Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and specifically provides a heat exchanger anti-collision component, a heat exchanger and a mobile air conditioner. Background Art

[0002] Currently, both wall-mounted and floor-standing air conditioners must be fixed in a defined location and cannot be moved. Therefore, mobile air conditioners have emerged. Mobile air conditioners primarily include a housing, an indoor air circulation assembly, and an outdoor air circulation assembly. Both the indoor and outdoor air circulation assemblies are housed within the housing, and the housing is provided with indoor air inlets and outlets corresponding to the indoor air circulation assembly. The housing also includes outdoor air inlets and outlets corresponding to the outdoor air circulation assembly. Due to their small size, mobile air conditioners can be moved to different locations or rooms to adjust the air temperature there.

[0003] In the mobile air conditioner of the related art, an outdoor heat exchanger and a compressor are arranged in the outdoor heat exchange chamber, and the outdoor heat exchanger and the compressor are both fixed to the base. Usually, the compressor is fixed to the base in a rocking manner through a vibration-damping plate to reduce the vibration force transmitted to the base when the compressor is running. However, due to the limited internal space of the mobile air conditioner, the distance between the compressor and the outdoor heat exchanger is relatively close. When the mobile air conditioner is transported or the compressor shakes a large amplitude, the compressor will tilt, causing the compressor to press against the outdoor heat exchanger, and the fins of the outdoor heat exchanger will be squeezed and deformed or inverted, resulting in a decrease in the heat exchange effect of the outdoor heat exchanger. Utility Model Content

[0004] The utility model aims to solve the above technical problem, that is, to solve the problem that the heat exchanger is easily damaged by the compressor.

[0005] In a first aspect, the utility model provides a heat exchanger anti-collision component, comprising: an anti-collision strip, comprising a first side surface and a second side surface, wherein the anti-collision strip is recessed from the first side surface toward the second side surface to form an arc-shaped recessed portion, wherein the arc-shaped recessed portion is configured so that the convex surface faces the heat exchanger when it is installed to the heat exchanger.

[0006] When adopting the above technical solution, by recessing the second side of the anti-collision strip toward the first side to form an arcuate recess, the arcuate recess can contact the heat exchanger when the compressor tilts toward the heat exchanger and strikes the anti-collision strip. This reduces the width of the anti-collision strip while allowing the arcuate surface to contact the heat exchanger fins. This not only effectively disperses and cushions the impact force, but also prevents damage or severing of the heat exchange fins, thereby improving the safety of the heat exchanger.

[0007] In an optional embodiment of the heat exchanger anti-collision member, the arc-shaped recessed portion extends along the length direction of the anti-collision strip.

[0008] By providing an arc-shaped recessed portion extending along the length direction of the anti-collision strip, the impact force on the anti-collision strip can be more effectively dispersed along the length direction of the arc-shaped recessed portion, thereby reducing local stress concentration and thus reducing direct damage to the heat exchanger.

[0009] In an optional implementation scheme of the heat exchanger anti-collision component, the heat exchanger anti-collision component further includes: a flexible buffer component, which is arranged on the first side surface.

[0010] By providing the flexible buffer, when the compressor tilts and impacts the anti-collision strip, the impact of the compressor can be buffered, thereby preventing the anti-collision strip from being deformed or damaged.

[0011] In an optional embodiment of the above-mentioned heat exchanger anti-collision member, the arc-shaped recessed portion has an arc-shaped groove, the flexible buffer member is arranged in the arc-shaped groove and at least partially extends out of the arc-shaped groove; and / or, the flexible buffer member is arranged circumferentially around the arc-shaped groove.

[0012] Such an arrangement can improve the safety of the anti-collision strip and prevent deformation or damage when it is hit by the compressor.

[0013] In an optional embodiment of the heat exchanger anti-collision member, the flexible buffer member includes one or more of a sponge member, an elastic rubber member or an elastic plastic member.

