Cooling water circuit, a refrigerant circuit and a cold water circuit, which is a technically complex and costly system.

The main object of the invention is to make the system thereby to simplify that only a single circuit is provided.

The conventional and common ones listed below Processes for heat dissipation are particularly cost-intensive in terms of economy and technical feasibility or complicated solutions:

- Heat dissipation with cooling water from the pipe network of the pit and return to the general aqueduct,

- Heat dissipation with cooling water from above ground in high pressure condensers,

- Heat dissipation via ducts with high pressure heat exchangers,

- Heat dissipation through an open water circuit in the shaft using an appropriate fan,

- heat dissipation through an underground cooling tower,

- Cooling water cooler installed underground with a closed • cooling water circuit.

Since the dissipation of the heat generated in the condenser with conventional This is especially true for refrigeration machines for air conditioning Pits because of the lack or the high cost of cooling water, the long distances and the complex facilities result in particular difficulties for cooling water recooling.

Other disadvantages of conventional pit air conditioning are

stand in the fact that with de r_ arrangement: of individual coolers in the strut entrance

--ST- 2197-98

people working in the vicinity of the cooler are cold, while at a greater distance a cooling effect can hardly be felt;

that several smaller cooling units complicate the daily mining operation considerably, because the cooler and lines daily accordingly must also be laid;

that conventional coolers are easy to damage and therefore sensitive are;

that the coolers are difficult to install or accommodate because of their weight and dimensions;

that conventional finned coolers quickly become dirty and completely clogged due to the large amount of dust; that when using refrigeration machines, the dissipation of the heat generated in the condenser is a particular problem; that when installing refrigeration machines in sight the problems on the cold water side, with regard to the condensation water, etc. " raise;

that in some systems the cooling tower or an equivalent. Facility must be installed underground and thus considerable Cost of accommodation and space requirements;

That the air throughput and thus the building volume must be greater because the physical condition of the weather is worse than the air condition over days;

that the cooling water is heavily polluted because the moving weather usually contains a lot of dust, so that it is filtered must (risk of contamination of the waterway in the condenser); that the weather contains a lot of water vapor because the Weather absorbs the heat preferentially as latent heat, with the water vapor in the shaft on the way

condenses to the surface of the day, resulting in a very wet pull-out shaft has the consequence.

Also the arrangement of the weather cooler and the associated cooling machine underground causes difficulties. There is a need to keep the weather cooler as close as possible to the workplace to set up. Usually z. B. the chillers both directly on the weather cooler on site, as well as face coolers at the beginning of the mining route in a central location near the shafts and finally also above ground. Of the The location of the actual cooling device (heat exchanger) therefore poses a problem with steadily progressing degradation.

The coolers can either be arranged freely and are made using the thermal or the possibly prevailing Air flow, or they are arranged in a ventilation duct and are ventilated by a warm air flow flows through.

In order to overcome the disadvantages of the known systems, the invention is still based on the objects of designing the heat transfer system in such a way that a reliable, sufficient and as uniform as possible cooling can be carried out with as little effort as possible, the system should also offer the possibility of a quick and variable installation, so that the cooling system without hindering the dismantling activity can be carried along the entire route to the dismantling site. After all, the system should also offer the possibility offer to provide an increased cooling capacity depending on requirements and local conditions.

So it will the process of evaporation and condensation of a liquid at a constant temperature is used to transport heat. That at the Condensate deposited on the cooling surface flows using its surface tension from the cooling to the heating zone in a Chapter structure door back.

Since the previously usual separate units evaporator in the heat pipe and condenser are combined in one unit, d. H. because the heat pipe is basically a miniature version of a hermetically sealed evaporation and condensation device, the so-called refrigerant and cold water circuits are omitted, only the cooling water circuit remains, which is a closed circuit via a recooling, via a or several heat exchangers for washing cheek heating or the like.

Deviating from the requirement of general air-conditioning technology to create a comfortable climate, air-conditioning technology in mining is mostly limited to creating "bearable" conditions. The differences between the generally applicable comfort zone and the climatic conditions occurring in pits are very large. The mean climatic conditions in the face are between
between 60 and 75%.

