[0049] like Figures 1 to 4 As shown, Figure 1 The structure diagram of the condenser assembly 10 according to the embodiment of the utility model is schematically shown (the cover plate 12 is in the second state). Figure 2 for Figure 1 The condenser assembly 10 shown in FIG. 1 is a schematic structural diagram of a second viewing angle, Figure 3 for Figure 2 The partially enlarged structural diagram of the condenser assembly 10 at A shown in FIG. Figure 4 for Figure 1 The cover plate 12 of the condenser assembly 10 shown in the figure is in the first state. The first aspect of the utility model proposes a condenser assembly 10, which includes a condenser body 11 and a cover plate 12 rotatably connected to an end plate 112, at least one end of the condenser body 11 is provided with an end plate 112, and the end plate 112 is provided with a through hole 113; the cover plate 12 has a first state in which a water chamber is enclosed with the end plate 112 and a second state in which the water chamber is open, and the cover plate 12 can also switch between the first state and the second state, wherein the cover plate 12 is in the first state, and the through hole 113 is connected to the water chamber.

[0050] In the first state, the cover plate 12 is in a closed state, and in the second state, the cover plate 12 is in an open state. The number of the end plates 112 here can be one or two, wherein the two end plates 112 are respectively arranged at both ends of the condenser body 11 along the length direction, wherein the length direction of the condenser body 11 is the axial direction of the condenser body 11.

[0051] It should be noted that the end plate 112 and the cover plate 12 are sealed to reduce the probability of water leaking out of the water chamber. The specific sealing connection method can adopt a sealing ring structure or other sealing methods. In addition, the rotatable connection between the end plate 112 and the cover plate 12 mentioned here can be realized by adopting a hinge 13 structure or a rotating door hinge structure. The specific structure will be described in detail later.

[0052] According to the condenser assembly 10 of the utility model, a condenser body 11 and a cover plate 12 rotatably connected to an end plate 112 are provided, wherein the cover plate 12 has a first state in which a water chamber is enclosed with the end plate 112 and a second state in which the water chamber is opened, and can be switched between the first state and the second state. When cleaning the condenser body 11, it is only necessary to remove the cover plate 12 from the end plate 112 and switch it to the second state. The condenser body 11 can be cleaned without lifting out the cover plate 12, thereby reducing the difficulty.

[0053] Alternatively, if Figure 1 and Fig. 9 As shown, the condenser body 11 includes a shell 111 and a heat exchange tube 114, wherein the heat exchange tube 114 is arranged inside the shell 111, and part of the heat exchange tube 114 is arranged in the through hole 113, wherein the heat exchange tube 114 can be a tube body that plays a condensation role.

[0054] Alternatively, if Figures 1 to 4 As shown, the condenser assembly 10 includes a hinge 13, and the cover plate 12 can be connected to the end plate 112 through the hinge 13. Considering that the end plate 112 is very heavy, in order to reduce the probability of the cover plate 12 falling off the end plate 112, the hinge 13 is used in the utility model to achieve a rotatable connection between the end plate 112 and the cover plate 12.

[0055] The following will focus on the structure of the hinge 13. Figures 1 to 4 As shown, the hinge 13 includes a first connecting member 131, a second connecting member 132 and a connecting shaft 133; wherein, one end of the first connecting member 131 is fixedly connected to the end plate 112, and the other end of the first connecting member 131 is rotatably connected to the connecting shaft 133; one end of the second connecting member 132 is fixedly connected to the cover plate 12, and the other end of the second connecting member 132 is rotatably connected to the connecting shaft 133.

[0056] It should be noted that the fixed connection between one end of the first connecting member 131 and the end plate 112 can be achieved by welding or by integral forming. The first connecting member 131 can be made of metal, and the end plate 112 can also be made of metal. One end of the first connecting member 131 and the end plate 112 are fixed by welding, and can be fixed by fusion welding or brazing. In addition, a circular hole can be set at the other end of the first connecting member 131, and the connecting shaft 133 is inserted into the circular hole to achieve a rotatable connection between the connecting shaft 133 and the first connecting member 131.

[0057] Accordingly, the fixed connection between one end of the second connecting member 132 and the end plate 112 can be achieved by welding or by integral forming. The second connecting member 132 can be made of metal, and the end plate 112 can also be made of metal. One end of the second connecting member 132 and the end plate 112 are fixed by welding, and can be fixed by fusion welding or brazing. In addition, a circular hole can be set at the other end of the second connecting member 132, and the connecting shaft 133 is inserted into the circular hole to achieve a rotatable connection between the connecting shaft 133 and the second connecting member 132.

[0058] Here, the number of the first connecting member 131 , the second connecting member 132 and the connecting shaft 133 can all be one, so that the cover plate 12 and the end plate 112 are rotatably connected.

