Unless otherwise specified, they do not indicate a specific order, nor do they have a specific relevance. For example, the term "first filling component" by itself does not imply the presence of a "second filling component", nor does the term "second filling component" by itself imply the presence of a "first filling component".
FIG. 1A is a perspective view of a condenser of the present application. FIG. 1B is an A-A schematic cross-sectional view of the condenser shown in FIG. 1A. FIG. 1C is a B-B schematic cross-sectional view of the condenser shown in FIG. 1A. As shown in FIGS. 1A-1C, the condenser includes a condenser shell 102. The condenser shell 102 includes a cylinder body 112, a left partition plate 116, a right partition plate 114, a left end plate 117, and a right end plate 115. The cylinder body 112 is substantially a cylinder extending in a left and right direction (i.e., a length direction). The cylinder body 112 has a central axis extending in the left and right direction. Left and right ends of the cylinder body 112 are respectively closed by the left partition plate 116 and the right partition plate 114 to form a condensation accommodating cavity 132. The left end plate 117 is substantially arc-shaped, and the left end plate 117 is connected to the left partition plate 116 to form a communication cavity 134. The right end plate 115 is also substantially arc-shaped, and the right end plate 115 is connected to the right partition plate 114. The right partition plate 114 further comprises a transverse partition plate 142 extending laterally from the right partition plate 114 to the right end plate 115, thereby forming an outlet containing cavity 152 and an inlet containing cavity 154. The condenser shell 102 also includes a medium inlet pipe 122 and a medium outlet pipe 124, the medium inlet pipe 122 and the medium outlet pipe 124 are arranged on the right end plate 115, the medium inlet pipe 122 is in fluid communication with the inlet accommodating cavity 154, and the medium outlet pipe 124 is in fluid communication with the outlet accommodating cavity 152.
As shown in FIGS. 1B-1C, the condenser further includes a first pipe bundle 162 and a second pipe bundle 164 located below the first pipe bundle 162. The first pipe bundle 162 and the second pipe bundle 164 are horizontally arranged in the condensation accommodating cavity 132. One end of the first pipe bundle 162 is in fluid communication with the communication cavity 134, and the other end of the first pipe bundle 162 is in fluid communication with the outlet accommodating cavity 152; and one end of the second pipe bundle 164 is in fluid communication with the communication cavity 134, and the other end of the second pipe bundle 164 is in fluid communication with the inlet accommodating cavity 154, so that a cooling medium can pass through the medium inlet pipe 122, then sequentially flow through the inlet accommodating cavity 154, the second pipe bundle 164, the communication cavity 134, the first pipe bundle 162, and the outlet accommodating cavity 152, and flow out of the condenser through the medium outlet pipe 124 (according to a flow direction shown by an arrow M in FIG. 1B). The condenser also includes an inlet pipe 120 and an outlet pipe 130. The inlet pipe 120 is located on an upper part of the cylinder body 112 and defines a condenser inlet on the condenser shell 102 for receiving a refrigerant gas. The outlet pipe 130 is located at a lower part of the cylinder body 112 and defines a condenser outlet on the condenser shell 102 for discharging a condensed refrigerant liquid out from the condensation accommodating cavity 132. The refrigerant gas flowing into the cylinder body 112 from the inlet pipe 120 exchanges heat with the medium in the first pipe bundle 162 and the second pipe bundle 164. After the refrigerant gas is condensed into a refrigerant liquid, the refrigerant liquid can be discharged from the cylinder body 112 through the outlet pipe 130.
As shown in FIGS. 1B-1C, the condenser also includes a subcooler 170. The subcooler 170 is arranged in the condensation accommodating cavity 132 and is arranged below the second pipe bundle 164. The subcooler 170 includes a subcooler shell 172 and a subcooler pipe bundle 174. The subcooler shell 172 is formed by extending in an axial direction of the cylinder body 112 and is connected to the left partition plate 116 and the right partition plate 114 respectively to form a subcooler accommodating cavity 176. The subcooler pipe bundle 174 is horizontally arranged in the subcooler accommodating cavity 176. One end of the subcooler pipe bundle 174 is in fluid communication with the communication cavity 134, and the other end of the subcooler pipe bundle 174 is in fluid communication with the inlet accommodating cavity 154, so that the cooling medium can pass through the medium inlet pipe 122 and then flow through the subcooler pipe bundle 174 to reach the communication cavity 134.
