Description

Technical Field

[0001] The utility model relates to the technical field of energy storage, in particular to a condensation fan for an energy storage unit. Background Technique

[0002] Energy storage technology is one of the important fields in the current energy industry. It can solve the challenges of the volatility of renewable energy and sustainable power supply. Among them, the thermal management of energy storage systems is the key to ensuring the efficient operation of energy storage systems and extending their service life, which can prevent the energy storage system from overheating and ensure that it operates within an appropriate temperature range.

[0003] At present, traditional energy storage thermal management generally uses a liquid cooling method to control the temperature. Heat transfer and heat dissipation are achieved by coolant flowing through the hot spots in the energy storage system. Among them, the energy storage liquid cooling unit uses a condensation fan to bring the heat absorbed by the refrigerant to the environment to cool the refrigerant. However, regardless of the changes in the refrigeration load, the load adjustment of the compressor, or the changes in the condensation pressure, etc., the traditional condensation fan only maintains one rotation speed. This method will make the system stable at a relatively high condensation pressure value, resulting in increased energy consumption, slower startup to steady state speed, increased equipment loss, and shortened service life.

[0004] Therefore, there is an urgent need to provide a condensation fan for an energy storage unit that adjusts the rotation speed according to the condensation pressure. Content of the Utility Model

[0005] In order to overcome the disadvantages that the rotation speed of the traditional condensation fan cannot be adjusted according to the change of the condensation pressure, resulting in the liquid cooling system being stable at a relatively high condensation pressure value, increased energy consumption, slower startup to steady state speed, increased equipment loss, and shortened service life, the utility model provides a condensation fan for an energy storage unit that adjusts the rotation speed according to the condensation pressure.

[0006] To achieve the above problems, the utility model adopts the following technical solutions: A condensation fan for an energy storage unit, including a fan group, a first mounting plate is fixedly connected to the fan group, an MCU chip, a fan speed controller and a display are installed on the first mounting plate, a mounting frame is fixedly connected to the fan group, a signal transmitter and a signal receiver are arranged on the mounting frame, the signal transmitter and the signal receiver are respectively located on both sides of the fan group, a condensation box is arranged on the fan group, a pressure sensor is installed on the condensation box, a refrigeration copper pipe is connected and communicated with the condensation box, a heat sink group is arranged on the condensation box, and the refrigeration copper pipe is arranged in a serpentine shape on the heat sink group.

[0007] In addition, particularly preferably, a limiting frame is fixedly connected to the first mounting plate, a protective frame is detachably arranged on the limiting frame, and a fixing knob is arranged on the protective frame in a threaded manner.

[0008] In addition, it is particularly preferred that fixing plates are provided on both sides of the fan group, and the fixing plates are jointly clamped with a second mounting plate.

[0009] In addition, it is particularly preferred that a limiting plate is fixedly connected to the fixing plate.

[0010] In addition, it is particularly preferred that dust-proof plates are provided on both sides of the heat sink group.

[0011] In addition, it is particularly preferred that a transparent plate is embedded in the condensation box.

[0012] Compared with the prior art, the utility model has the following technical effects: 1. The device has an independent control unit and peripheral input / output components, and can output a fan speed adjustment signal that conforms to the condensation pressure according to the condensation pressure, so that the energy storage liquid cooling unit can quickly reach the condensation pressure balance point from startup, output stable refrigerating capacity, the stable value of its condensation pressure is lower, the load of the compressor is smaller, and the energy consumption is reduced.

Detailed implementation mode

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1

Among them, the MCU chip 2 and the fan speed controller 3 are control units for the fan group 5, used to receive the rotational speed and condensation pressure parameters controlled by the condensation fan, run control logic, fault alarm and external output interfaces, etc., and the display 4 is used to display various parameters and data. A mounting bracket 6 is fixedly connected to the fan group 5, a signal transmitter 601 and a signal receiver 602 are arranged on the mounting bracket 6, the signal transmitter 601 and the signal receiver 602 are respectively located on the front and rear sides of the fan group 5, and the signal transmitter 601 and the signal receiver 602 are used to collect the actual operating speed of the condensation fan. A condensation box 7 is arranged on the fan group 5, a transparent plate 16 is embedded on the condensation box 7, and the setting of the transparent plate 16 facilitates the staff to observe the internal situation of the condensation box 7. A pressure sensor 701 is installed on the condensation box 7, and the pressure sensor 701 is used to collect the condensation pressure. A refrigeration copper tube 702 is connected and communicated with the condensation box 7, a heat sink group 8 is arranged on the condensation box 7, and the refrigeration copper tube 702 is arranged in a serpentine shape on the heat sink group 8, which can increase the heat dissipation area. Dust-proof plates 15 are arranged on the front and rear sides of the heat sink group 8, and the dust-proof plates 15 are used to intercept foreign objects and dust in the air to avoid foreign objects and dust adhering to the heat sink group 8.

[0025] When the energy storage liquid cooling unit is operating, the refrigerant in a high-temperature and high-pressure gaseous state enters the condensation box 7 from the compressor. The pressure sensor 701 starts to collect the condensation pressure. According to the collected condensation pressure data, the MCU chip 2 outputs a fan group 5 speed regulation signal that conforms to the condensation pressure. The fan group 5 starts to operate to drive the surrounding air to flow, forming an air current. The air current directly contacts the refrigeration copper tube 702, thereby driving away the heat of the refrigerant in the refrigeration copper tube 702 and turning the refrigerant into a high-pressure refrigeration liquid. In this way, the energy storage liquid cooling unit can quickly reach the condensation pressure balance point from startup, output stable refrigeration capacity, and finally the stable value of the condensation pressure is lower, the compressor load is smaller, and the energy consumption is reduced.
