Description

Technical Field

[0001] This application relates to, but is not limited to, the field of heat pump equipment technology, specifically to a support component, an outdoor unit of a hot and cold water unit, and the hot and cold water unit itself. Background Technology

[0002] An outdoor unit for a hot and cold water chiller includes a first chassis, a partition, a first support beam, a second support beam, a second chassis, and a compressor. The second support beam includes a vertical beam and a horizontal beam. The first support beam is located in front of the vertical beam. The first chassis is horizontally arranged. The partition is erected on the first chassis along the front-rear direction. The first support beam and the vertical beam are both erected on the first chassis to the right of the first partition. A rearwardly protruding overlapping plate is provided on the rear side of the first support beam. The rear end of the horizontal beam is fixedly connected to the upper end of the vertical beam, and the front end of the horizontal beam overlaps downwards on and is fixedly connected to the overlapping plate. The upper end of the partition, the upper end of the first support beam, and the upper rear part of the horizontal beam support the second chassis and are fixedly connected to it. The compressor is fixed inside the second chassis.

[0003] During drop tests, the crossbeam of this outdoor unit is prone to tilting downwards and bending the overlapping plate under the impact of the compressor and the second chassis. This causes the crossbeam to tilt downwards from back to front, and the upper end of the vertical beam to bend forward. Consequently, the right rear end of the second chassis and the right rear end of the compressor will tilt downwards. Therefore, the outdoor unit provided by this design cannot guarantee the reliability of compressor support during drop tests, and will also cause a decrease in the operational reliability of the compressor and an increase in the operating noise of the outdoor unit.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0041] The outdoor unit of the chilled and hot water unit provided in this application embodiment, such as Figures 1 to 18 As shown, it includes: a first chassis 100; a partition 200; a second support beam 300 and a support assembly 400; a second chassis 500; and a compressor 600. The second support beam 300 includes a vertical beam 310 and a horizontal beam 320 connected to each other. Figure 17 and Figure 18 As shown, the support assembly 400 includes: a first support beam 410, the first support beam 410 having a protruding overlapping fit portion 411 on its first side; and a reinforcing member 420, the reinforcing member 420 being fixed to the first support beam 410 and having a supporting portion 421, the supporting portion 421 being located on the first side of the first support beam 410 and abutting against the overlapping fit portion 411 in the supporting direction of the first support beam 410. Wherein: Figures 1 to 3 , Figure 5 As shown, the partition 200, vertical beam 310, and first support beam 410 are erected sequentially along the circumference of the first chassis 100 (erected generally in the vertical direction) on the first chassis 100 (the first chassis 100 is generally horizontal). One end of the crossbeam 320 is connected to the end of the vertical beam 310 away from the first chassis 100, and the other end of the crossbeam 320 (downward) overlaps with and is fixed to the overlapping fitting part 411 (e.g., ...). Figure 3 , Figure 5 , Figure 7 , Figure 9 , Figure 11 , Figure 13 , Figure 17 and Figure 18 (As shown). The second chassis 500 is fixed to the end of the partition 200 away from the first chassis 100, the end of the crossbeam 320 away from the first chassis 100, and the end of the first support beam 410 away from the first chassis 100. The support part 421 is located between the overlapping part 411 and the first chassis 100. The support direction includes the direction from the first chassis 100 to the second chassis 500 and the direction from the second chassis 500 to the first chassis 100 (for the arrangement where the second chassis 500 is above the first chassis 100, the support direction is vertical). The compressor 600 is located on the second chassis 500 (e.g., Figure 1 (As shown).

[0042] In this outdoor unit, the end of the crossbeam 320 furthest from the vertical beam 310 overlaps downwards onto the overlapping mating part 411. The support part 421 supports the overlapping mating part 411 from below. This combination of support part 421 and overlapping mating part 411 results in higher structural strength. During drop tests, the combination of support part 421 and overlapping mating part 411 can stably support the end of the crossbeam 320 furthest from the vertical beam 310. The combination of support part 421 and overlapping mating part 411 will not tilt downwards, and the vertical beam 310 will not bend. Therefore, during drop tests, the compressor 600 exhibits good support reliability and operational reliability, and the outdoor unit operates with low noise.

