Abstract
The utility model relates to a high-efficient machine oil cooler comprises upper and lower grease chamber, radiating fin between the upper and lower grease chamber and a plurality of cooling tubes that run through radiating fin, and its key feature is that the cooling tube adopts the pipe, sets up the vortex ring in the pipe, has improved compressive strength as the cooling tube with the pipe, has improved the radiating efficiency through the vortex ring, the utility model is suitable for a cooling of high pressure, large-traffic engine, engineering machine tool or lathe hydraulic oil or other medium.
Description
The utility model relates to field of cooling, relates in particular to a kind of efficient engine oil cooler.
Motor, engineering machinery and some lathes all have the high temperature hydraulic oil of high pressure, big flow to cool off by cooler and fan in working order down and recycle, but existing machine oil cooler does not often reach 70% standard cooling effectiveness, for example a kind of lower oil chamber that comprises, the cooler that spaced layer by layer radiating fin and some rectangular-shaped heat dissipating pipes that runs through radiating fin and communicate with last lower oil chamber constitute between the last lower oil chamber, this cooler is under the effect of high pressure oil, and rectangular-shaped heat dissipating pipe often occurs breaking leakage of oil and can't work.
The purpose of this utility model provides a kind of heat dissipating pipe to be difficult for breaking at the problem of above-mentioned existence, the efficient engine oil cooler that radiating efficiency is high.
The purpose of this utility model passes to down technological scheme and realizes, a kind of efficient engine oil cooler, comprise upper chamber with filler opening and oil outlet, lower oil chamber, spaced layer by layer radiating fin between the last lower oil chamber, run through partition panel constitutes in radiating fin and last lower oil chamber sealing and fixing and some heat dissipating pipes that communicate and the last lower oil chamber heat dissipating pipe and string communicate, it is characterized in that heat dissipating pipe is the garden pipe, is provided with helical flow-disturbing ring in the pipe of garden; The ring outer wall of flow-disturbing ring touches mutually with inner tube wall; Flow-disturbing ring and garden Guan Tongchang, the flow-disturbing ring turns to the rotation of unitary piece of metal thin strip.
The utility model is by managing rectangular-shaped heat dissipating pipe design employing garden, increased compressive resistance intensity, thereby the garden pipe is difficult for breaking under same oil pressure, after considering that simultaneously employing garden pipe is as heat dissipating pipe, particularly when diameter is managed in the garden greater than 10mm, machine oil very easily produces vortex phenomenon in flow process, promptly slow along the machine oil flow velocity of inner tube wall, middle machine oil flow velocity is fast, middle machine oil flows out without heat exchange fully, greatly reduce radiating effect, thereby in pipe, be provided with helical flow-disturbing ring, eliminated vortex phenomenon fully, and proper extension the flow path of middle oil, the time and the condition of heat exchange have been increased, increased radiating efficiency greatly, not only can reach existing radiating efficiency, also can improve more than 10 percentage points, the utility model has realized that heat dissipating pipe improves compressive resistance intensity, is difficult for breaking and improves the purpose of radiating efficiency.
Accompanying drawing 1 is the utility model master TV structure schematic representation;
Accompanying drawing 3 is a heat dissipating pipe fin monolithic schematic top plan view in the utility model;
In the accompanying drawing: 1 filler opening, 2 heat dissipating pipes, 3 oil outlets, 4 upper chamber, 5 flow-disturbing rings, 6 lower oil chamber, 7 radiating fins, 8 partition panels.
Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is by upper chamber 4, lower oil chamber 6, last lower oil chamber 4, spaced layer by layer radiating fin 7 between 6, the some gardens pipe heat dissipating pipe 2 that runs through radiating fin 7 and upper chamber 4 and lower oil chamber's 6 sealing and fixing and communicate constitutes, filler opening 1 and oil outlet 3 are arranged on the upper chamber 4, in the upper chamber 4, be provided with partition panel 8 in the lower oil chamber 6, the also string that partition panel 8 has constituted garden pipe heat dissipating pipe 2 communicates, be provided with the flow-disturbing ring 5 that rotates coiling with the unitary piece of metal thin strip in the every garden pipe heat dissipating pipe 2, flow-disturbing ring 5 is long together with garden pipe heat dissipating pipe 2, the ring outer wall of flow-disturbing ring 5 touches mutually with heat dissipating pipe 2 inwalls, in the work, High Temperature High Pressure machine oil pumps into through filler opening, under the partition of the partition panel 8 in upper chamber 4, machine oil only has been full of the part upper chamber 4 that is cut off, and enter each garden of shape in parallel pipe heat dissipating pipe 2, under the effect of flow-disturbing ring 5, high temperature oil both flowed along inner tube wall, and the while is along the inside and outside wall rotational flow of flow-disturbing ring 5, the machine oil that flows along the garden inner tube wall has sufficient heat exchange condition, the machine oil that flow along flow-disturbing ring 5 are owing to prolonged flow path, increased the flowing time in pipe accordingly, also under certain flowing velocity, along angle of rotation and inner tube wall collision, thereby had the time and a condition of sufficient heat exchange, final cooled machine oil through oil outlet 3 to each operation point.The utility model adopts the garden pipe to improve the compressive resistance intensity of heat dissipating pipe as heat dissipating pipe, the flow-disturbing ring is set has improved radiating efficiency.
