Description

Cooling tip with bonding method and cooling system using the same

[0001] The present invention relates to a structure of a cooling tip for increasing the transfer efficiency of cooling energy, and more specifically, to a cooling tip for effectively transferring cooling energy to a target area by increasing the transfer efficiency of cooling energy from a cooling device to the cooling tip when cooling a target area using a cooling device.

[0002] When local treatment is required, anesthesia may be necessary, and in particular, anesthesia may be performed by cooling the local area to relieve the pain of the needle before injecting the treatment.

[0003] The applicant has developed a cooling device including a cooling module that concentrates cooling energy and a cooling tip that receives cooling energy from the cooling module and delivers it to the target area, so that medical staff can perform cooling anesthesia comfortably and safely. The applicant is currently undergoing FDA approval procedures for a cooling anesthesia device that rapidly cools the eye before an IVT injection procedure.

[0004] In developing the cooling tip, the cooling tip's configuration was divided into a contact portion that contacts the target area and a body to which the contact portion can be mounted. The material of the contact portion was made of metal with high thermal conductivity, and the material of the body was made of plastic with low thermal conductivity to secure an appropriate level of cooling energy transfer efficiency.

[0005] At this time, the contact part of the cooling tip and the main body were joined by a forced fit, but due to tolerances in the part where the contact part of the cooling tip and the main body are joined, in some products, the contact part of the cooling tip and the axis of the cooling medium were not aligned, and a problem occurred in which one side of the cooling tip and one side of the cooling medium were not completely in contact, and in that case, a problem occurred in which the cooling efficiency of the cooling tip was significantly lower than when joined in a normal state, or the cooling degree varied depending on the area of ​​the cooling tip.

[0006] Accordingly, it is necessary to develop a cooling tip that solves the above-mentioned problems and has a small variation in cooling efficiency between products.

[0007] The challenge to be solved is to provide a cooling tip that mitigates the reduction in cooling efficiency that may occur due to misalignment between the cooling module and the cooling tip.

[0008] The challenge to be solved is to provide a cooling tip that is easily aligned so that the axis of the cooling tip is aligned with the axis of the cooling medium.

[0077]

[0078] 1. The need for developing a cooling tip in the form of a bonded joint

[0079] When manufacturing a cooling tip by separating the contact portion and the main body, a process is required to attach the contact portion to the main body for use. This process can result in the contact portion being forcibly fitted to the main body. However, if the contact portion is tilted relative to the main body, the contact portion may be improperly fitted to the main body.

[0080] Figure 1 is a drawing showing a cooling tip that is incorrectly coupled in a state where the axis of the contact portion and the axis of the main body do not align.

[0081] Specifically, the contact portion (3200) is placed on the main body (3100) and is fixedly fitted to the main body (3100) by an external force applied to the contact portion (3200). Since there is no guide (e.g., a rail) that allows the contact portion (3200) to be placed in the correct position on the main body (3100), if the contact portion (3200) receives an external force while being tilted on the main body (3100), the axis (CA5) of the contact portion (3200) and the axis (CA4) of the main body (3100) are incorrectly fitted in a state where they do not align.

[0082] In some cases, even if the contact portion (3200) is tilted relative to the main body (3100), the contact portion (3200) is pushed toward the main body (3100) by an external force received from the cooling medium, and the axis (CA4) of the main body (3100) and the axis (CA5) of the contact portion (3200) are aligned and fixed. However, in the case of a cooling tip in which a tolerance is generated in a direction in which the free space in which the contact portion (3200) can move in the main body (3100) is reduced, the axis (CA4) of the main body (3100) and the axis (CA5) of the contact portion (3200) are fixed in a misaligned state even when an external force is received from the cooling medium.

[0083] Figure 2 is a drawing showing a state in which a cooling medium is inserted into a cooling tip that is incorrectly coupled in a state in which the axis of the contact portion and the axis of the main body do not align.

[0084] When the cooling tip (3000) is mounted on the cooling device and the cooling medium (2110) is inserted into the cooling tip (3000), the axis (CA3) of the cooling medium (2110) and the axis (CA5) of the contact portion (3200) are not aligned. Therefore, even when the cooling medium (2110) is fully inserted into the cooling tip (3000), the cooling medium (2110) and the contact portion (3200) may not be in complete contact (surface contact) due to the tilted axis, and a gap (G) may be generated. When a gap (G) is generated, direct cooling energy is not transferred in the area where surface contact is not formed between the cooling medium (2110) and the contact portion (3200), and cooling energy must be transferred by heat conduction in the area where surface contact is formed. As a result, the cooling efficiency (i.e., heat conduction efficiency), which is a core performance of the cooling device, is bound to be lowered.

