Description

Technology Field

[0001] The present invention relates to a cooling fan using a thermoelectric element with a high-efficiency cooling and heat dissipation contact structure, and more specifically, to a cooling fan using a thermoelectric element with a high-efficiency cooling and heat dissipation contact structure capable of electronically cooling internal air using heat absorption or heat generation while improving the flow contact structure with the air for each cooling or heat dissipation area to very efficiently output cold air. Background Technology

[0003] Generally, in hot weather such as summer, people create a cool indoor environment to cool down by using fans or air conditioners that can generate cool air. However, since air conditioners consume more power than fans, are not portable, and require the installation of an outdoor unit, households that use air conditioners also use household and portable fans.

[0005] However, in the case of electric fans, the principle is to generate wind by creating a pressure difference through the fan. While users can feel cool by lowering their body heat through this wind, there is a limit to the coolness because the wind itself does not contain cold air. In particular, being exposed to hot wind in hot weather is not a very refreshing experience.

[0007] Accordingly, fans capable of generating cooler air using refrigerants such as water or ice are being developed and released; however, since these refrigerant-equipped fans require the supply of water or ice after a certain period of time, they cause inconvenience to the user.

[0009] Meanwhile, with the development of Peltier elements, which generate cold and warm air through the Peltier effect, research on cooling or heating fans using Peltier elements, also known as thermoelectric elements, is actively underway. The Peltier effect refers to the phenomenon where, when an electric current is passed through an element made of two metals with different properties (P-type semiconductor and N-type semiconductor), heat is generated on one side and lost on the other at the junction of the two metals, resulting in simultaneous cooling and heating.

[0011] As prior art disclosed in relation to a cooling fan using a thermoelectric element as described above, Registered Patent Publication No. 2156987 (September 10, 2020) discloses a portable cooling fan capable of increasing energy efficiency and providing coolness and comfort to a user for a long time, comprising: a thermoelectric element module in which a heat-absorbing surface is formed on one side and a heat-generating surface is formed on the other side based on electronic cooling; a thermoelectric element housing portion that accommodates the thermoelectric element module inside; a first fan that blows cold air generated by the heat absorption of the heat absorption surface; a blower head formed with a blower opening for discharging the blown cold air; and a cold air transfer portion that connects the thermoelectric element housing portion and the blower head and performs heat exchange for the transfer of cold air or the generation of cold air from the heat absorption surface to the blower head, wherein the cooling fan is configured to include a heat absorption heat sink attached to the heat absorption surface and a heat generation heat sink attached to the heat-generating surface.

[0013] In addition, Registered Patent Publication No. 2206583 (January 18, 2021) describes a blower fan that rotates by a motor to generate wind; A refrigerant-free air cooler is known to be provided, comprising: a cooling module provided in front of the blower fan and cooling the wind to provide cold air to the outside; wherein the cooling module comprises a thermoelectric element, one side of which absorbs heat to form a low-temperature portion and the other side of which generates heat to form a high-temperature portion by means of a power source; a low-temperature heat transfer plate, which is formed in the shape of a plate and is provided in a direction intersecting the rotational axis direction of the blower fan, and one side of the thermoelectric element is connected to the rear side to receive cold air; and a water block provided to cover the other side of the thermoelectric element and through which cooling water flows, wherein the wind from the blower fan is cooled as it passes through the low-temperature heat transfer plate while the heat of the high-temperature portion is not released to the outside by the water block, and the low-temperature heat transfer plate is formed in a fan shape and a plurality of them are provided radially along the same axis to form a circle when viewed from the front, and the plurality of low-temperature heat transfer plates are provided such that they do not overlap each other or their edges appear to overlap when viewed from the front, and are provided such that they are spaced apart from each other along the axial direction when viewed from the side, thereby increasing the indoor cooling effect. there is.

[0015] However, all of the aforementioned conventional technologies had a problem in that the structure of the multiple cooling fins and heat dissipation fins installed for the purpose of cooling and heat dissipation from the thermoelectric element was simply extended in a straight line, resulting in reduced efficiency of contact with air and consequently a decrease in cooling and heat dissipation performance.

