Referring to fig. 1 to 3, the blower assembly 10 includes a mounting substrate 100 and a blower unit 200. The mounting substrate 100 may be provided with a through hole or a through groove so that the blower unit 200 is received in the through hole or the through groove. The fan unit 200 has a first mounting state and a second mounting state with respect to the mounting substrate 100. The fan unit 200 in the first mounting state is mounted above the mounting substrate 100 and straddles the through hole or the through groove. The blower unit 200 in the second installation state is inserted into the through hole or the through groove. So, when fan unit 200 was in first installation status, fan unit 200 can be in the running state, and when fan unit 200 was in the second installation status, fan unit 200 can be accomodate in the cooling unit, had reduced the overall height of cooling unit, was favorable to the transportation of cooling unit.

The mounting substrate 100 may be a closed plate-like structure. The mounting substrate 100 has a first surface 101 and a second surface 102. The first surface 101 and the second surface 102 are located on opposite sides of the mounting substrate 100, and the mounting substrate 100 is provided with a mounting through-hole 103, and the mounting through-hole 103 penetrates through the first surface 101 and the second surface 102. In this embodiment, the first surface 101 may be a top surface of the mounting substrate 100, the second surface 102 is a bottom surface of the mounting substrate 100, and the first surface 101 and the second surface 102 are disposed in parallel, so as to facilitate reducing the thickness of the mounting substrate 100 and facilitating manufacturing. In addition, the mounting substrate 100 has a function of accommodating the fan unit 200, and can limit the fan unit 200 in the second mounting state to prevent the fan 220 from moving in the horizontal direction.

Further, as shown in fig. 4, the shape of the installation through hole 103 may be a rectangular through hole, so as to facilitate the fan unit 200 to penetrate through the installation through hole 103, facilitate the fan unit 200 to be accommodated in the cooling unit, and further facilitate the transportation of the cooling unit. The mounting through-hole 103 includes a long side 105a and a short side 105b. The length of the long side 105a (i.e., the length of the mounting through-hole 103) is greater than the length of the short side 105b (i.e., the width of the mounting through-hole 103). In this embodiment, there are two long sides 105a, two long sides 105a are disposed oppositely, there are two short sides 105b, and two short sides 105b are disposed oppositely and connected between the two long sides 105a to enclose the mounting through hole 103.

Fan unit 200 includes a fan cage 210, a fan 220, and a hanger 230. The blower 220 is installed in the blower cage 210, and the hanger 230 is attached to the circumferential wall of the blower cage 210. When the fan unit 200 is in the first installation state, the fan unit 200 is installed on the first surface 101 and straddles the installation through hole 103, for example, the fan unit 200 abuts against the first surface 101 and is installed above the installation through hole 103. When the fan unit 200 is in the second installation state, the hanging lug 230 abuts against the first surface 101, so that the fan cage 210 is stably inserted into the installation through hole 103.

The approximate outline of the blower cage 210 may be a square or rectangular parallelepiped, so that the mounting substrate 100 receives the blower unit 200. The fan cage 210 has an inlet and an outlet 201, for example, the inlet may be disposed at the bottom of the fan cage 210, and the outlet 201 may be disposed at the peripheral side of the fan cage 210.

The cross section 106 of the blower cage 210 is rectangular in shape (e.g., cross section), the length L1 of the cross section 106 is greater than the width of the mounting through hole 103 (i.e., the length of the short side 105 b), the width L2 of the cross section 106 of the blower cage 210 is less than the width of the mounting through hole 103, and the length L1 of the cross section 106 of the blower cage 210 is less than the length of the mounting through hole 103 (i.e., the length of the long side 105 a). As shown in fig. 5, the length L1 of the cross section 106 of the fan cage 210 is greater than the width of the mounting through hole 103, so that the bottom of the fan cage 210 can abut against the first surface 101, thereby allowing the fan unit 200 to be in the first mounting state. As shown in fig. 6, the length L1 of the cross section 106 of the fan cage 210 is smaller than the length of the mounting through hole 103 (i.e., the length of the long side 105 a), and the width L2 of the cross section 106 of the fan cage 210 is smaller than the width of the mounting through hole 103 (i.e., the length of the short side 105 b), so that after the fan cage 210 rotates, the width L2 side of the cross section 106 of the fan cage 210 is opposite to the short side 105b, the length L1 side of the cross section 106 of the fan cage 210 is opposite to the long side 105a, and the fan cage 210 can pass through the mounting through hole 103, so that the fan unit 200 can be in the second mounting state.

