[0095] FIG. 3 is a top view of a solar collector device of a solar module (e.g., a solar collector panel device) according to one embodiment of the present disclosure.

[0096] FIG. 4 is a top view showing a state in which piping work has been completed on a solar module (e.g., a solar collector panel device) according to one embodiment of the present disclosure.

[0097] According to one embodiment, the solar module (30) may include an integrated solar collector (40) and a solar panel (50) disposed on the solar collector (40).

[0098] The configuration of the solar collector (40) and solar panel (50) of the solar module (30) of FIGS. 2 to 4 may be partially or entirely identical to the configuration of the solar collector (120) and solar collector (110) of the solar collector panel device (10) of FIG. 1. The embodiments of FIGS. 2 to 4 may be optionally combined with the embodiments of FIGS. 1 and 5 to 35b.

[0099] According to one embodiment, the solar panel (50) is positioned so as to be exposed to the exterior of the solar module (30) so as to obtain light energy from an external light source (e.g., sunlight). The solar panel (50) can convert the obtained light energy into electrical energy.

The thermal collector (40) can obtain thermal energy that may be generated during the process of the solar panel (50) converting light energy into electrical energy.

[0101] According to one embodiment, a plurality of solar panels (50) may be arranged on a heat collector (40). For example, the plurality of solar panels (50) may be spaced apart from each other so as to have one row and multiple columns (e.g., 1 x M, where M is a natural number) on one surface of the heat collector (40). For example, solar panel A (50a), solar panel B (50b), and solar panel C (50c) may be arranged to form one row on one surface of the heat collector (40). In general, only one solar panel is arranged on a heat collector, and a pipe connection is required for each heat collector.

For example, the solar module (30) has two solar collectors (40) arranged in parallel, and a plurality of solar panels (50) (e.g., three or more solar panels) can be attached to each solar collector (40). For example, based on two solar collectors (40), since eight pipe connection points (P) are required for each, the total number of points requiring pipe connection work can be confirmed as N x 8. (e.g., N x M, N = row, M = column, N and M are natural numbers) In general, the solar module structure in which solar panels are arranged for each solar collector can be confirmed as having a total number of points requiring pipe connection work as (4 (number of inputs and outputs required per module) x N x M) + (2 (a pair of main pipes) x M). For example, based on solar panels arranged in 5 rows and 3 columns, it can be confirmed that the solar module (30) of the present disclosure requires 40 pipe connections, compared to the 70 pipe connection points required for a typical solar module structure. Since the solar module (30) of the present disclosure has a reduced number of pipe connection points compared to typical modules, it is possible to reduce costs incurred during construction and costs incurred for maintenance.

The embodiments of FIGS. 5 to 8 may be optionally combined with the embodiments of FIGS. 1 to 4 and the embodiments of FIGS. 7 to 35b.

[0109] According to one embodiment, the solar collector (40) may include a solar collector (410), a channel part (420) including a plurality of channels (e.g., multi-channels), a pair of passages (430) arranged in parallel for input and output of a refrigerant, a via (440) formed to connect the channel part (420) and the pair of passages (430), and a support portion (450) for supporting the solar collector (40).

[0110] According to one embodiment, the collector (410), the channel portion (420), the flow path (430), the via (440), and the support portion (450) of the heat collector (40) may be an integral structure. The collector (410), the support portion (450), and the peripheral portions of the passages or holes forming the channel portion (420), the flow path (430), and the via (440) may be a monolithic support body, and the monolithic support body may have a structure in which the boundary portions of the respective components are seamlessly extended.

[0111] According to one embodiment, the collector (410), channel portion (420), flow path (430), via (440), and support portion (450) of the heat collector (40) may be formed as a single piece (or one body). The heat collector (40) is manufactured by extruding a metal having high thermal conductivity and is formed by a cutting process, and may be separated into separate elements and then joined (e.g., bonded with an adhesive material) or not assembled.

[0112] In one embodiment, the integrated heat collector (40) may be formed of the same material. For example, the integrated heat collector (40) may be manufactured by extruding aluminum (Al) having high thermal conductivity into a structure having a length of approximately 10 m or more in a single process. For example, the channel portion (420) and the flow path (430) of the integrated heat collector (40) may be manufactured using a technique used in the manufacture of general aluminum profiles, and may be designed to have various shapes and lengths.

[0113] According to one embodiment, the collector (410) of the thermal collector (40) may include a first portion (410a) and a second portion (410b) extending from the first portion (410a). The collector (410) is a portion that obtains and stores thermal energy and may be defined as a majority area of ​​the thermal collector (40) formed of aluminum (Al). The collector (410) may include an area adjacent to a solar panel (50) that is advantageous for absorbing and / or storing heat. The collector (410) may be called a manifold, a thermal collector plate, a thermal collector structure, or a heat storage structure.

[0114] According to one embodiment, the first portion (410a) may be defined as an upper portion of the collector (410), and the second portion (410b) may be defined as a lower portion of the collector (410). The second portion (410b) may be defined as a first layer of the collector (410), and the first portion (410a) may be defined as a second layer formed on or above the first layer. According to one embodiment, a plurality of solar panels (50) may be arranged on an upper surface (e.g., a surface facing the +Z axis) of the upper portion (or the second layer), and at least a portion of the channel portion (420) may be positioned within the upper portion. The upper portion may have a plate shape that supports the plurality of solar panels (50). The channel portion (420) may include a plurality of channels. According to one embodiment, the lower portion (or first layer) may have a shape in which at least a portion thereof protrudes downward (e.g., in the -Z-axis direction) from the upper portion, and may be formed to surround the flow path (430). The lower portion may be formed to protrude in a pair in a downward direction (e.g., in the -Z-axis direction) from near the edge of the upper portion, so that a pair of flow paths (430) may be positioned.

[0115] According to one embodiment, the first portion (410a) may be defined as an inner portion of the collector (410), and the second portion (410b) may be defined as an outer portion of the collector (410). For example, the first portion (410a) and the second portion (410b) of the collector (410) may be formed integrally in parallel on the same line or in one layer, in addition to being formed integrally upper and lower. At least a portion of the channel portion (420) may be positioned within the inner portion, and a flow path (430) may be positioned within the outer portion. In order for a pair of flow paths (430) to be arranged, the outer portions may be formed to extend outward from an edge of the inner portion, respectively.

[0116] According to one embodiment, the upper surface (e.g., one surface facing the +Z axis) of the first part (410a) of the solar collector (410) may include at least one recessed area (hereinafter, the first recessed area (R1)) to distinguish positions where a plurality of solar panels (50) are arranged and to be seated. For example, when solar panels A, B, and C are arranged on the upper surface of the first part (410a) of the solar collector (410), the first recessed area (R1) may be located between solar panels A and B, and between solar panels B and C. The first recessed area (R1) may be located at one end of solar panels A and C, which are arranged at the edges. According to one embodiment, the first recessed area (R1) may be an area for dividing between solar panels (50) and connecting with a frame (51) arranged to surround the solar panels (50). According to one embodiment, the first recessed area (R1) may have an inwardly fine groove shape. For example, the first recessed area (R1) may have a partially stepped shape so as to be easily combined with the frame (51) arranged to surround the solar panels (50). For example, the first recessed area (R1) may be formed to extend along a second direction (e.g., X-axis direction) that is perpendicular to the first direction (e.g., Y-axis direction).

[0117] According to one embodiment, the upper surface (e.g., one surface facing the +Z axis) of the first part (410a) of the solar collector (410) may include a recessed area (hereinafter, referred to as the second recessed area (R2)) for positioning a junction box (e.g., the junction box (57) of FIG. 11B) at the center of the area where the solar panel (50) is mounted. For example, when the solar panel A is positioned on the upper surface of the first part (410a) of the solar collector (410), the junction box (57) including the electrical signal-related components may be positioned below the solar panel A, and the junction box (57) protruding downward may be positioned within the second recessed area (R2). According to one embodiment, the second recessed area (R2) may be formed to correspond to the first recessed area (R1). For example, the second recessed area (R2) may have an inwardly fine groove shape. For example, the second recessed area (R2) may be formed to have a line shape at the center of the area where the solar panel (50) is placed. For example, the second recessed area (R2) may be formed to extend along a second direction (e.g., X-axis direction) that is perpendicular to the first direction (e.g., Y-axis direction).

