Thermal storage brick for forming vertical and multiple horizontal branch circuit stereoscopic air circuit system

Abstract

The invention provides a thermal storage brick for forming a vertical and multiple horizontal branch circuit stereoscopic air circuit system, and belongs to the technical field of thermal storage. Thethermal storage brick for forming the vertical and multiple horizontal branch circuit stereoscopic air circuit system comprises a horizontal groove, vertical grooves, an anchoring bulge and the like.Vertical air channels horizontal in space are formed through the vertical grooves, and communicate with a horizontal channel formed by the horizontal groove, and the three-dimensional stereoscopic air circuit system is established by arranging the vertical air channels in a stagger mode to form an air intake and discharge main circuit and enabling the horizontal channel to automatically form multiple branches of branch circuits connected in parallel. The thermal storage brick for forming the vertical and multiple horizontal branch circuit stereoscopic air circuit system fully uses the chimneyeffect, and merges the upper surface, the lower surface and the side surfaces of the thermal storage brick into the heat exchange air channel, thereby achieving air intake temperature difference balance, heat exchange area increase, temperature gradient reduction, heat exchange flow promotion, air channel pressure equilibrium and the like, significantly reducing temperature differences among different thermal storage bricks and among different space parts on the same thermal storage brick, and improving thermal storage capacity, heat absorption and release efficiency and dynamic response performance, and furthermore fully uses the original structure to form an engagement anchoring relation, and simplifies the structure and processing technology of the thermal storage brick.

Description

technical field [0001] The invention relates to a heat storage brick structure, in particular to a heat storage brick capable of forming a three-dimensional air passage system in which a vertical main air passage is combined with a plurality of horizontal branches. It belongs to the technical field of heat storage. Background technique [0002] As the basic unit of solid heat storage devices, heat storage bricks have a variety of mature and applied structures. However, after the current solid heat storage bricks constitute the entire heat storage device, the air ducts for ventilation and heat dissipation formed are essentially two-dimensional structures, and the typical and commonly used air duct structures are alternate and orthogonal on the horizontal plane. Its characteristic is that each air channel independently runs through the entire heat storage body and is completely isolated from each other. The heating wires are generally located in multiple sets of parallel chan...

[0005] In addition, on the anchoring of heat storage bricks, the Chinese patent "A self-anchor positioning heat storage brick (application number: 201621233886.5)" is provided with meshing self-anchor blocks and self-anchor gaps on both sides of the heat storage bricks. Although it is helpful for fixing, it is still a two-dimensional air duct structure; and the flue is provided with a wave-shaped inner surface, but the structure is parallel to the flue, and it is difficult to form a turbulent effect that can promote sufficient heat exchange.

[0006] Excessive temperature differences between different heat storage bricks and different space parts of the same heat storage brick will reduce the overall heat storage temperature, thereby reducing heat storage capacity, affecting heat absorption and heat release characteristics, and reducing heat storage system efficiency and dynamic response performance ; If the temperature of the enclosed space of the heating wire is too high, it will significantly reduce the service life of the heating wire, etc.