[0059] In order to better fix the cover plate 12, the number of the first connecting members 131 is two or more, and two adjacent first connecting members 131 are spaced apart along the axial direction of the connecting shaft 133; the number of the second connecting members 132 is also two or more, and two adjacent second connecting members 132 are spaced apart along the axial direction of the connecting shaft 133, and the axial direction of the connecting shaft 133 is parallel to the connecting shaft 133. Figure 5 The YY direction is the same.

[0060] The condenser assembly 10 in the utility model sets the number of the first connecting members 131 to be two or more, and also sets the number of the second connecting members 132 to be two or more, wherein two adjacent first connecting members 131 are spaced apart along the axial direction of the connecting shaft 133, and two adjacent second connecting members 132 are spaced apart along the axial direction of the connecting shaft 133, then the connection between the end plate 112 and the cover plate 12 can be achieved from at least two positions, so that the cover plate 12 can be stably connected to the end plate 112, thereby reducing the probability of the cover plate 12 falling off from the end plate 112.

[0061] Optionally, continue to refer to Figure 3 and Figure 4As shown, a groove 121 is formed on the surface of the cover plate 12 facing the end plate 112, and the groove 121 and the end plate 112 form a water chamber, that is, the groove 121 is a spherical groove structure, so that the cover plate 12 can be formed into a spherical structure with the groove 121, such as a hemispherical structure.

[0062] It can be understood that the interior of the groove 121 here is an arc-shaped structure, which can realize the function of storing water, so that the water chamber can accommodate water.

[0063] In addition, if Figures 1 to 4 As shown, the condenser assembly 10 also includes a connecting component 14. In order to ensure that the cover plate 12 can be stably fixed to the end plate 112 in the first state, optionally, a mounting portion 123 is formed on the circumferential edge of the groove 121. The mounting portion 123 here is a circular plate-like structure. A first mounting hole 1231 is provided on the mounting portion 123, and a second mounting hole 1121 arranged opposite to the first mounting hole 1231 is provided on the end plate 112. The connecting component 14 is sequentially passed through the first mounting hole 1231 and the second mounting hole 1121 to realize a detachable connection between the cover plate 12 and the end plate 112.

[0064] Here, there are multiple first mounting holes 1231, and the multiple first mounting holes 1231 are arranged at circumferential intervals along the mounting portion 123. Correspondingly, there are also multiple second mounting holes 1121, and the multiple second mounting holes 1121 are arranged in a circular ring structure, so that multiple connecting components 14 can connect the cover plate 12 and the end plate 112 from multiple positions, thereby realizing a detachable connection between the cover plate 12 and the end plate 112, and stably fixing the cover plate 12 at the same time.

[0065] like Figure 2 and Figure 3 As shown, optionally, a partition 122 is provided in the groove 121, and the partition 122 can separate the groove 121 into a first groove portion and a second groove portion, wherein a first water chamber 1211 is formed between the first groove portion and the end plate 112, and a second water chamber 1212 is formed between the second groove portion and the end plate 112, that is, the partition 122 separates the water chamber into a first water chamber 1211 and a second water chamber 1212; the number of through holes 113 is two or more, and two or more through holes 113 are respectively arranged toward the first water chamber 1211 and the second water chamber 1212, that is, a part of the through holes 113 is connected to the first water chamber 1211, and another part of the through holes 113 is connected to the second water chamber 1212, and the space in the groove 121 is divided into two parts, the first water chamber 1211 and the second water chamber 1212, by the partition 122.

[0066] It should be noted that the first water chamber 1211 and the second water chamber 1212 here are four-pass or two-pass structures, which can be selected and used according to the heat exchange effect.

[0067] The number of through holes 113 is multiple rows, and the direction of each row is XX direction. Figure 5 In the embodiment, the through holes 113 are arranged in zones on the partition 122, and there are five zones from top to bottom, wherein four rows of through holes 113 are arranged in the first zone, four rows of through holes 113 are arranged in the second zone, four rows of through holes 113 are arranged in the third zone, three rows of through holes 113 are arranged in the fourth zone, and four rows of through holes 113 are arranged in the fifth zone, wherein the first water chamber 1211 is located below the second water chamber 1212, so that the space in the groove 121 can be divided into two spaces to realize water storage. Of course, the first water chamber 1211 and the second water chamber 1212 can also be interchanged.

[0068] It should be noted that the partition 122 here can be a plate body arranged in a horizontal direction, such as an arc-shaped plate. The partition 122 here can also be arranged at an angle, and can also separate the space in the groove 121 into a first water chamber 1211 and a second water chamber 1212.