[0118] However, the above-described structure is described in consideration of the arrangement of the junction box of a half-cell type solar panel (e.g., the standard size of the PV cell is cut in half and used, and the junction box is arranged between the cells), and when considering the arrangement of the junction box of a full-cell type solar panel (e.g., the standard size of the PV cell is used as is and the junction box is arranged at the edge of the cell), the second recess area (R2) may be designed to be changed to be formed at a different location of the first portion (410a).

[0119] According to one embodiment, the collector (40) may include a refrigerant-free space, a flow path (430), a channel portion (420), and a via (440).

[0120] In one embodiment, the flow path (430) of the collector (40) may be located within the second portion (410b) (e.g., the lower portion). The pair of flow paths (430) may include a first flow path (431) adjacent to one edge of the collector (410), and a second flow path (432) adjacent to the other edge of the collector (410). The first flow path (431) may be referred to as a refrigerant input flow path, and the second flow path (432) may be referred to as a refrigerant output flow path.

[0121] According to one embodiment, the first flow path (431) may have a first diameter and may be a pipe shape extending along the longitudinal direction (e.g., the first direction (e.g., the Y-axis direction)) of the heat collector (40). For example, the diameter of the first flow path (431) may be approximately 50-70Φ. One end (e.g., an opening) of the first flow path (431) may be exposed to the outside of the heat collector (40) to be connected to an external refrigerant supply pipe, and the other end of the first flow path (431) may be blocked. The first flow path (431) may include at least one opening between the one end and the other end to be connected to the channel portion (420). The refrigerant introduced through the first flow path (431) may be delivered to the channel portion (420) through the at least one opening.

[0122] According to one embodiment, the second flow path (432) may have a first diameter and may be a pipe shape extending along the longitudinal direction (e.g., the first direction (e.g., the Y-axis direction)) of the heat collector (40). The second flow path (432) may be arranged parallel to the first flow path (431). One end (e.g., an opening) of the second flow path (432) may be exposed to the outside of the heat collector (40) to be connected to an external refrigerant outlet pipe, and the other end of the second flow path (432) may be blocked. The second flow path (432) may include at least one opening between the one end and the other end to be connected to the channel portion (420). The refrigerant flowing in the channel portion (420) may be transferred to the second flow path (432) through the at least one opening and may move through the refrigerant outlet pipe. According to one embodiment, one end of the first flow path (431) for connection with the refrigerant supply pipe and one end of the second flow path (432) for connection with the refrigerant discharge pipe may be positioned in opposite directions with respect to the center of the second part (410b) of the collector (410) for easy circulation of the refrigerant.

[0123] According to one embodiment, the channel portion (420) of the heat collector (40) may be located within the first portion (410a) (e.g., the upper portion). The channel portion (420) may include a plurality of channels (e.g., multi-channels) arranged at a specified interval. The channel portion (420) is disposed below the solar panel (50), and heat generated from the solar panel (50) may be transferred to a coolant flowing in the channel portion (420) via the heat collector (410).

[0124] Referring to FIGS. 7 and 8 according to one embodiment, the channel portion (420) may include a first channel (421) connected to an opening of a first flow path (431), a second channel (422) including channels (e.g., multi-channels) branching from the first channel (421) and extending in multiple directions (e.g., forming a path, a passage, or a pipe), and a third channel (423) connected to the second channel (422) and extending in the same direction as the first channel (421) and connected to an opening of the second flow path (432). For example, the first channel (421) and the third channel (423) may extend in a second direction (e.g., an X-axis direction) that is perpendicular to the first direction (e.g., a Y-axis direction). The second channel (422) may extend in the first direction (e.g., a Y-axis direction).

[0125] Referring to FIG. 7, an area (52) for placing a solar panel (50) and an area (53) for placing a junction box (e.g., a junction box (57) of FIG. 11b) are indicated, and the arrows indicated on the right indicate the path of the refrigerant flowing within the flow path (430) and the channel portion (420).

[0126] According to one embodiment, one channel portion (420) may be formed in a size corresponding to one solar panel (50). When n solar panels (50) are arranged along a first direction (e.g., Y-axis direction), n channel portions (420) may also be formed spaced apart from each other along the first direction (e.g., Y-axis direction). For example, when solar panels A, solar panels B, and solar panels C are arranged on the upper surface of the first portion (410a) of the solar collector (410), a plurality of channel portions (420) may be formed, and may include a channel portion A arranged under solar panel A, a channel portion B arranged under solar panel B, and a channel portion C arranged under solar panel C.

[0127] According to one embodiment, one channel portion (420) may include two spaced-apart channel portions (e.g., a first channel set (420a) and a second channel set (420b)). For example, in the case of a half-cell type solar panel, considering the junction box (57) arranged at the center, the channel portion (420) may include a first channel set (420a) and a second channel set (420b) that are separated from each other with respect to a second recess area (R2). For example, the first channel set (420a) and the second channel set (420b) may be formed to be symmetrical with respect to each other with respect to the second recess area (R2) (e.g., an area where the junction boxes (57) arranged in the second direction (e.g., the X-axis direction) are located).

[0128] According to one embodiment, the first channel set (420a) and the second channel set (420b) may have a serpentine type of refrigerant flow. For example, the flow paths of the first channel set (420a) and the second channel set (420b) may be a 'continuous S shape' or a 'continuous L shape'. Hereinafter, the structure of the first channel set (420a) will be described, and the structure of the second channel set (420b) may apply the structure of the first channel set (420a).

[0129] According to one embodiment, the first channel set (420a) may include a first channel (421) extending in a first direction (e.g., Y-axis direction) according to the flow of refrigerant, a second channel (422) extending in a direction different from the first direction (e.g., second direction), and a third channel (423) extending in the first direction (e.g., Y-axis direction).

[0130] According to one embodiment, the first channel (421) may be defined as a conduit perpendicular to the first flow path (431) and / or the second flow path (432), and may be one of the passages for transferring refrigerant from the first flow path (431) to the second flow path (432). According to one embodiment, the first channel (421) may have a segmented shape. For example, the first channel (421) may include a 1-1 channel (421a) connected to an opening extending from the first flow path (431), a 1-3 channel (421c) connected to an opening extending from the second flow path (432), and a 1-2 channel (421b) spaced apart from the 1-1 channel (421a) and the 1-3 channel (421c) and connected to a plurality of channels of the second channel (422). The 1-1 channel (421a) can connect the 1st flow path (431) and the 2nd channel (422), and the 1-3 channel (421c) can connect the 2nd channel (422) and the 2nd flow path (432). The 1-2 channel (421b) can be connected to channels of the 2nd channel (422) in which the refrigerant flows in different directions.

[0131] According to one embodiment, the third channel (423) may be defined as a conduit perpendicular to the first flow path (431) and / or the second flow path (432), and may be one of the passages for transmitting refrigerant from the first flow path (431) to the second flow path (432). According to one embodiment, the third channel (423) may have a segmented shape. For example, the third channel (423) may include a 3-1 channel (423a) and a 3-2 channel (423b) which are connected to channels of the second channel (422) in which the refrigerant flows in different directions. Since the first channel (421) is directly connected to the first flow path (431) and the second flow path (432), the third channels (423) may be formed in fewer numbers than the first channel (421).

[0132] According to one embodiment, the second channel (422) includes a plurality of channels, the channels having a second diameter and having a pipe shape extending along the longitudinal direction (e.g., the first direction (e.g., the Y-axis direction)) of the collector (40). For example, the diameter of the channel may be approximately 4-5Φ. A portion of the second channel (422) may be located within the first portion (410) of the collector (410), and another portion of the second channel (422) may be located on the first portion (410a) of the collector (410).

