[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0044] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0045] Reference Figure 1 and Figure 2 As shown, a shell assembly 1000 of an embodiment of the utility model can be used in an air handling unit 300. The shell assembly 1000 includes a shell 100, an insulation layer 400 and a positioning member 200. The shell 100 includes a frame 110, a side wall 120 and an upper cover 150. The side wall 120 is arranged around the outer side of the frame 110, and the upper cover 150 is connected to the upper end of the side wall 120. It should be noted that the shell 100 can be a split structure (i.e., composed of multiple detachable shells 100) or an integral structure (i.e., composed of one shell 100). For example, Figure 1 The embodiment shown in the figure is a split structure, and the housing 100 includes a fan box 130 and a heat exchange box 140. In the vertical arrangement assembly stage of this embodiment, the heat exchange box 140 is generally installed first, and then the fan box 130 is stacked on the top of the heat exchange box 140, and finally the heat exchange box 140 and the fan box 130 are fastened to complete the assembly. The split structure is adopted, and the housing 100 is easy to transport and assemble.

[0046] Reference Figure 4 As shown, the insulation layer 400 is connected to the inner side of the side wall 120 to prevent heat from being transferred to the outer side of the shell assembly 1000 through the side wall 120. It should be noted that the insulation layer 400 can be made of materials such as glass wool, rock wool, polyurethane, and foam rubber. The positioning member 200 is fixedly connected to the frame 110 and is located on the inner side of the side wall 120. The positioning member 200 is attached to the side of the insulation layer 400 away from the side wall 120, and the positioning member 200 is configured to be able to apply a force toward the side wall 120 to the insulation layer 400, so that the insulation layer 400 and the side wall 120 are attached, reducing the separation of the insulation layer 400 and the side wall 120. Multiple positioning members 200 can be provided to further improve the stability of limiting the insulation layer 400.

[0047] It is understandable that the above solution, by using the positioning member 200 to limit the position of the thermal insulation layer 400, does not require the use of glue, does not have the risk of glue aging, and reduces the use cost; at the same time, it can effectively reduce the risk of the thermal insulation layer 400 falling off, and improve the safety of use. The positioning member 200 makes the thermal insulation layer 400 fit with the side wall 120, which can reduce the situation of the thermal insulation layer 400 bulging and expanding, and improve the reliability and stability of the thermal insulation layer 400.

[0048] It should be noted that, as an alternative embodiment, the thermal insulation layer 400 can also be fixedly connected to the side wall 120 by glue, and then the thermal insulation layer 400 is limited by the positioning member 200. When the glue ages and fails, the risk of the thermal insulation layer 400 being drawn into the fan 310 can also be reduced by limiting the positioning member 200. The appropriate solution is selected according to the actual situation.

[0049] Reference Figure 3 and Figure 7 As shown, in the embodiment of the present invention, the positioning member 200 includes a protruding portion 210 and a fixing portion 220, and both ends of the protruding portion 210 are connected to the fixing portion 220. The fixing portion 220 is fixedly connected to the frame 110, for example, referring to Figure 2 As shown, the frame 110 includes a support rod 111 and a bent portion 112, and the two ends of the fixing portion 220 are respectively connected and fixed to the bent portion 112 and the support rod 111. The protruding portion 210 protrudes toward one side of the thermal insulation layer 400, thereby applying a force toward the side wall 120 to the thermal insulation layer 400, so that the thermal insulation layer 400 can be attached to the side wall 120, reducing the occurrence of knocking, bulging, etc. of the thermal insulation layer 400.

[0050] Reference Figure 7 As shown, in an embodiment of the utility model, the fixing portion 220 and the protruding portion 210 are integrally formed by metal wire. The fixing portion 220 includes an annular body 221, and the annular body 221 is fixedly connected to the frame 110 by screws. It is understandable that the metal wire can form the protruding portion 210 and the fixing portion 220 after a bending process, so the manufacturing method of the positioning member 200 is simple, convenient and low in cost. The annular body 221 is annular, which is convenient for screw fixing and improves assembly efficiency. As an alternative embodiment, the fixing portion 220 can also be a structure formed by punching after stamping to form a flat structure, or a structure formed by punching after bending, and a suitable solution can be selected according to actual conditions.

