Description

Water jacket structure and cooling device for cooling water including the same

[0001] The present invention relates to a water jacket structure and a cooling device for cooling water including the same, and more specifically, to a water jacket structure in which a hot passage part for recovering heated cooling water used for cooling within a device into a tank and a cooling passage part for cooling cooling water stored within a tank and supplying it into a device are integrated, and a cooling device for cooling water including the same.

[0002] As interest in skin care has been increasing day by day, various skin care devices are being developed.

[0003] Devices for skin care are proposed in various structures, such as skin treatment devices using ultrasound, skin treatment devices using laser, skin treatment devices using RF energy, skin cleansing devices for face lifting or skin tightening treatments, and cooling fat dissolving treatment devices.

[0004] A device for skin care using ultrasound uses a handpiece for generating ultrasound to generate heat from high-intensity focused ultrasound waves in skin tissue at a certain depth from the skin surface, thereby inducing degeneration and regeneration of skin tissue, thereby producing skin beauty effects such as wrinkle improvement or cosmetic surgery.

[0005] In addition, a skin treatment device using a laser uses a handpiece for generating a laser to irradiate the skin with a laser of a certain size as a point, and only applies heat with the laser to the target area to damage the skin tissue, treating the patient's skin. It is used for various purposes such as preventing hair loss, promoting hair growth, peeling, skin regeneration, whitening, removing wrinkles or spots, and removing freckles.

[0006] In addition, a skin treatment device using RF energy is performed by applying electric power to the RF electrode while the RF electrode is in close contact with the skin using a handpiece equipped with an RF electrode to deliver RF energy to the patient's skin, and is used in various ways, such as skin remodeling / resurfacing through contraction or wound healing response of collagen in the lower dermis, wrinkle removal, and treatment of sebaceous glands, hair follicles, fatty tissue, and spider veins.

[0007] In addition, the skin cleansing device treats the patient's skin by discharging a cleansing solution to the skin surface through a skin cleansing handpiece to penetrate functional cosmetic ingredients into the skin and polishing the skin surface.

[0008] Devices for skin care using ultrasound, devices for skin treatment using laser, and devices for skin treatment using RF energy are equipped with a cooling device including a chiller or radiator that circulates cooling water into the handpiece to cool the skin during treatment.

[0009] Conventional cooling devices have a structure in which heated cooling water is recovered into a cooling water tank through a recovery line used in a device such as a handpiece, and then the cooling water in the cooling water tank is cooled and supplied to a device such as a handpiece through a supply line using a cooler such as a chiller or radiator.

[0010] However, conventional cooling devices have problems in that the cooling efficiency is low and it is difficult to make the size smaller because the return line that returns the heated cooling water used in the device such as a handpiece into a cooling water tank and the supply line that cools the cooling water in the cooling water tank and supplies it to the device such as a handpiece are located separately.

[0011] A prior patent related to the present invention is Korean Patent Registration No. 1307551, “Handpiece of ultrasonic device” (registered on September 5, 2013).

[0012] The purpose of the present invention is to provide a water jacket structure and a cooling device for cooling water including the same, which can increase cooling efficiency and reduce the size of the cooling device by integrating a hot path section for recovering heated cooling water used for cooling within a device into a tank and a cooling path section for cooling the cooling water stored within the tank and supplying it into the device.

[0013] In order to achieve the above-described object of the present invention, one embodiment of a water jacket structure according to the present invention is characterized by including a water jacket housing part having a hot flow path part through which cooling water used for cooling passes within a device and a cooling flow path part through which cooling water supplied to the device passes, and a flow path separation insulation part provided within the water jacket housing part and positioned between the hot flow path part and the cooling flow path part to block heat exchange.

[0014] One embodiment of a cooling device for cooling water according to the present invention includes a cooling water storage tank for storing cooling water supplied to a device, a cooling jacket part connected to the cooling water storage tank and receiving and cooling the cooling water stored in the cooling water storage tank, a cooling device for cooling the cooling water passing through the inside of the cooling jacket part, a first cooling water circulation line part connecting the device and the cooling jacket part, a second cooling water circulation line part connecting the cooling jacket part and the cooling water storage tank, and a cooling water pump for circulating the cooling water through the first cooling water circulation line part and the second cooling water circulation line part, wherein the cooling jacket part includes a water jacket housing part having a hot passage part through which cooling water used for cooling in the device passes and a cooling passage part through which cooling water supplied to the device passes, and a passage separation insulation part provided in the water jacket housing part and positioned between the hot passage part and the cooling passage part to block heat exchange.

