Abstract
The invention relates to a radiator for reducing stress and trimmer pressure. The radiator comprises a shell, wherein the inside of the shell is divided into a rear cooling cavity and an oil cooling cavity cut by a partition plate; the upper part of one end of the rear cooling cavity is provided with an air outlet, and the side part of the other end of the rear cooling cavity is provided with an air inlet; an oil inlet and an oil outlet are formed in the side surface of the oil cooling cavity in an upper-down interval manner, a bypass square tube is arranged on a cover plate positioned on the lower part of the oil cooling cavity, and the bypass square tube is communicated with the oil inlet. The radiator provided by the invention has the advantages that the structure is reasonable, the operation is simple, a condition that the radiator leaks because of oversize pressure and cold and hot stress concentration is reduced, and the reliable operation of the radiator in a compressor is guaranteed; the radiator provided by the invention can stably operate for a long time in a worm air compressor, and the leakage is not generated.
Description
Technical field
The present invention relates to the heat sink technology field, especially a kind of radiator that reduces stress and compensator or trimmer pressure.
Background technique
Large cube of oil gas radiator mainly uses more extensive in screw air compressor.
The critical piece of screw air compressor is screw rod head, Oil-gas Separation bucket.The screw rod head is air-breathing by suction filter and air intake control valve, and simultaneously oil injects air compression chamber, and head is carried out cooling, sealing and screw rod and bearing are lubricated, and pressing chamber produces pressurized air.The air-fuel mixture gas that generates after compression is discharged in the Oil-gas Separation bucket, and due to the effect of mechanical centrifugal power and gravity, most oil are separated from oil gas mixture.The air process is by the twice-laid gas-oil separating cylinder core of borosilicate glass, and nearly all mist of oil all is separated.
From above-mentioned working principle, we are not difficult to find that oil plays very important effect in whole compressor assembly.Oil energy cooling machine head, radiator can be completed the effect of cold oil preferably, and the quality of the cooling effect of radiator directly affects the usability of head.
Radiator of the prior art, it is into and out of the left and right two ends of the common setting of hydraulic fluid port with radiator, and difficult while arranging pipeline, increase takes up room.
Radiator of the prior art, medium pressure when the radiator is excessive to be caused grease chamber's weld cracking and because of the thermal shock core body internal channel stress that causes dispelling the heat, concentrates, and finally causes the spalling of core body internal channel, product leakage.Usability is poor, and radiating effect is poor.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of a kind of radiator that reduces stress and compensator or trimmer pressure rational in infrastructure, thereby improves the usability of radiator, increases its reliability, and good heat dissipation effect improves radiator working life.
The technical solution adopted in the present invention is as follows:
A kind of radiator that reduces stress and compensator or trimmer pressure, comprise housing, is divided into rear cold chamber and oil cooling chamber by dividing plate in described housing; The top that is positioned at rear cold chamber one end is provided with air outlet, is positioned at rear cold chamber the other end sidepiece and is provided with suction port; Be positioned at one side, oil cooling chamber and be arranged at intervals with up and down filler opening and oil outlet, be positioned at cover plate place, bottom, oil cooling chamber the bypass square tube is installed, described bypass square tube is communicated with filler opening.
Its further technological scheme is:
Be provided with two parallel square openings on described bypass square tube.
Beneficial effect of the present invention is as follows:
The present invention is rational in infrastructure, easy and simple to handle,, by setting up the bypass square tube, reduces to concentrate and cause radiator leak because of the excessive and cold and hot stress of pressure, has guaranteed radiator reliably working in compressor.
Radiator of the present invention is long-term, the stable work of energy in screw air compressor, does not produce leakage.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, the radiator that reduces stress and compensator or trimmer pressure of the present embodiment, comprise housing, is divided into rear cold chamber 3 and oil cooling chamber 4 by dividing plate 2 in housing; The top that is positioned at rear cold chamber 3 one ends is provided with air outlet 1, is positioned at rear cold chamber 3 the other end sidepieces and is provided with suction port 8; Be positioned at 4 one sides, oil cooling chamber and be arranged at intervals with up and down filler opening 6 and oil outlet 7, be positioned at oil cooling chamber 4 bottom cover plates (not shown in FIG.) and locate to be equipped with bypass square tube 5, bypass square tube 5 is communicated with filler opening 6.
As shown in Figure 3, be provided with two parallel square openings 9 on bypass square tube 5.
The present invention is arranged in 4 same sides, oil cooling chamber with filler opening 6 and oil outlet 7, facilitates discharging and the layout of pipeline, takes up room little.
The present invention in actual use, can realize single process, and when filler opening 6 oil-feed, at first oil enter in bypass square tube 5, and do not occur cooling, by bypass square tube 5 enter again carry out in oil cooling chamber 4 cooling.
The present invention is positioned at cover plate (not shown in FIG.) and locates to be equipped with bypass square tube 5; can play the effect of preheating cover plate (not shown in FIG.); reduce the impact of the cold and hot temperature difference to radiator core body as far as possible when the compressor cold start-up, thereby greatly protected the heat radiation core body.In addition, the effect of bypass square tube 5, first flow through oil in bypass square tube 5, simultaneously can also and two square openings 9 of bypass square tube 5 between play the effect of a heat exchange, a just cooling part, improved radiating effect greatly before oil does not pass through radiator.
The present invention effectively prevents from concentrating because of the thermal shock core body internal channel stress that causes dispelling the heat, and finally causes the spalling of core body internal channel, product leakage.Good heat dissipation effect.
The present invention can be by following test method: performance test (wind tunnel test), vibration test, thermal fatigue test, bursting test.
Above description is explanation of the invention, is not that limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification to the restriction of invention.