[0043] In one embodiment, such as Figure 3 , Figure 5 , Figure 7 , Figure 9 , Figure 11 , Figure 13 , Figure 17 and Figure 18 As shown, the first chassis 100 is generally rectangular and arranged horizontally. The length direction of the first chassis 100 is the left-right direction, and the width direction of the first chassis 100 is the up-down direction. The partition 200 is erected at the left end of the first chassis 100 along the front-back direction. The vertical beam 310 is erected at the right rear end of the first chassis 100 along the left-right direction. The first support beam 410 is erected at the right front end of the first chassis 100 along the left-right direction. The horizontal beam 320 is arranged horizontally along the front-back direction. The rear end of the horizontal beam 320 is fixedly connected to the upper end of the vertical beam 310. The front end of the horizontal beam 320 overlaps downward with the overlapping fitting part 411 and is fixedly connected to the overlapping fitting part 411. The compressor 600 is located inside the second chassis 500. The second chassis 500 is located above the partition 200, the first support beam 410 and the horizontal beam 320. The bottom wall of the second chassis 500 is fixedly connected to the upper end of the partition 200, the upper end of the first support beam 410 and the upper end of the horizontal beam 320. The partition 200, the first support beam 410 and the horizontal beam 320 support the second chassis 500 and the compressor 600. The support direction is vertical, and the first side is the rear side.

[0044] In some examples, such as Figure 17 and Figure 18 As shown, the reinforcing member 420 also has a first connecting portion 422, and the first support beam 410 also has a second connecting portion 412. The first connecting portion 422 is located behind the second connecting portion 412 and is fixedly connected to the second connecting portion 412, thereby fixing the reinforcing member 420 to the rear side of the first support beam 410. This can be, for example... Figure 17 and Figure 18As shown, the first connecting part 422 is a first screw hole, and the second connecting part 412 is a second screw hole. The first screw hole and the second screw hole are fixed together by a first screw; or the first connecting part 422 is a first welding position, and the second connecting part 412 is a second welding position, and the first welding position and the second welding position are welded together, etc. All of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model. They will not be elaborated here, and all should fall within the protection scope of this application.

[0045] In some examples, such as Figure 17 and Figure 18 As shown, one of the first support beam 410 and the reinforcing member 420 also has a plug-in portion 423, and the other has a plug-in mating portion 413. The plug-in portion 423 and the plug-in mating portion 413 are plugged together in a second direction intersecting the support direction of the first support beam 410, which is used to restrict the movement of the reinforcing member 420 along the support direction of the first support beam 410. The first connecting portion 422 is a first screw hole, and the second connecting portion 412 is a second screw hole. The first screw hole and the second screw hole are fixed together by a first screw. The mating structure of the plug-in portion 423 and the plug-in mating portion 413 in this scheme allows the first support beam 410 to support the reinforcing member 420 upwards, thereby reducing or even eliminating the downward shear force on the first screw (the shear force is the downward pressure formed by the overlapping mating portion 411 pressing down on the support portion 421, which is relatively large when the outdoor unit is subjected to drop tests). In this way, the first screw is less likely to be sheared by the downward shear force.

[0046] In some embodiments, such as Figure 17 and Figure 18 As shown, one of the insertion part 423 and the insertion mating part 413 is a first insertion rib, and the other is a first insertion hole. The first insertion rib and the first insertion hole have simple structures and are easy to manufacture. The second direction intersects perpendicularly with the support direction, and the second direction is the front-to-back direction. It could be, for example... Figure 17 and Figure 18 As shown, the reinforcing member 420 has a first insert rib protruding forward, and the rear side of the first support beam 410 is provided with a first insertion hole, and the first insert rib is inserted forward into the first insertion hole.

