[0003] Currently, the heat storage process of the heat storage device consumes a large amount of thermal energy, has a slow heat exchange, and a relatively low overall working efficiency. Summary of the Invention

And a heat dissipation device is provided. When heat interaction is required, the heat dissipation device increases the heat removal in the heat storage body, thereby increasing the efficiency of heat interaction. By increasing the heat retention efficiency and the heat interaction efficiency, the overall working efficiency of the device is increased.

The lifting driving devices are arranged at the top of the upper heat storage housing. A group of air-water heat exchangers are also arranged inside the upper heat storage housing. A heat preservation structure is arranged on the inner end face of the upper heat storage housing. The heat preservation structure is communicated with the lower heat preservation housing. A heat preservation device is arranged inside the lower heat preservation housing;

[0007] The heat storage body group includes several groups of heat storage bodies. Each group of heat storage bodies is built by stacking several first heat storage bricks and several groups of second heat storage bricks. The first heat storage brick is a concave heat storage brick, and the second heat storage brick is a convex heat storage brick that cooperates with the first heat storage brick for building. An installation groove is processed on the first heat storage brick. Several groups of first semi-circular grooves are processed at the bottom of the installation groove. One group of first heat dissipation semi-circular ventilation holes is processed on each of the two shoulders of the first heat storage brick; A protruding end is processed on the second heat storage brick. A second semi-circular groove that cooperates with the first semi-circular bottom groove is processed on the protruding end. One group of second heat dissipation semi-circular ventilation holes that cooperate with the first heat dissipation semi-circular ventilation holes is processed on each of the two shoulders of the second heat storage brick;

[0008] The first heat storage brick and the second heat storage brick are cooperatively built.

[0010] Furthermore, the lifting drive device includes a group of lifting drive hydraulic cylinders. The lifting drive hydraulic cylinders are installed in a group of heat insulation covers. The lifting drive hydraulic cylinders are arranged horizontally. The movable end of the lifting drive hydraulic cylinder is fixedly connected to a group of lifting steel wires. The other end of the lifting steel wire passes through a group of steering wheels and is fixedly connected to four groups of lifting ropes. The other ends of the four groups of lifting ropes are fixed on four lifting ears fixed on the top of the sealing protection cover.

[0011] Furthermore, the heat insulation structure includes a heat insulation inner shell. The heat insulation inner shell is fixedly arranged inside the upper heat storage shell.

When the water is stored to the set water level, the liquid level sensor senses the liquid level and transmits the signal to the controller. The controller controls the primary pipeline control solenoid valve to close, and the primary cold water inlet pipe stops storing water inside the lower heat preservation housing. And during the water storage process, the heat preservation heating pipe continuously heats the cold water until the water is heated to boiling. At this time, the temperature sensor senses the signal and transmits the temperature signal to the controller. The controller controls the secondary pipeline control solenoid valve to open, and the secondary cold water inlet pipe starts to store water inside the lower heat preservation housing. At the same time, the cold water discharged from the secondary cold water inlet pipe forms a convection with the existing hot water, accelerating the boiling progress of the secondary cold water and saving heating electric energy.

The return spring is sleeved on the outer end of the corrugated connecting pipe. The electromagnetic plug connector is a frustum-shaped plug connector that cooperates with the metal interface. A group of electromagnets are arranged inside the electromagnetic plug connector. The electromagnet is electrically connected to an external power source through a wire and a control switch;

[0015] The sub-heat dissipation pipes realize automatic adsorption and dispersion through the cooperation relationship between the electromagnetic plug connectors and the metal interfaces, ensuring that when the heat dissipation device needs to work to accelerate the discharge of heat in the heat storage body, the connection of the heat dissipation device can be completed without manual operation. And when the heat dissipation device does not need to work, the electromagnetic plug connectors can be reset through the spring action to realize the removal of the heat dissipation device. It can be operated controllably through simple automation without manual implementation, avoiding the possibility of accidents.

The controller controls the first-stage pipeline control solenoid valve to close, and the first-stage cold water inlet pipe stops storing water inside the lower heat preservation housing. During the water storage process, the heat preservation heating pipe continuously heats the cold water until the water is heated to boiling.

At the same time, the cold water discharged from the second-stage cold water inlet pipe forms convection with the existing hot water, accelerating the boiling progress of the secondary cold water and saving heating electric energy;

[0018] Step b: Activation of the heat storage body group: Turn on the heating pipes in the installation holes to build heat storage for several first heat storage bricks and several groups of second heat storage bricks. At this time, the sealing protection cover is sleeved on the outer end of the heat storage body, accelerating the heat storage process of the heat storage body;

[0019] Step c: Heat retention: The hot water in the heat preservation device continuously boils, forming a large amount of steam, which enters the hollow heat preservation layer of the heat preservation structure through the intermediate pipeline, achieving efficient preservation of the heat stored by the heat storage device;

[0020] Step d: Heat release: Drive the sealing protection cover to rise through the lifting drive device, so that the heat in the heat storage body can be exchanged. At this time, turn on the electromagnetic plug on the heat dissipation device, and make it achieve engagement through the magnetic mutual attraction cooperation relationship between itself and the metal interface. At this time, turn on the heat dissipation motor, and the heat dissipation motor works to discharge the heat from the heat storage body through the heat dissipation air, and the air-water heat exchanger realizes the heat interaction of the heat storage device.

[0021] The present invention has the following beneficial effects compared with the prior art:

[0022] By setting the lower heat preservation housing and arranging the heat preservation device inside the lower heat preservation housing, the present invention ensures a long storage time of the stored thermal energy.

The controller (7-7) controls the first-stage pipeline control solenoid valve (7-3) to close, and the first-stage cold water inlet pipe (7-1) stops storing water inside the lower heat preservation housing (2). During the water storage process, the heat preservation heating pipe (7-8) continuously heats the cold water until the water is heated to boiling. At this time, the temperature sensor (7-6) senses the signal and transmits the temperature signal to the controller (7-7). The controller (7-7) controls the second-stage pipeline control solenoid valve (7-4) to open, and the second-stage cold water inlet pipe (7-2) starts to store water inside the lower heat preservation housing (2). At the same time, the cold water discharged from the second-stage cold water inlet pipe (7-2) forms convection with the existing hot water, accelerating the boiling progress of the secondary cold water and saving heating electric energy; Step b: Activation of the heat storage body group: Turn on the heating pipe (3-3) in the installation hole to store heat for several first heat storage bricks (3-1) and several groups of second heat storage bricks (3-2). At this time, the sealing protection cover (4) is sleeved on the outer end of the heat storage body (3), accelerating the heat storage process of the heat storage body (3); Step c: Heat retention: The hot water in the heat preservation device (7) continuously boils, forming a large amount of steam, which enters the hollow heat preservation layer (6-4) of the heat preservation structure (6) through the intermediate pipeline (6-5), achieving efficient preservation of the heat stored by the heat storage device; Step d: Heat release: Drive the sealing protection cover (4) to rise through the lifting drive device (5) so that the heat in the heat storage body (3) can be exchanged. At this time, turn on the electromagnetic plug connector (9-4) on the heat dissipation device (9), and make it achieve engagement through the magnetic mutual attraction cooperation relationship with the metal interface (8-1). At this time, turn on the heat dissipation motor, and the heat dissipation motor works. The heat is discharged from the heat storage body (3) through the heat dissipation air, and the heat of the heat storage device is exchanged by the air-water heat exchanger.
