Translation of "Fluid cooler" in German

The fluid cooler 14 can be bypassed via a bypass valve 16 .

This condition forces fluid to cooler at lower temperature.

Therefore, an uncontrolled flow of the cooler fluid into the center of the load space 19 can be avoided.

The finished flakes can be rapidly cooled in a fluid-bed cooler or be directly fed to a molding process.

Serving as the cooler is a recuperator through which flows the fluid, which is a part of a cooling regulating circuit and which determines the outlet temperatures of the fluid at the cooler.

Proceeding from the utilization of a thermostat which is equipped in such a manner, it is a further feature of the invention that the cooler and heating arrangement are flowed through in sequence by the fluid, wherein the outlet temperature of the fluid at the cooler is set to a temperature which is below the constant temperature at the outlet of the heating arrangement.

For effecting the cooling of the fluid, the cooler also allows itself to be supplied with a cooling medium which is set to a certain inlet temperature.

The cooling of the pressure fluid in the cooler 5 before entry into the evacuated reservoir 3 has no disadvantageous influence on the effectiveness of the degassing, since the Bunsen dissolving coefficient, for example for air in hydraulic oil between 0° and 100° C., remains practically constant over the relevant temperature range.

In that case, the hot fluid which is discharged by way of the line 53 is replaced by fresh, normally cooler fluid which is drawn in from the tank by way of the distributor line or conduit 16.

For effecting the regulation of the outlet temperature of the fluid at the cooler outlet 10, the cooling regulating circuit includes, in addition to the cooler 3, the P-regulator 7, the temperature sensor 4, and a hydraulically-controlled valve 11, which adjusts the flow quantity of the cooling medium 2.

The through-flow of the cooling medium 2 is thus regulated in dependence upon the actual temperature TKi of the fluid at the cooler outlet 10 (the temperature TKi is measured by the temperature sensor 4), as well as upon the actual temperature THi of the fluid at the outlet 12 of the heating arrangement 9.

The fluid-control device constituting its lower end is provided in order either to block passage of one of the two flow components flowing through the fluid cooler 14 or the bypass conduit 20, or to maintain a particular ratio of these two components.

As a consequence of the formation of the annular gap, coolant fluid can now flow from the fluid cooler 14 into the valve chamber 54, and after mixing with coolant fluid from the bypass conduit 20 it is sent through the supply conduit 36 into the compression space 35 of the compressor 12 .

The consequence is that more coolant fluid flows through the fluid cooler 14, and at the same time the flow component sent through the bypass conduit 20 is diminished.

One of the disadvantages of this design is that the control valve is complicated in structure and subject to malfunction, and furthermore a certain minimal volume flow of coolant fluid passes through the fluid cooler.

As a result, hot leakage fluid 17, hot steam, is mixed with the cooler sealing fluid 15, cooler steam, in the mixing area.

In intermediate positions the summer-/winter-operation actuator 16 merely establishes a minimal position for the width of the upper annular gap 59, and hence for the magnitude of the flow component sent through the fluid cooler 14 .

In an especially preferred embodiment the system-control actuator and the summer-/winter-operation actuator are functionally connected to a common fluid-control device that adjusts the proportion of the coolant-fluid flow that is directed through the fluid cooler, such that the functional connection between the system-control actuator and the fluid-control device is completely or partially interrupted in one direction of action when the summer-/winter-operation actuator is adjusted in the direction towards a summer position.

The coolant fluid reclaimed in the fluid separator 38 in the form of oil flows through a return pipe 40 to a first junction 41, where a cooler conduit 21 branches off to a fluid cooler 14 from which the fluid passes to a second junction 42 .

The sealing fluid used is preferably steam if the leakage fluid is hot steam, in which case the sealing fluid is cooler steam.

Be it as condenser, gas cooler or fluid cooler, and regardless of whether the desired refrigerant is HFC, NH3, CO2, propane or a water/glycol mixture, the V-SHAPE Vario offers everything – plus an extensive range of accessories.

The third fluid channel area 68 is substantially relieved of pressure so that, for example, due to the fact that a fluid flow from the first space area 52 to the second space area 54 can take place via the openings 58, a somewhat higher pressure which can amount to up to 2 bar can be adjusted when the fluid is conducted via a fluid cooler and not directly into a fluid sump.

The fluid bad cooler, an item of equipment which is used in conventional fluidised bed construction, drives the steam circuit.

In the fluid supply line 12 is provided a fluid cooler 14 in which the fluid heated for example in a transmission associated with the clutch is cooled.

Accordingly, a fluid quantity always flows through the fluid cooler 14, which is the sum of the values Q K and Q S .

To maintain a sufficient fluid throughput through the fluid cooler 74 upstream from the control valve 56, as in FIG.

It comprises a first control valve 90 connected to a fluid supply 92, a clutch 94 supplied by the control valve 90, a fluid cooler 96 upstream from the control valve 90 and a reservoir tank 98 for the bypass function, as already described.
