Change the water flowing direction of cooling water pipe；First cooling water pipe and the second cooling water pipe side by side and the setting that contacts with each other, heat exchange efficiency
Height makes temperature field in water flowing mass concrete after cooling evenly, so as to more effectively reduce mass concrete knot
Temperature, pressure in structure reduces the cracking risk of mass concrete.
Further, first cooling water pipe and the second cooling water pipe are bound by iron wire in together.Preferably, along length
Direction is spent, binds the first cooling water pipe and the second cooling water pipe together every 1-4m iron wires.
Binding work can just complete before cooling unit is installed, and the Construction Arrangement of such cooling system can become more
For convenience.
Further, first cooling water pipe and the second cooling water pipe are integrally formed, and can facilitate installation, meanwhile, favorably
The raising of heat exchange efficiency between two cooling water pipes.
Further, first cooling water pipe and the second cooling water pipe are whole S-shaped, and cooling unit is in snake on the whole
Shape increases the heat exchange area of cooling unit and concrete.
Further, further include water inlet pipe and outlet pipe, the multiple cooling unit be connected in parallel on water inlet pipe and outlet pipe it
Between.
Further, in each cooling unit, the water outlet of the first cooling water pipe, water inlet respectively with outlet pipe, water inlet
Pipe connects, and water inlet, the water outlet of the second cooling water pipe are connected with water inlet pipe, outlet pipe.It so only need to be in cooling system
Both ends, corresponding water inlet pipe and outlet pipe are set respectively.
Further, the cross section of first cooling water pipe is circular or square.
Further, the cross section of second cooling water pipe is circular or square.
When first cooling water pipe and the second cooling water pipe use rectangular tube, the two is contacted by one side, contact area
Greatly, the heat exchange efficiency between the first cooling water pipe and the second cooling water pipe can be promoted, and be conducive to obtain more uniform temperature
.
Compared with prior art, the beneficial effects of the utility model are as follows：
1）Using the cooling system of the utility model, in mass concrete water flowing cooling procedure, need not pair
Water flowing direction in cooling water pipe is commutated, so as to reduce the difficulty of construction for pouring mass concrete；
2）The cooling water pipe that 2 water (flow) directions are reversed, when water flowing cools down, 2 are included in the utility model in cooling unit
Cancelling out each other along Cheng Shuiwen variations in root water pipe so as to make the temperature field of concrete after water flowing cools down evenly, reduces mixed
Coagulate the cracking risk of soil；
3）The cooling system of the utility model, it is simple in structure, it is easy to arrange in concreting storehouse surface.