[0051] Reference Figure 2 and Figure 3 As shown, in the embodiment of the present invention, the protrusion 210 is configured as an arc-shaped protrusion or a step-shaped protrusion. It is understandable that the arc-shaped or step-shaped protrusion 210 needs to be designed according to the flatness of the side wall 120, for example Figure 7The protrusion 210 in the embodiment is an arc-shaped protrusion. Figure 2 As can be seen in the figure, the side wall 120 is relatively flat. The protrusion 210 has a certain elastic deformation, so the protrusion 210 is designed to be an arc-shaped protrusion, which is more convenient to manufacture and allows the protrusion 210 to produce a certain elastic deformation when it abuts against the insulation layer 400, thereby better compressing the insulation layer 400 and making the insulation layer 400 fit the side wall 120.

[0052] Reference Figure 2 As shown, when the inner side of the side wall 120 is protruded to form a protrusion 121, for example, two protrusions 121 are provided and are spaced apart. The protrusion will lift up the insulation layer 400, so it is necessary to design the protrusion 210 into a step-like structure, for example Figure 8 The protrusion 210 is a step-shaped protrusion to adapt to the shape of the protrusion 121, so that the insulation layer 400 and the side wall 120 fit together. Therefore, the protrusion 210 needs to be designed according to the specific structure of the side wall 120, so that the insulation layer 400 can better fit the side wall 120, and reduce the adverse effects of the insulation layer 400 such as warping and bulging. It should be noted that the positions of protrusions 210 of different shapes are only for illustration, and do not limit the arc-shaped protrusion 210 to be set at the bottom, and the step-shaped protrusion 210 must be set at the bottom, and the position can be determined according to actual conditions. The number of protrusions 210 can be one, two, three, etc., and the appropriate number is selected according to actual conditions.

[0053] Reference Figure 2 and Figure 3 As shown, in another embodiment of the utility model, the positioning member 200 includes a pressing plate 230, and the pressing plate 230 is connected to the frame 110 to fix the relative position between the pressing plate 230 and the shell 100. An interlayer space for accommodating the thermal insulation layer 400 is formed between the pressing plate 230 and the side wall 120, thereby limiting the position of the thermal insulation layer 400. It should be noted that the shell 100 includes a fan box 130 and a heat exchange box 140, and the fan box 130 is located above the heat exchange box 140. A heat exchanger 320 is arranged in the heat exchange box 140. Since the air flow needs to pass through the heat exchanger 320, the wind pressure in the heat exchange box 140 is relatively large. For this reason, a pressing plate 230 is arranged in the heat exchange box 140 to limit the position of the thermal insulation layer 400, which can more effectively limit the position of the thermal insulation layer 400, avoid the thermal insulation layer 400 from falling off under the influence of wind pressure, and improve the reliability of the thermal insulation layer 400. The fan box 130 is provided with a fan 310, and both sides of the fan 310 suck air from the heat exchange box 140 and blow air toward the upper end of the housing 100. Compared with the wind pressure of the heat exchange box 140, the wind pressure of the fan box 130 is smaller, so the metal wire-shaped positioning member 200 can be used to limit the position of the insulation layer 400, thereby reducing costs.

[0054] It should be noted that a portion of the plurality of positioning members 200 is a metal wire-shaped positioning member 200, and another portion is a pressing plate 230, for example Figure 3 As an alternative embodiment, the plurality of positioning members 200 may all be wire-shaped positioning members 200, or the plurality of positioning members 200 may all be pressing plates 230. Fig. 9 As shown, in another embodiment, the heat exchange box 140 can also be limited by a metal wire-like positioning piece 200. By increasing the number of metal wire-like positioning pieces 200, or by fixing the insulation layer 400 by gluing, and then limiting it by a metal wire-like positioning piece 200, the position of the insulation layer 400 can also be effectively limited, so that the insulation layer 400 and the side wall 120 fit together. The appropriate solution is selected according to the actual situation.

[0055] Reference Figure 5 As shown, in the embodiment of the utility model, the pressing plate 230 is provided with a weight-reducing hole 231, and the weight-reducing hole 231 is constructed as a plurality of through holes arranged in an array on the pressing plate 230. The number, size, shape, etc. of the through holes are designed according to actual conditions. Among them, the provision of the weight-reducing hole 231 has little effect on the degree of fitting of the thermal insulation layer 400, and at the same time, the weight-reducing hole 231 can also reduce the overall weight of the pressing plate 230, reduce the materials required for the pressing plate 230, reduce the production cost, and facilitate handling and installation, thereby improving production efficiency.

