Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a plate heat exchanger fixing structure and air conditioning equipment. Background Art

[0002] A plate heat exchanger is a highly efficient heat exchanger composed of a series of stacked, corrugated metal sheets. Thin rectangular channels are formed between the plates, through which heat is exchanged. Plate heat exchangers are ideal for liquid-to-liquid and liquid-to-vapor heat exchange. They feature high heat transfer efficiency, minimal heat loss, a compact and lightweight structure, a small footprint, wide application, and a long service life. Under the same pressure loss conditions, their heat transfer coefficient is 3-5 times higher than that of a tubular heat exchanger, requiring only one-third the floor space, and heat recovery rates can exceed 90%.

[0003] Plate heat exchangers are often used in air conditioning systems to regulate air temperature. Currently, the fixed structure of a plate heat exchanger is often designed for a single size.

[0034] See also Figure 1 An embodiment of the present invention provides a plate heat exchanger fixing structure for fixing a plate heat exchanger 40 , including: a chassis 10 , a protective shell 20 and a fixing bracket 30 , wherein the protective shell 20 and the fixing bracket 30 are arranged on the chassis 10 .

[0035] The chassis 10 is provided with a plurality of first fixing structures 11, and the plurality of first fixing structures 11 are arranged in sequence along a preset direction;

[0036] The fixing bracket 30 and the protective shell 20 are arranged in sequence along a preset direction, and a second fixing structure 21 is provided on the fixing bracket 30 or the protective shell 20. The fixing bracket 30 or the protective shell 20 is detachably connected to one of the first fixing structures 11 through the second fixing structure 21 to achieve a detachable connection with the chassis 10. By changing the first fixing structure 11 to which the second fixing structure 21 is connected to change the position of the fixing bracket 30 or the protective shell 20, the distance between the fixing bracket 30 and the protective shell 20 can be increased or decreased.

[0037] See also Figure 2 and Figure 3 The purpose of selectively detachably linking the first fixing structure 11 with the second fixing structure 21 is to enable the first fixing structure 11 to be connected to the second fixing structure 21 at different positions, thereby changing the position of the protective shell 20 or the fixing bracket 30. In this embodiment, the second fixing structure 21 is arranged on the protective shell 20. Of course, the principle of the second fixing structure 21 being arranged on the fixing bracket 30 is the same as the principle of the second fixing structure 21 being arranged on the protective shell 20, and the purpose is to adjust the distance between the fixing bracket 30 and the protective shell 20, so that the distance between the fixing bracket 30 and the protective shell 20 can adapt to plate heat exchangers 40 of different sizes. Figure 2 The larger plate heat exchanger 40 is installed in Figure 3 A plate heat exchanger 40 of smaller specifications is installed.

[0038] In some optional embodiments, the first fixing structure 11 includes a first threaded member mounting structure 12, the second fixing structure 21 includes a second threaded member mounting structure 22 and a plurality of first threaded members (not shown), and the first threaded member is detachably matched with the second threaded member mounting structure 22 and the first threaded member mounting structure 12 of one of the first fixing structures 11; and / or, the first fixing structure 11 includes a first snap-fit ​​structure 13, the second fixing structure 21 includes a second snap-fit ​​structure 23, and the first snap-fit ​​structure 13 is detachably matched with the second snap-fit ​​structure 23.

[0039] The first fixing structure 11 may include only the first threaded mounting structure 12, and the second fixing structure 21 may include only the second threaded mounting structure 22 and the first threaded member; alternatively, the first fixing structure 11 may include only the first snap-fit ​​structure 13, and the second snap-fit ​​structure 23 may include only the second snap-fit ​​structure 23. In this embodiment, the first fixing structure 11 includes both the first threaded mounting structure 12 and the first snap-fit ​​structure 13, and the second fixing structure 21 includes both the second threaded mounting structure 22, the first threaded member, and the second snap-fit ​​structure 23. The connection achieved through two different structures facilitates improved stability of the direct connection between the fixing bracket 30 or protective case 20 and the chassis 10.

