Description

Technical Field

[0001] The utility model belongs to the technical field of heating devices, in particular to an energy storage heating device based on phase change materials. Background Art

[0002] Phase change material refers to a material that changes its state and provides latent heat without changing the temperature. The process of changing physical properties is called phase change process. At this time, the phase change material will absorb or release a large amount of latent heat, thereby achieving energy saving and better temperature control effect.

[0003] In some places that require high temperature environment and thermal insulation, such as indoor heating of residential and commercial buildings, farmers, incubators, agricultural greenhouses and other places, in order to maintain a high temperature environment, it is usually necessary to use a heating device to increase the temperature. The heating device generally generates heat by energizing the heating source, and then dissipates the heat to achieve the heating effect. During its use, due to the high temperature of the heating source, the heating source needs to heat up quickly. Therefore, when it is powered off, the heat it has will also dissipate quickly, so that the heating source needs to be powered on frequently to meet the heat demand, which is a waste of energy and needs to be improved.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 5 As shown, the utility model provides an energy storage heating device based on phase change material, comprising a first metal tube 1, and a movable cover 2, which is threadedly assembled on the first metal tube 1;

[0026] A thermostat 3, which is fixedly connected to the movable cover 2;

[0027] An electric heating rod 4, which is fixedly mounted on the movable cover 2;

[0028] An energy storage mechanism 5, which is fixedly mounted inside the first metal tube 1 and is used to store the heat emitted by the electric heating rod 4;

[0029] The energy storage mechanism 5 includes an energy storage block 501, a limit block 502, a first energy storage rod 503 and a support block 504. The energy storage block 501 is fixedly installed inside the first metal tube 1, the limit block 502 is fixedly connected to the energy storage block 501, the first energy storage rod 503 is slidably assembled on the outside of the limit block 502, and the support block 504 is fixedly connected to the first energy storage rod 503.

[0030] By adopting the above scheme, the first energy storage rod 503 can be supported and limited by the limit block 502, so that the first energy storage rod 503 can be installed inside the first metal tube 1 and be misaligned with the energy storage block 501, and due to the limitation of the limit block 502, the first energy storage rod 503 can only move in one direction, which can improve the stability of the first energy storage rod 503 after installation, and the support block 504 can limit the electric heating rod 4.

[0031] like Figure 1 As shown, the left end of the first metal tube 1 is fixedly connected to the second metal tube 601 , and the length of the second metal tube 601 is the same as that of the first metal tube 1 .

[0032] By adopting the above scheme, through the design of the second metal tube 601, since the length of the second metal tube 601 is the same as the length of the first metal tube 1, the electric heating rod 4 can also be fully inserted into the interior of the second metal tube 601. Similarly, the shapes of the first metal tube 1 and the second metal tube 601 can be circular tubes, and can also be other shapes, such as square and rectangular shapes. The specific shape is adapted to the specific application environment.

[0033] like Figure 1 As shown, the external thread of the second metal tube 601 is sleeved with a sealing cap 602 , and the second metal tube 601 has the same thread as the internal thread of the movable cover 2 .

[0034] By adopting the above solution, through the design of the sealing cap 602, when the sealing cap 602 is installed on the outside of the second metal tube 601, the second energy storage rod 702 inside the second metal tube 601 can be blocked, so that the second energy storage rod 702 cannot move, and the sealing cap 602 and the movable cover 2 can exchange the installation position.

[0035] like Figure 5 As shown, a mounting plate 701 is fixedly connected to the interior of the second metal tube 601 , and a second energy storage rod 702 is slidably mounted inside the mounting plate 701 .

[0036] By adopting the above scheme, through the design of the second energy storage rod 702, when the electric heating rod 4 is located inside the second metal tube 601 and is energized to generate heat, the second energy storage rod 702 can absorb the heat emitted by the electric heating rod 4, thereby storing the heat. After the electric heating rod 4 stops heating, the second energy storage rod 702 can emit the stored heat.

[0037] like Figure 3 As shown, the first energy storage rod 503 has a triangular shape, there are six first energy storage rods 503 , and the six first energy storage rods 503 form a circle and the interior thereof is a hexagon.

[0038] By adopting the above solution, through the design of the first energy storage rod 503, it is possible to store as much heat dissipated by the electric heating rod 4 as possible when the electric heating rod 4 is heating, thereby fully absorbing and storing the heat.

[0039] like Figure 4 As shown, the length of the limiting block 502 is less than the length of the first energy storage rod 503 , and the limiting block 502 completely passes through the left end of the first energy storage rod 503 .

[0040] With the above solution, through the design of the limit block 502, the first energy storage rod 503 can only be inserted into the first metal tube 1 from the left end, and when the limit block 502 completely enters the first energy storage rod 503, it will be limited.

[0041] like Figure 3 and Figure 5 As shown, the first energy storage rod 503 and the second energy storage rod 702 are both made of phase change energy storage material, and the first energy storage rod 503 and the second energy storage rod 702 have different shapes.

[0042] By adopting the above solution, more heat can be stored through the phase change energy storage material, thereby achieving a better indirect temperature regulation effect. At the same time, the first energy storage rod 503 and the second energy storage rod 702 can be used in different environments.

[0043] The working principle and use process of this utility model:

[0044] First, the operator can install the first energy storage rod 503 into the first metal tube 1, so that the limit block 502 is located inside the first energy storage rod 503, and insert the second energy storage rod 702 into the installation switch 701, then the operator can fix the sealing cap 602 on the first metal tube 1 or the second metal tube 601, and then inject heat transfer medium such as heat transfer oil or water into the first metal tube 1 and the second metal tube 601, and install the movable cover 2 on the other of the first metal tube 1 or the second metal tube 601, and then The operator can start the thermostat 3 to control the electric heating rod 4 to heat. At this time, the heat-conducting medium inside the first metal tube 1 and the second metal tube 601 will be heated, and the first energy storage rod 503 and the second energy storage rod 702 will absorb the heat of the heat-conducting medium and store it when the electric heating rod 4 heats the heat-conducting medium. When the electric heating rod 4 stops heating, the operator can rotate to remove the movable cover 2 and the sealing cap 602, pour out the heat-conducting medium and use it as a heat source, and the first energy storage rod 503 and the second energy storage rod 702 can be removed for use.
