Heat storage body and heat storage structure of heat storage body, forming die and manufacturing method

Abstract

The invention discloses a heat storage body and a heat storage structure of the heat storage body, a forming die and a manufacturing method. A plurality of scaling type fluid channels are formed in the heat storage body. The wall face profile of each scaling type fluid channel is of a shape formed in a mode that a busbar formed by at least two sections of circular arcs and tangent lines among the circular arcs rotates around a central shaft for a circle. Moreover, a male die of the forming die is embedded on an upper die base in a sleeved mode, and the forming portion of the male die protrudes out of the upper die base. The position, corresponding to the male die, of one end of a channel assisted forming rod of the forming die is fixed to a lower die base, the other end of the channel assisted forming rod corresponds to the male die and stretches out upwards. When the forming die is used, the end face of the male die forming portion makes contact with the end face of the extended end of the channel assisted forming rod. The scaling type fluid channels of the heat storage body change smoothly, so that the heat exchange rate is improved, basically no flow resistance is added and blocking cannot occur easily; the male die is fixed to the upper die base in an embedded and sleeved mode, so that difficulties in manufacturing dies are lowered; and it is guaranteed that the scaling type fluid channels pressed out through dies are completely through by means of the channel assisted forming rod.

Description

Technical field [0001] The invention relates to a heat storage material and a mold and method thereof, in particular to a heat storage body and a heat storage structure thereof, a forming mold and a manufacturing method. Background technique [0002] Nowadays, with the development of society, people's demand for energy is increasing. Regenerative heat exchanger is one of the effective means to recover waste heat, save fossil fuels, and reduce carbon dioxide and nitrogen oxide emissions. The key technology of the regenerative heat exchanger is the structure of the heat storage body. At present, the commonly used heat accumulators include regular heat accumulators and random heat accumulators, such as honeycomb regular heat accumulators, heat accumulator balls, etc. These heat accumulators still have many disadvantages under certain use environments, such as fluid flow. The resistance is large, the heat exchange rate is not high, and it is easy to be blocked. Therefore, not all e...