As shown in FIG. 1C, the subcooler 170 includes a subcooler bottom 182 and a subcooler first side portion 184 and a subcooler second side portion 186 which are located on two opposite sides of the subcooler bottom 182. A receiving space 188 is formed between the condenser shell 102 and the subcooler bottom 182, the subcooler first side portion 184, and the subcooler second side portion 186. A pair of subcooler inlets 190 are respectively arranged on the subcooler first side portion 184 and the subcooler second side portion 186, and are substantially located in a middle in the axial direction of the cylinder body 112. The refrigerant liquid in the condensation accommodating cavity 132 can enter the subcooler accommodating cavity 176 through the subcooler inlets 190 and exchange heat with the medium in the subcooler pipe bundle 174 in the subcooler accommodating cavity 176 to increase a subcooling degree of the refrigerant liquid. The outlet pipe 130 extends from a lower direction of the cylinder body 112 and is connected to the subcooler bottom 182 so that the refrigerant liquid in the subcooler accommodating cavity 176 can be discharged through the outlet pipe 130.
As shown in FIG. 1C, a radial cross-section of the subcooler 170 is substantially in a T shape. Specifically, a top surface of the subcooler 170 is substantially a plane arranged in a horizontal direction. Each of the subcooler first side portion 184 and the subcooler second side portion 186 includes a first side wall 191, a second side wall 192, a third side wall 193, a fourth side wall 194, a fifth side wall 195, and a sixth side wall 196 which are sequentially connected. The first side wall 191 is connected to the top surface of the subcooler 170. The first side wall 191, the third side wall 193, and the fifth side wall 195 are substantially arranged in a vertical direction. The second side wall 192, the fourth side wall 194, and the sixth side wall 196 are substantially arranged in the horizontal direction. Each of the pair of subcooler inlets 190 includes a vertical inlet 197 arranged on the third side wall 193 and a horizontal inlet 198 arranged on the fourth side wall 194. The vertical inlet 197 is in communication with the horizontal inlet 198.
As shown in FIG. 1C, the refrigerant liquid in the condensation accommodating cavity 132 is arranged to have a liquid level H. The liquid level H is a distance between a top surface of the refrigerant liquid in the condensation accommodating cavity 132 and the condenser outlet in the vertical direction. In the present application, the top surface of the refrigerant liquid is higher than tops of the subcooler inlets 190, thereby ensuring that the refrigerant liquid fills the subcooler accommodating cavity 176.
As shown in FIG. 1C, the condenser also includes a plurality of filling components 160 that do not chemically react with the refrigerant. The filling components 160 are arranged in the condensation accommodating cavity 132 and can occupy a portion of a volume of the condensation accommodating cavity 132. The filling components 160 are recyclable processing residues, for example, leftover materials of raw materials in a processing process. For example, materials of the recyclable processing residues are metals such as iron, aluminum, and stainless steel, rubber, plastic, etc. A shape of each filling component 160 is configured to prevent the filling component 160 from entering the subcooler accommodating cavity 176 through the subcooler inlets 190. Each filling component 160 may be in a regular shape (e.g., a cuboid, a cube, a pyramid, a cylinder, etc.) or an irregular shape. In one embodiment, a density of the filling components 160 is greater than a density of the refrigerant. The filling components 160 settle by gravity at the bottom of the condensation accommodating cavity 132, thereby occupying a portion of the volume of the condensation accommodating cavity 132. In one embodiment, the density of the filling components 160 is not greater than the density of the refrigerant. The filling components 160 are connected to the condenser shell 102 through a fastener (not shown), thereby being maintained below the liquid level of the refrigerant liquid to occupy a portion of the volume of the condensation accommodating cavity 132.
The filling components 160 in the condenser of the present application are recyclable processing residues. The filling components 160 are arranged in the condensation accommodating cavity 132, thereby occupying a portion of the volume of the condensation accommodating cavity 132. This has advantages of cost saving and ease of manufacturing. For example, in a condenser processing process, recyclable processing residues are generated. The present application fully utilizes these recyclable processing residues as the filling components 160. On the one hand, the recyclable processing residues can occupy a portion of the volume of the condensation accommodating cavity 132, thereby decreasing a filling amount of the refrigerant while maintaining the same liquid level H so as to save a cost of the refrigerant. On the other hand, the recyclable processing residues are existing materials in a processing workshop for the condenser, eliminating the need for additional procurement and processing, significantly reducing a cost of condenser production. Furthermore, the filling components 160 may also be more cost-effective processing residues from other fields, to further reduce a production cost.