[0015] In the present invention, the water jacket housing part is provided with a first inlet located at one end of the hot channel part for introducing cooling water into the hot channel part, a first outlet located at the other end of the hot channel part for discharging cooling water inside the hot channel part, a second inlet located at one end of the cooling channel part for introducing cooling water into the cooling channel part, and a second outlet located at the other end of the cooling channel part for discharging cooling water inside the cooling channel part, and the first inlet and the second outlet may be located on one side of the water jacket housing part, and the second inlet and the first outlet may be located on the other side of the water jacket housing part opposite the one side.

[0016] In the present invention, the hot flow path part may be formed as a straight flow path inside the water jacket housing part, and the cooling flow path part may be formed as a zigzag flow path.

[0017] In the present invention, an insulating partition wall is provided inside the water jacket housing to separate the hot flow path section and the cooling flow path section, and the insulating partition wall for dividing the flow path section is inserted into the insulating partition wall to block heat exchange between the hot flow path section and the cooling flow path section.

[0018] In the present invention, the first cooling water circulation line section may include a first jacket inlet line section connecting the user device and the hot flow path section to introduce cooling water heated in the user device into the hot flow path section, and a cooling water supply line section connecting the user device and the cooling flow path section to supply cooling water cooled in the cooling flow path section into the user device, and the second cooling water circulation line section may include a jacket discharge line section connecting the hot flow path section and the cooling water storage tank to introduce cooling water passing through the hot flow path section into the cooling water storage tank, and a second jacket inlet line section connecting the cooling flow path section and the cooling water storage tank to introduce cooling water in the cooling water storage tank into the cooling flow path section.

[0019] In the present invention, the cooling device may include a thermoelectric element part having a heat absorption surface mounted on one surface of the water jacket housing part, and a heat sink part mounted on a heat dissipation surface of the thermoelectric element part.

[0020] In the present invention, the cooling device may further include a cooling fan unit that is mounted on the heat sink unit and circulates air by rotating the fan.

[0021] The present invention has the effect of increasing cooling efficiency and minimizing the size of the cooling device by integrating a hot path section that recovers heated cooling water used for cooling within a device into a tank and a cooling path section that cools the cooling water stored within the tank and supplies it to the device.

[0022] In addition, the present invention is particularly applicable to various skin treatment devices, and has the effect of miniaturizing the main body size and reducing manufacturing costs, thereby greatly improving marketability.

[0043] In addition, when describing the present invention below, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

[0044] FIG. 1 is a cross-sectional view illustrating one embodiment of a water jacket structure according to the present invention, and illustrates the internal structure of the water jacket structure according to the present invention.

[0045] Referring to FIG. 1, one embodiment of a water jacket structure according to the present invention is described in detail below.

[0046] One embodiment of a water jacket structure according to the present invention includes a water jacket housing portion (10) having a plurality of flow paths formed therein through which cooling water can pass.

[0047] The water jacket housing part (10) is provided with a space for forming a plurality of flow paths through which cooling water can pass inside, and the plurality of flow paths include a hot flow path part (11) through which cooling water used for cooling in the device passes and a cooling flow path part (12) through which cooling water supplied to the device passes.

[0048] In addition, the water jacket housing part (10) is provided with a first inlet (10a) and a first outlet (10b) of the hot flow path part (11), and a second inlet (10c) and a second outlet (10d) of the cooling flow path part (12).

[0049] The first inlet (10a) is located at one end of the hot flow path (11) and is a passage for introducing cooling water into the interior of the hot flow path (11), and the first outlet (10b) is located at the other end of the hot flow path (11) and is a passage for introducing cooling water into the interior of the hot flow path (11).