[0014] Sponge has excellent deformation and resilience properties, making it suitable for use as a cushioning material. Sponge also has a low density and is lightweight, requiring minimal load-bearing capacity. Elastic rubber components offer excellent wear and heat resistance, making them suitable for use as flexible cushioning components. Elastic plastic components offer both good elastic deformation and wear resistance.

[0015] In a second aspect, the utility model provides a heat exchanger, comprising: a heat exchange main body, the heat exchange main body comprising at least a first tube group, the first tube group comprising a plurality of heat exchange tubes arranged at intervals along the vertical direction; and, a heat exchanger anti-collision member as described above, wherein the arc-shaped recessed portion is arranged toward the first tube group and is located between two adjacent heat exchange tubes.

[0016] When the above technical solution is adopted, by making the second side surface of the anti-collision strip concave toward the first side surface to form an arc-shaped recessed portion, and arranging the arc-shaped convex surface of the arc-shaped recessed portion between two adjacent heat exchange tubes, when the compressor tilts toward the first tube group and hits the anti-collision strip, the arc-shaped recessed portion can be squeezed and stuck between the two heat exchange tubes. The setting of the arc surface can avoid cutting or breaking the heat exchange tubes.

[0017] In an optional embodiment of the above-mentioned heat exchanger, the heat exchange body also includes a first side end and a second side end extending vertically and located at both ends of the first tube group; the anti-collision strip includes a first fixed end and a second fixed end; the first fixed end corresponds to a detachable connection with the first side end, and the second fixed end corresponds to a detachable connection with the second side end.

[0018] By making the first fixed end detachably connected to the first side end and the second fixed end detachably connected to the second side end, the flexibility of installing or removing the heat exchanger anti-collision component can be improved.

[0019] In an optional embodiment of the above-mentioned heat exchanger, the first side end is fastened and connected to a tube sheet, the tube sheet is provided with a receiving groove, the first fixed end is provided with a first bent section bent toward the heat exchange body, the first bent section is inserted into the receiving groove, and is connected to the tube sheet screw.

[0020] The accommodating groove provided on the tube sheet can, on the one hand, play a positioning effect on the first bending section, and on the other hand, can limit the first bending section to avoid shaking, thereby improving the accuracy and stability of the connection between the tube sheet and the first side end screw.

[0021] In an optional embodiment of the above-mentioned heat exchanger, the second side end is provided with a fixing hole; the second fixed end is provided with a step portion, and the step portion includes a first step plate, a second step plate and a third step plate that are bent and connected in sequence; the first step plate is fixedly connected to the anti-collision strip, the second step plate abuts against the side of the heat exchange body facing the anti-collision strip, the third step plate abuts against the second side end and is provided with a mounting hole, and the mounting hole is connected to the fixing hole through a connecting piece.

[0022] The first step plate can form support for the anti-collision strip, forming a gap between it and the heat exchange main body. The cooperation between the second step plate and the third step plate and the heat exchange main body can achieve stable cooperation between the anti-collision strip and the heat exchanger, thereby improving the stability of the connection between the two.

[0023] In a third aspect, the present invention provides a mobile air conditioner, comprising: a compressor; and, as described above, a heat exchanger, wherein the first tube group is arranged toward the compressor.

[0024] When adopting the above technical solution, the heat exchanger anti-collision member is installed on the side of the heat exchanger facing the compressor, and the arc-shaped recess is arranged toward the first tube group. By recessing the second side of the anti-collision strip toward the first side to form the arc-shaped recess, when the compressor tilts toward the heat exchanger and hits the anti-collision strip, the arc-shaped recess will contact the heat exchanger. In this way, the width of the anti-collision strip can be reduced while the arc-shaped surface contacts the heat exchanger fins. This not only effectively disperses and absorbs the impact force, but also avoids cutting or severing the heat exchange fins / heat exchange tubes of the heat exchanger, thereby improving the safety of the heat exchanger.

