Description
Technical field
The present invention relates to a kind of cooler, be specifically related to a kind of hydraulic oil cooler.
Background technique
At present in the industrial production, various hydraulic equipment can be used, hydraulic equipment is that power carrys out actuate actuators work usually with pressure oil, the friction that pressure oil continues acting and hydraulic equipment parts causes hydraulic fluid temperature to rise, and the temperature of hydraulic oil directly can affect the operating mode of hydraulic equipment, analysis of hydraulic oil overheat gently then affects the working efficiency of equipment, and more serious some more accurate hydraulic equipment that also likely makes quits work, such as numerically controlled lathe, numerical control machining center etc.Especially in summer, the higher hydraulic fluid temperature of temperature can be easy to too high.
Summary of the invention
The problem that the present invention is directed to above-mentioned prior art provides the hydraulic oil cooler of simple, the real Ying Xingqiang of a kind of structure, low cost of manufacture.
The technical solution used in the present invention is: a kind of hydraulic oil cooler, comprise housing, heat dissipating pipe is provided with in housing, the filler opening of heat dissipating pipe and oil outlet are located at outside housing, heat dissipating pipe is serially connected on the normal pressure oil circuit of hydraulic equipment, housing is provided with fan, and housing is provided with radiator window on the direction of fan blowing.Hydraulic oil is through heat dissipating pipe, and fan turns is dried, and makes heat dissipating pipe superficial air accelerate flowing, takes away heat, reach the object reducing hydraulic fluid temperature.
Preferably, described heat dissipating pipe is snakelike.Heat dissipating pipe is set as the snakelike heat diffusion area increasing heat dissipating pipe in housing, improves radiating efficiency.
With improvement, hydraulic oil cooler of the present invention also comprises the controller controlling fan turns and the temperature transducer being located at heat dissipating pipe filler opening place, and temperature transducer is electrically connected with controller, and the coil of fan is electrically connected with controller.Detected the temperature of filler opening hydraulic oil by temperature transducer, and by signal transmission to controller, controller is according to the rotating speed of the SC sigmal control fan received and start and stop.Adopt the technical program can start fan when high oil temperature or the maximum oil temperature close to normal work, instead of allow fan rotate always, save the energy.
With improvement, described heat dissipating pipe outer wall is provided with radiating fin, and radiating fin is parallel with the direction that fan is dried.The technical program is adopted more to be conducive to heat radiation.
Preferably, the cross section on the vertical fan blowing direction of described radiating fin is snakelike.Adopt the technical program can increase the heat diffusion area of radiating fin, improve radiating efficiency.
Preferably, described radiating fin is ring and arranges perpendicular to heat dissipating pipe central axis, and arrange interval 0.5cm-2cm, the width of radiating fin annulus is greater than 1/3 heat dissipating pipe diameter, is less than the heat dissipating pipe diameter of 1.5 times.During through facts have proved that radiating fin meets the feature of the technical program for a long time, radiating effect is best.
Preferably, the width of described radiating fin equals the diameter of heat dissipating pipe.
Preferably, described heat dissipating pipe is copper pipe.The heat-conducting effect of copper is relatively good, adopts copper heat dissipating pipe to improve radiating efficiency.
The invention has the beneficial effects as follows: hydraulic oil cooler structure of the present invention is simple, and fabricating cost is low, and radiating efficiency is high, practical, and energy-conserving and environment-protective.