[0085] 2. Cooling tip with improved cooling efficiency using a bonding method

[0086] To solve these problems, the applicant developed a cooling tip using a bonding method, which is described below with reference to FIGS. 3 and 4.

[0087] FIG. 3 is a drawing showing a cooling tip in which a contact member is bonded to a tip body according to one embodiment of the present application.

[0088] Specifically, referring to FIG. 3, a joining area (CS) is formed in the tip body, and a contact member (1200) is mounted on the tip body (1100) so that when a part of the contact member (1200) is placed on the joining area (CS) of the tip body (1100), the joining area (CS) has a free space so that the contact member (1200) can move between the contact member (1200) and the tip body (1100).

[0089] Due to this, the contact member (1200) mounted on the tip body (1100) can be placed in a pre-engaged or primary engagement state in which it can move within a certain range before being pressurized by the cooling medium (2110).

[0090] FIG. 4 is a drawing showing a state in which a cooling medium is completely inserted into a cooling tip in which a contact member is bonded to a tip body according to one embodiment of the present application.

[0091] Referring to FIG. 4, when the pre-coupled cooling tip (1000) is mounted on the cooling device (2000), the axis (CA2) of the contact member (1200) moves slightly due to the external force applied by the cooling medium (2110) to the contact member (1200), and when the cooling medium (2110) is completely inserted into the contact member (1200), the axis (CA2) of the contact member (1200) is fixed in alignment with the axis (CA3) of the cooling medium (2110), so that the contact member (1200) can be completely coupled to the tip body (1100).

[0092] When the contact member (1200) is completely coupled to the tip body (1100) and placed in a complete coupling or secondary coupling state, the contact member (1200) can no longer move freely even though there is a coupling space (CS) in the tip body (1100), and the axis (CA2) of the contact member (1200) is fixed in alignment with the axis (CA3) of the cooling medium (2110).

[0093] And, as the axis (CA2) of the contact member (1200) is fixed in a state aligned with the axis (CA3) of the cooling medium (2110) by the cooling medium (2110), the cooling medium (2110) can be sufficiently closely attached (in surface contact) to the contact member (1200).

[0094] As a result, when using a cooling tip (1000) with a forced-fit method, the performance of transferring cooling energy from a cooling medium to a contact member through surface contact can be improved compared to when using a cooling tip (3000) with a conventional forced-fit method.

[0095] 3. Composition of cooling tips

[0096] Hereinafter, a cooling tip (1000) to which a bonding method is applied will be described with reference to FIGS. 5 to 8.

[0097] A cooling tip (1000) according to one embodiment of the present application may include a tip body (1100) and a contact member (1200).

[0098]

[0099] 3.1 Contact member

[0100] FIG. 5 is a drawing showing a cross-section of a contact member cut along a plane including an axis of the contact member according to one embodiment of the present application.

[0101] The contact member (1200) is mounted on the tip body (1100) and can cool the target area. The contact member (1200) has a contact surface (1211) that contacts the target area and can perform a function of transmitting the received cooling energy to the target area.

[0102] The contact member (1200) can be coupled to the tip body (1100) through the coupling area (CS) of the tip body (1100) to be described later. Specifically, the contact member (1200) can be inserted through the insertion portion (1150) of the tip body (1100) and mounted on the tip body (1100) while a part of the contact member (1200) is placed on the coupling area (CS) of the tip body (1100). For example, when the engaging portion (1230) of the contact member (1200) is placed on the coupling area (CS) of the tip body (1100), the contact member (1200) can be pre-coupled to the tip body (1100). Alternatively, if at least a portion of the catch (1230) is placed on the joining area (CS) of the tip body (1100), the contact member (1200) may be pre-joined to the tip body (1100).

[0103] Referring to FIG. 5, the contact member (1200) may include a contact portion (1210), a connecting portion (1220), a catch portion (1230), and an internal space (IS2).

[0104] The contact portion (1210) includes a contact surface (1211) that contacts the target area. Specifically, the contact portion (1210) can make surface contact with the target area through the contact surface (1211) and transfer cooling energy of the contact member to the target area.

