In general, hydraulic oil is used in the use of the power pack. As the temperature of the hydraulic oil rises due to continuous use, a separate cooling device is required.
In particular, when the power pack is driven for a predetermined time in the summer, the hydraulic oil is heated and the efficiency of the power pack sharply decreases. To solve this problem, a separate cooling device is used.
Here, in order to cool the hydraulic oil, the hydraulic oil is circulated and the hydraulic oil is cooled through heat exchange with the outside. In order to cool the hydraulic oil, air cooling type and water cooling type cooling are mainly used.
In the case of the air cooling type, the hydraulic oil is cooled through heat exchange with the air, and the structure is simple and the cost is low, but the cooling efficiency is very low.
Especially, since hydraulic oil can not be cooled in a short time, there are many restrictions on use.
On the other hand, in the case of the water-cooling type cooling device, the cooling efficiency is relatively higher than that of the above-described air-cooling type, but it is complicated in structure due to its characteristics, and its volume and weight are increased.
Particularly, in the case of water-cooled type, separate seawater or water supply device and cooler hose are required, and it is not easy to install and move due to volume.
In order to solve such a problem, it is urgent to develop a cooling device which is simpler and has excellent cooling efficiency.
An object of the present invention is to solve the problem of a conventional portable cooling apparatus for a power pack. The present invention relates to a power pack capable of circulating hydraulic oil having a raised temperature and connected to a power pack, and capable of cooling hydraulic oil by water- And a portable cooling device for use.

The connection portion may include a tube sheet having a recessed groove formed on one surface thereof and having a plurality of communication holes formed on the recessed groove to connect both ends of the cooling tube to each other, A connector for forming a flow space together with the inlet and the outlet port and on the depressed groove to divide the flow space into a plurality of divided spaces, at least a part of each of the divided spaces being independently communicated with the inlet and the outlet And a dividing means for dividing the image.
Here, the dividing means may be formed integrally with any one of the connector and the tube sheet.
The protection unit may include a first fixing unit connected to the connection unit and surrounding the first fixing unit, a second fixing unit spaced apart from the first fixing unit along the longitudinal direction of the cooling tube, And a stationary shaft which penetrates and fixes the first fixing portion and the second fixing portion, respectively.
The protection unit may further include a separate rectangular support part protruding from the first fixing part and the second fixing part to prevent the circulation unit from moving unintentionally due to an external force. have.
The protection unit may further include at least one protective cover that is disposed between the first fixing unit and the second fixing unit and surrounds the cooling tube.
Further, the cooling tube may be formed of at least one of copper, nickel, copper, brass or stainless steel.
In order to solve the above problems, the present invention has the following effects.
First, the cooling device according to the present invention includes a protection unit for preventing the circulation unit and the circulation unit through which the hydraulic oil circulates from being damaged in the seawater or water while being flooded, and the hydraulic oil is heat- So that there is an advantage that the hydraulic oil can be cooled by a water-cooled method without a separate cooling facility.
Second, since the protection unit is provided with a separate rectangular support, there is an advantage that the circulation unit can be prevented from moving or rolling unintentionally and can be stably fixed.