In this embodiment, the blower cage 210 has a first end 211 and a second end 212, and the first end 211 and the second end 212 are disposed opposite to each other in the axial direction of the blower cage 210. The first end 211 of the blower cage 210 in the first installed state is mounted to the first surface 101, e.g., the first end 211 may abut the first surface 101. The first end 211 of the blower cage 210 in the first installed condition is on the same side as the first surface 101. The first end 211 of the blower cage 210 in the second installed configuration is on the same side as the second surface 102 and the second end 212 is on the same side as the second surface 102. The air inlet is disposed on an end surface of the first end 211 facing away from the second end 212, and the air outlet 201 is disposed on a peripheral side between the first end 211 and the second end 212, so that the structure of the blower cage 210 is more compact.

The fan 220 may be configured for use as a suction fan 220 in a chiller assembly. The fan 220 may be any one of a centrifugal fan 220, an axial fan 220, or a cross-flow fan 220, and is not limited thereto.

The ear loop 230 includes a plurality of ear loops 231, and the plurality of ear loops 231 are coupled to the second end 212. For example, a plurality of ear pieces 231 may be screwed with the second end 212. In order to increase the air outlet effect, a plurality of air outlets 201 may be disposed on the peripheral side of the blower cage 210, and an ear hanging piece 231 is disposed between two adjacent air outlets 201. When the fan unit 200 is in the second mounting state, the ear piece 231 abuts against the first surface 101. In order to further accommodate the fan unit 200 in the mounting through hole 103, the hanging lug 231 is disposed near the end surface of the second end 212, so that the end surface of the second end 212 of the fan unit 200 in the second mounting state is disposed near the first surface 101, and most of the fan unit 200 can pass through the mounting through hole 103 and be located on the second surface 102 side of the mounting substrate 100, which is more beneficial to reducing the overall height of the cooling unit (i.e., the height of the fan unit protruding from the first surface 101 of the mounting substrate 100), and further beneficial to transportation of the cooling unit.

The ear piece 231 includes a first connection portion 231a and a second connection portion 231b, the first connection portion 231a is connected to the blower cage 210, for example, the first connection portion 231a may be screwed or welded with the blower cage 210. The second connection portion 231b is connected to the first connection portion 231a, and the second connection portion 231b may be screwed or welded to the first connection portion 231 a. The second connection portion 231b has an abutment surface 231c, and the abutment surface 231c of the second connection portion 231b of the fan unit 200 in the second mounting state abuts the first surface 101, so that the mounting substrate 100 can support the fan unit 200 in the second mounting state by the ear piece 231.

In some embodiments, the blower unit 200 may further include a hanger 230 fixture, for example, the hanger 230 fixture may be a screw, and the second connection portion 231b may be detachably connected to the first surface 101 through the hanger 230 fixture. For example, the second connection portion 231b of the fan unit 200 in the second installation state is inserted into the installation through hole 103 and can be stably fixed on the installation substrate 100 by the fixing member of the hanging lug 230, so that the fan unit 200 in the second installation state is prevented from vibrating, and the fan unit 200 is protected. When the fan unit 200 is switched from the second installation state to the first installation state, the hanging lug 230 may be detached, so that the fan unit 200 is switched to the first installation state.

