Description
Technical Field
The utility model relates to an air conditioner component, especially a dry evaporator's component, specific pipe case structure for refrigeration dry evaporator that says so.
Background
Among the four major components of the refrigeration system, the evaporator is a heat exchanger accompanied by an evaporative (boiling) phase change, and the coolant is cooled by evaporating the coolant liquid into vapor by the evaporator absorbing the heat of the coolant. In the dry evaporator, a secondary refrigerant flows outside a shell-side heat exchange tube, and the refrigerant flows through a tube box and flows inside the heat exchange tube. The tube box is used for uniformly distributing tube side fluid in each heat exchange tube and collecting the fluid in the tubes and then discharging the fluid out of the heat exchanger. In such a multi-pass heat exchanger, the header also serves to change the direction of fluid flow.
At present, a partition plate is welded in a tube box to divide refrigerant into a plurality of flow paths. However, heat treatment is required after welding, which complicates the process and increases the manufacturing cost. Moreover, when the liquid homogenizing plate is arranged subsequently, the positioning is not easy, and the production efficiency is influenced.
Therefore, improvements are urgently needed in order to better meet the market demands.
SUMMERY OF THE UTILITY MODEL
The utility model aims at prior art's not enough, provide a refrigeration is pipe case structure for dry evaporator, can avoid the thermal treatment process after the welding, simplify the production procedure, moreover, still can make things convenient for the installation of follow-up equal liquid board, improve production efficiency.
The technical scheme of the utility model is that:
a tube box structure for a refrigeration dry type evaporator comprises a cylindrical body, wherein a separation rib is arranged in the cylindrical body; the partition rib is in a straight plate shape, the width of the partition rib is equivalent to the length of the body, and two ends of the partition rib are respectively connected with the inner wall of the body to divide the interior of the body into an upper cavity and a lower cavity which are mutually independent; the spacer ribs and the body are of an integrated structure; the inner wall in cavity is the step form under the body, can be with equal liquid board joint on this step.
Furthermore, the length of the separating rib is equivalent to the inner diameter of the body and is arranged at the diameter of the body, so that the upper cavity and the lower cavity are both semicircular.
Further, two ends of the body are respectively sealed by a flat cover and a tube plate of the dry evaporator; the step faces the flat cover.
Further, the steps are two or more.
The utility model has the advantages that:

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2.
A tube box structure for a refrigeration dry type evaporator comprises a body 1.
The body 1 is cylindrical, and a spacer 2 is arranged in the body. The spacer 2 is in a shape of a straight plate, the width of the spacer corresponds to the length of the body 1, and the length of the spacer corresponds to the inner diameter of the body 1. Should separate muscle 2 set up in the diameter department of body 1, its both ends respectively with body 1 inner wall links to each other, will body 1 internal partitioning becomes mutually independent, and is semicircular epicoele and cavity of resorption. Meanwhile, the spacer ribs 2 and the body 1 can be manufactured into an integrated structure through forging and other processes, so that the strength of the structure can be improved, the conventional machining procedure of heat treatment after welding can be omitted, the manufacturing process is simplified, and the production efficiency is improved.
The inner wall of the lower cavity of the body 1 is step-shaped, so that the rigidity of the body 1 can be ensured, and the liquid homogenizing plate 4 can be clamped on the step 3 to be accurately positioned when the liquid homogenizing plate is conveniently installed subsequently. Preferably, the step 3 is two-stage or more than two-stage so as to be capable of installing more than one liquid equalizing plate and meet the production requirement.
As shown in fig. 3, a refrigerating dry evaporator, which has the basic structure substantially the same as that of the existing dry evaporator, comprises a cylinder 10, a flat cover 7, a tube plate 8, a heat exchange tube 9, a liquid inlet tube 5, an air outlet tube 6, etc. The body 1 is arranged between the flat cover 7 and the tube plate 8, and the step faces the flat cover 7, so that the liquid equalizing plate can be conveniently installed.
The utility model discloses a to separate muscle and body system integral type, not only can guarantee the requirement of processing rigidity, can avoid the heat treatment process after the welding in the past again, reduced the processingquantity. Meanwhile, the inner wall of the lower cavity of the body is arranged to be step-shaped, so that the subsequent liquid homogenizing plate can be conveniently installed, and the production efficiency is improved.
The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
