Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

Referring to fig. 1, the utility model provides a bulky concrete heat sink can cool down to bulky concrete structure is inside to reduce the difference in temperature in concrete structure surface, solved because the difference in temperature in concrete structure surface is big and produce the cracked problem of temperature. The mass concrete cooling device of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 to 3, the utility model discloses bulky concrete heat sink includes: a cooling pipeline 10 and a drainage network 20 which are pre-embedded in the concrete structure. The opening of the cooling duct 10 is exposed on the surface of the concrete structure so that the cold air or cold water can flow into the cooling duct 10, and the cooling duct 10 is provided with a through hole 13 for the cold air or cold water to pass through, so that the cold air or cold water contacts with the interior of the concrete to achieve the purpose of reducing the temperature of the interior of the concrete. Wherein cold air or cold water is introduced after the initial setting of the concrete, thereby not affecting the quality of the concrete structure.

Drainage network 20 is pre-buried in the concrete along with cooling pipe 10, and drainage network 20 wraps up in cooling pipe 10's outer wall, utilizes the characteristics that drainage network compressive property is good for form the gap between cooling pipe 10 outer wall and the concrete, concrete seal the through-hole when preventing pre-buried cooling pipe on the one hand, and on the other hand makes air conditioning or cold water in the cooling pipe flow into the gap through-hole 13, increase air conditioning or cold water and concrete structure's area of contact, thereby promote the cooling effect. Preferably, the drain net 20 is a three-dimensional composite drain net.

Specifically, as shown in fig. 2, the cooling duct 10 includes three straight pipes 11 surrounding a U shape and a right-angled bent pipe 12 connected to end portions of two adjacent straight pipes 11, and a through hole 13 is formed in an outer surface of each of the straight pipes 11. The straight tube 11 and the right angle elbow 12 are preferably PVC tubes.

Preferably, the through holes 13 are arranged in a quincunx shape, so that more through holes can be arranged on each straight pipe 11 to accelerate the speed of cold air or cold water flowing into the gap.

As shown in fig. 3, a plurality of cooling ducts 10 are generally installed in a mass concrete structure to accelerate a cooling rate and to equalize a temperature difference inside the concrete.

In the first embodiment, as shown in fig. 3 and 4, both duct ports of the temperature-decreasing duct 10 are opened to allow cool air to naturally flow into the duct. If necessary, one opening of the cooling duct 10 may be connected to a blower to accelerate the flow of cold air, thereby accelerating the cooling of the interior of the concrete.
