The heat exchange efficiency of heat regenerator can pass through the heat transport fluid of the temperature and discharge of the heat transport fluid of input
Temperature embodies, if temperature when heat transport fluid inputs is equal with temperature when discharge, shows changing for heat regenerator
The thermal efficiency is zero, whereas if heat transport fluid input when temperature and discharge when temperature difference it is very big, then show that heat accumulating type changes
The heat exchange efficiency of hot device is very high, i.e., the temperature gradient along heat regenerator heat transport fluid flow direction is bigger, then heat accumulating type
The heat exchange efficiency of heat exchanger is higher.
Existing heat regenerator generally uses ceramic honey comb or Ceramic Balls as heat storage, and ceramic honey comb therein stores
Hot surface area per unit volume is larger, thus unit time heat output is larger, can allow the switching time of heat regenerator is short, temperature gradient
Greatly, but honeycomb ceramic heat accumulator is frangible in the continually changing environment of temperature, and durability is poor, needs to store the ceramic honey comb gone to sticks and staves
Hot body is replaced, and since the update cycle is shorter, therefore the use cost of honeycomb ceramic heat accumulator is very high；Although Ceramic Balls are not easy

Specific heat about 0.12kcal/kg.K, the specific heat of aluminium about 0.22kcal/kg.K.The specific heat of heat storage is bigger, the storage of identical weight
The amount of stored heat of hot body is bigger, and vice versa.
Existing heat accumulating type gas-gas heat exchange equipment, since its heat storage is an overall structure, the heat in heat storage hot end
It can quickly be transmitted to cold end along heat storage, cause heat accumulating type gas-gas heat exchange equipment to the recovery efficiency of thermal energy in high-temperature gas
It is ideal not to the utmost.
In order to reduce the heating conduction of heat storage, so that heat storage is generated the biggish temperature difference, heat recovery rate is improved, if each
Compartment of terrain is equipped with multiple heat storages in heat exchanger channels, is isolated between two heat storage layers with air or thermal insulation material, then by
In having separated the flash heat transfer channel between heat storage layer, temperature gradient can be allowed to increase, while can also reduce equipment volume, improve
The switching frequency of heat accumulating type gas-gas heat exchange equipment, and increase substantially heat recovery rate.
