Adopt the improved flat type solar heat collector of improved plate type solar heat collection method preparation of the present invention, and the improved plate type solar hot-water heating system that comprises improved flat type solar heat collector, end with flat-plate heat pipe be can eliminate in flat type solar heat collector that existing flat-plate heat pipe forms and the hot-water heating system and defective and deficiency in the heat collection water tank are arranged at, make flat type solar heat collector can not be corroded, or surface scale, and problems such as sealing between flat type solar heat collector and the heat collection water tank have been solved.
The sealed at both ends encapsulation of through hole forms the micro heat pipe that works alone, be just to have contained join side by side and micro heat pipe that work alone more than two or two in the flat-plate heat pipe, certain micro heat pipe of contingency is damaged such as the work that also can not influence other micro heat pipe after the gas leakage like this.
Have the little fin with augmentation of heat transfer effect of extrusion modling on the through-hole wall, and the size of little fin is set and structure makes it to be suitable for and through-hole wall forms based on capillary slot, all can further improve heat flow density.
Part beyond described flat-plate heat pipe and heat collection water tank are contacted scribbles or is coated with solar energy absorbing coating, can be so that evaporator section absorbs solar energy more.