[0047] In some examples, such as Figure 7 , Figure 9 , Figure 11 , Figure 17 and Figure 18As shown, the overlapping mating part 411 is a horizontally arranged overlapping mating plate, and the supporting part 421 is a horizontally arranged supporting plate. The lower surface of the overlapping mating plate and the upper surface of the supporting plate are arranged opposite each other vertically. The overlapping mating plate has a third screw hole 4111 and a second insertion hole 4112. The supporting plate has a mating hole 4211 and a clearance hole 4212. The third screw hole 4111 and the mating hole 4211 are arranged opposite each other in the vertical direction, and the second insertion hole 4112 and the clearance hole 4212 are arranged opposite each other in the vertical direction. The front end of the crossbeam 320 has a forward-protruding overlapping plate 321, which has an eighth screw hole 3211 and a third insertion rib 3212. The overlapping plate 321 rests downward on the overlapping mating plate. The third insert rib 3212 is inserted into the second insert hole 4112 and the clearance hole 4212. The third screw passes through the eighth screw hole 3211 (such as a through hole) and is screwed into the third screw hole 4111 (such as a screw hole). The lower part of the third screw passes through the mating hole 4211 (such as a through hole or a screw hole; for technical solutions where the mating hole 4211 is a through hole, the mating hole 4211 is used to avoid the lower part of the third screw).

[0048] Better, such as Figure 7 , Figure 9 and Figure 11 As shown, the left side of the third insert 3212 has a set of third screw holes 4111, mating holes 4211 and eighth screw holes 3211, and the right side of the third insert 3212 also has a set of third screw holes 4111, mating holes 4211 and eighth screw holes 3211.

[0049] Better, such as Figure 3 and Figure 9 As shown, the front end of the crossbeam 320 on the rear side of the lap plate 321 ( Figure 9 The lap joint plate (position a) is also supported on the lap joint plate, so the lap joint plate 321 is less likely to bend under impact, and the lap joint reliability of the crossbeam 320 and the support component 400 is better.

[0050] In some examples, such as Figure 3 , Figure 17 and Figure 18As shown, the first end and the second end of the first support beam 410 correspond to the upper end and lower end of the first support beam 410, respectively. The overlapping mating part 411 is located between the upper end of the first support beam 410 and the support part 421. The upper end face of the first support beam 410 has a fifth screw hole and an upwardly protruding second insert rib 416, while the lower end face of the first support beam 410 has a first hook hole 417. The bottom wall of the second chassis 500 has a fourth insertion hole 510. The second insert rib 416 is inserted upwards into the fourth insertion hole 510 to pre-position the second chassis 500. A fourth screw passes through the bottom wall of the second chassis 500 and is screwed into the fifth screw hole, thus fixing the second chassis 500 to the first support beam 410. Figure 5 , Figure 6 , Figure 17 and Figure 18 As shown, the bottom wall of the first chassis 100 has a first hook 110, and a first slot with an opening facing left is formed between the first hook 110 and the bottom wall of the first chassis 100. The first hook 110 extends into the first hook hole 417, and then the first support beam 410 is moved to the right so that the first hook 110 is hooked on the left side wall of the first hook hole 417. Then, the fifth screw passes through the side wall of the first chassis 100 and is screwed onto the first support beam 410, so that the first support beam 410 and the first chassis 100 are fixedly connected together.