[0105] The engaging portion (1230) can mount the contact member (1200) to the tip body (1100). Specifically, the engaging portion (1230) can have a curved shape including a curved surface (1231), and the contact member (1200) can be mounted to the tip body (1100) through the curved shape of the engaging portion (1230). At this time, the engaging portion (1230) of the contact member (1200) can be mounted to the tip body (1100) such that at least a portion thereof is positioned in a joining area (CS) of the tip body (1100) to be described later.

[0106] The connecting portion (1220) may be positioned between the contact portion (1210) and the engaging portion (1230). Specifically, the connecting portion (1220) may be positioned between the contact portion (1210) and the engaging portion (1230) to connect the contact portion (1210) and the engaging portion (1230).

[0107] The internal space (IS2) may refer to a space into which a cooling medium (2110) can be inserted. When the cooling medium (2110) is inserted into the internal space (IS2), cooling energy can be transferred from the cooling medium (2110) to the contact member (1200) through surface contact between the contact member (1200) and the cooling medium (2110). Specifically, when the cooling medium (2110) is inserted into the internal space (IS2), surface contact is formed between the contact portion (1210) of the contact member (1200) and the cooling medium (2110), and cooling energy can be transferred from the cooling medium (2110) to the contact portion (1210).

[0108] The internal space (IS2) may have a shape corresponding to the cooling medium (2110). By having the internal space (IS2) have a shape corresponding to the cooling medium (2110), the space between the contact member (1200) and the cooling medium (2110) inserted into the contact member (1200) can be minimized, thereby increasing the area where surface contact is formed between the contact portion (1210) of the contact member (1200) and the cooling medium (2110).

[0109] The contact member (1200) may be composed of a material with high thermal conductivity. Specifically, the material of the contact member (1200) may be composed of a material with high thermal conductivity so that the cooling energy generated from the cooling device (2000) and transferred to the contact member (1200) can be concentrated on the contact member (1200). For example, the material of the contact member (1200) may be composed of a material with higher thermal conductivity than the tip body (1100) so that the cooling energy can be concentrated on the contact member (1200). Alternatively, the material of the contact member (1200) may be metal, but is not limited thereto.

[0110]

[0111] 3.2 Tip Body

[0112] FIG. 6 is a drawing showing a cross-section of a tip body cut along a plane including an axis of the tip body according to one embodiment of the present application.

[0113] A contact member (1200) may be mounted on the tip body (1100). Specifically, the tip body (1100) equipped with the contact member (1200) may be mounted on a cooling device (2000).

[0114] Referring to FIG. 6, the tip body (1100) may include a first protrusion (1110), a second protrusion (1120), an opening (1130), a mounting portion (1140), an insertion portion (1150), and an insertion space (IS1).

[0115] The first protrusion (1110) can prevent the contact member (1200) mounted on the tip body (1100) from being separated from the tip body (1100). Alternatively, the first protrusion (1110) can perform a function of preventing the contact member (1200) mounted on the tip body (1100) from being protruded more than necessary due to an external force applied to the contact member (1200). Alternatively, the first protrusion (1110) can perform a function of fixing the contact member (1200) without shaking when it is completely or secondarily coupled to the tip body (1100).

[0116] The first protrusion (1110) may be formed on the inside of the tip body (1100). Specifically, the first protrusion (1110) may be formed on the inside of the tip body (1100) so as to protrude further than the surrounding area.

[0117] The first protrusion (1110) may be formed closer to the opening (1130) than the second protrusion (1110) described later. Specifically, the first protrusion (1110) may be formed on the inside of the tip body (1100) closer to the opening (1130) than the second protrusion (1110).

[0118] The first protrusion (1110) has a shape that protrudes in a direction perpendicular to the axis (CA1) of the tip body (1100), and the distance between the first protrusion (1110) and the first protrusion (1110) formed at a position symmetrical with respect to the axis (CA1) of the tip body (1100) may be smaller than the distance between the engaging portions (1230) of the contact member (1200). Through this, when the contact member is mounted on the tip body, the contact member can be prevented from being separated from the tip body.

[0119] Additionally, the first protrusion (1110) may have a shape that extends in a direction parallel to the axis (CA1) of the tip body (1100). In other words, the first protrusion (1110) may have a shape that extends longer than the second protrusion (1120). Through this, the contact member (1200) can withstand an external force applied by the cooling medium (2110).