[0133] In one embodiment, the second channel (422) may comprise a plurality of groups or bundles. Each group is defined as a bundle of multiple channels, and the channels included in a group may be pipes through which refrigerant flows in the same direction. For example, the number of channels included in a group may be approximately 4 to 7.

[0134] According to one embodiment, the channels may be designed in various shapes other than a cylindrical shape. For example, when viewed in cross-section, the channels may include protrusions that partially protrude outward from the cylindrical shape, such as a star shape, an X shape, or a pentagonal shape. The protrusions may have various shapes that can expand the contact area with the collector (410). Accordingly, the efficiency of heat circulation between the collector (410) and the refrigerant can be increased.

[0135] According to one embodiment, the second channel (422) may include a first group (422a), a second group (422b), a third group (422c), and a fourth group (422d). Each group may include multiple channels. The first group (422a) may be a passage extending from the first-first channel (421a) to the third-first channel (423a) and through which refrigerant moves toward the third-first channel (423a) (e.g., toward the right). The second group (422b) may be a passage extending from the third-first channel (423a) to the first-second channel (421b) and through which refrigerant moves toward the first-second channel (421b) (e.g., toward the left). The third group (422c) may be a passage extending from the first-second channel (421b) to the third-second channel (423b) and through which the coolant moves toward the third-second channel (423b) (e.g., toward the right). The fourth group (422d) may be a passage extending from the third-second channel (423b) to the first-third channel (421c) and through which the coolant moves toward the first-third channel (421c) (e.g., toward the left). The first, second, and third channels (421, 422, 423) may efficiently provide heat circulation as the coolant is arranged under the solar panel (50) and across the entire solar panel (50). Referring to Fig. 7, two segments of the first channel (421) and the third channel (423) are formed as one segment, but the number of each channel according to the segment is not limited thereto, and the design may be variously changed for efficient heat circulation. For example, the first-second channel (421b) of the first channel (421) may be formed in multiple numbers, the third-first channel (423a) and the third-second channel (423b) of the third channel (423) may be formed in multiple numbers, and multiple groups of the second channel (422) connected thereto may be formed in multiple numbers.

[0136] In one embodiment, when at least a portion of the channel portion (420) is located at an upper portion of the collector (410) and the first and second flow paths (431, 432) are located at a lower portion of the collector (410), the channel portion (420) and the first and second flow paths (431, 432) may partially overlap when viewed from above the collector (410). The first and second flow paths (431, 432) may be located below a portion of a plurality of channels of the second channel (422). For example, the first flow path (431) may be located below one end of the first channel (421) (e.g., the first-first channel (421a)) and a portion of the second channel (422) (e.g., a portion of the first group (422a)). For example, a second flow path (432) may be located below the other end of the first channel (421) (e.g., the 1st-3rd channel (421c)) and a portion of the second channel (422) (e.g., a portion of the 4th group (422d)).

[0137] According to one embodiment, the channel portion (420) may be positioned within the upper portion of the collector (410) or may be formed by the upper portion and the cover member (e.g., the cover member (72) of FIG. 11A). For example, the second channel portion (422) may be formed as a channel or path penetrating the interior of the upper portion of the collector (410). For example, at least a portion of the first channel portion (421) and the third channel portion (423) may be formed as a channel or path surrounded by the upper surface of the upper portion and the inner side of the cover member (72). For example, at least a portion of the first channel portion (421) and the third channel portion (423) may be formed by a recessed area of ​​the collector (410) (e.g., the first recessed area (R1) and the second recessed area (R2)) and an inner groove of the cover member (72) covering a portion of the recessed area.

[0138] According to one embodiment, a via (440) of the collector (40) may be formed to penetrate between the first portion (410a) and the second portion (410b) of the collector (410) to connect the channel portion (420) and a pair of flow paths (430). The via (440) may include a first via (441) connecting one end of the first flow path (431) and the first channel (421), and a second via (442) connecting the other end of the second flow path (432) and the first channel (421). For example, the first via (441) is connected to an opening formed at one end of the first-1 channel (421a) extending in a second direction (e.g., X-axis direction) from an opening of the first flow path (431) extending in a first direction (e.g., Y-axis direction), and may extend in a third direction (e.g., Z-axis direction) perpendicular to the first direction (e.g., Y-axis direction) and the second direction. The refrigerant introduced into the first flow path (431) may be transferred to the first-1 channel (421a) through the first via (441). For example, the second via (442) may be connected to an opening formed at one end of the first-third channel (421c) extending in a second direction (e.g., X-axis direction) from an opening of the second flow path (432) extending in a first direction (e.g., Y-axis direction), and may extend in a third direction (e.g., Z-axis direction) perpendicular to the first direction (e.g., Y-axis direction) and the second direction (e.g., X-axis direction). The refrigerant provided from the first-third channel (421c) may be transferred to the second flow path (432) through the second via (442).

[0139] In one embodiment, the via (440) can be formed to at least partially penetrate the first portion (410a) or the second portion (410b) of the collector (410). In one embodiment, a portion of the via (440) can be formed by a portion of the cover member (72) that covers a portion of a recessed area (e.g., the first recessed area (R1) and the second recessed area (R2)) of the collector (410). For example, a portion of the via (440) can be formed by the first portion (410a) of the collector (410) and a portion of the cover member (72). For example, a portion of the via (440) can be formed by the second portion (410b) of the collector (410).

[0140] According to one embodiment, the support portion (450) of the heat collector (40) forms a part of the second portion (410b) of the heat collector (410) and may extend in the longitudinal direction of the heat collector (40) to support the heat collector (40) as a whole. According to one embodiment, the support portion (450) is formed to surround a pair of flow paths (430) and may be formed in parallel below both edges of the first portion (410a). For example, the support portion (450) may include a first support portion (451) protruding downward (e.g., in the -Z-axis direction) from one side of the first portion (410a) and a second support portion (452) protruding downward (e.g., in the -Z-axis direction) from the other side of the first portion (410a).

[0141] In one embodiment, the support portion (450) may include a first region (450a) forming a wall of the duct (430) and a second region (450b) extending from the first region (450a) toward a support surface (e.g., the ground or an outer wall (roof) of a building) to substantially support the heat collector (40). In one embodiment, the second region (450b) of the support portion (450) may be disposed on a flat plate (e.g., an insulating sheet (60)) that contacts or is disposed on the support surface to support the heat collector (40).

[0142] According to one embodiment, the support portion (450) can extend in a first direction (e.g., Y-axis direction) of the heat collector (40). For example, in general, solar modules are designed with separate supports in the major axis direction (e.g., length direction) and the minor axis direction to support the heat collector. Since the support portion (450) of the present disclosure is formed as a part of the heat collector (40), the heat collector (40) can be stably supported from the support surface without a separate major axis direction (e.g., Y-axis direction) support.

[0143] In one embodiment, the solar collector (40) may include a fastening protrusion (480) for coupling with another component (e.g., another solar collector, a short support, or a solar panel (50)). The fastening protrusion (480) may be formed adjacent to the outside of the solar collector (40). For example, the fastening protrusion (480) may be shaped to protrude outward from the edge of the solar collector (410).

[0144] According to one embodiment, the fastening projection (480) of the heat collector (40) may include a first projection portion (481) for coupling with another heat collector (40a). For example, the first projection portion (481) may be positioned adjacent to the support portion (450). For example, the heat collector (40) and the other heat collector (40a) may each have a first projection portion (481) formed thereon and may be coupled through a fastening component (e.g., a coupling member) such as a clamp.

[0145] According to one embodiment, the fastening protrusion (480) of the solar collector (40) may include a second protrusion portion (482) for coupling with the solar panel (50) or for coupling with a short-axis support (e.g., the short-axis support (91) of FIG. 24). The second protrusion portion (482) may protrude from one side of the solar collector (410) and the first protrusion portion (481) may protrude from the other side of the solar collector (410). When the second protrusion portion (482) is positioned adjacent to the first flow path (431), the first protrusion portion (481) may be positioned adjacent to the second flow path (432). The second protrusion portion (482) has a shape extending in the short-axis direction (e.g., the X-axis direction), and a part of the second protrusion portion (482) may be coupled with the solar panel (50) and the other part may be coupled with the short-axis support (91).