[0056] Reference Figure 1 and Figure 2 As shown, in an embodiment of the utility model, the housing 100 is annularly arranged around an axis, and the axis can be a line extending in the up-down direction. The side wall 120 includes a plurality of plates arranged around the axis, for example, the plurality of plates are respectively a first plate 122, a second plate 123, a third plate 124 and a fourth plate, and the first plate 122, the second plate 123, the third plate 124 and the fourth plate are arranged around the circumference of the housing 100 and are fixedly connected to the frame 110, thereby forming an installation space for installing the fan 310 and the heat exchanger 320. That is, the first plate 122 and the third plate 124 are arranged relative to each other, and the second plate 123 and the fourth plate are arranged relative to each other. Among them, the fourth plate can be a box door, and the box door and the first plate 122 and the third plate 124 are connected by means of magnetic attraction, snap-on or the like, so as to facilitate subsequent disassembly and assembly. The heat-insulating layer 400 includes a plurality of plate-shaped heat-insulating units 410 , and each heat-insulating unit 410 is respectively connected to a corresponding plate body, thereby playing a role of heat insulation.

[0057] Reference Figure 6As shown, in an embodiment of the utility model, the frame 110 includes a plurality of support rods 111 arranged at circumferential intervals along the axis, the plurality of support rods 111 include a first support rod 134 and a second support rod 144 located on both sides of one of the insulation units 410, the first support rod 134 is provided with a first folded edge 113, the second support rod 144 is provided with a second folded edge 114, the first folded edge 113 and the second folded edge 114 are respectively fitted with the edges of both sides of the insulation unit 410, thereby limiting the position of the edge of the insulation unit 410, effectively reducing the warping of the edge of the insulation unit 410, and improving the reliability of the insulation unit 410.

[0058] An air handling unit 300 of an embodiment of the utility model includes the shell assembly 1000 of the above embodiment. The air handling unit 300 can be a split structure or an integral structure. The air handling unit 300 is generally installed in an attic or a basement. Due to its complex installation environment and narrow installation space, a structure in which multiple module boxes are assembled is usually adopted. The air handling unit 300 of the embodiment of the utility model adopts the shell assembly 1000 of the above embodiment. The shell assembly 1000 is arranged by surrounding the outer side of the frame 110 with the side wall 120 of the shell 100, the insulation layer 400 is connected to the inner side of the side wall 120, the positioning member 200 is fixedly connected to the frame 110 and is located on the inner side of the shell 100, and the positioning member 200 and the insulation layer 400 are attached to the side away from the side wall 120, so that the insulation layer 400 can be attached to the side wall 120. By using the positioning member 200 to limit the position of the thermal insulation layer 400, the risk of the thermal insulation layer 400 falling off can be effectively reduced, and the safety of use can be improved. At the same time, the positioning member 200 is used to make the thermal insulation layer 400 fit the side wall 120, which can reduce the bulging of the thermal insulation layer 400 and improve the reliability and stability of the thermal insulation layer 400.

[0059] Since the air handling unit 300 of the embodiment of the utility model adopts all the technical solutions of the shell assembly 1000 of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0060] Reference Figure 1 and Figure 2As shown, in the embodiment of the utility model, the air handling unit 300 also includes a fan 310 and a partition 330, and the shell 100 includes a first shell 100, and the first shell 100 is a fan box 130, and the fan box 130 is used to accommodate the fan 310. The fan box 130 includes a first frame 131, a first side wall 132, an upper cover 150 and a lower frame 133, the first side wall 132 is connected to the first frame 131 in a surrounding manner, the upper cover 150 is connected to the upper end of the first side wall 132, and the lower frame 133 is connected to the lower end of the first side wall 132. The first side wall 132 includes a first plate body 122, a second plate body 123, a third plate body 124 and a fourth plate body, and the fourth plate body is in a hidden state in the figure. Refer to Figure 3 As shown, the first frame 131 includes two first support rods 134, the second plate 123 is connected between the two first support rods 134, the first plate 122 and the third plate 124 are respectively located on the left and right sides of the second plate 123, one side of the first plate 122 and the third plate 124 is respectively connected to a first support rod 134, and is arranged at an angle (generally a right angle) with the middle second plate 123, and the fourth plate is connected to the first plate 122 and the third plate 124, and is arranged opposite to the second plate 123. The partition 330 is connected to the first frame 131, and the fan 310 is installed on the partition 330. The insulation layer 400 arranged on the first side wall 132 is the first insulation layer 400. The positioning member 200 includes a protrusion 210, and the protrusion 210 is abutted and matched with the first insulation layer 400 arranged on the first shell 100, so that the first insulation layer 400 and the first shell 100 are fitted. The protrusion 210 , the partition 330 , the first side wall 132 and the first frame 131 jointly limit the first thermal insulation layer 400 of the first shell 100 , thereby reducing the risk of the first thermal insulation layer 400 loosening and falling off.