[0050] In addition, the second inlet (10c) is located at one end of the cooling passage section (12) and is a passage for introducing cooling water into the interior of the cooling passage section (12), and the second outlet (10d) is located at the other end of the cooling passage section (12) and is a passage for introducing cooling water into the interior of the cooling passage section (12).

[0051] In more detail, the water jacket housing part (10) is provided with a first inlet (10a) located at one end of the hot passage part (11) for introducing cooling water into the interior of the hot passage part (11), a first outlet (10b) located at the other end of the hot passage part (11) for discharging cooling water inside the hot passage part (11), a second inlet (10c) located at one end of the cooling passage part (12) for introducing cooling water into the interior of the cooling passage part (12), and a second outlet (10d) located at the other end of the cooling passage part (12) for discharging cooling water inside the cooling passage part (12).

[0052] The hot euro section (11) is connected to the device through the first inlet (10a), and the heated cooling water used for cooling in the device flows into the inside, and is connected to the cooling water storage tank (100) through the first outlet (10b).

[0053] In addition, the cooling duct (12) is connected to the cooling water storage tank (100) through the second inlet (10c) and is connected to the device through the second outlet (10d) to supply the cooled cooling water back into the device.

[0054] And, the first inlet (10a) and the first outlet (10b) are formed on opposite surfaces of the water jacket housing (10), and the second inlet (10c) and the second outlet (10d) are formed on opposite surfaces of the water jacket housing (10).

[0055] In addition, as an example, the first inlet (10a) and the second outlet (10d) are positioned on the same side of the water jacket housing (10), and the second inlet (10c) and the first outlet (10b) are positioned on the same side of the water jacket housing (10).

[0056] In more detail, the first inlet (10a) and the second outlet (10d) are located on one side of the water jacket housing (10), and the second inlet (10c) and the first outlet (10b) are located on the other side of the water jacket housing (10) opposite to the one side, so that the connection structure of the cooling water circulation line connected to the device and the cooling water storage tank (100) can be simplified according to the flow direction of the cooling water, and thus a compact design of the entire cooling device is possible.

[0057] Between the hot flow path (11) and the cooling flow path (12), an insulation part (20) is positioned to separate the flow paths and block heat exchange between the flow paths.

[0058] The insulation section (20) for dividing the euro is manufactured from a known insulation material that blocks heat exchange and is erected in the form of a partition wall to divide the hot euro section (11) and the cooling euro section (12).

[0059] The insulation section (20) for the euro section blocks the heat of the hot euro section (11) from being transferred to the cooling euro section (12), thereby preventing the heat of the hot euro section (11) from being transferred to the cooling euro section (12), thereby preventing the cooling efficiency of the coolant cooled in the cooling euro section (12) from being reduced, and can maintain the cooling efficiency of the coolant cooled in the cooling euro section (12) at a constant level.

[0060] In addition, as an example, the hot flow path (11) is formed as a straight flow path inside the water jacket housing (10), and the cooling flow path (12) is formed as a zigzag flow path.

[0061] The cooling path section (12) is formed in a zigzag shape to maximize the length of the path within a limited space, thereby satisfying a sufficient path length required for heat exchange when cooling the cooling water through heat exchange with the cooling device (300) described later, and increasing the cooling efficiency.

[0062] The water jacket housing part (10) is mounted on a cooling device (300) to be described later and is manufactured from a material with high thermal conductivity, such as copper, aluminum, or an alloy material containing copper or aluminum, to efficiently cool the cooling water passing through the internal hot flow path part (11) and the cooling flow path part (12) through heat exchange.

[0063] The water jacket housing (10) is manufactured using a material with high thermal conductivity, such as copper or aluminum, as an example, and can be manufactured using a known material with higher thermal conductivity than copper or aluminum, so a more detailed description is omitted.

[0064] Inside the water jacket housing (10), an insulating partition (13) is provided to separate the hot flow path (11) and the cooling flow path (12), and an insulating partition (20) for dividing the flow paths is inserted into the insulating partition (13) to block heat exchange between the hot flow path (11) and the cooling flow path (12).

