Description

Combined cooling device

Technical Field

The utility model relates to the technical field of cooling devices, in particular to a composite cooling device.

Background

In the field of extrusion processing, products produced by extrusion are formed by cooling and hardening materials in a molten state, so that a cooling device is often added on the outlet side of an extruder immediately after extrusion of the materials to accelerate solidification and deformation of the materials. It is common practice to provide a cooling tank capable of storing water, and after the product in a high temperature state contacts the cooling water, heat can be quickly absorbed by the cooling water. The cooling water in the cooling tank is in a flowing state, so heat exchange can be maintained in continuous processing. However, some materials cannot be in direct contact with water, and a conventional cooling tank cannot be used for cooling.

There is therefore a need to develop a new cooling device to solve the above problems.

Disclosure of Invention

The utility model mainly aims to provide a composite cooling device which can help heat exchange of products under the condition of no water wetting.

The utility model realizes the aim through the following technical scheme: the utility model provides a combined type cooling device, includes the open cooling tank in upper portion and hugs closely set up in the cooling chamber of cooling tank lower part, the cooling tank with the cooling chamber separates with the baffle, be equipped with the inlet tube that is used for letting in refrigerant and the outlet pipe that flows out refrigerant on the cooling chamber.

Specifically, the cooling groove and the cooling chamber are of an elongated structure, the inlet pipe is positioned at one end of the cooling chamber in the length direction, and the outlet pipe is positioned at the other end of the cooling chamber in the length direction.

Furthermore, the bottom surface of the cooling chamber is also provided with a plurality of connecting pipes along the length direction of the cooling chamber.

Further, the cross section of the partition plate is in a horizontal straight line shape or a downward concave arc shape.

The technical scheme of the utility model has the beneficial effects that:

the utility model can indirectly cool the material passing through the cooling groove by the refrigerant passing through the cooling chamber, avoids the excessive temperature of the baffle plate, and is suitable for continuous production of the material which cannot be immersed in water for cooling.

Detailed Description

The present utility model will be described in further detail with reference to specific examples.

Examples:

as shown in fig. 1 to 3, a composite cooling device of the present utility model includes a cooling tank 1 having an open upper portion and a cooling chamber 2 disposed closely to a lower portion of the cooling tank 1, wherein the cooling tank 1 and the cooling chamber 2 are partitioned by a partition plate 3, and an inlet pipe 21 for introducing a refrigerant and an outlet pipe 22 for discharging the refrigerant are provided in the cooling chamber 2. A hot material, such as an extruded tube, passes through the interior of the cooling tank 1, the bottom of which contacts the partition 3 and heat is transferred to the partition 3. The refrigerant can be low-temperature cooling water (water cooling) or low-temperature air (air cooling), the refrigerant is introduced into the cooling chamber 2 through the inlet pipe 21, heat exchange is carried out below the partition plate 3, the temperature is increased, and then the refrigerant after the temperature increase is discharged from the cooling chamber 2 through the outlet pipe 22 and takes heat away. According to the utility model, the cooling chamber 2 is communicated with a refrigerant to indirectly cool the material passing through the cooling tank 1, so that the excessive temperature of the partition plate 3 is avoided, and the continuous production of the material which cannot be immersed in water is adapted.

As shown in fig. 1 to 3, the cooling tank 1 and the cooling chamber 2 are each of an elongated structure, the inlet pipe 21 is located at one end of the cooling chamber 2 in the longitudinal direction, and the outlet pipe 22 is located at the other end of the cooling chamber 2 in the longitudinal direction. Under the condition of relatively large heat exchange quantity, the cooling device structure can be made to be relatively slender, the flowing state of the refrigerant from one end to the other end through the cooling chamber 2 is relatively stable, and the problem of refrigerant backmixing is not easy to occur.

As shown in fig. 2 and 3, the bottom surface of the cooling chamber 2 is further provided with a plurality of connection pipes 23 along its length direction. In the case of a relatively long cooling device, a connecting pipe 23 "may be added. The connecting pipe 23 can also be used for introducing refrigerant, which has the function of reducing the temperature of the refrigerant at the entering position, increasing the temperature difference at two sides of the partition board 3 and improving the heat exchange efficiency.

As shown in fig. 3, the cross section of the separator 3 is a horizontal straight line shape. Such a separator 3 has a planar structure. For strip-shaped materials, the bottom surfaces of the materials can be in relatively full contact with the partition plates 3, so that the heat exchange efficiency can be improved.

Example 2

The difference from example 1 is that: the cross section of the partition plate 3 is in a downward concave arc shape. Such a partition 3 will be lower in the middle than on both sides. For tubular materials, the arc-shaped partition plate 3 can enable the materials to automatically slide towards the middle, and the materials cannot deviate to the outer side during conveying.

What has been described above is merely some embodiments of the present utility model. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model.