[0046] The present invention features a cooling fan utilizing a thermoelectric element with a high-efficiency cooling and heat dissipation contact structure, comprising: a main body case having an internal space formed with a cooling area and a heat dissipation area divided into left and right sides, and equipped with a cold air discharge port and an exhaust port; a thermoelectric element installed at the boundary between the cooling area and the heat dissipation area within the main body case, having a heating surface that generates heat by supplying current and a cooling surface that absorbs heat; a heat dissipation unit installed within the heat dissipation area of ​​the main body case, comprising a heat dissipation means that dissipates heat by insulatingly bonding to the heating surface of the thermoelectric element, and a heat dissipation driving fan installed corresponding to the lower side of the heat dissipation means and capable of blowing air toward the exhaust port; and a cooling unit installed within the cooling area of ​​the main body case, comprising a cooling means that dissipates cold air by insulatingly bonding to the cooling surface of the thermoelectric element, and a cooling driving fan installed corresponding to the upper side of the cooling means and capable of blowing air toward the cold air discharge port.

[0048] Next, a preferred embodiment of a cooling fan using a thermoelectric element with a high-efficiency cooling and heat dissipation contact structure according to the present invention will be described in detail with reference to the drawings.

[0050] First, an embodiment of a cooling fan using a thermoelectric element with a high-efficiency cooling and heat dissipation contact structure according to the present invention is formed by including a main body case (10), a thermoelectric element (20), a heat dissipation part (30), and a cooling part (40), as shown in FIGS. 1 and 2.

[0052] As shown in FIGS. 1 and 2, the main body case (10) is formed in a box shape that has an internal space formed so that the overall components of the present invention (thermoelectric element (20), heat dissipation part (30), cooling part (40), etc.) can be mounted inside.

[0054] The main body case (10) has a structure in which the internal space is divided into left and right sides, forming a cooling area (s1) and a heat dissipation area (s2). That is, the main body case (10) is configured with a partition member (15) that supports and fixes the thermoelectric element (20) while separating the cooling area (s1) and the heat dissipation area (s2). Accordingly, it is possible for the air in the cooling area (s1) and the air in the heat dissipation area (s2) within the main body case (10) to flow only for cooling or heat dissipation in a separated, sealed space.

[0056] The above main body case (10) is configured to have a cold air discharge port (11) configured to discharge cold air to the outside corresponding to the cooling area (s1), and an exhaust port (13) configured to discharge heat to the outside corresponding to the heat dissipation area (s2).

[0058] In the above, the cold air discharge port (11) is in the shape of a funnel, and since the side of the main body case (10) is wide and gradually narrows toward the outside, it is possible to strongly guide the discharge of cold air.

[0060] As shown in FIGS. 1 and 2, the thermoelectric element (20) is formed in the shape of a thin plate and is installed at the boundary between the cooling area (s1) and the heat dissipation area (s2) inside the main body case (10).

[0062] The above thermoelectric element (20) is a structure capable of generating heat and cooling by supplying current, and is made of a semiconductor structure having a structure in which two different types of metals are joined.

[0064] The thermoelectric element (20) is supplied with current (DC current) from the outside, and when the current flows, a heating surface that generates heat on one side and a cooling surface that absorbs heat are formed on the opposite side of the heating surface. That is, the thermoelectric element (20) is installed in a structure in which the cooling surface is positioned toward the cooling area (s1) and the heating surface is positioned toward the heat dissipation area (s2).

[0066] The thermoelectric element (20) described above utilizes the Peltier effect, which is a phenomenon of the relationship between heat and electricity, and is configured to apply the phenomenon in which, when current is passed through two different metal junctions, one side generates heat and the other side absorbs heat depending on the direction of the current.

[0068] As shown in FIGS. 1 and 2, the heat dissipation unit (30) is installed in the heat dissipation area (s2) of the main body case (10) and performs the function of dissipating heat generated from the thermoelectric element (20).

[0070] As shown in FIG. 3, the heat dissipation unit (30) comprises a heat dissipation means (31) that dissipates heat by insulating and bonding to the heat-generating surface of the thermoelectric element (20), and a heat dissipation driving fan (37) that is installed corresponding to the lower side of the heat dissipation means (31) and can blow air toward the exhaust port (13).

[0072] The above heat dissipation means (31) is composed of a metal material with excellent thermal conductivity so that heat generated on the heat-generating surface of the thermoelectric element (20) can be efficiently transferred overall.