[0040] The preferred embodiments of the present application are described below with reference to the accompanying drawings.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0043] Combine Figures 1 to 6As shown, the present invention provides a heat exchanger anti-collision member, including an anti-collision strip 40. The anti-collision strip 40 includes a first side surface 410 and a second side surface 420. The anti-collision strip 40 is recessed from the first side surface 410 to the second side surface 420 to form an arc-shaped recessed portion 430. The arc-shaped recessed portion 430 is configured so that the convex surface faces the heat exchanger 20 when the anti-collision strip 40 is mounted on the heat exchanger 20.

[0044] Optionally, the anti-collision strip 40 is used on the outdoor side of the air conditioner, where the heat exchanger 20 and compressor 30 are located. The anti-collision strip 40 is fixed to the side of the heat exchanger 20 facing the compressor 30. The first side 410 of the anti-collision strip 40 is recessed toward the second side 420 to form an arcuate recessed portion 430. Furthermore, when the arcuate recessed portion 430 is mounted on the heat exchanger 20, the arcuate convex surface faces the heat exchanger 20. This arcuate recessed portion 430 reduces damage to the heat exchange fins of the heat exchanger 20 when the compressor strikes the anti-collision strip 40, preventing scratches or damage to the fins.

[0045] Specifically, the air conditioner is a mobile air conditioner, a wall-mounted air conditioner, a floor-standing air conditioner, a window air conditioner, or the like.

[0046] The heat exchanger 20 is spaced apart from the compressor 30 and located on the air conditioner's floor. During operation, the compressor 30 vibrates violently, potentially causing it to topple. This can also happen during transportation due to improper handling. To prevent the compressor 30 from crushing the heat exchange fins or damaging the heat exchange tubes of the heat exchanger 20, a heat exchanger bumper is installed on the side of the heat exchanger 20 facing the compressor 30.

[0047] Optionally, the bumper strip 40 is configured as a rectangular strip. A curved recess 430 is formed on the rectangular bumper strip 40. This reduces the cross-sectional area of the bumper strip 40 while protecting the heat exchanger 20, thereby reducing the windshield area. This also reduces the material used in the bumper strip 40, thereby lowering costs, while maintaining its structural strength.

[0048] Alternatively, the anti-collision strip 40 may be configured in a cylindrical shape or a semi-cylindrical shape.

[0049] Optionally, the anti-collision strip 40 is extended along the length direction of the heat exchanger 20 .

[0050] Alternatively, the anti-collision strip 40 forms an angle with the length direction of the heat exchanger 20 .

[0051] When adopting the above technical solution, by recessing the second side surface of the anti-collision strip 40 toward the first side surface to form the arcuate recess 430, when the compressor 30 tilts toward the heat exchanger 20 and strikes the anti-collision strip 40, the arcuate recess 430 contacts the heat exchanger 20. This reduces the width of the anti-collision strip 40 while allowing the arcuate surface to contact the heat exchange fins of the heat exchanger 20. This not only effectively disperses and absorbs the impact force, but also prevents the heat exchange fins from being cut or severed, thereby improving the safety of the heat exchanger 20.

[0052] In an optional embodiment of the heat exchanger anti-collision member, the arc-shaped recessed portion 430 extends along the length direction of the anti-collision strip 40 .

[0053] By providing the arc-shaped recessed portion 430 extending along the length direction of the anti-collision strip 40, the impact force on the anti-collision strip 40 can be more effectively dispersed along the length direction of the arc-shaped recessed portion 430, thereby reducing local stress concentration and thus reducing direct damage to the heat exchanger.

[0054] Optionally, the arcuate recess 430 extends along the length of the bumper strip 40, forming a single, integral arcuate recess 430. Wings are formed on either side of the arcuate recess 430. When the compressor 30 falls, it contacts the bumper strip 40 and pushes against the wings. The wings can absorb some of the pressure and may bend to relieve it.

[0055] Alternatively, a plurality of arc-shaped recessed portions 430 are provided at intervals along the length direction of the anti-collision strip 40 .