[0051] In some embodiments, such as Figure 6 , Figure 17 and Figure 18 As shown, the first support beam 410 includes a second plate 4182, a first plate 4181, and a third plate 4183 connected in sequence. The first plate 4181 is erected vertically in the left-right direction, the second plate 4182 is erected vertically in the front-back direction, and the third plate 4183 is erected vertically in the front-back direction. The second plate 4182 and the third plate 4183 are located behind the first plate 4181, and the second plate 4182 is located to the left of the third plate 4183. The right surface of the second plate 4182 and the left surface of the third plate 4183 are opposite to each other. The rear ends of the second plate 4182 and the rear ends of the third plate 4183 have first reinforcing flanges 4184 that bend in opposite directions. Figure 17 and Figure 18As shown, each first reinforcing flange 4184 has a first insertion hole, and the two first insertion holes are connected on opposite sides. The left and right ends of the first insertion rod are inserted into the two first insertion holes from back to front. The first plate 4181 is fixed to the side wall of the first chassis 100 by a fifth screw. The reinforcing member 420 includes a support plate, a connecting plate 424 and a first insertion rod connected in sequence. The connecting plate 424 is erected in the left and right direction. The first insertion rod and the support plate are located on the front and rear sides of the connecting plate 424, and the first insertion rod is arranged horizontally. The first connecting part 422 (such as the first screw hole) is located on the connecting plate 424 (the connecting plate 424 is provided with two sets of first connecting parts 422, and each first reinforcing flange 4184 is provided with a set of second connecting parts 412, and the two sets of first connecting parts 422 and the two sets of second connecting parts 412 correspond one-to-one). The first reinforcing fold 4184 can not only improve the structural strength of the first support beam 410, but also prevent the rear end of the second plate 4182 and the rear end of the third plate 4183 from cutting the wiring.

[0052] In some embodiments, such as Figure 17 and Figure 18 As shown, the upper end of the first plate 4181 has a first folded edge 4191 formed by bending backward, a second folded edge 4192 formed by bending downward, and an overlapping mating plate formed by bending towards the rear side of the second folded edge 4192. The second folded edge 4192 connects the first folded edge 4191 and the overlapping mating plate. The lower side of the first folded edge 4191 abuts against the upper end face of the second plate 4182, the upper end face of the third plate 4183, and the upper end faces of the two first reinforcing folded edges 4184. The second folded edge 4192 is located behind the two first reinforcing folded edges 4184 and is fixedly connected to the two first reinforcing folded edges 4184 to avoid the second folded edge 4192 from tilting backward relative to the two first reinforcing folded edges 4184 when the first support beam 410 is manufactured by stamping process.

[0053] It can be, such as Figure 18 As shown, both first reinforcing folds 4184 are also provided with a seventh screw hole 4193, and the second fold 4192 is provided with two sixth screw holes 4194. The two seventh screw holes 4193 and the two sixth screw holes 4194 correspond one-to-one and are fixed together by two second screws, so that the second fold 4192 is fixed on the two first reinforcing folds 4184; or the second fold 4192 and the two first reinforcing folds 4184 can be connected by welding or other methods; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model, so they will not be elaborated here, and all should fall within the protection scope of this application.

[0054] In some embodiments, such as Figure 17 and Figure 18As shown, the lower end of the first plate 4181 is bent backward to form a third folded edge 4195. The upper side of the third folded edge 4195 abuts against the lower end face of the second plate 4182, the lower side of the third plate 4183, and the lower end faces of the two first reinforcing folded edges 4184. The first hook hole 417 is located on the third folded edge 4195 and between the second plate 4182 and the third plate 4183.

[0055] In some examples, such as Figure 4 , Figure 8 , Figure 11 and Figure 13 As shown, the vertical beam 310 includes a fifth plate 312, a fourth plate 311, and a sixth plate 313 connected in sequence. The fourth plate 311 is erected vertically in the left-right direction. The fifth plate 312 and the sixth plate 313 are located in front of the fourth plate 311 and are both erected vertically in the front-back direction. The fifth plate 312 and the sixth plate 313 are arranged opposite each other in the left-right direction. The front ends of the fifth plate 312 and the sixth plate 313 are provided with second reinforcing folds that bend in opposite directions. Edge 314, the lower end of the fourth plate 311 is provided with a forward-bent fourth folded edge 315, the upper side of the fourth folded edge 315 abuts against the lower end face of the fifth plate 312, the lower end face of the sixth plate 313 and the lower end faces of the two second reinforcing folded edges 314, the front end of the fourth folded edge 315 is provided with a downward-bent fourth insert rib 316, the bottom wall of the first base 100 is provided with a fifth insertion hole 120, and the fourth insert rib 316 is inserted downward into the fifth insertion hole 120 (e.g. Figure 4 As shown, a pre-positioned vertical beam 310 is achieved on the first chassis 100, and then the fourth plate 311 is fixed to the side wall of the first chassis 100 by a sixth screw, thus fixing the vertical beam 310 and the first chassis 100 together. The second reinforcing fold 314 not only improves the structural strength of the vertical beam 310, but also prevents the front end of the fifth plate 312 and the front end of the sixth plate 313 from cutting the wiring.

