Specific embodiment
As Figure 1-5, a kind of shield machine external circulating water-cooled but device, including circulating water pool 1, the termination of circulating water pool 1 peace
Equipped with water pump, the water inlet pipe of water pump is stretched into circulating water pool 1, and the both sides of circulating water pool 1 are respectively provided with framed bent 2, is set up on two framed bents 2
There is frame-type radiating tube 3, the one end of circulating water pool 1 is provided with blower fan temperature control system；
In frame-type radiating tube 3, both sides pipe is respectively arranged on framed bent 2, and many pass through multiple three-way connections communicating pipe 3-6
3-3 compositions side pipe, many radiating tube 3-5 between the pipe of both sides by being arranged in parallel are connected, and outlet pipe and the frame-type of water pump dissipate
The water inlet pipe reducer union 3-1 connections of heat pipe 3, offer multiple louvres 5 on each tube wall of radiating tube 3-5, frame-type dissipates
The pipeline at turning is connected by straight bent sub 3-4 on heat pipe 3；
In blower fan temperature control system, temperature sense controller is installed in circulating water pool 1, temperature sense controller passes through wire
Switch with blower fan 4 is electrically connected.
Butterfly valve 3-7 is provided with the outlet pipe 3-8 of frame-type radiating tube 3.
In radiating tube 3-5, multiple louvres 5 symmetrically divide two-layer to arrange and positioned at scattered along radiating tube 3-5 longitudinal sections center line
The middle and lower part of heat pipe 3-5, the arranged for interval of two-layer louvre 5.
Blower fan 4 is arranged on the blower fan pedestal 6 on the side of circulating water pool 1.
Flowmeter 3-2 is installed on water inlet pipe reducer union 3-1；Blower fan 4 is preferably the low-noise energy-saving pipe of 3 kilowatts of power
Road formula ventilation blower.
Circulating water pool 1 forms retaining pond by grey brick masonry, sand finish or using section bar steel plate welding processing.
Framed bent 2 is the framed bent processed using square tube, longitudinally mounted length, width according to frame-type radiating tube 3 and
The width comprehensive process of circulating water pool is formed.
