In addition, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present application. It will be understood by those skilled in the art that the present application may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present application.
A sealing device S according to the present application will be described with reference to fig. 1 to 13, taking as an example a heat exchanger core for an indirect evaporative cooling unit.
Referring to fig. 1, an indirect evaporative cooling unit includes one or more (typically a plurality of) heat exchanger cores C. Each heat exchange core C is, for example, a substantially rectangular parallelepiped structure. A plurality of heat exchange cores C are fixed by a frame F to be arranged in an array. The heat exchange core C is internally distributed with a plurality of channels which are intersected with each other, and two flows with different temperatures can flow along the respective channels after being introduced into the heat exchange core C, and the two flows cannot be directly contacted in the heat exchange core C. The two air flows are respectively heat exchanged by exchanging heat with the heat exchange core C.
In the operating condition, the heat exchange core C is clamped (e.g., in the second direction D2 shown in fig. 1) to the frame F by the sealing device S.
In maintenance (including service and replacement) conditions, the sealing device S releases the core C which can be removed, e.g., pushed or pulled, from the frame F in a first direction D1, as shown in fig. 1.
(first embodiment)
Referring to fig. 2 to 8, a sealing device S according to a first embodiment of the present application will be described.
In this embodiment, the sealing device S includes a body 10, a fixing member 20, a hinge 30, a first pin 40, a spring 50, and a second pin 60.
The fixing member 20 is used to be fixedly connected with the frame F. Hereinafter, for convenience of description, the fixing member 20 and the frame F are not particularly distinguished from each other in some cases.
The hinge 30 rotatably connects the main body 10 to the fixing member 20 (i.e., the frame F). Referring to fig. 2, the body 10 can rotate (or swing) relative to the fixing member 20 in a direction indicated by an arrow ω.
The body 10 is elongated and extends in a first direction D1, and the heat exchange core C is disposed adjacent to the body 10 in a second direction D2 perpendicular to the first direction D1. During the oscillation of the main body 10 along the arrow ω, the upper end of the main body 10 in fig. 2 is displaced in the second direction D2, so that the main body 10 can clamp or unclamp the heat exchange core C in the second direction D2.
For example, it is defined that when the body 10 is swung to the first position, the heat exchange core C is in (clamped) state; it is defined that the heat exchange core C is in the (released) state when the main body 10 is swung to the second position.
With the heat exchange core C in the clamped state, the first pin 40 and the second pin 60 are in the locked state; with the core C in the unclamped state, the first and second pins 40 and 60 are in the unlocked state.
Referring next to fig. 3 to 8, the locking manner of the first and second pins 40 and 60 to the body 10 will be described in detail.
Referring to fig. 3, the body 10 includes a plurality of mounting portions 100 having through holes (only one mounting portion 100 is shown since fig. 3 shows only a portion of the sealing device S in the first direction D1). The through holes (also referred to as body first through holes) of the plurality of mounting portions 100 are aligned in the first direction D1, and the first pin 40 is mounted to the body 10 so as to be capable of reciprocating in the first direction D1 through the through holes of the mounting portions 100. The mount 100 provides a guide for movement of the first pin 40 in the first direction D1.
It should be understood that the present application is not limited to the specific arrangement of the mounting portion 100, and it can be said that the main body 10 is sleeved on the outer periphery of the first pin 40 through the mounting portion 100.
In the first direction D1, the length of the first pin 40 is greater than the length of the body 10. Both end portions of the first pin 40 are respectively formed as a first pin head portion 41 and a first pin tail portion 42, the first pin head portion 41 serving as an operating end, and the first pin tail portion 42 serving as a locking end.
The fixing member 20 includes a first fixing member 21 and a second fixing member 22. In the first direction D1, the first fixing member 21 is disposed near the first pin tail portion 42, and the second fixing member 22 is disposed near the first pin head portion 41 (see fig. 4 and 5 at the same time).
Referring to fig. 3 and 6 together, the first fixing piece 21 is formed with a first pin hole 21a, and the first pin hole 21a is aligned with the through hole of the mounting portion 100 in the first direction D1 when the body 10 is swung to the first position. In this state, the first pin tail portion 42 can pass through the first pin hole 21a, thereby locking the main body 10 in the first position. The position of the first pin 40 at this time is also referred to as the first working position of the first pin 40.
To ensure a secure locking of the first pin 40 and to facilitate the handling of the first pin 40, the first pin 40 is peripherally sleeved with a spring 50. Both ends of the spring 50 are connected to the first pin 40 and the body 10, respectively. When the first pin 40 is in the locked state, the spring 50 applies a pushing force (preload) to the first pin 40 toward the first fixing piece 21 so that the first pin 40 is maintained in a state of passing through the first pin hole 21a.