[0146] In one embodiment, the solar panel (50) may be covered by a frame (51), and a portion of the second protruding portion (482) of the solar collector (40) and the frame (51) may be coupled via a fastening member such as a clamp. In one embodiment, another portion of the second protruding portion (482) of the solar collector (40) and the short support (91) may be coupled via a fastening member such as a clamp.

[0147] According to one embodiment, the heat collector (40) may include a support portion expansion hole (490). The expansion hole (490) is formed to expand the heat collector (40) in the longitudinal direction (e.g., Y-axis direction) and may be arranged parallel to the support portion (450). For example, the expansion hole (490) may be located between the first support portion (450) and the second support portion (450). The expansion hole (490) may be formed by a hole wall extending downward from the first portion (410a) of the heat collector (410). For example, by inserting an expansion frame (e.g., an expansion frame (93) of FIG. 28) into the expansion hole (490) located below each of the two heat collectors (40) to connect the two heat collectors (40), the entire heat collector (40) may be expanded in the longitudinal direction.

[0148] In one embodiment, the solar module (30) may include an insulating sheet (60). The insulating sheet (60) includes an insulating material and can efficiently store energy transmitted from the solar panel (50). The insulating sheet (60) may be plate-shaped and may be positioned beneath the heat collector (40). For example, the insulating sheet (60) may be bonded and positioned beneath the support portion (450).

[0149] According to one embodiment, the solar module (30) may include an insulating material (not shown) disposed adjacent to the collector (410). The insulating material may be positioned below the first portion (410a). The insulating material may be disposed between the second portions (410b) disposed in a pair. For example, the solar module (30) may have a space surrounded by the first portion (410a) and the second portion (410b), and as the insulating material is disposed within the space, the thermal energy stored within the solar module (30) may be efficiently stored. For example, when the insulating sheet (60) is disposed below the support portion (450), the insulating material may be filled within the space surrounded by the first portion (410a), the second portion (410b) and the insulating sheet (60) of the collector (410).

[0150] FIG. 9 is a schematic diagram illustrating the structure of the channels and the flow paths of a heat collection device according to one embodiment of the present disclosure.

[0151] In one embodiment, a solar module (e.g., solar module (30) of FIG. 2) may include an integrated solar collector (e.g., solar collector (40) of FIG. 2) and a plurality of solar panels (e.g., solar panels (50) of FIG. 2) disposed over the solar collector (40).

[0152] According to one embodiment, the solar collector (40) may include a solar collector (e.g., the solar collector (410) of FIG. 6), a channel part (620) including a plurality of channels formed to allow a refrigerant to flow within the solar collector (410), a pair of passages (430) arranged in parallel for input and output of the refrigerant, and a via (440) formed to connect the channel part (620) and the pair of passages (430).

[0153] The configuration of the channel portion (620), the pair of flow paths (430), and the via (440) of the heat collector (40) of FIG. 9 may be partially or entirely identical to the configuration of the channel portion (420), the pair of flow paths (430), and the via (440) of the heat collector (40) of FIGS. 5 to 8. The embodiment of FIG. 9 may be optionally combined with the embodiments of FIGS. 1 to 8 and the embodiments of FIGS. 10 to 35b.

[0154] The configuration of the channel section (620), a pair of flow paths (430), and a via (440) of the heat collection device (40) of Fig. 9 may be a parallel riser type, unlike the configuration of Fig. 7 (e.g., serpentine type). Hereinafter, the differences from the configuration of Fig. 7 will be described.

[0155] In one embodiment, the flow path (430) of the collector (40) may be located within the second portion (410b) (e.g., the lower portion). The pair of flow paths (430) may include a first flow path (431) adjacent to one edge of the collector (410), and a second flow path (432) adjacent to the other edge of the collector (410).

[0156] According to one embodiment, the channel portion (620) of the collector device (40) may be located within the first portion (410a) (e.g., the upper portion).

[0157] According to one embodiment, the channel portion (620) may include a first channel (621) connected to an opening of the first flow path (431), a second channel (622) including channels branching from the first channel (621) and extending in a plurality of directions, and a third channel (623) connected to the second channel (622) and extending in the same direction as the first channel (621) and connected to the opening of the second flow path (432). For example, the first channel (621) and the third channel (623) may extend in a second direction (e.g., an X-axis direction) that is perpendicular to the first direction (e.g., a Y-axis direction). The second channel (622) may extend in the first direction (e.g., a Y-axis direction).

[0158] Referring to FIG. 9, an area (52) for placing a solar panel (50) and an area (53) for placing a junction box (e.g., junction box (57) of FIG. 11b) are indicated, and the arrows indicated on the right indicate the path of the refrigerant flowing within the flow path (430) and the channel portion (620).

[0159] According to one embodiment, one channel section (620) may include two spaced apart channel sections (e.g., a first channel set (620a) and a second channel set (620b)). For example, in the case of a half-cell type solar panel, the first channel set (620a) and the second channel set (620b) may be separated from each other, taking into account the junction box (57) positioned at the center.

[0160] According to one embodiment, the first channel set (620a) and the second channel set (620b) may have a parallel riser type of refrigerant flow. Hereinafter, the structure of the first channel set (620a) will be described, and the structure of the second channel set (620b) may apply the structure of the first channel set (620a).

[0161] According to one embodiment, the first channel set (620a) may include a first channel (621) extending in a first direction (e.g., Y-axis direction) according to the flow of refrigerant, a second channel (622) extending in a second direction (e.g., X-axis direction) perpendicular to the first direction, and a third channel (623) extending in the first direction (e.g., Y-axis direction).

[0162] According to one embodiment, the first channel (621) may be defined as a conduit perpendicular to the first flow path (431) and / or the second flow path (432), and may be one of the passages for transferring refrigerant from the first flow path (431) to the second flow path (432). According to one embodiment, the first channel (621) may be a passage shape that is not segmented but connected as one. The first channel (621) may include one end connected from the first flow path (431) and openings connected to a plurality of channels of the second channel (622). The first channel (621) may be connected to channels of the second channel (622) in which the refrigerant flows in the same direction.

[0163] According to one embodiment, the third channel (623) may be defined as a conduit perpendicular to the first flow path (431) and / or the second flow path (432), and may be one of the passages for transmitting refrigerant from the first flow path (431) to the second flow path (432). According to one embodiment, the third channel (623) may be a passage shape that is not segmented but connected as one. The third channel (623) may include openings connected to a plurality of channels of the second channel (622) and an end connected from the second flow path (432). The third channel (623) may be connected to channels of the second channel (622) in which the refrigerant flows in the same direction.

[0164] According to one embodiment, the second channel (622) may include a plurality of channels and may be in the shape of a conduit extending along the longitudinal direction (e.g., the first direction (e.g., the Y-axis direction)) of the heat collector (40).

[0165] In one embodiment, the second channel (622) may comprise a plurality of groups or bundles. Each group is defined as a bundle of multiple channels, and the channels included in a group may be pipes through which refrigerant flows in the same direction. For example, the number of channels included in a group may be approximately 4 to 7.

[0166] According to one embodiment, the second channel (622) may include a first group (622a), a second group (622b), a third group (622c), and a fourth group (622d). Each group may include multiple channels. The first group (622a), the second group (622b), the third group (622c), and the fourth group (622d) may be arranged in parallel. The first group (622a), the second group (622b), the third group (622c), and the fourth group (622d) may be passages extending from the first channel (621) to the third channel (623) and through which refrigerant moves (e.g., toward the right) toward the third channel (623). For example, the first group (622a), the second group (622b), the third group (622c), and the fourth group (622d) may be arranged sequentially from one end of the first channel (621) (e.g., the portion connected to the first flow path (431)) toward the other end. For example, the first group (622a), the second group (622b), the third group (622c), and the fourth group (622d) may be arranged sequentially from one end of the third channel (623) toward the other end (e.g., the portion connected to the second flow path (432)).