[0065] The insulating bulkhead (13) forms one side of the hot flow path (11) or the cooling flow path (12), and is manufactured integrally with the water jacket housing (10) from a material with high thermal conductivity, such as copper or aluminum, so that when cooling water in the hot flow path (11) or the cooling flow path (12) is cooled through a cooling device (300) to be described later, the cooling efficiency is not reduced.

[0066]

[0067] Meanwhile, FIG. 2 is a perspective view illustrating one embodiment of a cooling device for cooling water according to the present invention, and FIG. 3 is a schematic diagram illustrating one embodiment of a cooling device for cooling water according to the present invention.

[0068] Referring to FIGS. 1 to 3, one embodiment of a cooling device for cooling water according to the present invention is described in detail below.

[0069] One embodiment of a cooling device for cooling water according to the present invention includes a cooling water storage tank (100) that stores cooling water supplied to a device, a cooling jacket unit (200) that is connected to the cooling water storage tank (100) and receives and cools the cooling water stored in the cooling water storage tank (100), a cooling device (300) that cools the cooling water passing through the interior of the cooling jacket unit (200), a first cooling water circulation line unit (400) that connects the device and the cooling jacket unit (200), a second cooling water circulation line unit (500) that connects the cooling jacket unit (200) and the cooling water storage tank (100), and a cooling water pump (600) that circulates the cooling water through the first cooling water circulation line unit (400) and the second cooling water circulation line unit (500).

[0070] The coolant in the coolant storage tank (100) circulates through the device, the coolant jacket, and the coolant storage tank (100) through the first coolant circulation line section (400) and the second coolant circulation line section (500) by the operation of the coolant pump (600), thereby cooling the heat generated during the operation of the device.

[0071] As an example, the device used is a handpiece (1) that the practitioner holds by hand and performs the treatment in a skin care device using ultrasound, a skin treatment device using laser, a skin treatment device using RF energy, etc., and as an example, the cooling device for cooling water according to the present invention is installed in a control body (2) that controls the operation of the handpiece (1) in a skin care device using ultrasound, a skin treatment device using laser, a skin treatment device using RF energy, etc.

[0072] The first cooling water circulation line (400) is included in the control cable (2a) connecting the control body (2) and the handpiece (1), supplies cooling water cooled in the cooling jacket (200) into the handpiece (1), and recovers the cooling water heated after being supplied into the handpiece and used for cooling into the cooling jacket (200).

[0073] The first coolant circulation line section (400) and the second coolant circulation line section (500) can be implemented in various modified forms with known structures such as pipes or hoses, etc., in which a flow path for coolant to flow is formed.

[0074] And, the cooling jacket part (200) includes an embodiment of the water jacket structure according to the present invention, which is the cooling device (300) described above.

[0075] That is, the first cooling water circulation line section (400) includes a first jacket inlet line section (410) that connects the user device and the hot passage section (11) and introduces cooling water heated in the user device into the hot passage section (11), a cooling water supply line section (420) that connects the user device and the cooling passage section (12) and supplies cooling water cooled in the cooling passage section (12) into the user device, and the second cooling water circulation line section (500) includes a jacket discharge line section (510) that connects the hot passage section (11) and the cooling water storage tank (100) and introduces cooling water that has passed through the hot passage section (11) into the cooling water storage tank (100), and a second jacket inlet line section (520) that connects the cooling passage section (12) and the cooling water storage tank (100) and introduces cooling water in the cooling water storage tank (100) into the cooling passage section (12).

[0076] The first jacket inlet line section (410) is connected to the first inlet port (10a) and introduces the coolant heated in the device into the hot flow section (11), and the jacket discharge line section (510) is connected to the first discharge port (10b) and supplies the coolant in the water jacket housing section (10), i.e., the coolant that has passed through the hot flow section (11), to the coolant storage tank (100).

[0077] In addition, the second jacket inlet line section (520) is connected to the second inlet (10c) to introduce cooling water in the cooling storage tank into the cooling passage section (12), and the cooling water supply line section (420) is connected to the second outlet (10d) to supply cooling water in the water jacket housing section (10), i.e., cooling water that has passed through the cooling passage section (12), to the user device.