Temperatures between 28 and 30 C and at the relative humidity

The ability of the heat pipe to handle large amounts of heat even with relatively small temperature differences, makes it possible by the system according to the invention with simple means in an ideal way a uniform temperature control in the To create a pit, deviating from the simplified, schematic representation of FIG. 1, the cooling water supply line 18 to the heat pipes and the cooling water return line 20 from the heat pipes run parallel to one another, in such a way that that any number of cooling elements with one or more parallel-connected heat pipes over the entire too distributed in the cooling pit area and, if desired, concentrated for increased cooling capacity between the cooling water supply and the cooling water return line 18 and 20 can be switched on, so that all heat pipes of the entire system are connected in parallel to each other.

In the simplest design, FIGS. 4 and 5 show two cooling elements 22 and 24 suitable for the system according to the invention in the form of simple cylindrical heat pipes, each of which is traversed by a cooling water line 26 and 28, respectively in the case of the heat pipe 22, the cooling water line 26 is concentric with the cylindrical outer container 30 of the heat pipe and in the case of the heat pipe 28 is arranged eccentrically to the cylindrical outer container 32, if there are special conditions at the place of use Make the design appear more advantageous. Between the tubular cooling water lines 26 and 28 and the outer containers 30 and 32, the capillary structure 34 and 36, respectively, extends in FIG the area of which the heat pipe is filled with an easily evaporating liquid that evaporates on the outer container and is reflected as condensate on the cooling water line 26 or 28 and through the capillary structure back to the inner wall

2197-98

of the outer container 30 or 32 is returned. On the front sides of the outer container, the cooling water lines 26 and 28 each open into inlet supports 26a and 28a and outlet nozzles 26b and 28b, which are provided with shut-off valves 26x and 28x and 26y and 28y, respectively, so that each heat pipe included in the system can be switched off from the cooling water circuit at any time, be it because this is desired for temperature control or is necessary because of a repair.

Fig. 2 shows a section from a first embodiment of the system according to the invention, in which the individual Cooling elements, which in this embodiment have a total of 38 are denoted, are joined to one another in the form of strands. The cooling water supply lines run on both sides of the cooling element strand 18 and the cooling water return line 20, to which each individual cooling element 38 is connected with its inlet port 26a and its outlet port 26b, respectively. The core of everyone this cooling element 38 forms, for example, a heat pipe corresponding to the cooling element 22 explained each have a coupling base 40, with both coupling bases 40 are of the same design but are offset from one another by 180 about the longitudinal axis of the cooling element, so that due to the special shape of the coupling base 40, which can be clearly seen above all in FIG. 6, by joining several cooling elements 40 results in a straight cooling strand.

The coupling base 40 is designed like a housing and has a square cross-section transversely to the longitudinal axis of the heat pipe on, which is preferably inscribed on the outer circumference of the heat pipe. The adjacent cooling element to be coupled facing separation surface 42 extends at an angle of 45 to

709844/0097 - ¹ ^

2197-98

Heat pipe axis, so that taking into account the space requirements for the inlet and outlet to be led out to the side in the direction of the cooling water supply or cooling water return line 18 and 20, respectively Output connector 26a or 26b an extremely compact design of the coupling base 40 and thus per unit length of the cooling element strand results in a particularly high cooling capacity. Because it forms an angle of 45 ° with respect to the longitudinal axis of the heat pipe The coupling base 40 is given a narrow and separating surface 42 a wide rectangular side surface 44 or 46, the cooling water nozzles 26a and 26b through the wide side surface 46 are led to the outside, which is why the cooling water nozzles 26a and 26b themselves are angled by 90.

On the two rectangular side surfaces 44 and 46, the elements of tendon connectors are arranged allow two adjacent cooling elements 38 a fixed, but detachable connection by a simple handle. It can, for example, on the narrow rectangular surfaces 44, respectively

Loop-like elements 45 and on the wide rectangular surfaces 46, respectively Be attached toggle-like clamping lever 47 of a known type, as shown in FiR. 6 can be seen.

