Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, specifically to a water-to-water heat exchange cooling device. Background Technology

[0002] The energy storage industry has become an important part of my country's strategic emerging industries. Currently, the development trend in the energy storage field is towards large-scale and ultra-large-scale storage, which in turn increases the heat dissipation of the supporting electrical equipment, thus posing higher challenges to heat dissipation requirements. At the same time, the high volume ratio standards for energy storage equipment also impose stringent requirements on the external dimensions of the heat dissipation equipment.

[0003] Currently available water-to-water heat exchange cooling equipment is bulky, requires ample installation space, and cannot be placed inside containers to be integrated with energy storage modules or other electrical equipment. It also requires an additional heat exchange stage, leading to energy loss and slow cooling speed. While plate heat exchangers offer high heat exchange efficiency, they are susceptible to scaling and clogging due to water quality, resulting in higher maintenance costs.

[0004] Therefore, it can be seen that existing heat dissipation equipment has disadvantages such as large size and low heat dissipation, that is, there is a problem of balancing size and heat dissipation efficiency. Utility Model Content

[0005] Therefore, this utility model provides a water-to-water heat exchange cooling device, which is generally used for cooling hydrogen energy storage electrical equipment. The water-to-water heat exchange cooling device provided by this utility model takes into account both the high integration of the heat exchange device and its extremely small size, so as to solve the problem that the current heat dissipation devices mentioned in the background art cannot meet the requirements of high heat dissipation and small size.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The third end of the first electric three-way valve is connected to a first branch pipe. The end of the first branch pipe away from the first electric three-way valve is connected to the pipeline connecting the cold source water outlet and the plate heat exchanger.

[0011] The system includes a first butterfly valve installed on the pipeline at the front end of the water pump, a one-way valve installed on the pipeline at the rear end, and a second butterfly valve connected to the rear end of the one-way valve.

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] like Figure 1-4 As shown, this embodiment provides a water-to-water heat exchange cooling device, including a primary cooling side, a secondary cooling side, and a plate heat exchanger 1. The primary cooling side is located on the right side of the plate heat exchanger 1, and the secondary cooling side is located on the left side of the plate heat exchanger 1. The primary cooling side is connected to an external cold source water, and the secondary cooling side is connected to the load heat equipment. The primary cooling side includes a cold source water inlet 11 and a cold source water outlet 12, and the secondary cooling side includes a heat source water inlet 13, a heat source water outlet 14, and a water pump 2. The plate heat exchanger 1 includes a cold medium interface, a cold medium outlet, a hot medium interface, and a hot medium outlet located on the same side, and is connected to the primary cooling side and the secondary cooling side through stainless steel pipes. The cold source water flowing through the primary cooling side and the hot source water flowing through the secondary cooling side exchange heat through the plate heat exchanger 1 to achieve the effect of heat dissipation and cooling of the equipment.

[0029] Specifically: the cold water inlet 11 on the cooling side is located on the lower right side of the plate heat exchanger 1 and is connected to the cold medium interface of the plate heat exchanger 1 through a stainless steel pipe; the cold water outlet 12 is located above the cold water inlet 11 and is connected to the cold medium outlet of the plate heat exchanger 1 through a stainless steel pipe; the water pump 2 on the secondary cooling side is located above the plate heat exchanger 1; the heat water inlet 13 is located on the left side of the water pump 2 and is connected to the water pump 2 through a stainless steel pipe; the water pump 2 is connected to the heat medium interface of the plate heat exchanger 1 through a stainless steel pipe; and the heat water outlet 14 is located below the heat water inlet 13 and is connected to the heat medium outlet of the plate heat exchanger 1 through a stainless steel pipe.

[0030] The heat source water on the secondary cooling side is powered by water pump 2 and transported to the plate heat exchanger 1 through stainless steel pipes. At the same time, the cold source water on the primary cooling side flows into the plate heat exchanger 1 through other stainless steel pipes and exchanges heat with the heat source water in the plate heat exchanger 1. After the cold source water is heated by heat exchange, it transfers heat out through the cold source water outlet 12. The cooling water after heat exchange flows into the electrical equipment that needs to be cooled through the heat source water outlet 14, thus completing the cooling of the load heat equipment.

[0031] A first electric three-way valve 15 is installed on the pipeline connecting the cold source water inlet 11 and the plate heat exchanger 1. The third end of the first electric three-way valve 15 is connected to a first branch pipe 18. The end of the first branch pipe 18 away from the first electric three-way valve 15 is connected to the pipeline connecting the cold source water outlet 12 and the plate heat exchanger 1. In this way, a controllable branch is added to the primary cooling side. The first electric three-way valve 15 can change the flow direction of the medium as needed, and thus can adjust the flow rate of the cold source water as needed to ensure heat exchange efficiency.

