DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made in detail to embodiments of the present disclosure. The embodiments described herein with reference to drawings are explanatory, illustrative, and used to generally understand the present disclosure. The embodiments shall not be construed to limit the present disclosure. The same or similar elements and the elements having same or similar functions are denoted by like reference numerals throughout the descriptions.
The header assembly according to embodiments of the present disclosure will be described below with reference to the drawings. As shown in FIGS. 1-13, the header assembly according to embodiments of the present disclosure may include a header 100, a distribution member, a regulating member 500 and a driving member 600.
The distribution member is disposed within the header 100. The distribution member has at least one distribution opening 401 for distributing refrigerant into the header 100. The regulating member 500 is movably disposed on the distribution member to regulate the distribution opening 401. The driving member 600 is used to drive the regulating member 500 via magnetic force to moves so as to regulate the distribution opening 401.
It shall be appreciated that, the phase “regulate the distribution opening” shall be understood broadly herein in the present disclosure. For example, the phase “regulate the distribution opening” may include adjusting the opening degree of the distribution opening, the position of the distribution opening, the opening direction of the distribution opening or the opening angle of distribution opening. In other words, as far as the movement of the regulating apart results in changing of at least one selected from the group consisting of the amount of refrigerant ejected by the distribution opening, the position where the refrigerant are ejected, the ejecting direction of the refrigerant and the ejecting angle of the refrigerant, it should be appreciated that the distribution opening is regulated.
With the header assembly according to embodiments of the present disclosure, by changing the position of the driving member 600, the position of the regulating member 500 may be changed via magnetic force, and the distribution opening 401 may be regulated. Therefore the distribution of the refrigerant may be adjusted. In this way, the distribution of the refrigerant may be adjusted conveniently as desired, and requirements for different operation conditions may be satisfied, thereby both the applicability and distributing effect of the refrigerant may be improved.
As shown in FIGS. 1-10, in some embodiments, the driving member 600 may be disposed externally of the header 100. Preferably, the driving member 600 may be disposed on an outer wall of the header 100 and the position of the driving member 600 may be adjustable, thus facilitating the assembling and movement of the driving member 600.
It shall be appreciated that, the expression “the position of the driving member 600 may be adjustable” shall be understood broadly herein and includes that the driving member 600 may change its position continuously, and that the driving member 600 may be disposed at different positions. In other words, “the position of the driving member 600 may be adjustable” means that the position of the driving member 600 is changeable.
It shall be appreciated that, the driving member 600 may be disposed at a position other than on the outer wall of the header 100, as far as the distribution opening 401 can be regulated by moving the driving member 600 so as to change the position of the regulating member 500. For example, the driving member 600 may be mounted externally of the header 100 and on a separate support (not shown) which is disposed adjacent to the header 100.
In some embodiments, at least one of the regulating member 500 and the driving member 600 may be configured as a permanent magnet. For example, one of the regulating member 500 and the driving member 600 is a permanent magnet, and the other of the regulating member 500 and the driving member 600 is capable of interacting with the permanent magnet via magnetic force. In an embodiment, the other of the regulating member 500 and the driving member 600 may be configured a steel part. Alternatively, the other of the regulating member 500 and the driving member 600 may be made from other materials. In some embodiments, the regulating member 500 is a permanent magnet, and the driving member 600 is a steel part. Alternatively, the driving member 600 is a permanent magnet, and the regulating member 500 is a steel part. Further alternatively, both the regulating member 500 and the driving member 600 are electromagnets. In an embodiment, the regulating member 500 and the driving member 600 are interacted via magnetic force.
In some embodiments, the distribution member may be configured as a distributing tube 400. The distributing tube 400 may be a circular tube. Alternatively, the cross-section of the distributing tube 400 may have other shapes such as a rectangle and so on.
For the convenience of description, in the following description, the distribution member is embodied as a distributing tube 400 having a circular cross-section, the regulating member 500 is a steel part, and the driving member 600 is a permanent magnet. It shall be appreciated that this is explanary and should not be construed as limitation to the present disclosure.
In some embodiments, the regulating member 500 may be movable in an axis direction of the header 100, and the position of the driving member 600 may be adjustable in the axial direction of the header 100.
As shown in FIGS. 1-3, distributing tube 400 has a plurality of distribution openings 401 spaced apart from each other in an axial direction (left-right direction in FIG. 1, i.e. the axial direction of the header 100) of the distributing tube 400. Specifically, the plurality of distribution openings 401 may be distributed linearly. It is appreciated that, the plurality of distribution openings 401 may be distributed spirally along the axial direction of the distributing tube 400. Alternatively, the plurality of distribution openings 401 may be distributed in any other suitable manners.
Accordingly, one regulating member 500 may be disposed at each distribution opening 401. A sliding groove 402 may be formed in a side wall of the distribution opening 401, and by means of sliding the regulating member 500 along the axial direction of the distributing tube 400, the distribution opening 401 may be regulated. In some embodiments, a plurality of driving members 600 (such as permanent magnet) may be disposed on an outer wall of the header 100. The expression “position of the driving member 600 is adjustable” means the position of the driving member 600 with regard to the header 100 is changeable. For example, the driving member 600 may be slidable with regard to the header 100, or the driving member 600 may be fixed at different positions with regard to the header 100. In some embodiments, the plurality of driving members 600 may be in one-to-one correspondence with the plurality of regulating members 500. When the position of one driving member 600 is changed, the regulating member 500 corresponding to the one driving member 600 may be moved with regard to the distributing tube 400, thus the distribution opening 401 is regulated.