[0167] According to one embodiment, the first, second, and third channels (621, 422, 423) can efficiently provide heat circulation by arranging the refrigerant under the solar panel (50) and across the entire solar panel (50). Referring to FIG. 9, the group of second channels (622) is disclosed as four, but is not limited thereto, and can be formed in four or more groups to increase thermal efficiency.

[0168] According to one embodiment, a via (440) of the collector (40) may be formed to penetrate between the first portion (410a) and the second portion (410b) of the collector (410) to connect the channel portion (620) and a pair of flow paths (430). The via (440) may include a first via (441) connecting the first flow path (431) to one end of the first channel (621), and a second via (442) connecting the second flow path (432) to one end of the third channel (623). For example, a first via (441) is connected from an opening of a first flow path (431) extending in a first direction (e.g., Y-axis direction) to an opening formed at one end of a first channel (621a) extending in a second direction (e.g., X-axis direction), and may extend in a third direction (e.g., Z-axis direction) perpendicular to the first direction (e.g., Y-axis direction) and the second direction. A refrigerant introduced into the first flow path (431) may be transferred to the first channel (621) through the first via (441). For example, a second via (442) may be connected from an opening of a second flow path (432) extending in a first direction (e.g., Y-axis direction) to an opening formed at one end of a third channel (623) extending in a second direction (e.g., X-axis direction), and may extend in a third direction (e.g., Z-axis direction) perpendicular to the first direction (e.g., Y-axis direction) and the second direction (e.g., X-axis direction). Coolant provided from the third channel (623) may be transferred to the second flow path (432) through the second via (442).

[0169] In one embodiment, the via (440) can be formed to at least partially penetrate the first portion (410a) or the second portion (410b) of the collector (410). In one embodiment, the via (440) can be formed by a portion of a cover member (72) that covers a portion of a recessed area of ​​the collector (410). For example, the via (440) can be formed by the second portion (410b) of the collector (410) and a portion of the cover member (72). For example, the via (440) can be formed by the first portion (410a) and the second portion (410b) of the collector (410) and a portion of the cover member (72).

[0170] FIG. 10 is a top view of a solar module according to one embodiment of the present disclosure.

[0171] FIG. 11A is a drawing showing a section between solar panels (P1) taken along line AA` of FIG. 10 according to one embodiment of the present disclosure.

[0172] FIG. 11b is a drawing showing a separated middle portion (P2) of one of the solar panels cut along line AA` of FIG. 10 according to one embodiment of the present disclosure.

[0173] According to one embodiment, the solar module (30) may include an integrated solar collector (40) and a plurality of solar panels (50) disposed on the solar collector (40).

For example, solar panels A (50a), B (50b), and C (50c) may be arranged on the upper surface of a first portion (410a) (e.g., an upper portion) of the solar collector (410).

[0176] In one embodiment, a plurality of solar panels (50) may be covered by frames (51) to protect the panels and facilitate coupling with the solar collector (40).

[0178] According to one embodiment, the S1 region and the S2 region may be spaced apart from each other. The space between the S1 region and the S2 region may be formed as a recessed region (e.g., a first recessed region (R1)). According to one embodiment, the first recessed region (R1) may have an inwardly fine groove shape. For example, the first recessed region (R1) may have a partially stepped shape so as to be easily combined with a frame (51) arranged to surround the solar panel (50). According to one embodiment, by maintaining a state in which a portion of the frame A (51a) and the frame B (51b) are inserted within the first recessed region (R1), the solar panel A (50a) and the solar panel B (50b) may be stably mounted on the solar collector (410).

[0179] According to one embodiment, a sealing member (71) may be disposed in a space spaced between solar panels A (50a) and B (50b). For example, the sealing member (71) may be disposed along a second direction (e.g., X-axis direction) on the heat collector (40). The sealing member (71) seals the space between solar panels A (50a) and B (50b), thereby limiting or reducing heat from being released from the heat collector (40) as air passes through the space. The sealing member (71) seals the space between solar panels A (50a) and B (50b), thereby limiting or reducing contaminants such as rainwater or dust from entering between solar panels A (50a) and B (50b).

[0180] Referring to FIG. 11A, a flow path (430), a channel portion (420), and a via (440) connecting the flow path (430) and the channel portion (620) are disclosed. The flow path (430) is formed to penetrate a second portion (410b) (e.g., a lower portion) of the collector (410) and may extend to pass under the solar panel A (50a) and the solar panel B (50b). The channel of the channel portion (620) may have a thickness (e.g., a diameter) smaller than that of the flow path (430) and may extend to separate the first portion (410a) (e.g., an upper portion) of the collector (410) on which the solar panel A (50a) is disposed and the first portion (410a) (e.g., an upper portion) of the collector (410) on which the solar panel B (50b) is disposed.

The solar panel B (50b) is covered by the frame B (51b) and can be arranged on the upper surface (e.g., one surface facing the +Z axis) of the frame B (51b). A junction box (57) is arranged on the lower surface (e.g., one surface facing the -Z axis) of the frame B (51b), and the junction box (57) can be arranged along the space between the B-1 panel (B1) and the B-2 panel (B2) so as not to overlap with the B-1 panel (B1) and the B-2 panel (B2).

[0183] According to one embodiment, a portion of the collector (410) may include a recessed area (e.g., a second recessed area (R2)) for a space in which a junction box (57) is positioned. The second recessed area (R2) may be formed between the B-1 panel (B1) and the B-2 panel (B2). The junction box (57) may be maintained in a fully inserted state within the second recessed area (R2).

[0184] Referring to FIG. 11B, a flow path (430) and a channel portion (620) are disclosed. The flow path (430) is formed to penetrate a second portion (410b) (e.g., a lower portion) of the solar collector (410) and may extend to pass under the B-1 panel (B1) and the B-2 panel (B2). The channel portion (620) may have a thickness (e.g., a diameter) smaller than that of the flow path (430) and may extend to separate the first portion (410a) (e.g., an upper portion) of the solar collector (410) on which the solar panel A (50a) is arranged and the first portion (410a) (e.g., an upper portion) of the solar collector (410) on which the solar panel B (50b) is arranged. In one embodiment, a via (440) extending from the filament (430) to the channel portion (620) under the solar panel A (50a) may be formed by a portion of the second portion (410b) (e.g., the lower portion) of the collector (410) and a cover member (72). In one embodiment, a via (440) extending from the filament (430) to the channel portion (620) under the solar panel B (50b) may be formed by a portion of the second portion (410b) (e.g., the lower portion) of the collector (410) and a cover member (72).

[0186] According to one embodiment, the solar module (30a) may include an integrated heat collector (40) and a glass panel (70) disposed over the heat collector (40).

[0187] According to one embodiment, the solar collector (40) may include a solar collector (410), a channel part (420) including a plurality of channels, a pair of passages (430) arranged in parallel for input and output of a refrigerant, a via (e.g., a via (440) of FIG. 7) formed to connect the channel part (420) and the pair of passages (430), and a support portion (450) for supporting the solar collector (40).

[0188] According to one embodiment, the collector (410), the channel portion (420), the flow path (430), the via (440), and the support portion (450) of the collector (40) may be an integral structure. The peripheral portion of the passage or hole forming the collector (410), the channel portion (420), the flow path (430), and the via (440) may be a monolithic support body, and the boundary portions of the respective components of the monolithic support body may be a structure in which they are seamlessly extended.

[0207] Figures 13 to 23b illustrate a manufacturing process of a heat collection device (40) of a solar module (30).

[0208] In one embodiment, a solar module (e.g., solar module (30) of FIG. 2) may include an integrated solar collector (e.g., solar collector (40) of FIG. 2) and a plurality of solar panels (e.g., solar panels (50) of FIG. 2) disposed over the solar collector (40).