In the case that the first pin 40 needs to be unlocked, the first pin head 41 can be pulled in the direction indicated by the hollow arrow in fig. 3, and the first pin tail 42 can be disengaged from the first pin hole 21a against the pre-tightening force of the spring. The position of the first pin 40 is also called the second working position of the first pin 40.
It will be appreciated that the spring 50 may act to automatically rebound the first pin tail 42 during switching of the first pin 40 from the second operating position to the first operating position.
Referring to fig. 5 and 7 together, the second pin 60 is mounted to an end of the body 10 near the first pin head 41. The first pin 40 and the second pin 60 respectively play a locking role for the body 10 at both end portions of the body 10.
The second pin 60 extends perpendicularly with respect to the first direction D1, and the second pin 60 is connected to the body 10 through a body second through hole formed in the body 10. The second pin 60 includes a second pin head 61 as an operating end and a second pin tail 62 as a locking end. The second pin tail portion 62 can pass through the second pin hole 22a formed in the second fixed member 22.
Alternatively, the second pin 60 is a spring pin, and the tail 62 of the second pin naturally extends through the second pin hole 22a, so that the second pin 60 is locked and the main body 10 abuts against the core C.
In the event that it is desired to unlock the second pin 60, the second pin tail 62 may be disengaged from the second pin hole 22a by pulling on the second pin head 61.
Alternatively, referring to fig. 8, the main body 10 has a semi-closed sleeve shape including a bottom plate 111, an inner side plate 112, an outer side plate 113, and an upper plate 114. The bottom plate 111 has a strip-like plate shape. In the second direction D2, the inner plate 112 is disposed at an end of the base plate 111 close to the core C (not shown in fig. 8), and the outer plate 113 is disposed at an end of the base plate 111 remote from the core C. The upper plate 114 is connected to the inner side plate 112, and the upper plate 114 is disposed opposite to the bottom plate 111. Thus, a semi-closed space is enclosed by the bottom plate 111, the inner plate 112, the outer plate 113, and the upper plate 114. The mounting portion 100 and the first pin 40 are disposed within the semi-enclosed space.
Optionally, the body 10 further comprises a sealing strip 10s. The sealing strip 10s is mounted on the face of the inner side plate 112 facing the heat exchange core C in the second direction D2. The sealing strips 10s serve to reinforce the sealing action between the body 10 and the heat exchange core C. That is, the body 10 can press the sealing strip 10s in the second direction D2 to bring the sealing strip 10s into close contact with the heat exchange core C. The sealing tape 10s is made of a material having flexibility, and for example, the material of the sealing tape 10s includes rubber or silicone or fiber.
In the first direction D1, the first pin head 41 and the second pin head 61 are both located at the same end of the body 10, which makes it very easy to operate the locking and unlocking of the body 10. Especially, with the body 10 having a large size in the first direction D1, it is not necessary to separately operate at both distant ends, but only at one end, so that the locked state of both ends of the body 10 can be controlled.
It will be appreciated that since both the first pin 40 and the second pin 60 act as a lock of the position of the body 10, in possible variant embodiments it is also possible to use the second pin 60 at both ends of the body 10 or a structure similar to the first pin 40.
(second embodiment)
Next, referring to fig. 9 to 13, a sealing device S according to a second embodiment of the present application will be described. The second embodiment is a modification of the first embodiment, the same reference numerals are used in the present embodiment for the same or similar features as those of the first embodiment, and detailed description of these features is omitted.
In the present embodiment, the clamping and releasing of the heat exchange core C by the main body 10 is not achieved by the rotation of the main body 10 relative to the fixing member 20 (or the frame F), but by the reciprocating movement of the main body 10 relative to the fixing member 20 in the second direction D2.
In this embodiment, the sealing device S includes a main body 10, a fixing member 20, a rotation shaft 300, a guide block 400, a positioning block 500, and a connection member 600.
The main body 10 includes an inner side plate 112 and a plurality of mounting portions 100. The mounting portion 100 is disposed on a side of the inner plate 112 facing away from the core C. The shaft 300 passes through the through holes of the plurality of mounting portions 100, or the mounting portions 100 are sleeved on the shaft 300. The rotary shaft 300 can rotate about its axis with respect to the main body 10.
The guide block 400 is cam-shaped, and the guide block 400 is connected to the rotary shaft 300 so as not to be rotatable relative thereto.
Referring to fig. 9 and 13 together, the fixing member 20 includes a fixing guide 200. The fixing guide 200 is in the form of a bracket, and includes a stopper wall 201 and a guide wall 202. The stop wall 201 is used to provide an abutment base for the guide block 400, and the guide wall 202 is used to provide support and guiding of the reciprocating motion for the rotating shaft 300.