[0056] like Figure 3 , Figure 7 , Figure 9 , Figure 11 , Figure 13 and Figure 16As shown, the crossbeam 320 includes an eighth plate 323, a seventh plate 322, and a ninth plate 324 connected in sequence. The seventh plate 322 is arranged horizontally in the front-to-back direction. The eighth plate 323 and the ninth plate 324 are located below the seventh plate 322 and are erected in the front-to-back direction. The lower ends of the eighth plate 323 and the ninth plate 324 have third reinforcing folds 325 that bend towards each other. The upper end of the fifth plate 312 has a first inclined edge 3122 extending downward from back to front and a first horizontal edge 3121 extending forward from back to front. The rear end of the first horizontal edge 3121 is connected to the lower front end of the first inclined edge 3122. Next, the rear end of the eighth plate 323 has a second inclined side 3231 extending downward from back to front. The second inclined side 3231 cooperates with the first inclined side 3122. The rear part of the lower end face of the eighth plate 323 is supported on the first horizontal side 3121, thus supporting the rear part of the eighth plate 323. The cooperation structure of the sixth plate 313 and the ninth plate 324 is the same as that of the fifth plate 312 and the eighth plate 323, and will not be described again here. In the above scheme, the vertical beam 310 provides better support for the horizontal beam 320, and the horizontal beam 320 is less likely to bend downward from back to front relative to the vertical beam 310. Figure 7 , Figure 9 and Figure 11 As shown, the front end of the seventh plate 322 has a fifth folded edge 3221 formed by bending downward, an overlapping plate 321 formed by extending horizontally from back to front, and a third insert rib 3212 formed by bending downward from top to bottom. The overlapping plate 321 (the overlapping plate 321 rests downward on the overlapping mating plate) connects the fifth folded edge 3221 and the third insert rib 3212 (the third insert rib 3212 is inserted into the second insertion hole 4112 and the clearance hole 4212). The eighth screw hole 3211 is located on the overlapping plate 321. The rear side of the fifth folded edge 3221 abuts against the front end face of the eighth plate 323 and the front end face of the ninth plate 324. The front part of the lower end face of the eighth plate 323 and the front part of the lower end face of the ninth plate 324 also rest downward on the overlapping mating plate. In this way, the overlapping plate 321 is not easy to bend and tilt when subjected to impact, and the overlapping reliability of the crossbeam 320 and the support assembly 400 is better. The third reinforcing fold 325 not only improves the structural strength of the crossbeam 320, but also prevents the lower ends of the eighth plate 323 and the ninth plate 324 from cutting the wiring.

