For example, the first part (151a), the second part (151b), and the first wall (15a) may be formed as one body.

The first part (151a) can define an outer surface (i.e., top surface) of the upper part (151) and can be adjacent to or in contact with an inner surface (i.e., bottom surface) of the top (13). For example, the first part (151a) can be attached to or coupled to the lower surface of the top (13). The second part (151b) can be opposite the first part (151a) with respect to the first flow path (15P1) and can define an inner surface (i.e., bottom surface) of the upper part (151). The second part (151b) can be parallel to the first part (151a). The first wall (15a) can intersect or be perpendicular to the first part (151a) and the second part (151b), and can connect one end of the first part (151a) and one end of the second part (151b). The first month (15a) can define one end of the upper part (151), i.e., one end of the jacket (15). Accordingly, the boundary of the first euro (15P1) can be defined by the inner surface of the first part (151a), the inner surface of the second part (151b), and the inner surface of the first month (15a).

The second flow path (15P2) may be formed inside the lower part (152). The second flow path (15P2) may be an internal space of the lower part (152). The second flow path (15P2) may have a size corresponding to the lower part (152). The lower part (152) may include a first part (152a), a second part (152b), and a second wall (15b). For example, the first part (152a), the second part (152b), and the second wall (15b) may be formed as one body.

The first part (152a) can define an outer surface (i.e., a lower surface) of the lower part (152). The first part (152a) can be spaced upward from the plate (14). The second part (152b) can be opposite the first part (152a) with respect to the second flow path (15P2) and can define an inner surface (i.e., a top surface) of the lower part (152). The second part (152b) can be adjacent to or in contact with the lower surface of the substrate (16). For example, the second part (152b) can be attached to or coupled to the lower surface of the substrate (16). The second part (152b) can be parallel to the first part (152a). The second wall (15b) may intersect or be perpendicular to the first part (152a) and the second part (152b), and may connect one end of the first part (152a) and one end of the second part (152b). The second wall (15b) may define one end of the first lower part (152), i.e., the other end of the jacket (15). Accordingly, the boundary of the second flow path (15P2) may be defined by the inner surface of the first part (152a), the inner surface of the second part (152b), and the inner surface of the second wall (15b).

The third flow path (15P3) may be formed inside the side part (153). The third flow path (15P3) may be an internal space of the side part (153). The third flow path (15P3) may have a size corresponding to the side part (153). The side part (153) may include a first part (153a) and a second part (153b).

The first part (153a) can define the outer surface of the side part (153). One end of the first part (153a) can be connected or coupled to the first part (151a) of the upper part (151), and the other end of the first part (153a) can be connected or coupled to the first part (152a) of the lower part (152). For example, the first part (153a), the first part (151a), and the first part (152a) can be formed as one body. The second part (153b) can be opposite the first part (153a) with respect to the third flow path (15P3) and can define the inner surface of the side part (153). The second part (153b) can be adjacent to or in contact with the side surface of the substrate (16). One end of the second part (153b) may be connected or coupled to the second part (151b) of the upper part (151), and the other end of the second part (153b) may be connected or coupled to the second part (152b) of the lower part (152). For example, the second part (153b), the second part (151b), and the second part (152b) may be formed as one body. The second part (153b) may be parallel to the first part (153a). Accordingly, the boundary of the third flow path (15P3) may be defined by the inner surface of the first part (153a) and the inner surface of the second part (153b).

The first to third flow paths (15P1, 15P2, 15P3) may be interconnected. The first flow path (15P1) may be interconnected with the second flow path (15P2) via the third flow path (15P3). For example, a wick structure may be provided on the inside of the jacket (15) to facilitate the movement of water in the first to third flow paths (15P1, 15P2, 15P3) described below.

The top (13) may face the outside of the base (10, see FIG. 1), and a temperature difference may occur between the inside and outside of the top (13). For example, the temperature outside the top (13) may be lower than the temperature inside the top (13). In this case, moisture in the air in the first flow path (15P1) may condense and form dew on the inside of the upper part (151). At least a portion of the liquid water in the first flow path (15P1) may flow to the second flow path (15P3) and the third flow path (15P2) (see A1, A2, and A3 in FIG. 12). The liquid water in the third flow path (15P3) may be evaporated by the heat of the element (16M) mounted on the substrate (16). This evaporation may be concentrated in a portion of the third flow path (15P3) corresponding to the area where the element (16M) of the substrate (16) is mounted.

Accordingly, the first flow path (15P1) can form an air insulation layer, and can minimize dew formation on the inner surface of the upper part (151), i.e., the lower surface of the second part (151b), and the inflow of such dew into the substrate (16). In addition, the substrate (16) and the element (16M) mounted thereon can be cooled by the evaporation of water in the third flow path (15P3) described above, and in this respect, the jacket (15) can be considered to function as a heat pipe.

