The heat pump system of a heating machine usually has multiple components, and the housing of the heating machine is provided with an installation cavity. The multiple components of the heat pump system are usually installed in the installation cavity using different brackets or fixing clips.

[0003] In the related art, the heat exchanger of the heat pump system is usually fixed on the mounting frame by a fixing clip, so as to facilitate the later maintenance or replacement of the heat exchanger. However, in order to fasten the heat exchanger on the mounting frame, it is usually necessary to press the fixing clip against the outer surface of the heat exchanger. When repairing or replacing the heat exchanger, it is necessary to first remove the screws of the fixing clip, then straighten the fixing clip, and finally remove the heat exchanger from the mounting frame. After replacing the new heat exchanger, it is necessary to restore the fixing clip and finally tighten the screws. The number of fixing clips is usually more than two, which makes the installation and removal of the heat exchanger more complicated, resulting in low efficiency in the later maintenance or replacement of the heat exchanger.

Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by this application.

[0027] In this application, unless otherwise clearly specified and defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0028] In addition, in this application, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0029] This application provides a casing, which is applied to a heating machine and provides an installation space for various components of the heating machine. Please refer to Figures 1 to 5 , in the embodiment of this application, the casing includes an outer shell and a mounting bracket 20. An installation cavity is provided inside the outer shell. The outer shell is usually formed by splicing multiple plate bodies. Among them, Figure 1 The fan, fan bracket of the heating machine and some plate bodies of the outer shell are omitted for easy display, that is, the fan, fan bracket and some face frame structures are not shown in the drawings. The installation cavity is mainly used to install the heat pump system of the heating machine. Usually, a fan cavity is also provided inside the outer shell, and the fan cavity is used to install the fan of the heating machine.

[0030] One side of the mounting bracket 20 is movably matched with the peripheral wall of the installation cavity, and the other side of the mounting bracket 20 is detachably and fixedly connected to the bottom wall of the installation cavity to fixedly arrange the mounting bracket 20 in the installation cavity. The mounting bracket 20 is provided with a mounting surface 2121 for mounting and fixing the heat exchanger 30.

[0031] That one side of the mounting bracket 20 is movably engaged with the peripheral wall of the mounting cavity means that a preliminary connection relationship is established between the mounting bracket 20 and the peripheral wall of the mounting cavity. For example, for insertion connection, when the other side of the mounting bracket 20 has not established a connection relationship with the bottom wall of the mounting cavity, the mounting bracket 20 can move relative to the peripheral wall of the mounting cavity, and the one side of the mounting bracket 20 can be movably engaged with or movably separated from the peripheral wall of the mounting cavity without the aid of tools.

[0032] It can be understood that after one side of the mounting bracket 20 is movably engaged with the peripheral wall of the mounting cavity, the other side of the mounting bracket 20 is detachably and fixedly connected to the bottom wall of the mounting cavity. Since the connection relationship between the mounting bracket 20 and the bottom wall of the mounting cavity is relatively fixed, the other side of the mounting bracket 20 will not be able to move relative to the peripheral wall of the mounting cavity, so that the mounting bracket 20 is fixedly installed in the mounting cavity; when the connection relationship between the mounting bracket 20 and the bottom wall of the mounting cavity is released, the mounting bracket 20 can move relative to the peripheral wall of the mounting cavity and can separate the mounting bracket 20 from the peripheral wall of the mounting cavity, so that the mounting bracket 20 can be detached from the mounting cavity.

[0033] It can be understood that the types of the heat exchanger 30 to be fixedly installed on the mounting surface 2121 include but are not limited to plate heat exchangers and shell-and-tube heat exchangers. Preferably, the mounting surface 2121 is for mounting and fixing a plate heat exchanger.

[0034] By the above technical solution of the present application, a mounting cavity is provided inside the housing, one side of the mounting bracket 20 is movably engaged with the peripheral wall of the mounting cavity, and the other side of the mounting bracket 20 is detachably and fixedly connected to the bottom wall of the mounting cavity to fixedly arrange the mounting bracket 20 in the mounting cavity. It can be seen that for the housing provided by the technical solution of the present application, the heat exchanger 30 is fixedly installed on the mounting surface 2121. By movably engaging one side of the mounting bracket 20 with the peripheral wall of the mounting cavity and detachably and fixedly connecting the other side of the mounting bracket 20 to the bottom wall of the mounting cavity, the heat exchanger 30 can be installed in the mounting cavity; by releasing the connection relationship between the mounting bracket 20 and the bottom wall of the mounting cavity and then driving the mounting bracket 20 to move relative to the peripheral wall of the mounting cavity, the heat exchanger 30 can be detached from the mounting cavity. In this way, the installation and disassembly of the heat exchanger 30 are relatively simple, and the efficiency of later maintenance or replacement of the heat exchanger 30 is improved.

[0035] In some examples, as Figures 1 to 4 shown, the housing includes a face frame and a reinforcing plate 10. An installation cavity is provided inside the face frame. The reinforcing plate 10 is fixedly arranged on the peripheral wall of the installation cavity. The reinforcing plate 10 is provided with a mating portion, and one side of the mounting bracket 20 is provided with a connecting portion. The connecting portion is movably engaged with the mating portion to be movably engaged with the peripheral wall of the mounting cavity through the reinforcing plate 10.