[0056] In an optional embodiment of the heat exchanger anti-collision member, the heat exchanger anti-collision member further includes a flexible buffer member disposed on the first side surface 410 .

[0057] By providing the flexible buffer, when the compressor 30 tilts and impacts the anti-collision strip 40 , the impact of the compressor 30 can be buffered, thereby preventing the anti-collision strip 40 from being deformed or damaged.

[0058] Specifically, when the compressor 30 tilts toward the heat exchanger, it first contacts the heat exchanger's anti-collision member before contacting the heat exchanger, preventing the compressor 30 from directly impacting the heat exchanger. When the compressor 30 contacts the heat exchanger's anti-collision member, it first contacts the flexible buffer, which cushions the impact force of the compressor 30 and prevents deformation or damage to the compressor 30 or the anti-collision strip 40 caused by a rigid collision between the compressor 30 and the heat exchanger's anti-collision member.

[0059] Alternatively, the flexible buffer may not be provided.

[0060] In an optional embodiment of the above-mentioned heat exchanger anti-collision member, the arc-shaped recessed portion 430 has an arc-shaped groove 431, and the flexible buffer is arranged in the arc-shaped groove and at least partially extends out of the arc-shaped groove; and / or, the flexible buffer is arranged circumferentially around the arc-shaped groove.

[0061] Such an arrangement can improve the safety of the anti-collision strip 40 and prevent deformation or damage when it is hit by the compressor 30.

[0062] Specifically, the arcuate recess 430 faces the heat exchanger, and the opening of the arcuate groove 431 faces the compressor 30. Thus, a flexible buffer can be disposed within the arcuate groove 431 and / or disposed on the first side 410 circumferentially around the arcuate groove 431. When the flexible buffer is disposed within the arcuate groove 431, at least a portion of the flexible buffer extends out of the arcuate groove 431, thereby enhancing the buffering effect on the impact force of the compressor 30.

[0063] Optionally, the flexible buffer is fixed by gluing, screw connection, clamping, etc.

[0064] In an optional embodiment of the heat exchanger anti-collision member, the flexible buffer member includes one or more of a sponge member, an elastic rubber member or an elastic plastic member.

[0065] Sponge, with its excellent deformation and resilience, is particularly suitable for use as a cushioning material. Sponge also has a low density and is lightweight, requiring minimal load-bearing capacity. Elastic rubber components, with their excellent wear and heat resistance, are also suitable for use as flexible cushioning components. Elastic plastic components, with their excellent elastic deformation capabilities and wear resistance, also offer superior performance.

[0066] Combine Figures 3 to 6 as well as Figure 8 、 Figure 9 As shown, the present invention provides a heat exchanger 20 comprising a heat exchange body 200 and the aforementioned heat exchanger anti-collision member. The heat exchange body 200 includes at least a first tube group 240, which comprises a plurality of heat exchange tubes 201 arranged vertically and spaced apart. The heat exchanger anti-collision member is fixed to the heat exchange body 200, with the convex surface of the arcuate recess 430 facing the first tube group 240 and located between two adjacent heat exchange tubes 201.

[0067] By making the second side surface 420 of the anti-collision strip 40 concave toward the first side surface to form an arc-shaped recessed portion 430, and arranging the convex surface of the arc-shaped recessed portion 430 between two adjacent heat exchange tubes 201, when the compressor 30 tilts toward the first tube group 240 and hits the anti-collision strip 40, the arc-shaped recessed portion 430 can be squeezed and stuck between the two heat exchange tubes 201. The setting of the arc-shaped surface can avoid cutting or breaking the heat exchange tubes.

