[0072] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the principles of this application and are not intended to limit the scope of protection of this application. In the various drawings of this application, features with the same structure or similar function are represented by the same reference numerals.

[0073] like Figures 1-5As shown, the refrigeration appliance according to embodiments of the present application comprises a heat exchanger 1 arranged within a mechanical chamber, a housing 10 for holding the heat exchanger 1 and at least two electrically powered components. Here, the heat exchanger 1 can be particularly a micro-channel heat exchanger. The at least two electrically powered components can particularly include a fan 2 and a compressor 3. Among them, the housing 10 can be arranged outside the heat exchanger 1, and the heat exchanger 10 is connected to the housing 10 to be held. A first wire harness 20 from the fan 2 can be a weak current wire harness, and a second wire harness 30 from the compressor 3 can be a strong current wire harness.

[0074] In the prior art, the fan wire harness usually extends upward from the fan, does not pass through the housing, but is directly connected to the control unit (such as the power control board) through the foamed partition wire slot. The fan wire harness is in a free state without fixation. In addition, the compressor inverter wire harness is also directly connected to the power control board through the foamed partition wire slot above the compressor, also in a free state without fixation. In this way, on the one hand, since the weak current wire harness of the fan and the strong current wire harness of the compressor pass through the same wire slot, there are risks of being bumped, squeezed, electromagnetic interference, etc. between the two; on the other hand, since the internal space of the mechanical chamber is limited, each wire harness can be collided or squeezed by other components.

[0075] In addition to the fan and the compressor, the refrigeration appliance can also have at least one other electrically powered component in its mechanical chamber. Similarly, in the prior art, the wire harnesses from these other electrically powered components are also not effectively held. This further increases the degree of disordered distribution of the wire harnesses in the existing mechanical chamber.

[0076] According to embodiments of the present application, as shown, Figures 1-3 The housing 10 can have at least two wire harness containing structures 110, 120, which are arranged to allow the at least two wire harnesses 20, 30 from the at least two electrically powered components to pass through respectively so that the at least two wire harnesses 20, 30 are held apart from each other at least at the heat exchanger 1.

[0077] By arranging a corresponding wire harness containing structure for each wire harness to enable the wire harnesses to be held apart from each other at least at the heat exchanger 1, unnecessary interactions between the at least two wire harnesses 20, 30 and between them and other components, particularly, for example, the heat exchange fins 103 shown in Figure 2 and Figure 3 such as electromagnetic interference, collision and squeezing, etc. can be effectively avoided.

[0078] It is to be noted that although the embodiments of the present application are described in the context of at least two electric components being the fan 2 and the compressor 3 and the first and second wire harnesses being the weak and strong wire harnesses, respectively, the present application is not limited thereto. Under the technical concept of the present application, the refrigeration appliance allows having at least one other electric component in addition to the fan and the compressor in its mechanical chamber, and the other electric component can have a strong or weak wire harness, so that the wire harnesses respectively corresponding to the at least two wire harness accommodating structures of the housing 10 can be selected from any combination of the fan, the compressor and the other electric component and / or any combination of the strong and weak wire harnesses, respectively.

[0079] Therefore, in some embodiments, the at least two wire harnesses 20, 30 respectively corresponding to the at least two wire harness accommodating structures 110, 120 of the housing 10 of the heat exchanger 1 can comprise a first wire harness 20 and a second wire harness 30, wherein the first wire harness 20 can be a weak wire harness and the second wire harness 30 can be a strong wire harness. Additionally or alternatively, the at least two electric components can comprise the fan 2 and the compressor 3, in which case the first wire harness 20 of the fan 2 is a weak wire harness and the second wire harness 30 of the compressor 3 is a strong wire harness.

[0080] Preferably, in the connected state, the first wire harness 20 and the second wire harness 30 are always spaced apart from each other over the entire extension, so as to avoid mutual collision or mutual electromagnetic interference of both over the entire extension.

[0081] The housing 10 can have a frame structure, such as the illustrated rectangular frame, allowing the heat exchanger 1 to pass therethrough and be connected thereto. In some embodiments, the housing 10 is formed as a single frame structure, but in other embodiments, the housing 10 can comprise a heat exchanger holding portion 101 for holding the heat exchanger 1 and a fan holding portion 102 for holding the fan 2, wherein the heat exchanger holding portion 101 and the fan holding portion 102 are arranged substantially in parallel to allow the wind to flow through the heat exchanger 1 towards the compressor 3 by means of the fan 2. Here, the heat exchanger holding portion 101 and the fan holding portion 102 can each be formed as a rectangular frame, the two rectangular frames being preferably arranged substantially coaxially. Further, in some alternative embodiments, as illustrated in Figure 1 and Figure 2 the heat exchanger holding portion 101 and the fan holding portion 102 can be integrally formed.

