The oil cooler of existing single tube wall construction is solved, after tube wall rupture, crushing damage directly can be caused to main equipment, it is impossible to remedy
Problem.
To solve above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of bearing oil-water cooler for preventing leakage accident, it includes housing, and housing is provided with oil-in, oil-out, enters
The mouth of a river and delivery port, are provided with heat exchanger tube in housing, and heat exchanger tube is the tubular structure being made up of the first tube wall and the second tube wall,
First tube wall and the second tube wall are single-wall structure, and annular seal space is formed between the first tube wall and the second tube wall, set in annular seal space
There is at least one to the inclined ring flat-plate in side, be connected with the first tube wall and the second tube wall respectively, the low end in inclined ring flat-plate position
Discharge orifice is provided with, annular seal space bottom is connected with the detector being installed on outside housing.
Above-mentioned heat exchanger tube at least 2, heat exchanger tube is stylostome, and the second tube wall is looped around the first tube wall exterior, and second
Closed cavity is formed between tube wall and the first tube wall, the annular seal space of many heat exchanger tubes is interconnected.
Above-mentioned ring flat-plate is heat conduction ring flat-plate, and heat conduction ring flat-plate is annular metal sheet.
Above-mentioned detector is infrared electro leak detector.
A kind of bearing oil-water cooler for preventing leakage accident provided by the present invention, by adopting said structure, tool
There is following beneficial effect：Whether there is seepage in the first tube wall positioned at inner side or the second tube wall positioned at outside, can touch
Infrared electro leakage detection device is sent out, then infrared electro leakage detection device is reported to the police, and so remains to normal work in another layer of tube wall
In the state of find seepage failure in advance, it is ensured that on the premise of equipment remains to safe operation, can be with reasonable arrangement overhaul of the equipments.
Description of the drawings
With reference to the accompanying drawings and examples the invention will be further described：
Fig. 1 is the external structure schematic diagram of the present invention.
Fig. 2 is the profile of the present invention；
Fig. 3 is enlarged drawings of the Fig. 2 at I；
Fig. 4 is the structural representation of ring flat-plate in Fig. 3.
Specific embodiment
As shown in Figures 1 to 4, a kind of bearing oil-water cooler for preventing leakage accident, it includes housing 1, on housing 1
Oil-in 5, oil-out 6, water inlet 7 and delivery port 8 are provided with, in housing 1 heat exchanger tube 2 is provided with, heat exchanger tube 2 is by first pipe
The tubular structure that 9 and second tube wall of wall 10 is constituted, the first tube wall 9 and the second tube wall 10 are single-wall structure, the He of the first tube wall 9
Annular seal space 4 is formed between second, at least one is provided with annular seal space 4 to the inclined ring flat-plate 11 in side, respectively with the first tube wall 9 and
The tube wall 10 of tube wall 10 2 connects, and the low end in the position of inclined ring flat-plate 11 is provided with discharge orifice 12, it is ensured that in the first tube wall or
When two tube walls occur seepage, leak fluid can smoothly downstream to annular seal space bottom, so as to trigger infrared electro leak detector work
Make, to warn staff；Meanwhile, using this structure, remain to be found in advance in the state of normal work in another layer of tube wall
Seepage failure, it is ensured that on the premise of equipment remains to safe operation, can be with reasonable arrangement overhaul of the equipments；And can be prevented effectively from pipe
Wall ruptures, different medium mixing, prevent main equipment is caused crushing damage the occurrence of；The bottom of annular seal space 4 with
The detector 3 being installed on outside housing 1 connects.
Further, heat exchanger tube 2 at least 2, heat exchanger tube 2 is stylostome, and the second tube wall 10 is looped around outside the first tube wall 9
Closed cavity 4 is formed between face, and the second tube wall 10 and the first tube wall 9, the bottom of annular seal space 4 of many heat exchanger tubes 2 is interconnected,
Therefore when the tube wall of any one heat exchanger tube ruptures in many heat exchanger tubes, just can be very well by an infrared electro leak detector
Monitoring, reduce monitoring cost.
Further, ring flat-plate 11 is heat conduction ring flat-plate, and heat conduction ring flat-plate is annular metal sheet, so ring flat-plate 11 to be used for into this
In device, can guarantee that and fully carry out between the first tube wall 9 and the second tube wall 10 heat transfer, it is ensured that high efficiency heat exchange between medium.
The detector 3 is infrared electro leak detector.
Wherein, infrared electro leakage detection device 3 adopts infrared electro principle, when the outer tube wall of heat exchanger tube 2 or inner tubal wall go out
Existing seepage, oil or water enter annular seal space 4, when leak fluid touches sensor surface by the bottom flow passage of annular seal space 4 so as to light
Thread path changes, and infrared receiving tube is in cut-off state, and so as to trigger reverser upset, output is presented low level and absorbs electric current shape
State, promptly and accurately reports leakage scenarios, and produces sound alarm.
The infrared electro leakage detection device of many models can be applied to technical scheme, so the present invention does not have
The model of infrared electro leakage detection device is specified, this specification is no longer deeply repeated.
Using said structure, when using, heat exchanger tube 2 can be carried out with the presence or absence of seepage by infrared electro leak detector 3
Monitoring.Whether there is seepage in outer tube wall or inner tubal wall, can be transferred through infrared electro leakage detection device 3 and find and report to the police,
Another layer of tube wall remains to find seepage failure in the state of normal work in advance, it is ensured that equipment safety operation.
So, whether there is seepage in the first tube wall positioned at inner side or the second tube wall positioned at outside, can set out
Infrared electro leakage detection device, then the warning of infrared electro leakage detection device, so remains to normal work in another layer of tube wall
Find seepage failure under state in advance, it is ensured that on the premise of equipment remains to safe operation, can be with reasonable arrangement overhaul of the equipments.