[0068] Specifically, the heat exchange main body 200 includes a first tube group 240, or includes multiple groups of heat exchange tube groups arranged at intervals along its own width direction, and the multiple groups of heat exchange tube groups include the first tube group 240. Each group of heat exchange tube groups includes multiple heat exchange tubes 201 arranged at intervals along the vertical direction. The heat exchange fins of the heat exchanger 20 are sleeved on the outer periphery of the multiple heat exchange tubes 201. Among them, the arc-shaped convex surface of the arc-shaped recessed portion 430 is located between two adjacent heat exchange tubes 201 of the adjacent first tube groups 240. In this way, when the heat exchanger anti-collision component is hit by the compressor 30, the anti-collision strip 40 will first squeeze the heat exchange fins, and after the heat exchange fins are tilted, they will contact the heat exchange tubes 201. Since the convex surface of the arc-shaped recessed portion 430 is located between two adjacent heat exchange tubes 201 , the arc-shaped convex surface of the arc-shaped recessed portion 430 is in smooth contact with the heat exchange tubes 201 , which can avoid cutting or breaking the heat exchange tubes 201 , thereby improving the safety of the heat exchanger 20 .

[0069] Alternatively, the arc-shaped recessed portion 430 may be disposed directly opposite to the heat exchange tube 201 .

[0070] Optionally, the heat exchanger 20 may be a condenser or an evaporator.

[0071] In an alternative embodiment of the above heat exchanger, in combination with Figures 4 to 6 As shown, the heat exchange body 200 also includes a first side end 210 and a second side end 220 extending vertically and located at both ends of the first tube group 240; the anti-collision strip 40 also includes a first fixed end 441 and a second fixed end 442; the first fixed end 441 corresponds to a detachable connection with the first side end 210, and the second fixed end 442 is detachably connected to the second side end 220.

[0072] By making the first fixed end 441 detachably connected to the first side end 210 and making the second fixed end 442 detachably connected to the second side end 220 , the flexibility of installing or removing the heat exchanger anti-collision component can be improved.

[0073] The detachable connection mentioned here includes connection methods such as snap connection, screw connection, riveting, and gluing.

[0074] In an optional embodiment of the above-mentioned heat exchanger, the first side end 210 is fastened and connected to the tube sheet 230, the tube sheet 230 is provided with a receiving groove 231, and the first fixed end 441 is provided with a first bent section 4411 bent toward the heat exchange main body 200, the first bent section 4411 is inserted into the receiving groove 231 and is screwed to the tube sheet 230.

[0075] The accommodating groove 231 provided on the tube plate 230 can, on the one hand, play a positioning effect on the first bending section 4411, and on the other hand, can limit the first bending section 4411 to avoid shaking, thereby improving the accuracy and stability of the screw connection between the tube plate 230 and the first side end 210.

[0076] Optionally, the first fixed end 441 of the anti-collision strip is bent toward the heat exchanger 20 to form a first bent section 4411. The provision of the first bent section 4411 facilitates the installation of the first fixed end 441.

[0077] Among them, the first side end 210 of the heat exchange main body 200 is provided with a tube sheet 230. The tube sheet 230 is covered on the first side end 210 to form a seal for the first side end 210 of the heat exchange main body 200. Furthermore, a receiving groove 231 is provided on the side of the tube sheet 230 facing the compressor 30. During installation, the first bent section 4411 can be inserted into the receiving groove 231 to achieve the positioning of the first fixed end 441. Furthermore, a first through hole 2311 is provided on the bottom wall of the receiving groove 231, and a second through hole 4412 matching the first through hole 2311 is provided on the first bent section 4411. Screws can be inserted into the first through hole 2311 and the second through hole 4412 to achieve a fixed connection between the first bent section 4411 and the tube sheet 230.

[0078] Optionally, the shape and size of the accommodating groove 231 match the shape and size of the first bending section 4411 .

[0079] Optionally, the accommodating groove 231 has an opening toward the heat exchanger 20 and an opening toward the compressor 30. Alternatively, the accommodating groove 231 has an opening away from the heat exchanger 20 and an opening toward the compressor 30.

[0080] Alternatively, the receiving groove 231 has only an opening toward the compressor 30 to form a slot.