[0209] According to one embodiment, the heat collector (40) may include a heat collector (e.g., heat collector (410) of FIG. 6), a channel portion (e.g., channel portion (420) of FIG. 6) including a plurality of channels formed to allow refrigerant to flow within the heat collector (410), a pair of channels (e.g., channel portion (430) of FIG. 6) arranged in parallel for input and output of the refrigerant, and a via (e.g., bar (440) of FIG. 6) formed to connect the channel portion (420) and the pair of channels (430).

[0210] The configuration of the collector (410), the channel portion (420), the pair of flow paths (430), and the via (440) manufactured in the process of the collector device (40) of FIGS. 13 to 23b may be partially or entirely identical to the configuration of the collector (410), the channel portion (420), the pair of flow paths (430), and the via (440) of the collector device (40) of FIGS. 5 to 11b. The embodiment of FIGS. 13 to 23b may be optionally combined with the embodiment of FIGS. 1 to 12 and the embodiment of FIGS. 24 to 35b.

[0211] Referring to process 10 of FIG. 13 and FIG. 14, as a process for manufacturing a heat collector (40) of a solar module (30), the heat collector (40) can be manufactured by extruding a metal with high thermal conductivity. For example, the manifold plate (81) can be preferentially manufactured using an extrusion method for manufacturing an aluminum profile.

[0212] According to one embodiment, the manifold plate (81) is formed integrally, and may be formed into a single piece (or one body) of the collector (410), the channel portion (420), the flow path (430), and the support portion (450), for example, through an extrusion process. The collector (410), the channel portion (420), the flow path (430), and the support portion (450) may have a shape that is partially different from that of the completed collector device (40) before processing.

[0213] In one embodiment, the integral manifold plate (81) may be formed entirely of the same material. For example, by extruding aluminum (Al) with high thermal conductivity, a structure having a length of approximately 10 m or more can be manufactured in a single process.

[0214] Referring to process 20 of FIG. 13 and FIG. 14, the manufactured manifold plate (81) can be manufactured into a manifold primary processing plate (82) by cutting a portion thereof. The manifold primary processing plate (82) can guide an area where solar panels (50) are mounted. The manifold primary processing plate (82) can be manufactured by cutting out an area of ​​the manifold plate (81) that overlaps or interferes with the frame (e.g., frame (51) of FIG. 11a) and junction box (e.g., junction box (57) of FIG. 11b) of the solar panel (50) through a NC (numerical control) processing process.

[0215] According to one embodiment, the manifold primary processing plate (82) can process the middle portions of the upper surface of the manifold plate (81). For example, the manifold primary processing plate (82) can form at least one recessed area (hereinafter, a first recessed area (R1)) to distinguish positions where a plurality of solar panels (50) are arranged and mounted on the upper surface of the solar collector (410). For example, the manifold primary processing plate (82) can form a recessed area (hereinafter, a second recessed area (R2)) for positioning a junction box (57) in the center of the area where the solar panels (50) are mounted on the upper surface of the solar collector (410).

[0216] Referring to process 30 of FIG. 13 and FIGS. 16 to 19, a manifold primary processing plate (82) can be manufactured into a manifold secondary processing plate (83) by additionally cutting a portion thereof. The manifold secondary processing plate (83) can provide a path for connecting the flow path (430) and the channel portion (420). For example, the manifold secondary processing plate (83) can be manufactured by a die-cutting process using NC (numerical control) processing for forming a portion of the channel portion (420) of the manifold primary processing plate (82) and forming a via (440).

[0217] According to one embodiment, the order of process 20 (e.g., manifold primary processing plate (82) forming process) and process 30 (e.g., manifold primary processing plate (82) forming process) may be interchanged.

[0218] According to one embodiment, the manifold secondary processing plate (83) can be formed by cutting an end portion (e.g., a side portion) of the manifold primary processing plate (82). Fig. 15 illustrates an end portion of the manifold primary processing plate (82).

[0219] Referring to FIG. 17 according to process 31, an end portion of a manifold primary processing plate (82) can be NC (numerical control) processed. The manifold primary processing plate (82) includes an upper portion and a lower portion, and an end portion of the upper portion (e.g., a portion where the channel portion (420) is located) can be step-processed. Through the step-processing, the manifold primary processing plate (82) can include a first step (82a) formed such that a side surface arranged to surround the channel portion (420) and an upper surface of the upper portion are perpendicular to each other, and a second step (82b) formed such that a side surface arranged to surround the channel portion (420) and an upper surface of the lower portion are perpendicular to each other. The first step (82a) can serve as a reference line for a process (e.g., a post-processing process) to cut off the solidified welding liquid that has overflowed to the upper surface when the cover member (72) for forming the via (440) is joined (e.g., welded) to the collector. Accordingly, the welded portion can be prevented from contacting the solar panel (50).

[0220] Referring to FIG. 18 according to process 32, an end portion of a manifold primary processing plate (82) can be additionally NC-processed. In the manifold primary processing plate (82) having first and second steps (82a, 82b), a channel including a plurality of microchannels (e.g., the second channel (422) of FIG. 7) can include a plurality of groups or bundles that are distinguished according to the direction in which the refrigerant flows or are connected to other channels (e.g., the first channel (421) and the third channel (423) of FIG. 7). In the manifold primary processing plate (82) having first and second steps (82a, 82b), a partition wall (82c) can be NC-processed to divide the connection space between the respective groups. The NC processing can be performed by taking out a space other than the partition wall (82c).

[0221] Referring to FIG. 19 according to process 33, an end portion of a manifold primary processing plate (82) can be additionally NC-processed. In the manifold primary processing plate (82) having formed first and second steps (82a, 82b) and a partition wall (82c), a via (440) can be formed to connect a flow path (430) located at a lower portion and a channel portion (420) (e.g., multiple channels) located at an upper portion. The NC processing for forming the via (440) can be performed by drilling. In addition, a screw groove for connecting the flow path (430) and various piping connectors can also be processed.

[0222] Referring to process 40 of FIG. 13, FIG. 20a and FIG. 20b, a manifold secondary processing plate (83) can be combined with a cover member (72) to manufacture a heat collector (40). The cover member (72) of the heat collector (40) can provide a path connecting an opening extending from a flow path (430) and a portion of a channel portion (420) (e.g., a second channel (422)). For example, the heat collector (40) can form a portion of a channel portion (420) (e.g., a first channel (421) and a third channel (423) of FIG. 7) by combining a cover member (72) in a manifold secondary processing plate (83).

[0223] According to one embodiment, the cover member (72) can be manufactured through a separate extrusion process, and the cross-section of the cover member (72) can have a recessed shape (e.g., a quarter-circle shape) for forming a channel. The cover member (72) can be joined (e.g., welded) to the upper portion of the manifold secondary processing plate (83). The cover member (72) can be fitted between each of the partition walls (82c). The opening of the flow path (430) can be connected to at least one recessed space of the cover member (72). The recessed space of the cover member (72), the stepped surface of the upper portion, and the space where the peripheral side surfaces of the channels are formed can form a part of the channel portion (420) (e.g., the first channel (421) and the third channel (423) of FIG. 7).

[0224] According to one embodiment, the cover member (72) may be placed in a first recessed area (R1) formed between a plurality of solar panels (50). The cover member (72) may be placed in a second recessed area (R2) where the junction box (57) of each solar panel (50) is located.

[0225] Referring to process 50 of FIG. 13 and FIG. 21, a process of placing an insulating sheet (60) at the bottom of a heat collector (40) can be performed. The insulating sheet (60) can be attached to the lower surface of the lower portion (e.g., the support portion (450)) of the heat collector (40) to limit or reduce heat absorbed by the heat collector (40) from escaping toward the lower portion. The insulating sheet (60) can be in the shape of a plate. A coating sheet or reflective film that reflects infrared rays can be attached to the surface of the insulating sheet (60) to enhance the insulating performance.

[0226] According to one embodiment, the space between the heat collector (40) and the insulation sheet (60) can be filled with insulation material to improve insulation performance.