[0040] See also Figure 4 and Figure 5 In some optional embodiments, the first threaded mounting structure includes a plurality of first mounting holes 121 provided on the chassis 10, the second threaded mounting structure includes a plurality of second mounting holes 221, the second mounting holes 221 are correspondingly connected to the first mounting holes 121 of one of the first fixing structures 11, the plurality of second mounting holes 221 are respectively provided on at least two sides of the fixing bracket 30 or at least two sides of the protective shell 20, and the first threaded member is correspondingly passed through the second mounting holes 221 and the first mounting holes 121 of one of the first fixing structures 11; the first snap-fit ​​structure 13 includes a plurality of snap-fit ​​holes 131 provided on the chassis 10, the second snap-fit ​​structure 23 includes a plurality of snap-fit ​​members 231, the two snap-fit ​​members 231 are respectively provided on at least two sides of the fixing bracket 30 or at least two sides of the protective shell 20, and the snap-fit ​​members 231 are snap-fitted with the snap-fit ​​holes 131 of one of the first fixing structures 11.

[0041] In this embodiment, the first mounting holes 121 of the first fixing structure 11 are correspondingly located on the left and right sides and the rear side of the protective shell 20, and the first mounting holes 121 of each first fixing structure 11 are arranged in sequence corresponding to the preset installation direction. For example, the first mounting holes 121 of each first fixing structure 11 on the left side of the protective shell 20 are arranged in sequence along the preset direction, and the first mounting holes 121 of each first fixing structure 11 on the right side of the protective shell 20 are arranged in sequence along the preset direction; the plurality of second mounting holes 221 are respectively provided on the left and right sides and the rear side of the protective shell 20, and the number of the first screw members is the same as that of the first screw members 221. The number of second mounting holes 221 corresponds to the number of second mounting holes 221. The first threaded member locks multiple sides of the protective shell 20, thereby improving the stability of the protective shell 20 when installed on the chassis 10. Clips 231 are arranged on the left and right sides of the protective shell 20, respectively. Multiple clips 231 lock the two sides of the protective shell 20, thereby improving the stability of the protective shell 20 when installed on the chassis 10. Moreover, during installation, the clips 231 first snap together with the clip holes 131 to pre-lock the protective shell 20. This then makes it easier for the protective shell 20 to shift position during the subsequent installation of the first threaded member, thereby facilitating the installation operation. Of course, in other embodiments, the second mounting holes 221 can also be arranged only on the rear side or left and right sides of the protective shell 20, and the clips 231 can also be arranged only on the rear side of the protective shell 20. Among them, the first threaded member can be threadedly matched with the first mounting hole 121 or the second mounting hole 221, so that the first threaded member can lock the protective shell 20 and the chassis 10. The first threaded member can also cooperate with the nut to clamp the protective shell 20 and the chassis 10.

[0042] In addition, when the second mounting hole 221 and the locking member 231 are provided on the fixing bracket 30 , the principle is the same as above.

[0043] Of course, the structures of the first fixing structure 11 and the second fixing structure 21 are not limited to this. Those skilled in the art may also choose other suitable structures according to the teachings of the present invention. For example, the first fixing structure 11 may also include a pressure plate rotatably set on the chassis 10, and the second fixing structure 21 includes a groove set on the fixing bracket 30 or the protective shell 20. After the pressure plate is rotated, it is clamped into the groove to fix the fixing bracket 30 or the protective shell 20. When disassembling, the pressure plate can be rotated out of the groove; or, the first fixing structure 11 includes a convex buckle set on the chassis 10, and the second fixing structure 21 includes a buckle groove set on the fixing bracket 30 or the protective shell 20. The convex buckle is clamped into the buckle groove, which can also fix the fixing bracket 30 or the protective shell 20.

[0044] In some optional embodiments, when the second fixing structure 21 is provided on the protective shell 20, the fixing bracket 30 is detachably connected to the chassis 10 through a threaded structure and / or a snap structure; when the second fixing structure 21 is provided on the fixing bracket 30, the protective shell 20 is detachably connected to the chassis 10 through a threaded structure and / or a snap structure, thereby facilitating the installation of the plate heat exchanger 40. During installation, the plate heat exchanger 40 is first placed in a suitable installation position on the chassis 10, and then the fixing bracket 30 and the protective shell 20 are installed to fix the plate heat exchanger 40.

[0045] In this embodiment, the second fixing structure 21 is arranged on the protective shell 20, and the fixing bracket 30 is detachably connected to the chassis 10 through a threaded structure and / or a snap-fit ​​structure. The specific structure of the threaded structure and / or the snap-fit ​​structure can be designed according to actual needs. For example, the threaded structure includes a screw (not shown), a first screw hole 14 arranged on the chassis 10, and a second screw hole 34 arranged on the fixing bracket. The screw is threadedly engaged with the first screw hole 14 or the second screw hole 34 to achieve locking of the chassis 10 and the fixing bracket 30. The bolt can also be used in conjunction with a nut to complete the locking of the chassis 10 and the fixing bracket 30; the snap-fit ​​structure may include a snap-fit ​​portion 15 arranged on the chassis 10 and a buckle position 35 arranged on the fixing bracket 30, and the snap-fit ​​portion 15 is snap-fitted with the buckle position 35.

