Description

Technical Field

[0001] This utility model relates to the technical field of high-voltage solid-state electric thermal energy storage equipment, specifically a high-voltage solid-state electric thermal energy storage equipment with heat exchanger protection measures. Background Technology

[0002] The heat exchanger is an important component of high-voltage solid-state electric thermal energy storage equipment. Its main function is to effectively transfer the thermal energy stored in the thermal energy storage body to the medium that needs to be heated (such as water or air).

[0003] In existing technologies, under normal conditions, the water in the heat exchanger of high-voltage solid-state electric thermal energy storage equipment is in a circulating state, which can cool the heat exchanger tubes and prevent them from overheating. However, when there is a power outage, the water in the heat exchanger does not circulate and cannot cool the heat exchanger tube walls. At this time, if the heat from the high-temperature thermal storage body in the furnace radiates to the heat exchanger tubes, it may cause the heat exchanger tube walls to overheat and malfunction. Therefore, we provide a high-voltage solid-state electric thermal energy storage equipment with protective measures for the heat exchanger. Utility Model Content

[0004] The purpose of this invention is to provide a high-voltage solid-state electric thermal energy storage device with heat exchanger protection measures to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage solid-state electric thermal energy storage device housing, a support frame is provided at the bottom of the housing, a heat insulation plate is provided on one side of the bottom of the support frame, a heat exchanger is provided in the middle of the heat insulation plate, the heat insulation plate is provided on both sides and the top of the heat exchanger, a circulating water inlet pipe is provided at the front end of the heat exchanger, one end of the circulating water inlet pipe extends out of the housing of the high-voltage solid-state electric thermal energy storage device, and an inlet pipe is provided at the top of the extended end of the circulating water inlet pipe.

[0006] Preferably, the top of the support frame is provided with heat storage bricks, which enable the high-voltage solid-state electric thermal energy storage device to store energy and heat.

[0007] Preferably, a fan is provided on one side of the bottom of the support frame, and ventilation openings are provided in the middle of both sides of the heat exchanger on the heat insulation plate. The air outlet of the fan is aligned with the ventilation opening, and the fan can blow hot air into the closed cover formed by the heat insulation plate.

[0008] Preferably, the front end of the heat exchanger is provided with a circulating water inlet pipe and a circulating water outlet pipe, which are connected to a circulating water tank to keep the water in the heat exchanger in a circulating state.

[0009] Preferably, the top of the circulating water inlet pipe is provided with an inlet pipe, which is connected to a tap water pipe. When the equipment is powered off, the cooling water can enter the heat exchanger through the inlet pipe and the circulating water inlet pipe.

[0010] Preferably, the heat insulation protective plate has sliding grooves on both sides, and a sealing plate is provided in the sliding groove. The sealing plate can seal the ventilation opening and prevent heat flow from entering the protective cover formed by the heat insulation protective plate.

[0011] Preferably, a connecting rod is provided at the middle of the front end of the sealing plate, and a telescopic rod is provided in the telescopic groove in the middle of the connecting rod. The front end of the telescopic rod and the telescopic groove are both provided with threads. The front end of the telescopic rod extends out of the housing of the high-voltage solid electric thermal storage device and is connected to the pull rod. Pulling the pull rod can make the telescopic rod extend out of the telescopic groove, and the front end of the telescopic rod and the connecting rod are connected by threads when rotated.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the event of a power outage, this utility model proposes a method where pulling a lever causes the telescopic rod to extend from the telescopic groove. Then, by screwing the lever, the telescopic rod is connected to the connecting rod via a threaded connection, extending the length of the connecting rod. Pushing the lever then causes the connecting rod to move the sealing plate, sliding the heat insulation plate in the sliding groove and sealing the ventilation openings on both sides of the heat insulation plate. This prevents heat from entering the protective cover formed by the heat insulation plate through the ventilation openings, which could cause the heat exchanger tube walls to overheat and damage the heat exchanger. Simultaneously, tap water replaces the hot water in the heat exchanger through the inlet pipe and the circulating water inlet pipe. The hot water returns to the circulating water tank through the circulating water outlet pipe. Cooling water enters the heat exchanger's casing to further cool the heat exchanger tube walls and prevent overheating. Attached Figure Description

The air outlet of the fan 10 is aligned with the ventilation opening 9, and the fan 10 can blow hot air into the closed cover formed by the heat insulation plate 4; a circulating water inlet pipe 6 and a circulating water outlet pipe 7 are installed at the front end of the heat exchanger 5, and the circulating water... The circulating water inlet pipe 6 and the circulating water outlet pipe 7 are both connected to the circulating water tank, so that the water in the heat exchanger 5 is in a circulating state. The top of the circulating water inlet pipe 6 is provided with an inlet pipe 8, which is connected to the tap water pipe. When the equipment is powered off, the cooling water can enter the heat exchanger 5 through the inlet pipe 8 and the circulating water inlet pipe 6. The heat insulation plate 4 has sliding grooves 11 on both sides inside, and a sealing plate 12 is provided in the sliding groove 11. The sealing plate 12 can seal the vent 9 to prevent heat flow from entering the heat exchanger 5.