[0082] The housing 10 can divide the mechanical chamber into two spaces, namely an air intake area and an air outlet area depending on the air supply direction of the heat exchanger 1, wherein the fan 2 and the compressor 3 are each arranged in the air outlet area on one side of the housing 10 (such as the right side area of the housing 10 in Figure 2 , while the control unit 5 is arranged in the air intake area on the other side of the housing 10 (such as the left side area of the housing 10 in Figure 2In the left side region of the housing 10. Therefore, under the action of the fan, the air from the air intake area can (in Figure 2 The airflow (from left to right) passes through heat exchanger 1 and flows to compressor 3. Fan 2 can be positioned in the airflow path, meaning heat exchanger 1, fan 2, and compressor 3 can be arranged sequentially in a roughly straight line. For example, as... Figure 2 As shown, the housing 10 and the compressor 3 can be arranged at approximately the same height relative to the machine room, as indicated by the dotted line in the figure, so that the heat exchanger 1, the fan 2 and the compressor 3 are arranged in approximately a straight line.

[0083] In some embodiments, the wire harness receiving structures 110, 120 of the housing 10 may be formed as through structures extending through the thickness dimension of the housing 10, thereby allowing the wire harnesses 20, 30, while accommodated in the wire harness receiving structures 110, 120, to be positioned relative to the thickness direction of the housing 10 (in the thickness dimension). Figure 1 The part marked X extends from one side of the housing 10 to the other. That is, as shown in the image. Figure 2 As shown, fan 2 and compressor 3 are arranged on the air outlet side of housing 10, and first wiring harness 20 and second wiring harness 30 extend from the air outlet side to the air inlet side, and can be connected to control unit 5 in the air inlet area via ports. Figure 2 In the diagram, control unit 5 is shown only schematically.

[0084] Since components such as the fan and compressor are located on opposite sides of the heat exchanger, far apart, and the wiring harness is long, it is particularly advantageous and effective to implement a wiring harness housing structure in the middle to support the wiring harness by means of a housing for holding the heat exchanger.

[0085] To achieve retention of the wire harness, in some embodiments, the wire harness receiving structures 110, 120 may have openings 111, 121 and receiving cavities 112, 122, with the openings 111, 121 opening in a direction transverse to the extending direction of the wire harness receiving structures 110, 120, thereby allowing the wire harnesses 20, 30 to enter the receiving cavities 112, 122 through the openings 111, 121 and be retained in the vertical direction to be held against gravity.

[0086] In such Figure 2 In the illustrated embodiment, the wire harness receiving structures 110 and 120 are arranged in the side 1011 of the housing 10, and the opening directions of the openings 111 and 121 form a certain angle with the extending direction of the side 1011 of the housing 10. However, this is not a limitation. In some embodiments, the wire harness receiving structures 110 and 120 may be arranged on the top edge of the housing 10, in which case the opening may be vertically upward or obliquely upward.

[0087] Preferably, the wire harness accommodating structure 110, 120 is configured to form a meandering path from the opening 111, 121 to the accommodating cavity 112, 122 inside. Such a meandering path can retain the wire harness in the accommodating cavity by the structural features of the wire harness accommodating structure 110, 120 itself without the need for other additional components to assist. Further preferably, the opening 111, 121 is located above the accommodating cavity 112, 122. In this way, the accommodating cavity can be utilized with a sink relative to the opening such that the wire harness is retained in the accommodating cavity once entered therein without easily exiting from the opening.

[0088] Preferably, the wire harness accommodating structure 110, 120 has a side wall section 113, 123 for defining the accommodating cavity 112, 122, the side wall section extending in a vertical direction. With the side wall section and the portion of the wire harness accommodating structure arranged opposite thereto, the accommodating cavity and the opening can be conveniently formed simultaneously.

[0089] In some embodiments, the wire harness accommodating structure 110, 120 can also have a curved guide portion 114, 124 located between the opening 111, 121 and the accommodating cavity 112, 122 to function as a transition. Preferably, the curved guide portion 114, 124 can have an arc-shaped profile to facilitate guiding the movement of the wire harness. Additionally or alternatively, in embodiments of the wire harness accommodating structure 110, 120 having a side wall section 113, 123 as shown, the curved guide portion 114, 124 and the side wall section 113, 123 are arranged opposite to each other and the shortest distance therebetween is greater than the diameter of the wire harness to define the opening 111, 121 to allow the wire harness to enter the accommodating cavity 112, 122 located inside the side wall section 113, 123. Figure 2

[0090] Preferably, the edges of the wire harness accommodating structure 110, 120 are chamfered. In this way, the wire harness can be prevented from being scratched when being accommodated into the wire harness accommodating structure.

[0091] Preferably, each wire harness accommodating structure 110, 120 has the same structure. Thereby, the housing 10 can be enabled to provide a plurality of versatile wire harness accommodating structures.

[0092] Preferably, the housing 10 can be made by an extrusion casting process. In particular, the housing 10 can be a one-piece structure.

[0093] ​In some embodiments, the wire harness accommodating structures 110, 120 can be arranged on the side of the housing 10. Generally, the mechanical chamber interior space above the fan 2 and the heat exchanger 1 is limited, and thus such a design can guide the wire harness to pass by the side of the heat exchanger 1 from the housing 10, without the need to route the wire harness above the heat exchanger 1, thereby facilitating the wiring. In this case, the openings 111, 121 can be open towards the lateral exterior of the housing 10, thereby facilitating the wire harness 20, 30 to enter the accommodating cavities 112, 122 from the side of the housing 10 via the openings 111, 121. Further, the openings 111, 121 can be open towards the lateral exterior of the housing 10 in a horizontal direction.

