Title:
HEAT COLLECTION RECEIVER
Document Type and Number:
Japanese Patent JP2017048926
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat collection receiver capable of performing heat exchange efficiently even when the size is small, and capable of securing long-term reliability as a crack hardly occurs.SOLUTION: A heat collection receiver has a first surface for receiving solar heat, and a second surface from which a heated gas is taken out on the opposite side from the first surface. The heat collection receiver is made of a ceramic porous body, and it has a plurality of first bottomed holes extending from the first surface side and a plurality of second bottomed holes extending from the second surface side. The gas introduced from the first bottomed holes passes the porous body and is exhausted from the second bottomed holes. Heat exchange is performed in the process of the gas passing through the porous body, so that a surface area of the heat collection receiver related to heat transmission can be enlarged. Also, the gas flow when passing through the porous body is disturbed by pores for constituting the porous body, so that heat exchange can be performed efficiently in a short section. Therefore, the heat collection receiver can be downsized, can become hard to crack and can secure long-term reliability, without deteriorating heat exchange performance.SELECTED DRAWING: Figure 1
