"Device for cooling media"

The invention relates to a device for cooling media, in which the medium flows through pipes which, on the one hand, distribute the flow of a distribution box Intercooling liquid, e.g. B. water, by gravity, on the other hand the air flow caused by a fan are exposed, with the intermediate cooling liquid in the air stream is evaporated.

One of the main difficulties involved in achieving a Satisfactory performance must be overcome with this device consists in that to be overcome by the air flow Resistance that a force to be provided by the fan requires, which is greater, the greater this resistance.

The object of the invention is to propose a device that high cooling performance and low resistance of the

Having air flow. To this end, the invention proposes a system of graduated distributors for the intermediate liquid before and between each two successive stages a tube bundle which is arranged so that it wets and reduces the airflow resistance to the highest possible level.

This task is achieved in that each tube consists of different horizontal, in one and the same vertical plane at a distance from each other, via pipe bends in Zigzag interconnected pipe sections consists that. the vertical planes are parallel to each other, that each pipe section of the various pipes together form a pipe section bundle, that the pipes to each other so are offset that the air in each horizontal plane is released a considerable flow cross-section, and that the distribution box for the cooling liquid is inserted between two or two successive tube bundles.

Each distribution box can be made up of a frame forming the distribution tabs exist, and the highest and lowest sections of a pipe can be connected to a manifold and to a Be connected to collectors.

The device also usually has the cooling water distribution parts at the top and below the parts for reassembly

would take the water, using the air blowers either can be arranged above or below.

The invention will now be described in more detail with reference to the accompanying drawing, which shows an example of an embodiment represents a cooling device according to the invention. Show it:

1 shows a longitudinal section of the device,

Fig. 2 partially shows a cross section along line H-II of Fig. 1,

Fig. 3 individual images, the two types of arrangement and 4- represent the tube sections of a tube bundle.

The arrangement in its entirety consists of a housing 1, in the upper part of which an intermediate liquid flows into a common one Trough or pipe 2 introduced and via distribution pipes 3 is distributed on distribution trays 4-, from which it overflows flows down onto the parts of a distributor 5. The ones about the Liquid distributed over the entire horizontal surface of the arrangement then flows in droplet form through various layers lying on top of one another Distribution assemblies 6 and the intermediate tube bundles 22, 23 »24, through to collected at the foot of the assembly in a basin to become. The intermediate liquid is taken up again by a motor pump unit and fed into the upper part of the device, namely in the distribution trough 2, promoted. A motor fan 28 conveys air in countercurrent to the intermediate liquid.

The air introduced through a ring is diverted by blades 9, flows upwards and escapes from the device at their head 10. The fan can be arranged either at the foot or at the head of the device and under pressure (compression) or negative pressure (suction) work.

Droplet separators 11 are arranged between the housing and the ring in order to avoid water on the blower unit is thrown. Likewise, the droplet cutters 12 on the head of the device prevent droplets from being entrained in the air will.

The liquid or gaseous medium to be cooled or liquefied is finally fed into the device through the collector and the sub-manifold 14- is introduced and flows within the pipes 7 to cooled or liquefied by the partial collector 15 and. the common collector 16 to escape.

The tubes 7 are on their surface in contact with the liquid flowing down in droplet form, which cools the brings liquid flowing within the tubes.

According to the invention, each tube 7 lies in a vertical plane; all of the planes are parallel to one another and each pipe has a horizontal one below each distributor 5, in

the longitudinally extending section 17 »a pipe bend 18, a second, lying under the first section 17 section 19 and a pipe bend 20, which this with the horizontal, under the following manifold 6 ^, lying section 21 connects.

Also according to the invention, the identical pipes are a partial representative in groups with a slight mutual height offset assigned in such a way that they are between two consecutive

The tubes thus form horizontal tube bundles 22, 23, 24, 25 »the sections of which are staggered to one another in a staggered arrangement so that the air flow in a horizontal plane is only limited in number (two in one and the same horizontal cross section in the example shown ) of pipe sections that leave a considerable cross-section free for the upstream air flow.

^T he by one of the distributor 5 or 6 ^ - 6, as a droplet distributed liquid drops to the pipes down, is atomized and completely wetted the outer wall. The air flows upwards, completely and effectively surrounding the skin adhering to the tubes.

The tubes can be arranged differently to one another, Tube bundle

e.g., as in Pig. Shown 2 and 3, the tubes, from two successive pipe groups held on adjacent sub-manifolds 14 either in opposite directions Direction be graded in such a way that the tube bundles viewed in the front view together form a number of V, the sub-manifold itself having opposite inclinations have, or have the same inclination, the sub-manifolds 14 then have parallel inclinations (FIG. 4).