In some embodiments, as shown in FIGS. 1-3, a plurality of protrusions 700 are disposed or formed on an outer wall of the header 100 and in one-to-one correspondence with the plurality of distribution openings 401. The protrusion 700 may include a plurality of grooves 701 formed therein and spaced apart from each other in the axial direction of the header 100. The driving member 600 is adapted to be selectively disposed in any of the plurality of grooves 701. It is appreciated that, the term “selectively dispose” should be understood broadly, i.e. the driving member 600 may be mounted or positioned in any of the plurality of grooves 701. When the driving member 600 is moved from one groove 701 to another groove 701, the position of the driving member 600 is changed, thus driving the regulating member 500 to move and thereby regulating the distribution opening 401.
In some embodiments, the protrusion 700 may be mounted on an outer wall of the header 100 via welding. Alternatively, the protrusion 700 may be fixed to the outer wall of the header 100 via a fixing element such as a clipping element. The driving member 600 may be fixed in the groove 701 via magnetic force. If the protrusion 700 is made from non-metallic material, the driving member 600 may be selectively disposed in the groove 701 in other manners, for example, the driving member 600 may be selectively disposed in the groove 701 via a snap fit.
In some embodiments, one groove 701 may be formed in the protrusion 700 and extended along the axial direction of the header 100. The driving member 600 may be disposed in the groove 701, and slidable in the axial direction of the header 100 so as to change the position thereof.
In some embodiments, as shown in FIGS. 4-6, the distribution opening 401 is formed as an elongated groove extended along the axial direction of the distributing tube 400. The header assembly may include a plurality of regulating members 500 and a plurality of driving members 600 in one-to-one correspondence with the plurality of regulating members 500. The plurality of regulating members 500 are spaced apart from each other in the axial direction of the distributing tube 400. Alternatively, the elongated groove may be extended spirally about the axial of the distributing tube 400, i.e. along a spiral direction. In such cases, the position of the driving member 600 may be adjustable along the spiral direction. In this way, the regulating member 500 may be driven to move along the spiral direction, thus regulating the distribution opening 401.
In some embodiments, a sliding groove 402 may be formed in a side wall of the elongated groove, and the corresponding side of each regulating member 500 is fitted in the sliding groove 402. As shown in FIGS. 1-3, in some embodiments, a plurality of protrusions 700 are disposed on the outer wall of the header 100, a plurality of grooves 701 may be formed in each protrusion 700, and the driving member 600 is adapted to be selectively disposed in any of the plurality of grooves 701. Alternatively, one protrusion 700 is formed on the outer wall of the header 100 and extended along the axial direction of the header 100. A plurality of grooves 701 spaced apart from each other in the axial direction of the header 100, or one groove 701 extended along the axial direction of the header 100 may be formed in the one protrusion 700.
Other structures and operations shown in embodiments shown in FIGS. 4-6 are substantially the same as those in FIGS. 1-3, thus details related thereof are omitted herein.
As shown in FIGS. 7-9, in some embodiments, a plurality of distribution openings 401 are provided, each distribution openings 401 is formed as an elongated groove extended along a circumferential direction of the distributing tube 400. The header assembly includes a plurality of regulating members 500 and a plurality of driving members 600, and the plurality of distribution openings 401 are in one-to-one correspondence with the plurality of regulating members 500, and with the plurality of driving members 600, respectively. The regulating member 500 may be slidable in the circumferential direction of the distributing tube 400. For example, a sliding groove 402 may be formed in a side wall of the elongated groove, and the corresponding side of the regulating member 500 is moveably fitted in in the sliding groove 402. The driving member 600 may be disposed on an outer wall of the header 100, and the position of the driving member 600 may be adjustable in the circumferential direction of the header 100.
In some embodiments, a protrusion 700 may be formed on the outer wall of the header. A groove 701 may be formed in the protrusion 700, and the driving member 600 may be disposed in the groove 701 and the position of the driving member 600 may be adjustable in the circumferential direction of the header 100.
Alternatively, a plurality of grooves 701 may be formed in the protrusion 700, and the driving member 600 is adapted to be selectively disposed in any of the plurality of grooves 701. In other words, the driving member 600 may be positioned or mounted in any of the plurality of grooves 701. Further alternatively, one groove 701 extended along the circumferential direction of the header 100 may be formed in the protrusion 700, and the driving member 600 may be disposed in the one groove 701 and slidable in the circumferential direction of the header 100.
In some embodiments, as shown in FIGS. 8-9, there are a plurality of distribution openings 401 spaced apart in the axial direction of the distributing tube 400. A plurality of protrusions 700 spaced apart along the axial direction of the header 100 may be formed on the outer wall of the header 100, and each of the plurality of protrusions 700 may be extended along the circumferential direction of the header 100.

The groove 701 is configured to receive the driving member 600, and the driving member 600 is adapted to be selectively disposed in any of the plurality of grooves 701. Then the position of the driving member 600 may be changed so as to drive the regulating member 500 to move and to regulate the distribution opening 401. Alternatively, one groove 701 may be formed in each of the plurality of protrusions 700, and the driving member 600 is adapted to be selectively disposed in the one groove 701 and is slidable in the one groove 701.
It is appreciated that, the protrusion 700 corresponding to each distribution opening 401 may be extended along the circumferential direction of the header 100 and be integrally formed as a single piece. Alternatively, the protrusion 700 may include a plurality of sub-protrusions spaced apart from each other in the circumferential direction of the header 100.
In some embodiments, the distribution opening 401 configured as the elongated groove may extend spirally about the axis of the distributing tube 400 (i.e. along a spiral direction), and the position of the regulating member 500 is adjustable in the spiral direction. In this way, the regulating member 500 may be driven to move in the spiral direction, thus regulating the distribution opening 401.
By means of disposing the driving member 600 on the outer wall of the header 100, the regulating member 500 positioned in the header 100 may be driven to move the regulating member 500, thus regulating the distribution opening 401.