FIG. 2 is B-B schematic cross-sectional view of a second embodiment of a filling component 160 of the present application. The filling component 160 shown in FIG. 2 includes a filling shell 232 and a filler 234. The filling shell 232 defines a filling accommodating cavity 236, and a plurality of access ports 238 are provided on the filling shell 232. The access ports 238 make the filling accommodating cavity 236 in communication with a condensation accommodating cavity 132, allowing a refrigerant in the condensation accommodating cavity 132 to enter the filling accommodating cavity 236. The filler 234 can occupy a portion of a volume of the filling accommodating cavity 236, thereby occupying a portion of a volume of the condensation accommodating cavity 132 so as to decrease a filling amount of the refrigerant. A shape of the filling shell 232 is configured to prevent the filling component 160 from entering a subcooler accommodating cavity 176 through a subcooler inlet 190.
In one embodiment of the present application, the filling shell 232 is a filling cage. The filling shell is made of a metal plate or a metal mesh. The filler 234 is a plurality of filling blocks. In one embodiment of the present application, the filling blocks are recyclable processing residues. for example, leftover materials of raw materials in a processing process. The recyclable processing residues do not chemically react with the refrigerant. For example, materials of the recyclable processing residues are metals such as iron, aluminum, and stainless steel, rubber, plastic, etc. The condenser of the present application uses the filling blocks to fill the filling accommodating cavity 236, to occupy a portion of the volume of the condensation accommodating cavity 132, thus decreasing a filling amount of the refrigerant while maintaining the same liquid level H, saving a cost of the refrigerant. In addition, objects of various sizes and shapes can be used as the filling blocks for filling. This significantly reduces a cost of producing the condenser. Furthermore, the filling shell 232 may be made of a flexible material. The filling shell 232 does not have a fixed shape and can therefore adapt to various shapes of subcoolers 170.
In another embodiment of the present application, the filler 234 is made of metal, polypropylene, polyvinyl chloride or high-density polyethylene.
It should be noted that while the filler 234 of the present application is a plurality of filling blocks, any filler 234 being at least one filler block is within the scope of protection of the present application.
It should also be noted that although a plurality of access ports 238 are provided on the filling shell 232 of the present application, at least one access port 238 being provided on the filling shell 232 is within the scope of protection of the present application.
FIG. 3A is a B-B schematic cross-sectional view of a condenser of the present application including a third embodiment of a filling component 160. FIG. 3B is a perspective view of a subcooler and a filling component in the condenser shown in FIG. 3A.
As shown in FIGS. 3A-3B, the filling component 160 includes a first filling component 342 and a second filling component 344. The first filling component 342 and the second filling component 344 are arranged in the receiving space 188 and are arranged on two sides of a pair of subcooler inlets 190 in the length direction of the condenser shell 102, so that an inlet channel 354 is formed between the first filling component 342 and the second filling component 344, and thus the refrigerant in the condensation accommodating cavity 132 can enter the subcooler 170 through the inlet channel 354 and the pair of subcooler inlets 190. A flow area of the inlet channel 354 is greater than or equal to a flow area of the pair of subcooler inlets 190, so that a flow rate of the refrigerant passing through the inlet channel 354 is relatively stable.
As shown in FIG. 3B, each of the first filling component 342 and the second filling component 344 includes a filling outer portion 382 located on an outside, a filling inner portion 384 located on an inside, and two filling upper portions 386. A radial cross-section of the filling outer portion 382 is substantially arc-shaped to cooperate with the inner wall of the cylinder body 112. A radial cross-section of the filling inner portion 384 is substantially in a T shape to cooperate with outer contours of the subcooler bottom 182 of the subcooler 170, the subcooler first side portion 184, and the subcooler second side portion 186. More specifically, the filling inner portion 384 cooperates with the subcooler bottom 182 of the subcooler 170, and the first side wall 191, the second side wall 192, the third side wall 193, the fourth side wall 194, the fifth side wall 195, and the sixth side wall 196 which are located on two sides of the subcooler bottom 182. The two filling upper portions 386 are respectively arranged on two sides of the subcooler 170, and are connected to the filling outer portion 382 and the filling inner portion 384. In the present application, the upper surface of the filler upper portion 386 is a plane arranged in the horizontal direction and substantially located in the same plane with the top surface of the subcooler 170.