To the cooling element strand the respective course of the to be cooled To be able to adapt the route, intermediate elements are provided, which are shown in FIGS. 6 and 7a to 7d as a selection of many possible Variants are shown. As can best be seen from Fig. 6, such an intermediate element has two of each other opposite ends each have a coupling base 40, which corresponds to the coupling base of the cooling elements 38, so that the intermediate element between two cooling elements, between two further intermediate elements or between an intermediate element

-IST- 2197-98

and a cooling element 38 can be inserted. In a particularly expedient Embodiment, the intermediate element has the same Cross-section like the coupling base 40 and is like this housing-like formed, as can be clearly seen in the intermediate element 48 shown in FIG. 6. This intermediate element 48 also serves to change the direction of the cooling element strand after its two separating surfaces 42a and 42b have moved 90 degrees to their normal position with straight strands against each other are offset.

7a to 7d show ground plans of intermediate elements 48, 48b, 48c and 48d inserted between two adjoining elements Cooling elements 38 and intended for different angles of deflection from 90 to 45 and 30 to 15. While these intermediate elements only angular deviations of the cooling element strand in one Allow level, the intermediate elements can also be designed such that a change in direction of the cooling element strand in the three-dimensional space is made possible, which is only a different mutual position of the two separating surfaces 42a and 42b one Requires intermediate element. Finally, it is also possible to use the two separating surfaces and the two coupling bases provided with these separating surfaces of an intermediate element against each other adjustable to be arranged on an intermediate element, for example In a manner not shown, both coupling sockets can be rotatable about a cylindrical connecting piece or else are connected to one another via a lockable joint. Since the intermediate element has no function whatsoever for conducting a cooling water or air flow, but only as a mechanical connecting element between adjacent cooling elements is used, its construction is hardly subject to any restriction as long as the coupling device with that of the cooling elements matches. 709844/0097 -16-

Fig. 3 shows another embodiment of a cooling element strand, which is shown schematically as a weather channel in a shaft, which is designated with 50 and from which two tunnels 52 and 54 go out. The structure of the cooling element strand can be seen more clearly from FIG. 3a.

As in the first embodiment, the cooling water supply lines run 18 and the cooling water return line 20 in parallel, each individual cooling element designated here by 56 again having a Inlet connection 68 is connected to the cooling water supply line 18 and via an output connection 70 to the cooling water return line 20 is. Each cooling element 56 contains at least one heat pipe 76, the shape of which, however, differs from the designs described above, even if the functionality is the same. The construction of the heat pipe used here is then illustrated with reference to FIG. 8 to 11 explained in more detail.

Each cooling element 56 has a jacket in the form of a housing section 74, which is part of a flow channel for represents a weather stream to be cooled. The inlet and outlet nozzles are led out laterally from the housing section 74, the heat pipe 76, however, is in the interior of the housing section 74 arranged and is flowed against by the weather stream. The housing section 74 of the cooling element is connected upstream 56 a housing section 78, in which a only schematically shown Air filter 80 is arranged. Upstream, finally, a housing section 82 follows, which is attached to its from Air filter housing section 78 is closed facing away from the side, but provided with air inlet openings 84 on its side surfaces is. Finally, downstream from the housing section 74, there is also a Housing section 86 connected, which at its from section 74

709844/0097 _ _1? _

2197-98

facing away from the side is closed, but has an outflow connector 88 on one side, in which a suction fan 90 is arranged is. Overall, the result is a channel system that is closed at its two end faces with lateral inputs and Outflow, so that similar channel systems can be connected to the front sides, but each Channel system is flowed through separately from the weather to be cooled.

The heat pipe 76 (Fig. 8) consists of a box-shaped extension 92 of the cooling water line between the input and Outlet stubs 68 and 70. The wide side surface 94 of the extension 92 is directed upstream and extends upstream The capillary structure 96 extends from this side surface 94 up to the inner surface of the upstream end face 98 of the outer container 100, which is at the same time as the capillary structure 96 delimits extension 92. The function corresponds to the usual mode of operation of a heat pipe: the enclosed one Liquid evaporates on the end face 98, condenses on the side face 94 and migrates through the capillary structure 96 back to face 98.

In Fig. 9, a cuboid heat pipe 76 is shown while in the embodiments according to FIGS. 10 or 11, the end face 98 is pointed or arched upstream in order to reduce the flow resistance to reduce and at the same time to increase the evaporation area.

If an increased cooling capacity is required, the described cooling elements can optionally be used instead of a heat pipe also a battery of heat pipes connected in parallel