[0078] The cooling jacket section (200), i.e., the water jacket housing section (10), is mounted on one side of the cooling device (300) and cools the cooling water passing through the hot passage section (11) and the cooling water passing through the cooling passage section (12) by being cooled by the cooling device (300).

[0079] The heat generated during use of the device is cooled by passing through the device, and the cooling water introduced into the hot flow path (11) is first cooled through heat exchange with the cooling device (300) while passing through the hot flow path (11) in the water jacket housing (10), and then stored again in the cooling water storage tank (100), and the cooling water in the cooling water storage tank (100) is secondarily cooled through heat exchange with the cooling device (300) while passing through the cooling flow path (12) in the water jacket housing (10).

[0080] That is, the cooling water is first cooled when it flows into the cooling water storage tank (100) within the water jacket housing (10) in which the hot flow path (11) and the cooling flow path (12) are integrally provided, and secondarily cooled when it is supplied to the device within the cooling water storage tank (100), so that it can be cooled efficiently.

[0081]

[0082] Meanwhile, the cooling device (300) includes a thermoelectric element (310) having a heat absorption surface mounted on one side of the water jacket housing (10), and a heat sink (320) mounted on the heat dissipation surface of the thermoelectric element (310).

[0083] As an example, the heat sink part (320) has a structure including a heat dissipation plate part having a plurality of thermoelectric elements (310) mounted on one surface, and a plurality of heat dissipation fin parts that are erected and spaced apart from each other on the heat dissipation plate part.

[0084] The heat sink (320) is made of aluminum or aluminum alloy material, which is light and inexpensive, and has high thermal conductivity, as an example. It is also noted that it can be made of a known metal with high thermal conductivity, such as copper.

[0085] The heat sink (320) can be implemented in various ways as a known heat dissipation structure that dissipates heat, so a more detailed description is omitted.

[0086] The thermoelectric element (310) is an example of a Peltier element. When the ends of two different conductors are joined and a direct current voltage is applied to the circuit, one side becomes a heat-absorbing side and the other side becomes a heat-radiating side that radiates the heat absorbed by the heat-absorbing side.

[0087] The thermoelectric element (310) is mounted so that its heat-absorbing surface is in close contact with one surface of the water jacket housing (10), and is provided in multiple numbers to cool the cooling water within the water jacket housing (10), that is, the cooling water passing through the hot passage (11) and the cooling passage (12), respectively.

[0088] And, a heat sink part is mounted on the heat dissipation surface of the thermoelectric element part (310) to effectively release the heat absorbed from the heat absorption surface through the heat dissipation surface, thereby increasing the heat absorption effect on the heat absorption surface.

[0089] In addition, the cooling device (300) further includes a cooling fan unit (330) that is mounted on the heat dissipation fin unit of the heat sink unit (320) and causes air to flow by rotating the fan.

[0090] The cooling fan section (330) blows air inside the heat dissipation fin section to increase the heat dissipation effect of the heat sink section (320), thereby enabling the operation of the thermoelectric element section (310) to more effectively cool the cooling water passing through the water jacket housing section (10).

[0091]

[0092] One embodiment of a cooling device for cooling water according to the present invention has a structure in which a water jacket housing part (10) is provided inside a cooling water circulation structure in which cooling water used for cooling in a device is cooled and then heated and then cooled again and supplied into the device, and a hot passage part (11) through which heated cooling water passes and a cooling passage part (12) through which cooling water supplied to the device passes are each provided therein, and a plurality of thermoelectric element parts (310) effectively cool the cooling water.

[0093]

[0094] The present invention integrates a hot flow path (11) that recovers heated cooling water used for cooling within a device into a tank and a cooling flow path (12) that cools the cooling water stored within the tank and supplies it into the device, thereby increasing cooling efficiency and miniaturizing the size of the cooling device.

[0095] In addition, the present invention can be applied to various skin treatment devices in particular, miniaturizing the main body size and reducing manufacturing costs, thereby greatly improving marketability.

[0096]

[0097] While the present invention has been described in detail using preferred embodiments, the scope of the present invention is not limited to the specific embodiments described above, and should be construed in accordance with the appended claims. Furthermore, those skilled in the art will appreciate that numerous modifications and variations are possible without departing from the scope of the present invention.