[0094] Preferably, the at least two wire harness accommodating structures 110, 120 are arranged on the same side 1011 of the housing 10. Additionally or alternatively, the at least two wire harness accommodating structures 110, 120 can be spaced apart from each other in the height direction of the housing 10. Additionally or alternatively, the at least two wire harness accommodating structures 110, 120 are arranged on the side of the housing 10 adjacent to the inlet and outlet pipes 1012, 1013 of the heat exchanger. These features are all conducive to providing a compact and clear wiring structure.

[0095] In some embodiments, the housing 10 can further have a wire protection portion 130, 140 extending further outwardly (i.e. in the X direction as shown in the drawings) from the wire harness accommodating structures 110, 120 along the through direction of the wire harness accommodating structures 110, 120. With the wire protection portion 130, 140, the wire harness 20, 30 can be protected from contacting or interfering with components such as the heat dissipation fins 103 of the heat exchanger 1. Figure 5

[0096] Preferably, as shown in the drawings, the longitudinal cross section of the wire protection portion 130, 140 is identical to the longitudinal cross section shape of the accommodating cavities 112, 122. Additionally or alternatively, the longitudinal cross section of the wire protection portion 130, 140 is substantially U-shaped. Figure 5

[0097] In some embodiments, the housing 10 can further have a pipe accommodating structure 150 arranged for accommodating the first pipe 40 of the heat exchanger 1, the pipe accommodating structure 150 being spaced apart from the wire harness accommodating structures 110, 120. Here, the first pipe 40 can be, for example, an outlet connecting pipe of the heat exchanger 1, one end of which is connected to the outlet pipe 1012 of the heat exchanger, extends through the pipe accommodating structure 150, and the other end of which is connected to a heat exchange pipe (not shown). Since the first pipe 40 of the heat exchanger 1 is arranged at a relatively low position, in the height direction of the housing 10, the pipe accommodating structure 150 is preferably arranged below the wire harness accommodating structures 110, 120.

[0098] ​​Preferably, the pipe accommodating structure 150 can be arranged on the same side 1011 of the housing 10 as the wire harness accommodating structures 110, 120. Preferably, the pipe accommodating structure 150 has the same structure as the wire harness accommodating structures 110, 120.

[0099] In some embodiments, the housing 10 can further comprise a protection structure 160 arranged to cover at least the openings 111, 121 of the wire harness accommodating structures 110, 120. Preferably, the protection structure 160 is arranged to cover at least the two wire harness accommodating structures 110, 120 and the pipe accommodating structure 150. Here, the protection structure 160 can be formed of a soft material such as foam. Thereby, the wire harness, and optionally the pipe, can be protected from unnecessary collision damage from other rigid structures and a seal is provided.

[0100] The first wire harness interface 201 of the fan 2 and the second wire harness interface 301 of the compressor 3 are arranged on the same side of the mechanical chamber of the refrigeration appliance as the wire harness accommodating structures 110, 120 of the heat exchanger 1. This can allow the first wire harness 20 and the second wire harness 30 to extend from the same side of the heat exchanger 1 through the housing 10 and be connected to the control unit 5, facilitating wiring, shortening the required wire harness length and facilitating that the first wire harness 20 and the second wire harness 30 are spaced apart from each other throughout the entire extension.

[0101] Additionally or alternatively, in some embodiments, the second wire harness 30 of the compressor 3 is accommodated in the wire harness accommodating structure 110, 120 of the at least two wire harness accommodating structures 110, 120 that is located at a lower position compared to the first wire harness 20 of the fan 2. As Figure 2 shown, the first wire harness 20 is accommodated in the first wire harness accommodating structure 110 located above and the second wire harness 30 is accommodated in the second wire harness accommodating structure 120 located below. The reason for this design is that typically the second wire harness interface 301 of the compressor 3 is lower in the height direction of the mechanical chamber than the first wire harness interface 201 of the fan 2.

[0102] Further, in the height direction of the mechanical chamber, the (second) wire harness accommodating structure 120 accommodating the second wire harness 30 of the compressor 3 can be lower than the first wire harness interface 201 of the fan 2 and higher than the second wire harness interface 301 of the compressor 3. Thereby, the wiring can be further optimized.

[0103] In some embodiments, the second wire harness 30 of the compressor 3 extends through a gap formed between the second pipe 41 (e.g. the inlet connection pipe) of the heat exchanger 1 and the fan 2. Thereby, a space-saving arrangement can be achieved.

[0104] By means of the wire harness accommodating structure and the pipeline accommodating structure provided on the shell, the wire harness and the pipeline are kept separate from each other, thereby making the wire harness layout in the mechanical chamber of the refrigeration appliance regular, preventing unnecessary electromagnetic interference or collision and extrusion of the wire harness.