Alternatively, both axial ends of the rotation shaft 300 are provided with the fixing guide 200.
The guide wall 202 is formed with a guide groove 200a extending in the second direction D2. Alternatively, the guide groove 200a is formed in the shape of a long waist hole. The rotation shaft 300 passes through the guide groove 200a, and the guide groove 200a restricts the movement of the rotation shaft 300 so that (without considering the translation of the rotation shaft 300 in the first direction D1) the rotation shaft 300 can only make rotation around its axis and translation along the guide groove 200a (i.e., in the second direction D2).
Alternatively, in order to limit the translation of the rotating shaft 300 along its axis (along the first direction D1), for example, the mounting portion 100 and the guide wall 202 may be respectively disposed at two axial sides of the guide block 400 and in a position very close to the guide block 400, so that the mounting portion 100 and the guide wall 202 limit the rotating shaft connected to the guide block 400 in the first direction D1.
Optionally, the guide groove 200a has an opening facing the body 10, so as to facilitate the insertion of the rotation shaft 300 into the guide groove 200a in the second direction D2.
In the second direction D2, the stop wall 201 is disposed on a side of the rotation shaft 300 facing away from the main body 10. The guide block 400 abuts the stopper wall 201. Since the guide block 400 has a cam shape, the distance from the center of the rotation shaft 300 to the stopper wall 201 in the second direction D2 will vary during the rotation of the guide block 400 with the rotation shaft 300; correspondingly, the distance between the main body 10 and the heat exchange core C in the second direction D2 can be changed, so as to clamp and release the heat exchange core C by the main body 10.
Alternatively, referring to fig. 12, the abutment surface 401 of the guide block 400 for contacting the stopper wall 201 is involute in a cross section perpendicular to the first direction D1. This enables the rotation of the guide block 400 with respect to the stopper wall 201 to be smoothly performed.
Defining the heat exchange core C in a clamped state when the main body 10 is moved to the first position in the second direction D2; when the main body 10 is moved to the second position, the heat exchange core C is in the unclamped state.
Alternatively, when the main body 10 is moved to the first position, the positioning block 500 is fixedly connected to the guide 200, and the rotation shaft 300 cannot move in the second direction D2 at this time. Thereby fixing the rotation shaft 300, the positioning block 500, the guide block 400 and the main body 10 at the first position and maintaining the clamping of the heat exchange core C. Specifically, for example, the positioning block 500 is formed with a through hole 500a, the guide wall 202 is formed with a positioning hole 200b (e.g., a threaded hole), and is connected to the positioning hole 200b through the through hole 500a using a connection member 600 (e.g., a screw).
Alternatively, both end portions of the rotation shaft 300 in the first direction D1 are formed with a hexagonal head-shaped rotation shaft end portion 301, and the rotation shaft end portion 301 may be engaged with, for example, a wrench so that the rotation shaft 3 may be wrenched (rotated) using the wrench.
In case that the clamping state of the heat exchange core C needs to be adjusted, the coupling of the positioning block 500 with the guide 200 is released. Then, the rotating shaft 300 is rotated, and the rotating shaft 300 moves in the second direction D2 under the guidance of the guide groove 200a as the contact point of the guide block 400 and the stopper wall 201 changes, so that the clamping state of the main body 10 to the heat exchanging core C changes.
It should be understood that at least one of the guide block 400 and the positioning block 500 may be integrally provided with the rotation shaft 300.
It should be understood that the sealing means of the present application may be installed on both sides of the heat exchange core C in the second direction D2; it is also possible to mount only one side of the heat exchanger core C and use the fixed frame F as a counterpart on the other side.
It should be appreciated that the present application also provides an indirect evaporative cooling unit including a seal S.
It should be understood that the sealing device according to the present invention may be used to seal other structures (also referred to as seals) requiring pull maintenance, such as, but not limited to: a fan module and a filter screen module in the indirect evaporative cooling unit.
The present application has at least one of the following advantages:
(i) The sealing device can conveniently move relative to the sealed piece, and meets the requirement that the sealed piece needs to be maintained in a drawing mode while the sealed piece is sealed.
(ii) The inboard of main part 10 is equipped with sealing strip 10s, can realize well sealedly through main part 10 extrusion sealing strip 10s, has avoided setting up fasteners such as screw on being sealed by, especially to the heat transfer core, has effectively avoided the high-order operation of heat transfer core to beat the problem of the little difficult operation in space that the screw faced, has also avoidd the fastener and has relapseed the dismouting and destroy the shortcoming of original leakproofness simultaneously, has further promoted sealed effect.