[0227] Referring to process 60 of FIG. 13, FIG. 22a, and FIG. 22b, a process of arranging multiple solar collectors (40) in parallel and connecting them to each other can be performed. One solar collector (40) can be manufactured so that multiple solar panels (50) are arranged, or a structure in which two solar collectors (40) are combined can be manufactured so that multiple solar panels (50) are arranged.

[0228] In general, the manufacturing cost may increase significantly when the width of the manifold plate (e.g., the manifold plate (81) of FIG. 13) is processed through an extrusion method so that it corresponds to (e.g., is large) the width of the solar panel (50). Accordingly, the width of the manifold plate (81) may be manufactured to be narrower than the width of the solar panel (50), and after the heat collector (40) is manufactured, a plurality of heat collectors (40) (e.g., two) may be combined to manufacture them so that they correspond to the width of the solar panel (50).

[0229] According to one embodiment, the coupling of a plurality of (e.g., two) heat collectors (40) can be performed by facing the fastening protrusions (480) (e.g., the first protrusion portion (481)) of each heat collector (40) and connecting them with a fastening member (85) such as a clamp. The fastening member (85) is not limited to a clamp, and can be performed in various ways such as bolt and nut fastening and welding that can connect and fix the heat collectors (40).

[0230] According to one embodiment, the heat collectors (40) having a left-right asymmetrical structure can be combined to form a left-right symmetrical shape. For example, the heat collectors (40) may have a first protrusion (481) formed on one side and a second protrusion (482) formed on the other side. The first protrusion (481) may be a part for combining the heat collectors (40) with each other, and the second protrusion (482) may be a part for combining with a short support or a solar panel (50). Accordingly, the two heat collectors (40) can be combined in a left-right symmetrical shape by arranging the first protrusions (481) to face each other. However, the arrangement of the protrusions is not limited to the above structure, and the shape and arrangement of the protrusions can be designed in various ways, and the heat collectors (40) can be combined while being arranged in parallel with each other.

[0231] Referring to process 70 of FIG. 13, FIG. 23a, and FIG. 23b, one end of the flow path (430) of the heat collector (40) can be fastened with a connector (87) to be connected to a refrigerant supply pipe or a refrigerant discharge pipe. The other end of the flow path (430) of the heat collector (40) can be fastened with a plug (88) to block the opening of the refrigerant flow path (430).

[0232] Afterwards, the manufactured integrated heat collector (40) can be used as a solar module (30) after performing a function test such as a leak test.

[0233] The integrated heat collector (40) manufactured through the above process can be installed at the installation site by first installing the heat collector (40), then installing and testing various systems related to the operation of the heat collector (40), and then inspecting the operation of the solar panel (50) and the related electrical system. Accordingly, the thermal and electrical parts of the solar module (30) can be constructed separately. During construction, the thermal and electrical parts can be separated, allowing for separate operation by respective materials and engineers, thereby effectively managing the on-site work schedule.

[0249] FIG. 35b is an enlarged cross-sectional view of an end region of the heat collection device of FIG. 34 according to one embodiment of the present disclosure.

[0250] In one embodiment, a solar module (e.g., solar module (30) of FIG. 2) may include an integrated solar collector (e.g., solar collector (40) of FIG. 2) and a plurality of solar panels (e.g., solar panels (50) of FIG. 2) disposed over the solar collector (40).

[0251] According to one embodiment, the heat collector (40) may include a heat collector (e.g., heat collector (410) of FIG. 6), a channel portion (e.g., channel portion (420) of FIG. 6) including a plurality of channels formed to allow refrigerant to flow within the heat collector (410), a pair of channels (e.g., channel portion (430) of FIG. 6) arranged in parallel for input and output of the refrigerant, and a via (e.g., bar (440) of FIG. 6) formed to connect the channel portion (420) and the pair of channels (430).

[0252] Figures 23 to 35b illustrate the construction process of a solar module (30).

[0253] According to one embodiment, a first method for constructing a solar module (30) may be performed by installing a solar collector (40) on a support surface (e.g., the ground or an outer wall (roof) of a building) at a site (e.g., outside), and then arranging and joining solar panels (50). A second method for constructing a solar module (30) may be performed by joining solar panels (50) on a solar collector (40) in a factory, then transporting them to a site in an array form, and then assembling them on a support surface (e.g., the ground or an outer wall (roof) of a building). Hereinafter, the first method will be described, and the assembly process of the second method applies the assembly process of the first method.

[0254] The configuration of the collector (410), the channel portion (420), the pair of flow paths (430), the via (440), and the support portion (450) of the heat collection device (40) initiated by the construction process of FIGS. 23 to 35b may be partially or entirely identical to the configuration of the collector (410), the channel portion (420), the pair of flow paths (430), the via (440), and the support portion (450) of the heat collection device (40) of FIGS. 5 to 22b. The embodiment of FIGS. 23 to 35b may be optionally combined with the embodiment of FIGS. 1 to 22b.

[0255] Referring to Fig. 23, a short-axis support (91) can be placed and assembled on a support surface (e.g., the ground or an outer wall (roof) of a building) to install a solar module (30). Generally, in order to install a solar module, a long-axis support must be installed in addition to a short-axis support. However, since the solar module (30) according to the present disclosure has a long-axis support (e.g., support portion (450)) manufactured as an integral part within the heat collection device (40), it can provide cost and time savings by installing only the short-axis support (91).

[0256] According to one embodiment, in order to accurately place the integrated heat collector (40) on the rail corresponding to the short-axis support (91), a positioning reference point (O) may be installed on the outer short-axis support (91). The positioning reference point (O) may be a structure that can slide on the rail and be fitted to a part of the heat collector (40). For example, when two integrated heat collectors (40) for a 3 x 1 array are installed to install solar modules (30) in a total 3 x 2 array form, the positioning reference point (O) may be placed at a position intersecting the installation reference line within each outer short-axis support (91).

[0257] Referring to Fig. 25a, an integrated heat collector (40) (e.g., a first heat collector (41)) can be arranged in accordance with a positioning reference point (O). The heat collector (40) can be arranged and combined in one or more (e.g., two) to correspond to the size of the solar panel (50). For example, when the width of two heat collectors (40) corresponds to the width of the solar panel (50), a first heat collector (41) in which two heat collectors (40) are combined can be used. In the first heat collector (41), the positioning reference point (O) can be inserted into a space between the two combined heat collectors (40) to determine the position of the first heat collector (41). For example, when the width of one heat collector (40) corresponds to the width of the solar panel (50), one heat collector (40) can be used. In the above one collector (40), a groove shape into which a positioning reference (O) can be inserted can be created in the cross section of the collector (40) to determine the position.

[0258] FIG. 25b is an enlarged cross-sectional view of an area (P3) of FIG. 24, in which two coupled collectors (40) (e.g., the first collector (41)) may be coupled by a coupling member (92). The positioning reference (O) may be positioned below the coupling member (92) with at least a portion thereof inserted into the short support (91). The collectors (40) may be coupled to each other as their first protruding portions (481) facing each other are fastened by a coupling member (92) such as a clamp. When the collectors (40) are arranged so that the coupling member (92) faces the positioning reference (O), the two coupled collectors (40) can be easily aligned on the short support (91).

[0259] Referring to Fig. 26, two combined collectors (40) (e.g., second collectors (42)) are additionally constructed in the structure disclosed in Fig. 25a, and the first collector (41) and the second collector (42) are arranged in parallel. For example, the solar module (30) can be manufactured in a structure in which four collectors (40) are connected in total by connecting the second collectors (42) to one side of the first collector (41) and the first collector (41).

[0260] Fig. 27a is an enlarged cross-sectional view of an area (P4) where the first heat collector (41) and the second heat collector (42) of Fig. 26 are coupled, and the first heat collector (41) and the second heat collector (42) are coupled by a coupling member (92), and a shortened support member (91) can be positioned below the coupling member (92). The first heat collector (41) and the second heat collector (42) can be connected to each other as the second protrusion portions (482) facing each other among the respective coupling protrusion portions are coupled by a coupling member (92) such as a clamp.