[0074] As shown in FIGS. 2 and 3, the heat dissipation means (31) comprises a heating plate (32) formed by insulatingly bonding to the heating surface of the thermoelectric element (20) and extending in the front-rear longitudinal direction, a plurality of heat dissipation fins (33) installed on the heating plate (32), and a heat dissipation connection plate (34) that integrally connects the ends of the plurality of heat dissipation fins (33).

[0076] The heat dissipation fins (33) are formed integrally on the heating plate (32) and installed to have a structure that extends outward. That is, the heat dissipation fins (33) are formed so that heat transferred to the heating plate (32) can move along a plurality of extended paths toward the outside.

[0078] A plurality of the above-mentioned heat dissipation fins (33) are arranged at intervals along the longitudinal direction of the heating plate (32) to form a flow path through which air can move, thereby enabling heat transfer through continuous contact with air.

[0080] At this time, since a plurality of holes (h1) are formed penetrating in a plurality of array directions in the heat dissipation fin (33), it is also possible to configure it so that the fluidity in the air flow path that can contact the heat dissipation fin (33) is increased, thereby improving the air contact efficiency.

[0082] As shown in FIG. 4, the heat dissipation fin (33) is configured to have a convex and concave sawtooth cross-sectional shape in the vertical direction, which is the air flow path corresponding to the heat dissipation drive fan (37). That is, since the air flow path for heat dissipation is formed between a plurality of the heat dissipation fins (33) and is configured to be curved in a zigzag pattern, it is possible to further enhance the contact efficiency between the air and the heat dissipation fin (33).

[0084] In addition, as shown in FIG. 5, the heat dissipation means (31) may also be configured to include a heat dissipation fin plate (39) that can form a zigzag path for air flow in the longitudinal direction of the heat dissipation fin (33) extended from the heating plate (32).

[0086] The above heat dissipation fin plate (39) is configured to be installed in an orthogonal direction corresponding to a plurality of heat dissipation fins (33). That is, it is formed to extend in a left-right horizontal direction corresponding to the heat dissipation fins (33) that are formed to extend in an up-and-down vertical direction, and is installed to be joined together corresponding to a plurality of heat dissipation fins (33), so that air can come into contact with the air flow path for heat dissipation of the heat dissipation fins (33).

[0088] The above heat dissipation fin plate (39) is arranged in a zigzag pattern with vertical spacing on the heat dissipation fin (33), thereby creating a curved air flow path. That is, by configuring the above heat dissipation fin plate (39), it is possible to further enhance the contact efficiency of the air within the heat dissipation means (31) as the air flow path curves in a zigzag pattern.

[0090] The heat dissipation connection plate (34) is installed on the heat dissipation fin (33) in parallel with the heating plate (32), and is installed to connect the ends of a plurality of heat dissipation fins (33) arranged at intervals on the heating plate (32), thereby integrating the heat dissipation fins (33) and closing one side of the heat dissipation fins (33), thereby minimizing the phenomenon of air escaping from the flow path.

[0092] Additionally, it is possible to configure a heat dissipation pin locking member (35) in the heat dissipation means (31) that is formed to extend through the path where the heat dissipation fins (33) are arranged and is connected to fix a plurality of the heat dissipation fins (33) as a single unit.

[0094] The above heat dissipation fin locking member (35) has a circular cross-section to facilitate air movement upon contact with air, and is composed of a metal material with excellent thermal conductivity, similar to the heat dissipation means (31), so it is possible to reinforce the heat dissipation function through heat transfer from the heat dissipation fin (33).

[0096] As shown in FIGS. 1 and 2, the cooling unit (40) is configured to be symmetrically positioned in the heat dissipation unit (30) with respect to the thermoelectric element (20), is installed in the cooling area (s1) of the main body case (10), and performs the function of dissipating cold air generated from the thermoelectric element (20).

[0098] As shown in FIG. 6, the above cooling unit (40) comprises a cooling means (41) that insulates and adheres to the cooling surface of the thermoelectric element (20) to radiate cold air, and a cooling drive fan (47) that is installed above the cooling means (41) and can blow air toward the cold air discharge port (11).

[0100] The above cooling means (41) is also constructed using a metal material with excellent thermal conductivity so that heat generated on the cooling surface of the thermoelectric element (20) can be efficiently transferred, just like the above heat dissipation means (31).