In one embodiment of the present application, each of the first filling component 342 and the second filling component 344 includes a filling shell 232 and a filler 234. The specific structures of the filling shell 232 and the filler 234 are the same as the filling shell 232 and the filler 234 described in the second embodiment and will not be described again here.
In one embodiment of the present application, each of the first filling component 342 and the second filling component 344 is formed by at least one of extrusion molding and foam molding. In one embodiment of the present application, the first filling component 342 and the second filling component 344 are made of a polymer material, such as polypropylene, polyvinyl chloride, and high-density polyethylene. As an example, the first filling component 342 and the second filling component 344 are formed by extrusion molding. The first filling component 342 and the second filling component 344 formed by extrusion molding can match the shape of the subcooler 170. During installation by an operator, the first filling component 342, the second filling component 344 and the subcooler 170 may be installed in place first, and then the subcooler is installed into the condensation accommodating cavity 132. The installation process is convenient. As an example, the first filling component 342 and the second filling component 344 are formed by foam molding. The operator injects foam into the receiving space 188 after the subcooler 170 is installed in place. During the foaming process, the foam occupies a portion of the volume of the receiving space 188 and thus occupies a portion of the volume of the condensation accommodating cavity 132 to decrease the filling amount of refrigerant. Furthermore, since the first filling component 342 and the second filling component 344 substantially wrap the subcooler 170 in a radial cross-section, the subcooler 170 can hold the first filling component 342 and the second filling component 344 in place without other fasteners fixing the first filling component 342 and the second filling component 344.
It should be noted that although the condenser of the present application includes two filling components (i.e., the first filling component 342 and the second filling component 344), the condenser including at least one filling component is within the scope of protection of the present application.
FIG. 4 is a perspective view of a fourth embodiment of a filling component 160, and a subcooler of the present application. The similarities between the filling component shown in FIG. 4 and the filling component shown in FIGS. 3A-3B will not be described again. The main difference between the filling component shown in FIG. 4 and the filling component shown in FIGS. 3A-3B is that each of the first filling component 342 and the second filling component 344 shown in FIG. 4 also includes a filling cover portion 402. The filling cover portion 402 is located above the subcooler 170 and is connected to the filling upper portions 386 located on two sides of the subcooler 170. Thus, the first filling component 342 and the second filling component 344 are substantially in a barrel shape with a hollow portion extending in the length direction. During installation by the operator, the operator inserts the subcooler 170 into the first filling component 342 and the second filling component 344, and then installs the subcooler 170 into the condensation accommodating cavity 132.
As shown in FIG. 4, the filling cover portion 402 includes a filling cover portion exterior 412 and a filling cover portion interior 414. A bottom surface of the filling cover portion interior 414 is substantially planar so as to cooperate with the top surface of the subcooler 170. The filling cover portion exterior 412 is configured to guide the refrigerant located on an upper surface of the filling cover portion 402 to flow toward the pair of subcooler inlets 190. As an example, the upper surface of the filling cover portion exterior 412 is a plane arranged obliquely. This can divert the refrigerant so that the refrigerant flows toward the subcooler inlets 190.
It should be noted that although the condenser of the present application includes a plurality of filling components 160, the condenser including at least one filling component 160 is within the scope of protection of the present application.
It should also be noted that although the condenser of the present application includes the subcooler 170, in other embodiments, the condenser may not include the subcooler 170, and the outlet pipe 130 can be connected below the condenser shell 102 and in communication with the condensation accommodating cavity 132. A shape of the at least one filling component 160 is configured to prevent the at least one filling component 160 from leaving the condensation accommodating cavity 132 through the condenser outlet. For a condenser that does not include a subcooler 170, the at least one filling component 160 in the present application is arranged in the condensation accommodating cavity 132 and can occupy a portion of the volume of the condensation accommodating cavity 132, thereby decreasing the filling amount of refrigerant while maintaining the same liquid level H to save the cost of refrigerant.
