cooling and lower high airflow can be used; when in light-load standby mode, an energy-saving mode of upper exhaust and lower cold storage can be used. This refined control strategy can minimize the energy consumption of the fan and cooling components while meeting heat dissipation requirements. Attached Figure Description

[0033] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0034] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0035] Reference Figures 1 to 5This utility model provides a cold storage control device for a virtual power plant. The core component of the device is installed inside a cabinet body 1. The upper edge of the cabinet body 1 is provided with an upper air vent 11, and the lower edge is provided with a lower air vent 12. Both the upper air vent 11 and the lower air vent 12 are equipped with fans 2. Preferably, the fans 2 can be set in an independent circulation chamber 6 to drive air to circulate inside and outside the cabinet or between the upper and lower parts of the cabinet.

[0036] The key component inside the main cabinet 1 is an airflow disturbance assembly 3. This assembly includes a first baffle 31 located at the top and a second baffle 32 located at the bottom. Both baffles are connected to a sliding frame 35 via a hinged active link 33 and an auxiliary link 34.

[0037] A drive member 36 is provided on the sliding frame 35, which can slide along its guide rail. The drive member 36 has a sliding groove 361, and one end of the active connecting rod 33 has a sliding part 331, which can slide within the sliding groove 361. When the drive member 36 moves on the sliding frame 35, the cooperation between the sliding groove 361 and the sliding part 331 pushes the active connecting rod 33 to move, which in turn drives the first baffle 31 and the second baffle 32 to rotate around their hinge point through the lever principle, thereby changing their opening and closing angle. The power source for the drive member 36 can be a drive cylinder 4, with the piston rod of the cylinder connected to the drive member 36, making control simple and reliable.

[0038] The first baffle 31 and the second baffle 32 are not solid baffles; they have multiple flow holes 311 to allow air to pass through even when the baffles are closed. More importantly, cooling components, such as thermoelectric coolers or miniature compressor cooling circulation pipes, are integrated on the surface or inside the two baffles. This allows the baffles to actively cool the air flowing through them while regulating airflow, achieving a cold storage function.

[0039] To further optimize airflow direction, a deflector plate 5 can be installed on the inner wall of the main cabinet 1, especially along the airflow path at the air vents. Multiple oscillating air guide vanes 51 are mounted on the deflector plate 5 via a rotating shaft. Each (or group of) air guide vanes 51 is connected to the output of a rotating motor 52. The motor controls the deflection angle of the air guide vanes, thereby precisely guiding the direction of hot and cold airflow and avoiding the formation of heat dissipation dead zones.

[0040] Workflow and Model Description:

[0041] This device coordinates and controls the speed of the fan 2, the action of the drive cylinder 4, and the switching of the cooling components through a central controller, and can achieve the following four typical operating modes:

[0042] Mode 1: Top cooling, bottom cooling (refer to...) Figure 2 )

[0043] Application scenarios: When the entire machine is in a normal and stable operating state, or when there is a requirement for uniform temperature throughout the cabinet.

[0044] Control logic: The controller drives cylinder 4, causing both the first baffle 31 and the second baffle 32 to be in a half-open or specific angle state, and simultaneously activating the cooling components of both. The upper and lower fans 2 operate at a medium or matched speed.

[0045] Airflow effect: Cool air is generated and evenly delivered from both the upper and lower layers, forming a stable and uniform cooling field within the cabinet and maintaining overall temperature balance.

[0046] Mode 2: Top cooling, bottom high airflow (see reference) Figure 4 )

[0047] Application scenario: When the equipment is operating at full load, the heat at the top of the cabinet increases rapidly, requiring forced heat dissipation for areas at the bottom that may accumulate heat.

[0048] Control logic: The controller drives cylinder 4 to bring the first baffle 31 to a small opening or closed state and activate the cooling component on it; at the same time, it brings the second baffle 32 to its maximum opening. The upper fan 2 operates at low or medium speed, and the lower fan 2 operates at high speed.

[0049] Airflow effect: The cool air generated at the top is quickly drawn in by the large airflow below and sent into the space below the cabinet, forcing convection, quickly neutralizing and expelling the heat accumulated at the top.

[0050] Mode 3: High airflow at the top, cooling at the bottom (see reference) Figure 5 )

[0051] Application scenario: When the device is under light load or in standby mode, it is designed to save energy and maintain low temperatures in critical areas.

[0052] Control logic: The controller drives cylinder 4 to the maximum opening of the first baffle 31, shutting off its cooling component; simultaneously, it shuts off the second baffle 32 to the closed or slightly open state, turning on its cooling component. The upper fan 2 operates at high speed, while the lower fan 2 operates at low speed or stops.

[0053] Airflow effect: The upper fan quickly extracts a small amount of hot air from the cabinet, while the lower baffle performs deep cooling to maintain a low-temperature environment for key components at the bottom, achieving a cooling effect of "using the best steel where it is needed" with minimal energy consumption.

[0054] Mode 4: High airflow at the top, high airflow at the bottom (see reference) Figure 6 )

[0055] Application scenario: Short-term emergency cooling when system load suddenly increases or external ambient temperature rises sharply.

[0056] Control logic: The controller shuts down all refrigeration components (without cold storage intervention), while simultaneously driving cylinder 4 to bring both the first baffle 31 and the second baffle 32 to their maximum opening. Both upper and lower fans 2 operate at their highest speed.

[0057] Airflow effect: Creates the strongest air convection within the cabinet, replacing internal air with maximum airflow to achieve the fastest cooling response.

[0058] In summary, this utility model, through its innovative adjustable cold storage baffle structure combined with a multi-mode intelligent control algorithm, successfully solves the problem of heat dissipation in traditional cabinets, providing a strong guarantee for the stable, reliable, and energy-efficient operation of high-density electronic equipment.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