[0102] As shown in FIGS. 2 and 6, the above cooling means (41) comprises an absorption plate (42) formed by insulatingly bonding to the cooling surface of the thermoelectric element (20) and extending in the front-rear longitudinal direction, a plurality of cooling fins (43) installed on the absorption plate (42), and a cooling connection plate (44) that integrally connects the ends of the plurality of cooling fins (43).

[0104] The cooling fins (43) are formed integrally on the heat absorption plate (42) and installed to have a structure that extends outward. That is, the cooling fins (43) are formed so that the cold air transferred to the heat absorption plate (42) can move along a plurality of extended paths toward the outside.

[0106] A plurality of the above cooling fins (43) are arranged at intervals along the longitudinal direction of the heat absorption plate (42) to form a flow path through which air can move, thereby enabling efficient delivery of cold air to the air through continuous contact with the air.

[0108] At this time, the cooling fin (43) is configured to have a plurality of holes (h2) formed through it in a plurality of arrangement directions, similar to the heat dissipation fin (33), so that the fluidity in the air flow path that can contact the cooling fin (43) is increased, thereby improving the air contact efficiency.

[0110] As shown in FIG. 7, the cooling fin (43) is configured to have a convex and concave sawtooth cross-sectional shape in the vertical direction, which is the air flow path corresponding to the cooling drive fan (47). That is, since the air flow path for cooling is formed between a plurality of the cooling fins (43) and is configured to be curved in a zigzag pattern, it is possible to further enhance the contact efficiency between the air and the cooling fin (43).

[0112] In addition, the cooling means (41) may also be configured to include a cooling fin plate (49) that can form a zigzag path for air flow in the longitudinal direction of the cooling fin (43) extended from the cooling plate (32), as shown in FIG. 8.

[0114] The above cooling fin plate (49) is configured to be installed in an orthogonal direction corresponding to a plurality of cooling fins (43). That is, it is formed to extend horizontally to the left and right corresponding to the cooling fins (43) that are formed to extend vertically upward and downward, and is installed to be joined together corresponding to a plurality of cooling fins (43), so that air can come into contact with the air flow path for heat dissipation of the cooling fins (43).

[0116] The above cooling fin plate (49) is arranged in a zigzag pattern with vertical spacing on the cooling fin (43), thereby creating a curved airflow path. That is, by configuring the cooling fin plate (49), it is possible to further enhance the contact efficiency of the air within the cooling means (41) as the airflow path curves in a zigzag pattern.

[0118] The cooling connection plate (44) is installed on the cooling fin (43) in parallel with the heat absorption plate (42), and is installed to connect the ends of a plurality of cooling fins (43) spaced apart from each other on the heat absorption plate (42), thereby integrating the cooling fins (43) and closing one side of the cooling fins (43), so that the phenomenon of air escaping from the flow path is minimized.

[0120] Additionally, it is possible to configure a cooling pin locking member (45) in the cooling means (41) that is formed to extend through the path where the cooling fins (43) are arranged and connects a plurality of the cooling fins (43) to fix them integrally.

[0122] In the above, the cooling fin locking member (45) forms a circular cross-section to facilitate smooth movement in contact with air, and is composed of a metal material with excellent thermal conductivity, similar to the cooling means (41), so it is possible to reinforce the cooling function through the transfer of cold air from the cooling fin (43).

[0124] In other words, according to the air cooler utilizing a thermoelectric element with a high-efficiency cooling and heat dissipation contact structure configured as described above, heat dissipation and cooling are performed while separating the heat dissipation section and the cooling section based on the thermoelectric element inside. This configuration allows for the continuous maintenance of product functionality while extending product lifespan and improving product cooling performance through excellent cooling and heat dissipation efficiency in each area.

[0126] Furthermore, since the present invention configures the airflow paths of each region to be curved in a zigzag pattern by means of heat dissipation fins and cooling fins, it is possible to further improve the cooling and heat dissipation performance of the product by maximizing air contact efficiency.

[0128] Although a preferred embodiment of a cooling fan using a thermoelectric element with a high-efficiency cooling and heat dissipation contact structure according to the present invention has been described above, the present invention is not limited thereto and can be implemented with various modifications within the scope of the claims, the specification of the invention, and the attached drawings, and such modifications also fall within the scope of the present invention.