A heat sink (17) may be adjacent to the element (16M) and may be positioned between the substrate (16) and the upper part (151). One end (17a) of the heat sink (17) may be adjacent to or in contact with the lower surface of the upper part (151). The other end (17b) of the heat sink (17) may be positioned in a high temperature section of the substrate (16). The other end (17b) of the heat sink (17) may be in contact with the substrate (16). The other end (17b) of the heat sink (17) may be in contact with the element (16M). For example, the heat sink (17) may be a member made of a material with excellent thermal conductivity, such as metal. As another example, the heat sink (17) may be a heat pipe filled with a refrigerant (e.g., water) therein. The refrigerant of the heat sink (17) can be vaporized by the heat of the element (16M) at the other end (17b) of the heat sink (17) and can be liquefied at one end (17a) of the heat sink (17).

Accordingly, the heat of the substrate (16) and the element (16M) can be transferred to the upper part (151) by heat conduction and/or heat convection of the heat sink (17). In addition, the temperature of the inner surface of the upper part (151), i.e., the lower surface of the second part (151b), can be increased by the heat transferred by the heat sink (17). In other words, the heat sink (17) can minimize dew formation on the lower surface of the second part (151b) and the inflow of such dew into the substrate (16), and can prevent damage to the circuit and element (16M) of the substrate (16) and/or corrosion or damage to the substrate (16) or adjacent components due to the dew.

Referring to FIG. 13, a first flow path (15P1') may be formed between the upper part (151') and the top (13). The first flow path (15P1') may be a space between the upper part (151') and the top (13). The upper part (151') may have a plate shape and may be opposite the top (13) with respect to the first flow path (15P1'). The first wall (15a') may define one end of the upper part (151'), that is, one end of the jacket (15'), and may be in contact with the lower surface of the top (13). For example, the first wall (15a') may be attached to, joined to, or formed on the lower surface of the top (13). Accordingly, the boundary of the first euro (15P1') can be defined by the inner surface of the top (13), the inner surface of the upper part (151'), and the inner surface of the first month (15a').

One end of the first part (153a) of the side part (153) can be in contact with the lower surface of the top (13). For example, the one end of the first part (153a) can be attached to, coupled to, or formed on the lower surface of the top (13). The other end of the first part (153a) of the side part (153) can be connected to or coupled to the first part (152a) of the lower part (152). One end of the second part (153b) of the side part (153) can be connected to or coupled to the upper part (151'). The other end of the second part (153b) of the side part (153) can be connected to or coupled to the second part (152b) of the lower part (152).

The first to third euros (15P1', 15P2, 15P3) can be connected to each other. The first euro (15P1') can be connected to the second euro (15P2) via the third euro (15P3).

The tower (13) may face the outside of the base (10, see FIG. 1), and a temperature difference may occur between the inside and outside of the tower (13). For example, the temperature outside the tower (13) may be lower than the temperature inside the tower (13). In this case, moisture in the air in the first flow path (15P1') may condense and form dew on the inside of the tower (13). At least a portion of the liquid water in the first flow path (15P1') may flow to the second flow path (15P3) and the third flow path (15P2) (see A1, A2, and A3 in FIG. 13). The liquid water in the third flow path (15P3) may be evaporated by the heat of the element (16M) mounted on the substrate (16). This evaporation may be concentrated in a portion of the third flow path (15P3) corresponding to the area where the element (16M) of the substrate (16) is mounted.

Accordingly, the first flow path (15P1') can form an air insulation layer, and can minimize dew formation on the inner surface of the upper part (151') and the inflow of such dew into the substrate (16). In addition, the substrate (16) and the element (16M) mounted thereon can be cooled by the evaporation of water in the third flow path (15P3) described above, and in this respect, the jacket (15') can be considered to function as a heat pipe.

A heat sink (17) may be adjacent to the element (16M) and may be positioned between the substrate (16) and the upper part (151'). One end (17a) of the heat sink (17) may be adjacent to or in contact with the lower surface of the upper part (151'). The other end (17b) of the heat sink (17) may be positioned in a high temperature section of the substrate (16). The other end (17b) of the heat sink (17) may be in contact with the substrate (16). The other end (17b) of the heat sink (17) may be in contact with the element (16M). For example, the heat sink (17) may be a member made of a material with excellent thermal conductivity. For example, the heat sink (17) may be a heat pipe filled with a refrigerant (e.g., water) therein. The refrigerant of the heat sink (17) can be evaporated by the heat of the element (16M) at the other end (17b) of the heat sink (17) and can be liquefied at one end (17a) of the heat sink (17).

Accordingly, the heat of the substrate (16) and the element (16M) can be transferred to the upper part (151') by heat conduction and/or heat convection of the heat sink (17). In addition, the temperature of the lower surface, which is the inner surface of the upper part (151'), can be increased by the heat transferred by the heat sink (17). In other words, the heat sink (17) can minimize dew formation on the lower surface of the upper part (151') and the inflow of such dew into the substrate (16), and can prevent damage to the circuit and element (16M) of the substrate (16) and/or corrosion or damage to the substrate (16) or adjacent components due to the dew.
