Abstract

The utility model discloses a spiral cooler, which comprises a box body, a sealing cover, a spiral oil pipe and a water return pipe, wherein the sealing cover is arranged at the top of the box body, and a water inlet pipe is arranged in the sealing cover in a penetrating way; the right lower side of the spiral oil pipe is connected with an oil inlet pipe, and the left upper side of the spiral oil pipe is connected with an oil return pipe. The utility model adopts spiral oil pipe inside and gland outside, when the oil pipe leaks, the leakage point can be easily found for maintenance; when the cooling effect is poor, the sealing cover can be opened to clean the interior.

Description

Spiral cooler

Technical Field

The utility model relates to a cooler especially relates to a spiral cooler.

Background

At present, a plate cooler is adopted for reducing oil temperature in a hydraulic system, the plate cooler is a novel efficient heat exchanger formed by stacking a series of metal sheets with certain corrugated shapes, thin rectangular channels are formed among various plates, heat exchange is carried out through half sheets, and the heat transfer coefficient of the plate cooler is much higher than that of a conventional device under the conditions of the same flow resistance and the same pump power consumption. However, since the plate cooler is composed of a plurality of plates, the sealing performance is poor, leakage is easy, and the gasket needs to be replaced frequently, which is troublesome. In the use, a certain leakage can lead to the oil tank to intake, and multilayer slab structure is difficult to investigate the leakage point, and difficult maintenance and change rate are high. In addition, after the cooler operates for a period of time, deposits in the aqueous medium can generate a scale layer on the heat exchange surface, the scale layer can obviously reduce the heat transfer rate and has certain influence on the cooling effect, and the plate cooler needs to be detached and cleaned due to the fact that the number of the plates is large when the plates are scaled, and the mechanical operation needs to be stopped during cleaning to influence the production efficiency.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing an easy abluent spiral cooler of maintenance.

The technical scheme is as follows: the spiral cooler comprises a box body, a sealing cover, a spiral oil pipe and a water return pipe, wherein the sealing cover is arranged at the top of the box body, and a water inlet pipe is arranged in the sealing cover in a penetrating way; the right lower side of spiral oil pipe is connected with into oil pipe, and the upper left side is connected with back oil pipe.

At the initial operation stage of the cooler, an oil way in the spiral oil pipe can be contacted with cooling water within the shortest time from bottom to top, and the cooling operation is started; and the water inlet pipe is arranged at the top of the spiral oil pipe, and can also play a role in spray cooling on the spiral oil pipe.

Preferably, the water outlet of the water inlet pipe is a bell mouth. The horn mouth can reduce rivers and to spiral oil pipe's impact, and can disperse rivers optimization cooling effect.

Preferably, the spiral oil pipe is detachable. The spiral oil pipe is easy to replace.

Preferably, the water inlet pipe, the water return pipe, the oil inlet pipe and the oil return pipe are all provided with control valves. The control valve closes the pipeline to facilitate the maintenance and cleaning of the cooler.

Preferably, a sealing gasket is arranged on the inner side of the sealing cover.

Has the advantages that: compared with the prior art, the utility model, have following advantage: 1. the device adopts a spiral oil pipe inside and a gland outside, so that when the oil pipe leaks, a leakage point can be quickly found for maintenance; 2. the device has simple structure, is easy to wash and keeps the cooling effect.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

Spiral cooler include box, closing cap 3, spiral oil pipe 4, wet return 7. The sealing cover 3 is arranged at the top of the box body through a bolt, the sealing cover 3 is penetratingly provided with a water inlet pipe 1, and a water outlet 2 of the water inlet pipe 1 is a bell mouth; the spiral oil pipe 4 is detachable, the right lower part of the spiral oil pipe 4 is connected with an oil inlet pipe 6 through a joint, the left upper part of the spiral oil pipe 4 is connected with an oil return pipe 8 through a joint, and the water return pipe is arranged on the left side of the box body; the water inlet pipe 1, the water return pipe 7, the oil inlet pipe 6 and the oil return pipe 8 are all provided with ball valves, and the inner side of the upper sealing cover 3 is provided with a sealing gasket 9.

Spiral cooler begins work, advances oil pipe and inlet tube and begins the feeding, and oil circuit is by supreme operation down in the spiral oil pipe, and the cooling water sprays from spiral oil pipe top, sprays the cooling to spiral oil pipe, and the cooling water level rises in the box, and spiral oil pipe bottom begins to soak in the cooling water in the short time.

Preferably, the cooler is filled with cooling water, and then the oil inlet pipe ball valve is opened.

When the oil pipe leaks, water is stopped from entering through the ball valve, and a leakage point can be found by opening the gland easily for maintenance; when the cooling effect is deteriorated along with the time, the gland 3 can be opened to clean the interior of the cooler; when the spiral oil pipe 4 has more leakage points, the new spiral oil pipe 4 can be directly replaced.