[0036] With such a setting, it is intended to enhance the overall structure of the housing through the reinforcing plate 10 to ensure the stability when the heat exchanger 30 is installed in the installation cavity.

[0037] In some examples, such as Figures 2 to 4 As shown, the reinforcing plate 10 is concavely provided with a card slot 11 in the vertical direction to form a mating portion, and one side of the mounting bracket 20 is convexly provided with a buckle 211 to form a connecting portion. The buckle 211 and the card slot 11 are movably engaged. With such a setting, it is intended to further facilitate the movable cooperation between the mounting bracket 20 and the peripheral wall of the installation cavity, so as to improve the efficiency of later maintenance or replacement of the heat exchanger 30.

[0038] In some examples, the reinforcing plate 10 is convexly provided with positioning columns in the horizontal direction to form a mating portion, and one side of the mounting bracket 20 is concavely provided with a card hole to form a connecting portion. The positioning columns and the card holes are movably inserted and engaged. With such a setting, it is intended to further facilitate the movable cooperation between the mounting bracket 20 and the peripheral wall of the installation cavity, so as to improve the efficiency of later maintenance or replacement of the heat exchanger 30.

[0039] In some examples, such as Figures 1 to 4 As shown, the mounting bracket 20 includes a mounting plate 21 and a support plate 22. The support plate 22 includes a support portion 221 extending in the vertical direction and an abutting portion 222. The support portion 221 is connected to the side of the mounting plate 21 away from the peripheral wall of the installation cavity, and the abutting portion 222 is connected to the side of the support portion 221 away from the mounting plate 21. The abutting portion 222 is detachably and fixedly connected to the bottom wall of the installation cavity, so that the mounting plate 21 is spaced from the bottom wall of the installation cavity. Among them, the mounting plate 21 is provided with a mounting surface 2121.

[0040] With such a setting, it is intended to space the mounting plate 21 from the bottom wall of the installation cavity through the support portion 221 of the support plate 22, so that the heat exchanger 30 can be suspended and installed on the mounting surface 2121 relative to the bottom wall of the installation cavity, so as to prevent the heat exchanger 30 from colliding with the bottom wall of the installation cavity due to external factors and affecting the stability of the heat exchanger 30.

[0041] In some examples, such as Figure 4 As shown, the abutting portion 222 is provided with an abutting surface parallel to the horizontal plane, and the abutting surface abuts against the bottom wall of the installation cavity. With such a setting, it is intended to increase the contact area between the abutting portion 222 and the bottom wall of the installation cavity through the abutting surface and improve the stability of the mounting bracket 20.

[0042] In some examples, such as Figure 4 and Figure 5As shown, two clamping plates 2222 are provided on the abutting surface of the abutting portion 222 in the vertical direction, and the two clamping plates 2222 are spaced apart to form a clamping groove 2223. A clamping piece that is inserted and matched with the clamping groove 2223 protrudes from the bottom wall of the installation cavity. Such a setting aims to improve the stability of the mounting bracket 20 installed in the installation cavity through the insertion and matching of the clamping piece and the clamping groove 2223.

[0043] Combined with the content that the reinforcing plate 10 is recessed with a clamping groove 11 in the vertical direction, the two sides of the clamping groove 2223 in the vertical direction are through, so as to facilitate the installation and disassembly of the mounting bracket 20.

[0044] Combined with the content that the reinforcing plate 10 protrudes with positioning columns in the horizontal direction, the two sides of the clamping groove 2223 in the length direction of the positioning column are through, so as to facilitate the installation and disassembly of the mounting bracket 20.

[0045] In some examples, as Figure 4 shown, through holes 2224 are provided through the two clamping plates 2222 and the clamping piece in the horizontal direction. Such a setting aims to enable the two clamping plates 2222 and the clamping piece to be fixedly connected by bolts, pins, etc.

[0046] It should be noted that in some examples, a threaded hole 2221 is provided on the abutting surface of the abutting portion 222, so that the abutting portion 222 can be fixedly connected to the bottom wall of the installation cavity through the threaded hole 2221.

[0047] In some examples, as Figure 4 and Figure 5 shown, the mounting plate 21 includes a mounting portion 212 and a reference portion 213. The reference portion 213 is provided with a reference surface 2131 parallel to the horizontal plane. The mounting portion 212 is connected to the first side edge 2132 of the reference surface 2131. The mounting portion 212 is provided with a mounting surface 2121. The supporting portion 221 is connected to the second side edge 2133 of the reference surface 2131 away from the installation cavity. Among them, the first side edge 2132 and the second side edge 2133 are adjacent to each other.

[0048] Such a setting aims to enhance the overall strength of the mounting bracket 20 and improve the stability when the heat exchanger 30 is installed on the mounting surface 2121. In addition, when installing the plate-type heat exchanger 21, the reference surface 2131 can be used as a reference for the horizontal plane to improve the installation accuracy of the heat exchanger 30.

[0049] In some examples, when the mounting surface 2121 is used to install a fixed-tube-sheet heat exchanger, the bottom of the tube-sheet heat exchanger can be placed on the reference surface 2131.
