Description
Technical Field
The utility model relates to the technical field of heating, in particular to a phase change heat storage unit.
Background
At present, most areas in China still adopt a coal-fired mode for heating, coal belongs to non-renewable energy, and the coal has the defects of low heat conversion rate, air pollution, environmental pollution and the like, so that more and more clean energy sources are used for heating, and the common application of electricity makes electric heating preferred.
The heat storage material is selected to be a product which has large latent heat of phase change, proper phase change temperature and no toxicity and pollution, and the sealing property of the heat storage body is ensured.
The existing common heat storage materials are uneven, or the heat storage capacity is small, or the materials are toxic; the supercooling degree of the material is high, and the temperature stratification is serious; the existing preparation method of the heat storage unit cannot ensure the sealing property. Accordingly, the present invention is directed to a phase change heat storage unit that solves the problems set forth in the background art.
Disclosure of Invention
The present invention is directed to a phase change heat storage unit that solves the problems set forth above in the background art.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model provides a phase change heat accumulation unit, includes lug, upper cover, section of thick bamboo wall, low head, the welding of section of thick bamboo wall upper end has the upper cover, and the welding of section of thick bamboo wall lower extreme has the low head, is equipped with the seal receptacle on the upper cover, is equipped with sealed stifled in the seal receptacle, sealed stifled and seal receptacle threaded connection, sealed stifled and seal receptacle junction are equipped with the sealing washer.
As a further scheme of the utility model, the upper surface of the upper end enclosure is welded with a lifting lug.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model increases the heat storage capacity, has no toxicity and harm to the material, reduces the supercooling degree of the material, reduces the temperature stratification problem and can effectively improve the sealing property of the heat storage unit.

Fig. 2 is an enlarged view of a portion a of fig. 1 in the phase-change heat storage unit.
In the figure: 1. lifting lugs; 2. an upper end enclosure; 3. a cylinder wall; 4. a lower end enclosure; 5. sealing and blocking; 6. a seal ring; 7. and (4) a sealing seat.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 2, in an embodiment of the present invention, a phase change heat storage unit includes a lifting lug 1, an upper sealing head 2, a cylinder wall 3, and a lower sealing head 4, where the upper end of the cylinder wall 3 is welded with the upper sealing head 2, the lower end of the cylinder wall 3 is welded with the lower sealing head 4, the upper sealing head 2 is provided with a sealing seat 7, a sealing plug 5 is arranged in the sealing seat 7, the sealing plug 5 is in threaded connection with the sealing seat 7, a sealing ring 6 is arranged at a connection position of the sealing plug 5 and the sealing seat 7, and the lifting lug 1 is welded on the upper surface of the upper sealing head 2.
The working principle of the utility model is as follows: sodium acetate trihydrate, disodium hydrogen phosphate dodecahydrate and sodium carboxymethylcellulose are adopted to be heated according to a certain proportion, continuously stirred at constant temperature and fully mixed, and then poured into the cylinder wall 3 when the mixture is in a liquid state, and then the sealing plug 5 is immediately screwed down, so that the novel negative pressure at normal temperature is ensured.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
