Description

(5) HEAT TRANSFER DEVICE

one

The invention relates to heat engineering and can be implemented in systems for the use of secondary energy resources in various industries.

A heat transfer device is known, comprising a housing with inlet and outlet nozzles and a shaft rotating on a shaft and equipped with finned heat pipes.

A disadvantage of the known device is the design complexity and low intensity of heat exchange.

The purpose of the invention is to simplify the design and intensify heat exchange.

The goal is achieved by the fact that the shaft is hollow in the form of a distribution manifold of the type. the pipe is in the pipe, and the axes of the heat pipes are arranged 1 4 along the radii of the drum with the formation of rows, between which the annular partitions are placed for the multi-pass movement of the coolant. Moreover, the housing with the drum is connected by means of a labyrinth seal.

The drawing on the same image shows the proposed device.

The device includes a housing.1 with nozzles input 2 and output 3 of the coolant and rotations on the shaft k

10 a drum 5 provided with finned heat pipes 6, the shaft being hollow in the form of a distribution manifold of a pipe-like type in a pipe, and the axes of the heat pipes 6 are arranged

15 along the radii of the drum 5 with the formation of rows, which are placed annular partitions 7 for multi-pass movement of the coolant, the housing 1 with the drum 5 are connected by 20 means of a labyrinth seal 8, the distribution manifold has nozzles 9 and 10, which are also connected via a labyrinth.

seals 8. Heat pipes have fins P.

The device works as follows.

Hot coolant, such as flue gas, flows through the spout 2 into the annular cavity of the housing 1 formed by its end wall and partition 7, and then passes through the remaining annular cavities and exits through the nozzle 3. Due to the heat of this flow, evaporation occurs the working substance contained in the heat pipes 6. A cold stream, for example air, is supplied through the nozzle 10 of the cavity of the drum 5, and the passage is successively annular channels formed by partitions 7. washes the condensation part ovyh pipes 6. As a result, couples the formed in the evaporator portion of heat pipe 6, condensed and transfer heat to the cold stream. The condensate under the action of centrifugal forces returns to the evaporation part of the heat pipes 6. Next, the heated coolant is discharged from the device through the pipe 9.

Thus, the proposed heat transfer device is easy

in constructive design and manufacturing technology, and allows intensive transfer of heat from one heat carrier to another.
