Claims

[Scope of utility model registration request]

(1) The first side, the second side, the third side, and the fourth side are opposite to each other.
is formed inside a rectangular flat body having sides, and the first
a first flow path inclined at an angle A with respect to the side; a second flow path provided on the second side side and parallel to the first flow path;
The flow path and the second flow path are connected, and an angle B is made with respect to the third side and the fourth side.
a large number of third flow channels parallel to each other through narrow strip-shaped seal portions, one end of which is connected to the largest cross-sectional end of the first flow channel, and the other end of which extends through the second side and connects to a cold water inlet. 7. The cross-sectional area of the first flow path decreases from the upstream side to the downstream side, and the cross-sectional area of the second flow path decreases from the upstream side to the downstream side. expands as it progresses,
and near the maximum cross-sectional end of the first flow path, the first
The third portion closest to the maximum cross-sectional end on the inner surface on the first side of the flow path.
1. A solar heat collector characterized in that a step-shaped inlet portion is provided at a position where one inlet of a flow path faces each other to prevent fluid from flowing from a large cross-section side to a small cross-section side.

(2) On the downstream side of the first step on the inner surface of the first side of the first channel, a number of step-like intermediate steps are provided to prevent the flow of fluid from the large cross-section side to the small cross-section side. A solar heat collector according to claim 1 of the utility model registration claim.

(3) The boundary line between the narrow strip-shaped seal portion and the third flow path is a straight line, and the boundary line between the first and second flow paths is arc-shaped, and
The solar heat collector according to claim 2, wherein the arcuate boundary line intersects and continues with the straight line on the fourth side and smoothly continues with the straight line on the third side.