[0261] Fig. 27b is an enlarged cross-sectional view of one side area (P5) of the heat collector (40) of Fig. 26. Long-axis insulating members (94) can be placed on both outer sides of one heat collector (40) and joined with a joining member (92) such as a clamp. Accordingly, the joining member (92) and the long-axis insulating member (94) can be fixed on a short-axis support (91).

[0262] Referring to Fig. 28, an expansion frame (93) is coupled within a support portion expansion hole (490) to further expand the heat collector (40) in the longitudinal direction (e.g., in the length direction). The expansion frame (93) is in the form of an aluminum profile, and the heat collector (40) can be additionally connected by inserting the expansion frame (93) within the expansion hole (490) and fixing it with a connecting member such as a clamp. The expansion frame (93) can serve as a longitudinal support.

[0263] Referring to Fig. 29, a process for connecting a refrigerant supply pipe or a refrigerant outlet pipe to a connector (87) of a flow path (430) at one end of a heat collector (40) is illustrated. A pair of flow paths (430) may be formed for each heat collector (40), one flow path may be connected to the refrigerant supply pipe, and the other flow path may be connected to the refrigerant outlet pipe. Even when it is necessary to connect refrigerant flow paths between heat collectors (40), a connecting pipe such as a flexible pipe may be used for joining.

[0264] Afterwards, the installation of the piping and its associated thermal operating system can be completed and a functional test can be conducted. Additionally, electrical wiring for connection to the solar panel (50) can be installed utilizing the empty space in the collector (40).

[0265] Referring to Fig. 30, before arranging the solar panels (50) on the upper surface of the heat collector (40), a thermally conductive material (95) can be arranged on the upper surface of the heat collector (40). The thermally conductive material (95) can increase the thermal conductivity of the space between the upper surface of the heat collector (40) and the solar panels (50). For example, the thermally conductive material (95) can be arranged in the form of applying or attaching a thermal interface material (TIM) such as thermal grease to the upper surface of the heat collector (40). Fig. 30 illustrates a thermally conductive material (95) arranged on a portion of the upper surface of the first heat collector (41) corresponding to the size of one unit of solar panels (50). The thermally conductive material (95) can be arranged on the entire upper surface of the combined heat collectors (40).

[0266] Referring to Fig. 31, a process of arranging solar panels (50) on the upper surface of a heat collector (40) is illustrated. For example, one unit of solar panels (50) may be arranged across the upper surfaces of two first heat collectors (41) arranged in parallel.

[0267] Referring to FIG. 32, a process of arranging a plurality of solar panels (50) on the upper surface of a solar collector (40) is illustrated. For example, one solar panel (50) may be arranged across the upper surfaces of two solar collectors (40) arranged in parallel (e.g., a first solar collector (41)). For example, three solar panels (50) may be arranged in a row on the first solar collector (41), and three solar panels (50) may be arranged in a row on the second solar collectors (42).

[0268] FIG. 33a is an enlarged cross-sectional view of an area (P6) where the first heat collector (41) and the second heat collector (42) of FIG. 32 are coupled, wherein the first heat collector (41) and the second heat collector (42) are coupled by a part of a coupling member (92), and another part of the coupling member (92) can be coupled with a frame (51) of a solar panel (50). For example, a lower part of the coupling member (92) can couple the second protruding parts (482) that face each other, and an upper part of the coupling member (92) can couple the frames (51) that cover the solar panels (50) that face each other.

[0269] FIG. 33b is an enlarged cross-sectional view of one side region (P7) of the heat collector (40) of FIG. 33, and both outer sides of the heat collector (40) may be joined by a long-axis insulating member (94) and a part of a joining member (92). Another part of the joining member (92) may join the frame (51) of the solar panel (50) and the long-axis insulating member (94). For example, the lower part of the joining member (92) may join the first protruding part (481) of the heat collector (40) and the long-axis insulating member (94), and the upper part of the joining member (92) may join the frame (51) and the long-axis insulating member (94) that cover the solar panels (50) facing each other. Thereafter, an electrical function test related to the solar panel (50) may be performed.

[0270] Referring to FIG. 34, a sealing member (71) may be placed in the spaced apart spaces of the solar panels (50). The sealing member (71) may be placed along the short axis direction on the heat collector (40). For example, the sealing member (71) may seal the space between the solar panels A (50a) and B (50b), thereby limiting or reducing heat from being released from the heat collector (40) as air passes through the space. The sealing member (71) may seal the space between the solar panels A (50a) and B (50b), thereby limiting or reducing contaminants such as rainwater or dust from entering between the solar panels A (50a) and B (50b).

[0271] FIG. 35a is an enlarged cross-sectional view (P8) of a sealing member (71) disposed in a space between the heat collectors (40) of FIG. 34 (e.g., the first heat collector (41) and the second heat collector (42)), wherein the sealing member (71) can seal the space between the frame A (51a) of the solar panel A (50a) and the frame B (51b) of the solar panel B (50b). For example, the sealing member (71) may be disposed such that an upper portion covers a portion of the upper side of the frames A (51a) and B (51b) that face each other, and a lower portion penetrates the space between the frames A (51a) and B (51b). The sealing member (71) is formed of an elastic material, and can seal the space between the frames A (51a) and B (51b).

[0272] FIG. 35b is an enlarged cross-sectional view of one side area (P9) of the heat collector (40) of FIG. 34 (e.g., the first heat collector (41) or the second heat collector (42)), wherein the sealing members (71) arranged on both outer sides of the first heat collector (41) can seal the space between the long-axis insulation member (94) and the frame A (51a) of the solar panel A (50a). For example, the sealing member (71) may be arranged so that the upper portion covers a portion of the upper side of the frame A (51a) and the long-axis insulation member (94) facing each other, and the lower portion penetrates the space between the frame A (51a) and the long-axis insulation member (94). The sealing member (71) is formed of an elastic material, and can seal the space between the frame A (51a) and the long-axis insulation member (94).

[0273] In general, the current level of solar power generation technology is that only about 20% of the solar energy incident on a commercial photovoltaic (PV) panel is converted into electricity, about 10% is lost through reflection, etc., and the remaining about 70% of the energy is converted into heat, which can heat the solar panel.

[0274] A solar thermal module according to one embodiment of the present disclosure can generate and utilize not only electricity but also heat from sunlight by regenerating heat generated by solar panels. Accordingly, it can provide photovoltaic thermal (PVT) technology that increases the overall solar renewable energy efficiency (e.g., electricity + heat) to approximately 40% to 50% or more.

[0275] A solar module according to one embodiment of the present disclosure can arrange multiple solar panels in parallel on a single collector (e.g., manufactured and managed as an array unit). Accordingly, the solar module according to the present disclosure can provide a structure that is advantageous for piping work and maintenance compared to a typical structure (e.g., one panel is arranged on a single collector).

[0276] According to one embodiment of the present disclosure, a solar module can be manufactured as a heat collector device in which a heat collector plate, a coolant passage, and a support are integrally formed. Accordingly, the solar module of the present disclosure can provide a structure with improved thermal efficiency and maintenance compared to a typical structure (e.g., in which the heat collector plate, coolant passage, and support are manufactured separately and then combined).

[0277] A solar module according to one embodiment of the present disclosure can improve heat collection efficiency by manufacturing a heat collection device in which a heat collector, a coolant passage, and a support are integrally formed through an aluminum profile.

[0278] A solar module according to one embodiment of the present disclosure can provide material savings and simplified installation during construction, as compared to a typical structure (e.g., during construction, the short-axis support and the long-axis support are arranged separately and then the collector plate is arranged), by manufacturing a collector device including a long-axis support.

[0279] The solar thermal module collector according to one embodiment of the present disclosure can use commercially available solar panels, simplify manufacturing productivity, and reduce the number of man-hours required for construction, thereby reducing the cost of materials and manpower.

[0280] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure belongs from the description below.
