Description

There is not the infiltration cooler

The utility model relates to a kind of nothing infiltration cooler, has the basic refrigerating function of existing cooler, also has cooling medium and the nothing that is cooled between the medium interpenetrates and function such as dielectric leakage display alarm.

Though existing internal combustion engine, steam engine, water wheels unit, refrigeration unit have the difference of size, shape etc. with cooler, but all being based on cooling medium flows in segregate passage separately with the medium that is cooled, carry out heat exchange by separation layer, reach cooling purpose.Separation layer generally all uses the heterotype tubing (circular cross-section, square-section etc.) of One's name is legion to be welded, and to increase the area of heat exchange, improves the efficient of heat exchange, also promptly improves the efficient of refrigeration.Since in the cooler cooling medium and be cooled medium with at a high speed, high pressure long-term wash away, burn into cavitation pitting, vibration, the weld seam of cooling tube is cracked through regular meeting, cause cooling medium and the medium that is cooled interpenetrates by crackle.This infiltration is the infiltration of a kind of slow property, is not easy to be found very much, and only breaks down in system, could check out after the shutdown, and place under repair, replacing, and change new medium, and will cause the pause of producing and working like this, cause greater loss.

Task of the present utility model is, a kind of nothing infiltration cooler is provided, be used for cooling systems such as internal combustion engine, steam engine, water wheels unit, refrigeration unit, eliminate cooler because in a single day crackle takes place the cooling tube weld seam, the cooling medium and the interpenetrative defective of medium that is cooled, has dielectric leakage display alarm function simultaneously, the leakage situation of real time monitoring medium.

The nothing infiltration cooler that the utility model provides, has the cooling medium entrance and exit, medium inlet and outlet are cooled, the cooling medium chamber, cooling tube, the cooling tube ring flange, the runner baffle plate, middle casing, sealing rubber ring, go into end casing and go out end casing, it is characterized in that: by cooling tube, the cooling tube ring flange, cooler core body that the runner baffle plate constitutes and middle casing the cooling medium chamber with go into the end dielectric cavity that is cooled, the cooling medium chamber is cooled and is formed into the end separate cavities between the dielectric cavity respectively and goes out to hold separate cavities with going out end, and in separate cavities bottom separately breather pipe is set respectively, connect the dielectric leakage displaying alarm, form respectively and go into to hold the separate cavities display alarm and go out to hold the separate cavities display alarm.

The nothing infiltration cooler that the utility model provides, it is characterized in that: be respectively equipped with anti-cavitation pitting baffle plate at the cooling medium inlet and the inner end, medium inlet that is cooled, to prevent that cooling medium and the medium high speed that is cooled, high pressure from washing away cooling tube, cause cavitation pitting, reduce the generation of bead crack.

Task of the present utility model is achieved like this, on existing cooler construction basis, two cooling tube ring flanges that increase newly and cooling tube welding, constitute into the end separate cavities with original two cooling tube ring flanges respectively and go out to hold separate cavities, at two breather pipes going into to hold separate cavities and go out to hold separate cavities middle casing bottom to install, make the pressure of two separate cavities keep the pressure identical, can in time the medium that leaks be discharged separate cavities with atmospheric pressure.When the high pressure cooling medium in the cooling medium chamber leaks by the bead crack generation of ring flange, by separate cavities its pressure is reduced to atmospheric pressure, and cooling medium is emitted by breather pipe like this.In like manner, when the medium that is cooled takes place to leak, also emit by breather pipe.Because the step-down buffer action of separate cavities has realized that the cooling medium and the medium that is cooled do not have interpenetrative function.By anti-cavitation pitting baffle plate being set respectively, avoided high speed, high pressure cooling medium and the medium that is cooled to wash away cooling tube strongly and formed cavitation pitting at the cooling medium inlet and the place, medium inlet that is cooled.Because going into to hold separate cavities and going out to hold on two breather pipes of separate cavities setting two dielectric leakage display alarms have been installed, thereby can in time dielectric leakage shown in real time and report to the police, supply equipment operating personnel and maintenance personal grasp situation at any time.Thereby nothing infiltration that the utility model proposes and the task that dielectric leakage is shown and reports to the police have in real time been realized.

The utility model is compared with existing cooler has following advantage: (1) cooling medium and be cooled between medium not have and interpenetrate; (2) can show in real time and warning dielectric leakage; (3) safe in utilization; (4) cooling effect is stable; (5) life-span is long, good in economic efficiency.