[0046] In order to improve the overall structural stability, in some optional embodiments, the fixing bracket 30 and the protective shell 20 are detachably connected. At this time, the chassis 10, the fixing bracket 30 and the protective shell 20 are interconnected, and the plate heat exchanger 40 can be stably fixed.

[0047] See also Figure 1 and Figure 6 The detachable connection method between the fixing bracket 30 and the protective shell 20 can be designed according to actual needs. For example, in some optional embodiments, the fixing bracket 30 is provided with a plurality of third mounting holes 31 arranged in sequence along a preset direction, the protective shell 20 is provided with a fourth mounting hole 24, and the fixing bracket 30 is further provided with a second threaded member that passes through the third mounting hole 31 and the fourth mounting hole 24. The second threaded member can be threadedly engaged with the third mounting hole 31 or the fourth mounting hole 24, thereby achieving the locking of the protective shell 20 and the chassis 10 by the first threaded member. The second threaded member can also cooperate with a nut to clamp the protective shell 20 and the chassis 10. In this embodiment, the plate heat exchanger 40 is further provided with a fifth mounting hole 41. The second threaded member passes through the third mounting hole 31 and the fourth mounting hole 24, and then threadedly engages with the fifth mounting hole 41, thereby locking the fixing bracket 30, the protective shell 20 and the plate heat exchanger 40 to each other. Of course, the second threaded member can also cooperate with the nut to clamp and lock the fixing bracket 30, the protective shell 20 and the plate heat exchanger 40 together.

[0048] The preset direction can be determined according to actual installation requirements. In this embodiment, the preset direction is the front-to-back direction of the chassis 10 , the fixing bracket 30 is located on the front side of the plate heat exchanger 40 , and the protective shell 20 is located on the rear side of the plate heat exchanger 40 .

[0049] The specific structure of the fixing bracket 30 can be designed according to actual needs. For example, in some optional embodiments, the fixing bracket 30 includes side frames 32 and a top frame 33. The top frame 33 is arranged on the top of the side frames 32 and extends in a predetermined direction. The side frames 32 are arranged on the chassis 10, and the top frame 33 is detachably connected to the top of the protective shell 20. This interconnects the chassis 10, the fixing bracket 30, and the protective shell 20, thereby stably fixing the plate heat exchanger 40. The side frames 32 are restricted to the front side of the plate heat exchanger 40, while the top frame 33 is restricted to the top of the plate heat exchanger 40, thereby enabling the fixing bracket 30 to stably restrain the plate heat exchanger 40.

[0050] The specific structure of the protective shell 20 can be designed according to actual needs. For example, in some optional embodiments, the protective shell 20 includes a first side baffle 25 and two second side baffles 26. The first side baffle 25 is arranged on the chassis 10, and the two second side baffles 26 are respectively arranged on both sides of the first side baffle 25 in a preset direction. A limiting flange 27 is provided on the top of the first side baffle 25 and / or the two second side baffles 26. The first side baffle 25 is restrained on the rear side of the plate heat exchanger 40, the two second side baffles 26 are restrained on the left and right sides of the plate heat exchanger 40, and the limiting flange 27 is restrained on the top of the plate heat exchanger 40, thereby enabling the fixing bracket 30 to stably restrain the plate heat exchanger 40. Due to the semi-enclosed structure of the protective shell 20, the top, rear, left, and right sides of the plate heat exchanger 40 are all restrained. In conjunction with the fixing bracket 30 restraining the front side of the plate heat exchanger 40 and the chassis 10 supporting and restraining the bottom of the plate heat exchanger 40, the plate heat exchanger 40 can be restrained in all directions, improving the fixing stability of the plate heat exchanger 40. In this embodiment, the top frame 33 of the fixing bracket 30 is connected to the limiting flange 27 of the first side baffle 25, thereby improving the stability of the limiting flange 27 in restraining the plate heat exchanger 40.

[0051] The above-mentioned plate heat exchanger fixing structure can be applied to air conditioning equipment, which includes: a plate heat exchanger 40 and a plate heat exchanger fixing structure as described above, the plate heat exchanger 40 is arranged on the chassis 10 and is confined between the fixing bracket 30 and the protective shell 20.