[0081] Alternatively, the tube plate 230 is not provided with the accommodating groove 231 .

[0082] In an optional embodiment of the above-mentioned heat exchanger, the second side end 220 is provided with a fixing hole 221; the second fixed end 442 is provided with a step portion 443, and the step portion 443 includes a first step plate 4431, a second step plate 4432 and a third step plate 4433 which are bent and connected in sequence; the first step plate 4431 is fixedly connected to the anti-collision strip 40, the second step plate 4432 abuts against the side of the heat exchange body 200 facing the anti-collision strip 40, the third step plate 4433 abuts against the second side end 220, and is provided with a mounting hole 4434, and the mounting hole 4434 is connected to the fixing hole 221 through a connecting piece.

[0083] The first step plate 4431 can form support for the anti-collision strip 40, thereby forming a gap between it and the heat exchanger 20. The cooperation between the second step plate 4432 and the third step plate 4433 and the heat exchanger 20 can achieve stable cooperation between the anti-collision strip 40 and the heat exchange body 200, thereby improving the stability of the connection between the two.

[0084] Optionally, the first step plate 4431 is supported between the heat exchanger body 200 and the anti-collision strip 40 to accommodate the arc-shaped recessed portion 430 therebetween. Simultaneously, the second step plate 4432 abuts the side of the heat exchanger 20 facing the anti-collision strip 40, and the third step plate 4433 abuts the second side end 220, thereby improving the stability of the connection between the anti-collision strip 40 and the heat exchanger body 200. Furthermore, the third step plate 4433 is provided with a mounting hole 4434, which is connected to the fixing hole 221 via a connector, such as a screw. This secures the step portion 443 to the heat exchanger body 200, and further secures the second fixed end 442 of the anti-collision strip 40 to the heat exchanger 20.

[0085] Combine Figures 7 to 9 As shown, the present invention provides a mobile air conditioner, comprising: a heat exchanger 20 and a compressor 30 arranged at intervals; and, as the aforementioned heat exchanger anti-collision member, an anti-collision strip 40 is provided on the side of the heat exchanger 20 facing the compressor 30 .

[0086] Optionally, the mobile air conditioner further comprises a shell 10, the interior of which is a cavity. A middle partition 13 is provided inside the cavity, which divides the cavity into an indoor heat exchange chamber 11 and an outdoor heat exchange chamber 12 arranged one above the other. The heat exchanger 20, the compressor 30 and the outdoor fan are arranged in the outdoor heat exchange chamber 12. The shell 10 is provided with an air inlet and an air outlet corresponding to the outdoor heat exchange chamber 12. The heat exchanger 20, the compressor 30 and the outdoor fan are arranged in sequence between the air flow inlet and the air flow outlet along the air flow path. When the mobile air conditioner is started, the compressor 30 runs, and driven by the outdoor fan, air enters the outdoor heat exchange chamber 12 through the air flow inlet, flows through the compressor 30 and the heat exchanger 20 in sequence, and then flows out through the air flow outlet, thereby achieving cooling of the compressor 30 and the heat exchanger 20.

[0087] Optionally, a heat exchanger anti-collision member is provided on the side of the heat exchanger 20 facing the compressor 30 to prevent the compressor 30 from tilting during operation or transportation, thereby preventing damage or crushing to the heat exchanger 20.

[0088] When employing the above technical solution, by recessing the second side surface of the anti-collision strip 40 toward the first side surface 410 to form the arcuate recess 430, when the compressor 30 tilts toward the heat exchanger and strikes the anti-collision strip 40, the arcuate convex surface of the arcuate recess 430 contacts the heat exchanger 20. This reduces the width of the anti-collision strip 40 while allowing the arcuate convex surface to contact the heat exchange fins of the heat exchanger 20. This effectively disperses and absorbs the impact force while preventing damage to or severing of the heat exchange fins or heat exchange tubes, thereby improving the safety of the heat exchanger 20.

[0089] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
