Abstract

The utility model discloses a simple tubular oil-water cooler. The simple tubular oil-water cooler comprises an inner tube and outer tubes, wherein the inner tube is formed by bending a tube to be snake-shaped; one end of the inner tube is an oil inlet joint; the other end of the inner tube is an oil return joint; the outer tubes are sleeved on the straight tube section of the inner tube; a water inlet joint is arranged on the outer tube at one side; a water return joint is arranged on the outer tube at the other side; and the outer tubes are communicated by a branch tube. The oil-water cooler disclosed by the utility model adopts a structure that the outer seamless steel tubes are sleeved on the inner tube which is formed by directly bending a straight tube, is good in cooling effect, simple to produce, few in working procedures, and low in labour intensity, thus realizing low cost and low rejection rate, as well as is few in welding points, strong in corrosion-resistant capacity, and not easy to occur leakage faults; meanwhile, the oil-water cooler disclosed by the utility model is low in requirements on the conditions of water quality, pressure, temperature difference, installation and the like, acts a reliable guarantee effect on the safe and stable running of equipment, and can be widely recommended and used for metallurgical enterprises and similar enterprises, and various small hydraulic systems with bad working conditions.

Description

A kind of simple tubular type oil-water cooler

Technical field

The utility model belongs to oil-water cooler technical field, specifically a kind of simple tubular type oil-water cooler.

Background technology

Oil-water cooler heat-transfer pipe adopts copper tube to roll out radiating fin, and heat exchange area is large, and small product size is little, lightweight, is specially adapted to the cooling of the low and more clean fluid of viscosity; Be widely used in the industries such as plastics machinery, hydraulic test, air compressor machine, the cunning system of thin oil, fluid-flywheel clutch, electric device.But current oil-water cooler purchase cost is high, procurement cycle long, it is large to detect maintenance difficulties, simultaneously because cooling water system user is many, pressure/instability of flow, enter return water temperature variation greatly, the not high factor of the actual water quality of user causes hydraulic system plate type heat exchanger operation troubles many, inside, outside leakage etc. easily occur, and the simultaneous faults processing time is long.

Utility model content

Technical problem to be solved in the utility model be for oil-water cooler of the prior art, easily there is the problem of the faults such as inside, outside leakages and a kind of compact conformation, good cooling results be provided, be difficult for generation leakage failure, simple tubular type oil-water cooler that operational effect is good.

For solving technical problem of the present utility model, adopt following technical scheme:

A kind of simple tubular type oil-water cooler, comprise inner and outer tubes, described inner tube is to be bent into snakelike shape by a pipe, one end of described inner tube is fuel inlet fitting, the other end is back leakage connection, on the straight length of described inner tube, is set with outer tube, on a described side outer tube, water supply connector is set, on opposite side outer tube, backwater joint is set, between described outer tube, by arm, is communicated with.

Described inner tube is stainless steel tube.

Described outer tube is seamless carbon steel tube.

The outer tube structure that is set with seamless steel pipe in the inner tube that the utility model oil-water cooler adopts a direct bending of straight tube to form, cooling effect is good, makes simple and operation is few, thereby labour intensity is low, to realize cost low, percent defective is low; Pad is few, and corrosion resistance is strong, is difficult for occurring leakage failure; The utility model is not high to conditional requests such as water quality, pressure, the temperature difference, installations simultaneously, the safety of equipment, stable operation have been played to reliable guaranteeing role, and extensively recommendation is in the poor small-sized hydraulic system of the similar and all kinds of working condition of smelter.Table 1 is the utility model determination data record sheet.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in Figure 1, a kind of simple tubular type oil-water cooler, comprises inner tube 2 and outer tube 1, and inner tube 2 is to be bent into snakelike shape by a stainless steel tube, and one end of inner tube 2 is fuel inlet fitting 4, and the other end is back leakage connection 5, passes into hydraulic medium oil during use.On the straight length of inner tube 2, be set with on outer tube 1, the one side outer tube 1 of seamless carbon steel tube and be installed into water swivel 6, on opposite side outer tube 1, install back water swivel, pass into cooling water medium during use, 1 of outer tube is communicated with by arm 3.

The utility model can singly be organized multilayer series connection and many group series connection, according to on-site actual situations, can be combined, and can meet the cooling of any small-sized hydraulic system.Installing space is also unrestricted, by concrete space, scene, is determined, and can make somebody a mere figurehead or be placed on the position apart from hydraulic system compare Yuan, by high-pressure hose, connects.
