Freeze drying's heat exchange device

Technical Field

The utility model belongs to the technical field of the relevant technique of freeze-drying and specifically relates to indicate a freeze-drying's heat exchange device.

Background

Compressed air is an important power energy source in industrial manufacturing, the compressed air contains a large amount of moisture, the moisture in the compressed air can be dried by a freeze dryer, namely, the compressed air enters an evaporator to exchange heat with a refrigerant in a thin tube of the evaporator, the moisture in the compressed air is condensed into liquid water after the temperature is reduced, and the moisture is filtered and discharged out of the machine through a water-vapor separator, so that the drying purpose is achieved. The refrigerant in the narrow tube of the evaporator is generally cooled by the condenser and then recycled.

The evaporator and the condenser are two important heat exchange devices in the freeze dryer, and the heat exchange efficiency of the evaporator and the condenser determines the energy efficiency of the refrigeration system. The traditional evaporator or condenser consists of a circuitous copper pipe and radiating fins welded on the copper pipe, and has low integration level and larger volume.

A first channel and a second channel are arranged in the machine body, the first channel can be a refrigerant (or other refrigeration media), and gas passes through the second channel, so that the purpose of heat exchange is achieved; a plurality of medium pipes; the second channel is wound on the medium pipe, and the medium pipe is connected in series through the second channel, so that the contact area is increased, and the heat exchange efficiency is improved. The design achieves the purpose of high heat exchange efficiency.

Preferably, the inner side of the cover is provided with an internal thread, and the machine body is provided with an external thread corresponding to the internal thread, so that the equipment is convenient to open, and the daily inspection and maintenance are convenient.

Preferably, a heat insulation layer is arranged in the machine body and filled around the medium pipe, and the heat insulation layer is added to have a heat insulation function on the refrigerant in the medium pipe, so that the temperature of the refrigerant is kept stable, and the energy loss is avoided.

Preferably, the medium pipe is provided with sawteeth, the channel two-way pipe is wound on the medium pipe through the sawteeth, the sawteeth increase the contact area of the medium pipe and the channel two-way pipe, the sawteeth wound on the medium pipe are crossed by the channel two-way pipe, the contact area of the channel two-way pipe and the medium pipe can be increased, and the heat exchange rate can be provided.

Preferably, the second channel is in a round pipe shape, the volume of the second channel is reduced, the number of winding turns can be increased, the contact area is increased, and the heat exchange rate is increased.

The utility model has the advantages that: the heat exchange efficiency is high; the equipment volume is small; the disassembly and the maintenance are convenient; the structure is simple.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic view of the structure within the fuselage.

In the figure: 1. the heat insulation pipe comprises a first channel, a second channel, an inlet, a second channel, an outlet, a cover, a body, an inner thread, an outer thread, an insulating layer, sawteeth, a medium pipe and a heat insulation layer, wherein the first channel is 2, the inlet is 3, the second channel is 4, the outlet is 5, the cover is 6, the body is 7, the inner thread is 8, the outer thread is.

Detailed Description

The invention is further described with reference to the accompanying drawings and the detailed description.

In the embodiment shown in fig. 1 and 2, the heat exchange device for freeze drying comprises a box body, wherein the box body is divided into a cover 5 and a machine body 6, a first channel 1 and a second channel 3 are arranged in the machine body 6, the first channel 1 is provided with an inlet 2, an outlet 4 and a plurality of medium pipes 11, the inlet 2 and the outlet 4 are both communicated with the medium pipes 11, the second channel 3 is wound on the medium pipes 11, and the medium pipes 11 are connected in series through the second channel 3. The inner side of the cover 5 is provided with an internal thread 7, and the body 6 is provided with an external thread 8 corresponding to the internal thread 7.
