Abstract
The utility model discloses an oil cooler. A heat exchange pipe is arranged inside a shell of the oil cooler. Surface of pipe wall of the heat exchange pipe is curved or both curved and beveled. A concave portion is arranged on inner pipe wall of the heat exchange pipe. A convex portion is arranged on outer pipe wall. According to the oil cooler, the heat exchange pipe is capable of enlarging heat exchange area. The smooth concave portion of the inner pipe wall of the heat exchange pipe has a certain resistance force to oil so that flow rate of the oil is slowed and no strong resistance force is imposed on the oil. The convex portion of the outer pipe wall is capable of increasing stir of outside fluid and improving heat exchange effect.
Description
Technical field:
The utility model relates to a kind of cooler, relates in particular to a kind of oil cooler.
Background technology:
The oil cooler heat-transfer pipe adopts copper tube to roll out radiating fin, and heat exchange area is large, and small product size is little, and is lightweight.Oil cooler is applicable to the low and cooling of the fluid of cleaning of viscosity; Oil cooler can be applicable to the industries such as plastics machinery, hydraulic test, air compressor machine, the cunning system of thin oil, fluid-flywheel clutch, electric device.
But there is following shortcoming in the oil cooler of said structure in the use procedure of reality: 1. the oily passage of heat-transfer pipe is straight channel, and the speed that oil passes through is fast, from but heat exchange amount is lower, cooling effect is relatively poor.2. in order to make heat transfer effect better, generally adopt the good material of heat exchange effect, increased the cost input.
The utility model content:
In order to address the above problem, it is a kind of simple in structure that the utility model provides, the oil cooler of good effect of heat exchange.
The technical solution of the utility model is: oil cooler, in the housing of this oil cooler, heat exchanger tube is installed, and the tube wall of described heat exchanger tube is the combination on curved surface or curved surface and inclined-plane.
The inner tubal wall of described heat exchanger tube is provided with recess.
The outer tube wall of described heat exchanger tube is provided with protuberance.
The smoothness of described recess is greater than the smoothness of protuberance.
The beneficial effects of the utility model are: heat exchanger tube of the present utility model, increased heat exchange area, improved heat transfer effect, the heat exchanger tube inner tubal wall has level and smooth recess, and oil is had certain resistance, and oily flow velocity has slowed down, and don't can larger resistance be arranged to oil, the protuberance of outer tube wall has strengthened the disturbance to external fluid, has improved heat transfer effect.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of heat exchanger tube of the present utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, 2, oil cooler is equipped with heat exchanger tube 100 in the housing 200 of this oil cooler, and the tube wall of heat exchanger tube 100 is the combination on curved surface or curved surface and inclined-plane.The inner tubal wall of heat exchanger tube is provided with recess 120, and outer tube wall is provided with protuberance 110.The smoothness of recess 120 is greater than the smoothness of protuberance 110.
Heat exchanger tube of the present utility model, increased heat exchange area, improved heat transfer effect, the heat exchanger tube inner tubal wall has level and smooth recess, and oil is had certain resistance, and oily flow velocity has slowed down, and don't can larger resistance be arranged to oil, the protuberance of outer tube wall has strengthened the disturbance to external fluid, has improved heat transfer effect.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
