Description
Technical Field
The invention relates to a heat storage device, in particular to a solid-state heat storage device.
Background
At present, the internal structure of the heat storage device is that a heating element is arranged in a heat storage body, heat generated by the heating element is stored in the heat storage body, when heat is released, the stored heat is gradually released through a heat release medium, under the use condition that the heat is released while the heat is stored, the phenomenon that the heat lost at the front end is far greater than the heat lost at the rear end along the flow direction is generated due to the flow direction problem of the heat release medium, and the heat storage performance of the heat storage body material cannot be fully utilized. Meanwhile, the front end and the rear end of the heat storage body are used at different temperatures for a long time, so that the phenomenon of uneven service life of the heat storage material occurs, and the performance and the service life of the whole heat storage device are further affected.
Disclosure of Invention
The invention aims to provide a direct-heat independently arranged heat storage device structure capable of improving the overall heat storage performance and the service life of a heat storage material.
The purpose of the invention is realized in the following way:
the invention relates to a heat storage device structure with independent direct heat arrangement, which is characterized in that: the heat-insulating material is internally divided into a heat storage cavity and a direct heating cavity after the heat-insulating material is rotated along an axis of the heat-insulating material, a heat storage body is arranged in the heat storage cavity, a heat storage heating element is arranged between the heat storage bodies, the direct heating cavity is internally provided with the direct heating element, a heat-releasing medium inlet channel and a heat-releasing medium outlet channel are arranged in the direct heating cavity, and the heat storage cavity is internally provided with the heat storage inlet channel and the heat storage outlet channel.
The invention may further include:
1. after the heat-release medium guide structure divides the inside of the heat-insulating material into a heat storage chamber and a direct heating chamber, the heat-release medium flows through the direct heating chamber to exchange heat with the direct heating element, directly release heat outwards, and the heat storage heating element of the heat storage chamber stores heat for the heat storage body.
2. The heat release medium guiding structure rotates in the opposite direction to communicate the heat storage chamber with the direct heating chamber, and simultaneously the heat release medium guiding structure separates the rest part of the direct heating chamber from the heat release medium inlet channel and the heat release medium outlet channel, and the heat release medium flows through the heat storage chamber to exchange heat with the heat storage body and release heat outwards.
The invention has the advantages that: according to the invention, through the two independent chambers, under the working condition that the heat storage device stores heat while discharging, a heat release medium passes through the direct heating chamber only provided with the heating element, and the heat storage chamber with the built-in heating element only stores heat; under the condition of only putting and not storing, the heat release medium passes through the heat storage cavity, so that the whole heat storage device can release heat outwards at any time. Therefore, the phenomenon of nonuniform temperature inside the heat storage body caused by the flow direction of the heat release medium is avoided, the temperature inside the heat storage body is uniformly increased, the heat storage performance of the heat storage body is fully utilized, the highest temperature of the heat storage body under the condition of the same heat storage capacity is reduced, and the service life is prolonged.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The invention is described in more detail below, by way of example, with reference to the accompanying drawings:
in combination with fig. 1, the invention is a heat storage device structure with independent direct heat arrangement, a heating element 3 is arranged in a direct heat chamber 1, a heating element 4 and a heat storage body 4 are arranged in a heat storage chamber 2, a heat preservation material 5 is used for carrying out integral heat preservation on the heat storage device, and a heat release medium flowing chamber is regulated through a heat release medium guiding structure 6.
Under the working condition of storing and releasing simultaneously, the heat release medium guiding structure 6 is positioned at a solid line position as shown in the figure, the heat release medium flows through the direct heating chamber 1 to exchange heat with the heating element 3, and directly releases heat outwards, and the heating element 3 in the heat storage chamber 2 stores heat to the heat storage body 4. Under the working condition that the heat storage medium is not stored, the heat release medium guide structure 6 is positioned at the position of a dotted line as shown in the figure, and the heat release medium flows through the heat storage cavity 2 to exchange heat with the heat storage body 4 and release heat outwards. In the heat storage process, the heat release medium does not flow through the inside of the heat storage body, so that the phenomenon that the heat loss at the front end is far greater than the heat loss at the rear end along the flow direction is avoided, the temperature in the heat storage body is uniformly increased, the heat storage performance of the heat storage body is fully utilized, the highest temperature of the heat storage body under the condition of the same heat storage capacity is reduced, and the service life is prolonged.