When the fan unit 200 is switched from the first installation state to the second installation state, since the length L1 of the cross section 106 of the fan cage 210 is smaller than the length of the long side 105a of the installation through hole 103 and the width L2 of the cross section 106 of the fan cage 210 is smaller than the length of the short side 105b of the installation through hole 103, the fan cage 210 is lifted first, then rotated by a certain angle with the axis of the fan cage 210 as the rotation axis, and the fan cage 210 is made to pass through the installation through hole 103, and finally the abutting surface 231c of the ear piece 231 is made to abut against the first surface 101, so that the fan unit 200 is made to be in the second installation state. When the fan unit 200 is switched from the second installation state to the first installation state, since the length L1 of the cross section 106 of the fan cage 210 is greater than the length of the short side 105b of the installation through hole 103, the fan cage 210 is lifted first, and then is rotated by a certain angle with the axis of the fan cage 210 as the rotation axis, so that the bottom of the fan cage 210 can abut against the first surface 101 and straddle the installation through hole 103, and thus the fan unit 200 is in the first installation state.

Since the fan unit 200 in the first installation state is operable, when the fan unit 200 is operated, the fan unit 200 may vibrate, so that the fan unit 200 may move on the first surface 101, and as the rotation speed of the fan unit 200 increases, the fan unit 200 may easily collide with other components.

In view of this, in some embodiments, fan unit 200 further includes fasteners 400, fasteners 400 being removably attached to fan cage 210 and mounting base plate 100. For example, when the fan unit 200 is in the first installation state, the fastener 400 may be screwed or snapped to the fan cage 210 and the installation substrate 100, so as to fix the fan unit 200, prevent the fan unit 200 from moving on the first surface 101, and prevent the fan unit 200 from colliding with other components. When the fan unit 200 is in the second installation state, the fastener 400 can be detached.

Since the fan unit 200 in the second installation state may be inserted into the installation through hole 103, there may be a gap between the fan cage 210 and the installation substrate 100 when the fan unit 200 is in the first installation state. The fan unit 200 may leak air during operation.

In view of this, in some embodiments, the fan assembly 10 includes a cover plate 300, the cover plate 300 being removably mounted to the first surface 101, sealing the gap between the mounting substrate 100 and the fan cage 210 in the first mounted state. The damper may be screwed and snapped to the blower cage 210 and the first surface 101.

Further, the sealing plate 300 includes a first sealing portion 310 and a second sealing portion 320, and the first sealing portion 310 and the second sealing portion 320 may be plate-shaped structures. The second sealing portion 320 is connected to the first sealing portion 310, for example, the first sealing portion 310 may be welded with the second sealing portion 320. The first sealing portion 310 is attached to the blower cage 210, and the second sealing portion 320 is detachably attached to the mounting substrate 100, for example, the second sealing portion 320 may be screwed with the mounting substrate 100. When the fan unit 200 is in the first installation state, the first sealing portion 310 is connected to the fan cage 210, and the second sealing portion 320 is connected to the installation substrate 100 in a sealing manner, so that the sealing plate 300 can seal the gap between the fan cage 210 and the installation substrate 100, and prevent the fan assembly 10 from leaking air. When the fan unit 200 is in the second mounting state, the sealing plate 300 needs to be detached to prevent the sealing plate 300 from interfering with the mounting substrate 100.

In some embodiments, the cover plate 300 is a foldable cover plate 300, for example, the first sealing portion 310 and the second sealing portion 320 are hinged, and when the fan unit 200 needs to be switched to the second installation state, the second sealing portion 320 can be rotated and the second sealing portion 320 can be folded to the first sealing portion 310.

Further, the blower cage 210 further includes a closing plate 300 fixing member, and the closing plate 300 fixing member may be a screw or a latch. When the fan unit 200 needs to be switched to the second installation state, the fixing member of the sealing plate 300 fixes the folded sealing plate 300 to the fan cage 210, that is, the fixing member of the sealing plate 300 fixes and folds the second sealing portion 320 to the first sealing portion 310.

The invention further provides a cooling unit which can be applied to the machine room of the data center and used for cooling the cabinet equipment of the machine room. The cooling unit includes a cabinet and the fan assembly 10 according to the above embodiment, and the fan assembly 10 is mounted on the cabinet through the mounting substrate 100.