[0032] A first butterfly valve 4 is installed on the inlet side of the water pump 2, which can be quickly opened and closed and can regulate the water flow rate and pressure. A one-way valve 5 is installed on the outlet side pipeline of the water pump 2 to prevent backflow of the medium and protect the water pump 2 from reverse impact. A second butterfly valve 16 is connected to the rear end of the one-way valve 5 (referring to the side or end away from the water pump 2), which forms a double isolation with the first butterfly valve 4, and provides redundant cut-off when the one-way valve 5 fails, thereby enhancing system safety.

[0033] The secondary cooling side is equipped with two water pumps 2. The inlets of the two water pumps 2 are connected to the front end of the first butterfly valve 4 through stainless steel pipes ("front" refers to the direction in which the water flows, and "front end" here refers to the end of the first butterfly valve 4 away from the water pump 2). The outlets of the two water pumps 2 are connected to the rear end of the second butterfly valve 16 through stainless steel pipes ("rear" refers to the direction in which the water flows, and "rear end" here refers to the end of the second butterfly valve 16 away from the water pump 2). By adopting a one-in-one-out design, when one water pump stops, the control system collects the fault signal and automatically switches to the standby water pump to ensure that the equipment can operate normally.

[0034] An expansion tank 3 is installed next to the water pump 2. The expansion tank 3 is connected to the heat source water inlet 13 through a stainless steel pipe. The expansion tank 3 has the functions of pressure stabilization and buffering. It can buffer the mechanical impact when the water pump starts and stops, prevent water hammer effect from impacting the pipes and equipment, and reduce the number of water pump starts and stops by stabilizing the pressure, thereby achieving energy saving.

[0035] A second electric three-way valve 8 is provided on the pipeline connecting the water pump 2 and the plate heat exchanger 1. The third end of the second electric three-way valve 8 is connected to a second branch pipe 10. The end of the second branch pipe 10 away from the second electric three-way valve 8 is connected to the pipeline connecting the plate heat exchanger 1 and the heat source water outlet 14. The electric three-way valve 8 can also change the flow direction of the medium as needed, thereby adjusting the flow rate of the heat source water as needed to ensure heat exchange efficiency.

[0036] A filter 9, a heater 6, and a flow sensor 17 are sequentially installed on the pipeline connecting the plate heat exchanger 1 and the heat source water outlet 14. The cooling water, after heat exchange in the plate heat exchanger 1, is filtered by the filter 9 to remove residual solid impurities, preventing blockage of the heat exchanger pipes or wear on pumps and other equipment, thus maintaining efficient system operation and extending equipment lifespan. The filtered cooling water is then heated by the heater 6 and flows through the heat source water outlet 14 into the electrical equipment requiring cooling to meet usage requirements, avoiding the risk of corrosion or freezing due to excessively low temperatures, and ensuring system safety and circulation stability. Finally, the flow sensor 17 at the heat source water outlet 14 feeds flow data back to the control system, dynamically adjusting pump speed or valve opening to avoid energy waste caused by excessive circulation. Abnormal flow will trigger an alarm and activate an emergency shutdown to prevent equipment damage or safety accidents.

[0037] An automatic butterfly valve 7 is installed on the second branch pipe 10. The automatic butterfly valve 7 is located below the second electric three-way valve 8. The automatic butterfly valve 7 is remotely controlled by an electric actuator, which can accurately adjust the flow of the branch pipe and avoid sudden flow changes caused by direct switching of the second electric three-way valve 8. The slow opening and slow closing function of the automatic butterfly valve 7 (such as fast closing followed by slow closing) can effectively eliminate the water hammer effect and protect the second electric three-way valve 8 and downstream equipment from pressure shock. When the second electric three-way valve 8 fails, the automatic butterfly valve 7 can independently cut off the branch pipe to prevent backflow or leakage of the medium and improve system safety.

[0038] Butterfly valves are installed at the cold water inlet 11, cold water outlet 12, hot water inlet 13, and hot water outlet 14 to limit the flow rate, regulate the system pressure, and prevent reverse flow of the medium. The flow area can also be adjusted by rotating the butterfly plate to control the flow rate of cold / hot water and achieve precise distribution of heat exchange load. At the same time, it is also convenient to isolate the pipeline during equipment maintenance or replacement.

[0039] The control system of this equipment is located on the top of the equipment and is controlled by an electrical box. It has manual and automatic modes. In manual mode, the main circulation pump, three-way valve, heater, and make-up water pump are started / stopped via the operation panel. Manual mode is generally used during system maintenance and debugging. In automatic mode, the system automatically starts after receiving a remote start command and monitors the system's operating status and detects system faults according to the set parameters. The PLC automatically adjusts the cooling water temperature and system pressure, and promptly displays any deviations in system parameters. When parameters are severely out of control and may affect the safe operation of the cooled components, a fault indicator light illuminates, and a fault signal is automatically issued. The main circulation pump, electric heater, etc., are automatically controlled by the PLC according to the actual working conditions.

[0040] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