[0061] Reference Figure 2 and Figure 5As shown, in the embodiment of the utility model, two metal wire-shaped positioning members 200 can be respectively provided at the first plate body 122 and the third plate body 124, and only one metal wire-shaped positioning member 200 can be provided at the second plate body 123. Since the air inlets on both sides of the fan 310 are respectively arranged toward the first plate body 122 and the third plate body 124, the wind pressure on the first plate body 122 and the third plate body 124 is greatly affected when the fan 310 enters the air, so more positioning members 200 need to be provided to limit the first thermal insulation layer 400. That is, the first thermal insulation layer 400 provided on the first plate body 122 and the third plate body 124 is limited in position by the upper cover 150, the partition plate 330, the two metal wire-shaped positioning members 200 and the lower frame body 133 from top to bottom, so as to reduce the risk of the first thermal insulation layer 400 falling off. The second plate 123 and the fourth plate are less affected by wind pressure, so only one wire-shaped positioning member 200 can be provided, which is located in the first insulation layer 400 of the second plate 123 and the fourth plate, and is limited by the upper cover 150, the partition 330 and a wire-shaped positioning member 200 from top to bottom. Reducing the number of positioning members 200 can save costs. Of course, the above number is only an example, and the specific number can be selected according to actual conditions.

The second side wall 142 includes a fifth plate 145, a sixth plate 146, a seventh plate 147 and an eighth plate, and the eighth plate is in a hidden state in the figure. The second frame 141 includes two second support rods 144, the sixth plate 146 is connected between the two second support rods 144, one side of the fifth plate 145 and the seventh plate 147 is connected to a second support rod 144 respectively, and is arranged at an angle (generally a right angle) with the sixth plate 146 in the middle, and the eighth plate is connected to the fifth plate 145 and the seventh plate 147, and is arranged opposite to the sixth plate 146. The heat exchanger 320 is installed on two guide rails 340, and the heat exchanger 320 can be dragged out along the guide rails 340 when it needs to be repaired or cleaned. The insulation layer 400 connected to the second side wall 142 is the second insulation layer 400. The positioning member 200 includes a pressure plate 230 attached to the second side wall 142. The pressure plate 230, the guide rail 340, the second side wall 142 and the second frame 141 jointly limit the second insulation layer 400, thereby effectively limiting the position of the second insulation layer 400 and reducing the risk of the second insulation layer 400 loosening and falling off.

[0063] It is understandable that when the second insulation layer 400 adopts the solution of glass wool, part of the glass wool is prone to wrinkling and bulging. For this reason, the second frame 141 can limit the position of the side edge of the second insulation layer 400 by cooperating with the second side wall 142; the upper frame 143, the lower cover 160 and the guide rail 340 can limit the position of the upper edge and the lower edge of the second insulation layer 400 by cooperating with the second side wall 142; the pressure plate 230 is used to limit the position of the middle part of the second insulation layer 400. By adopting this solution, the wrinkling and bulging of the second insulation layer 400 can be effectively reduced, and the impact on the air intake of the fan 310 can be reduced. At the same time, it can effectively reduce the loosening and falling of the second insulation layer 400, and improve the reliability of the second insulation layer 400.

[0064] It should be noted that when the housing 100 is an integral housing, the first plate 122 and the fifth plate 145 are an integral body, the second plate 123 and the sixth plate 146 are an integral body, the third plate 124 and the seventh plate 147 are an integral body, and the fourth plate and the eighth plate are an integral body. Of course, it is also feasible that at least a part of the first plate 122 and the fifth plate 145, the second plate 123 and the sixth plate 146, the third plate 124 and the seventh plate 147, and the fourth plate and the eighth plate are two independent plates, and the appropriate form is selected according to the actual situation.

[0065] Reference Figure 1 , Figure 2 and Fig.10 As shown, in the embodiment of the utility model, the frame 110 also includes a bending portion 112, and the edges of the first plate body 122 and the third plate body 124 facing the fourth plate body are provided with a bending portion 112, and the edges of the fifth plate body 145 and the seventh plate body 147 facing the eighth plate body are also provided with a bending portion 112. For example, the bending portion 112 can be integrally formed with the side wall 120, or connected to the side wall 120 by welding, clamping, fastener connection, etc. The bending portion 112 is bent and a limiting groove is defined between the bending portion 112 and the side wall 120, and the limiting groove is not shown in the figure. The limiting groove cooperates with one side edge of the insulation layer 400, thereby limiting the position of the edge of the insulation layer 400. At the same time, a limiting groove is also formed between the support rod 111 and the side wall 120, so as to cooperate with the other side edge of the insulation layer 400, and can also limit the position of the edge of the insulation layer 400, effectively reducing the situation where the edge of the insulation layer 400 is knocked up.