[0069] It should be noted that a first stop valve 30 connected to the first water chamber 1211 is installed on the cover plate 12 to facilitate the treatment of the gas in the first water chamber 1211, and a second stop valve 40 connected to the second water chamber 1212 is also installed on the cover plate 12 to facilitate the treatment of the water in the second water chamber 1212.

[0070] Optionally, a drainage hole 1213 is provided on the partition 122, wherein the drainage hole 1213 can introduce the water in the first water chamber 1211 into the second water chamber 1212 to discharge the water in the first water chamber 1211. The drainage hole 1213 here can be a circular hole, a rectangular hole or a structure of other shapes.

[0071] The second aspect of the present invention provides a chiller 100, such as Figures 5 to 8 As shown, Figure 5 The schematic diagram of a part of the structure of the chiller 100 according to the embodiment of the utility model is shown schematically (the inspection door 21 is in an open state). Figure 6 for Figure 5 The cross-sectional structure diagram of the chiller 100 along the cross section BB shown in FIG. Figure 7 for Figure 5 The structure diagram of the chiller 100 shown in FIG. 1 is a schematic diagram of the structure of the chiller 100 when the access door 21 is in a closed state. Figure 8 for Figure 7The sectional structural diagram of the chiller 100 along the CC section is shown in FIG. The chiller 100 comprises a housing 20 and a condenser assembly 10 as described in the above embodiment, and the condenser assembly 10 is arranged in the housing 20 .

[0072] Considering the heavy weight of the entire condenser assembly 10, it is difficult to remove the condenser assembly 10 from the housing 20. However, the heat exchange tubes 114 of the condenser assembly 10 need to be cleaned periodically due to factors such as water quality. The workload of lifting the heat exchange tubes 114 out of the housing 20 for cleaning is very large, which is inconvenient for maintenance and servicing of the chiller 100.

[0073] In order to maintain and service the chiller 100, the chiller 100 also includes an inspection door 21, which is rotatably arranged on the box body 20, and the inspection door 21 is arranged opposite to the end plate 112, and the distance between the inspection door 21 and the end plate 112 is greater than the rotation radius of the cover plate 12.

[0074] It should be noted that the relative arrangement of the inspection door 21 and the end plate 112 means that after the inspection door 21 is opened and the cover plate 12 is opened, the end plate 112 can be exposed, thereby facilitating the cleaning of the heat exchange tube 114. In addition, there are no other components between the inspection door 21 and the end plate 112 except the cover plate 12, so that the heat exchange tube 114 can be cleaned after the inspection door 21 and the cover plate 12 are opened, reducing the difficulty of cleaning the heat exchange tube 114.

[0075] In addition, the distance between the inspection door 21 and the end plate 112 is greater than the rotation radius of the cover plate 12, so that after the inspection door 21 is opened, the cover plate 12 can be removed from the end plate 112 and then the cover plate 12 can be rotated to switch the cover plate 12 from the first state to the second state.

[0076] Specifically, after the heat exchange tube 114 of the condenser assembly 10 in the utility model is pickled and softened, a brush is inserted into the heat exchange tube 114 through the inspection door 21 to clean the dirt on the inner wall of the heat exchange tube 114, and then the heat exchange tube 114 is rinsed with clean water.

[0077] Optionally, when the inspection door 21 is in a closed state, the through hole 113 has a projection toward the plane where the inspection door 21 is located, and the projection is entirely projected on the inspection door 21. That is to say, the area of ​​the inspection door 21 is relatively large and can be larger than the area occupied by the distribution area of ​​the heat exchange tubes 114, so that all the heat exchange tubes 114 can be cleaned at one time, thereby improving the cleaning efficiency of the heat exchange tubes 114.

[0078] The chiller 100 of the present invention, when the heat exchange tube 114 does not need to be cleaned, the cover plate 12 is rotated to the first state, and the cover plate 12 is connected to the end plate 112 by the connecting component 14 to achieve the closure of the cover plate 12. When the heat exchange tube 114 needs to be cleaned, the maintenance door is opened, and the cover plate 12 is switched from the first state to the second state, and water is injected into the heat exchange tube 114 to achieve the cleaning of the heat exchange tube 114, which has the characteristics of high efficiency and convenient maintenance and care.

[0079] It should be noted that the number of end plates 112 of the condenser assembly 10 described here is usually two, and the two end plates 112 are respectively arranged at the two ends of the condenser body 11 in the axial direction. The structures of the two end plates 112 are the same, and each end plate 112 is connected to a cover plate 12. Correspondingly, the number of inspection doors 21 is also two, and the connection method between the cover plate 12 and the end plate 112 is the same. The setting method of the inspection door 21 is also the same, and no detailed description is given here.

[0080] For the structures of other parts of this application, please refer to the prior art and will not be described in detail in this application.

[0081] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