[0057] In some embodiments, such as Figures 1 to 3 , Figure 5 , Figure 7 , Figure 11 , Figure 13 , Figure 14As shown, the outdoor unit also includes a fixed bracket 710, a reinforcing bracket 720, and a heat exchanger bracket 730. The front and rear ends of the fixed bracket 710 (e.g., welded) are fixed to the top surface of the first plate 4181. The middle part of the fixed bracket 710 protrudes upwards, and the middle part of the fixed bracket 710 also has an upwardly protruding fifth insert rib 711 and a ninth screw hole (e.g. Figure 2 , Figure 3 , Figure 11 and Figure 14 As shown), the right rear end of the bottom wall of the second chassis 500 is provided with a sixth insertion hole 520. The fifth insertion rib 711 is inserted upward into the sixth insertion hole 520, and the seventh screw passes through the bottom wall of the second chassis 500 and is screwed into the ninth screw hole, thereby achieving a fixed connection between the right rear end of the second chassis 500 and the fixed bracket 710 fixed on the crossbeam 320. Figure 3 and Figure 13 As shown, the reinforcing bracket 720 is triangular in shape and fixed to the right side of the connection between the horizontal beam 320 and the vertical beam 310, used to improve the connection strength between the horizontal beam 320 and the vertical beam 310. Figure 11 , Figure 13 and Figure 14 As shown, the upper part of the reinforcing bracket 720 protrudes upward from the seventh plate 322 of the crossbeam 320. The plate replacement bracket 730 is placed above the rear side of the seventh plate 322 and is fixed to the reinforcing bracket 720 and the seventh plate 322 by the eighth screw. Figure 3 and Figure 13 As shown, a metal-plastic strip 740 for fixing the cable routing is welded to the front right side of the crossbeam 320. This could be, for example... Figure 14 and Figure 15 As shown, the lower end of the plate-mounted heat exchanger bracket 730 has a downwardly protruding second hook 731. A second slot with a forward-facing opening is formed between the second hook 731 and the plate-mounted heat exchanger bracket 730. The seventh plate 322 has a second hook-in hole. The second hook 731 extends into the second hook-in hole. Then, the plate-mounted heat exchanger bracket 730 is moved forward, causing the second hook 731 to hook onto the front wall of the second hook-in hole, thus pre-positioning the plate-mounted heat exchanger bracket 730 on the seventh plate 322. This facilitates the screwing on of the eighth screw. (The last sentence appears to be an unrelated fragment and is omitted from the translation.) Figure 7 , Figure 10 and Figure 16 As shown, the reinforcing bracket 720 has a seventh insert rib 721 protruding to the left. The right side of the second support beam 300 (such as the vertical beam 310) is provided with a seventh insertion hole. The seventh insert rib 721 is inserted into the seventh insertion hole to the left, so that the reinforcing bracket 720 is pre-positioned on the second support beam 300. This makes it easier to fix the reinforcing bracket 720 on the second support beam 300.

[0058] like Figure 3As shown, the upper part of the partition 200 has a sixth folded edge that bends to the right. The sixth folded edge has a sixth rib 210 that protrudes upward and a tenth screw hole. The left end of the bottom wall of the second chassis 500 has an eighth insertion hole 530. The sixth rib 210 is inserted upward into the eighth insertion hole 530. Then, the ninth screw passes through the bottom wall of the second chassis 500 and is screwed into the tenth screw hole, so that the second chassis 500 and the partition 200 are fixedly connected together.

[0059] Among them, such as Figure 2 As shown, the top surface of the fifth insert 711 is higher than the top surface of the sixth insert 210, and the top surface of the fifth insert 711 is also higher than the top surface of the second insert 416. When installing the second chassis 500, first insert the fifth insert 711 into the sixth socket 520, then insert the second insert 416 into the fourth socket 510, and the sixth insert 210 into the eighth socket 530; then, first screw on the ninth screw and the fourth screw, and then screw on the seventh screw. This prevents the right rear part of the second chassis 500 from tilting upwards when screwing on the ninth screw and the fourth screw, causing the sixth socket 520 to detach upwards from the fifth insert 711.

[0060] In some embodiments, such as Figures 1 to 3 As shown, the outdoor unit also includes a third chassis 800 and a shell-and-tube heat exchanger 900. The second chassis 500 is located inside the third chassis 800, and the shell-and-tube heat exchanger 900 is located between the first chassis 100 and the second chassis 500.

[0062] This hot and cold water unit possesses all the advantages of the outdoor unit of the hot and cold water unit provided in any of the above embodiments, which will not be repeated here.

[0063] In summary, the outdoor unit of the chilled water unit provided in this application embodiment has a second support beam whose horizontal beam, away from the vertical beam, overlaps downwards onto the overlapping mating part. The support part supports the overlapping mating part from below. This combination of support part and overlapping mating part results in higher structural strength. During drop tests, the combination of support part and overlapping mating part can stably support the horizontal beam away from the vertical beam upwards without tilting downwards or bending the vertical beam. Therefore, the outdoor unit of this chilled water unit exhibits good compressor support reliability and operational reliability during drop tests, and the outdoor unit operates with low noise.