[0120] In addition, the first protrusion (1110) may include a first region (1111) having a shape corresponding to the catch (1230) of the contact member (1200). Specifically, the first region (1111) of the first protrusion (1110) may have a shape corresponding to the curved surface (1231) of the catch (1230). For example, if the curved surface (1231) of the catch (1230) is a curved surface, the first region (1111) of the first protrusion (1120) may be a curved surface. Since the first region (1111) and the curved surface (1231) have shapes corresponding to each other, the first region (1111) and the curved surface (1231) can make surface contact, and since frictional force is generated, the contact member (1200) can withstand to some extent even if it receives an external force from the cooling medium (2110), and as a result, the contact member (1200) can be prevented from protruding outward from the tip body (1100) or being separated from the tip body (1100) more than necessary.

[0121] FIG. 7 is a drawing showing a cooling tip with a contact member mounted on a tip body, viewed from a direction facing the contact surface of the contact member according to one embodiment of the present application.

[0122] Referring to FIG. 7, the first protrusions (1110) may be formed in multiple numbers. For example, four first protrusions (1110) may be formed on the tip body (1100). As another example, two first protrusions (1110) may be formed on the tip body (1100), but the present invention is not limited thereto. In this case, the first protrusions (1110) formed in multiple numbers may be formed at positions having equal intervals from each other so as to be able to uniformly withstand the force of the cooling medium (2110).

[0123] Again, referring to FIG. 6, the second protrusion (1120) may be formed on the inside of the tip body (1100) to prevent the contact member (1200) mounted on the tip body (1100) from being separated from the tip body (1100). Specifically, the second protrusion (1120) may be formed on the inside of the tip body (1100) to protrude further than the surrounding area.

[0124] The second protrusion (1120) is formed closer to the insertion portion (1150) of the tip body (1100) than the first protrusion (1100), thereby preventing the contact member (1200) mounted on the tip body (1100) from being dislodged toward the insertion portion (1150) of the tip body (1100).

[0125] The second protrusion (1120) may be formed at a position spaced apart from the first protrusion (1110) formed on the inside of the tip body (1100) by a certain distance or more. As the second protrusion (1120) is formed at a position spaced apart from the first protrusion (1110) by a certain distance or more, a joining area (CS) may be formed in the tip body (1100).

[0126] The bonding area (CS) may refer to a space between the first protrusion (1110) and the second protrusion (1120) of the tip body (1100). Alternatively, the bonding area (CS) may refer to a region where the engaging portion (1230) of the contact member (1200) is positioned between the first protrusion (1110) and the second protrusion (1120) of the tip body (1100) so that the contact member (1200) is bonded to the tip body (1100).

[0127] The distance between the first protrusion (1110) and the second protrusion (1120) may be determined as a distance that allows a free space for the contact member (1200) to move. According to one embodiment, the distance between the first protrusion (1110) and the second protrusion (1120) may be greater than the thickness of the engaging portion (1230) of the contact member (1200), but is not limited thereto.

[0128] The second protrusion (1120) may include a second region (1121) having a curved surface. Since the second region (1121) of the second protrusion (1120) is formed as a curved surface, the engaging portion (1230) of the contact member (1200) located between the insertion portion (1150) and the second protrusion (1120) can be pushed and moved between the first protrusion (1110) and the second protrusion (1120) by an external force without damaging the shape of the second protrusion (1120). At this time, the curvature of the curved surface may be determined to correspond to the curved shape of the contact member (1200) so that the contact member (1200) can be more easily mounted on the tip body (1100).

[0129] The opening (1130) may refer to a portion that is open at one end of the tip body (1100). A portion of the contact member (1200) mounted on the tip body (1100) may protrude to the outside of the tip body (1100) through the opening (1130). For example, the contact portion (1210) of the contact member (1200) may protrude to the outside of the tip body (1100). For a specific example, the contact surface (1211) of the contact member may protrude to the outside of the tip body. As the contact member (1200) protrudes to a portion, the contact member (1200) can easily come into contact with the target area.

[0130] The mounting portion (1140) can mount the tip body (1100) or the tip body (i.e., the cooling tip (1000)) coupled with the contact member to the cooling device (2000) to be described later. The cooling tip (1000) can be mounted and detached from the cooling device (2000) through the mounting portion (1140). Accordingly, the cooling tip (1000) can be provided as a disposable or replaceable type, and can safely and hygienically transfer the cooling energy generated from the cooling device (2000) to the target area to cool it.

[0131] The mounting portion (1140) may be formed on the outside of the tip body (1100) and may have a shape corresponding to the coupling member (2220) of the cooling device (2000). According to one embodiment, the mounting portion (1140) may have a groove shape corresponding to the coupling member (2220) so that it can be mounted to the cooling device (2000).

[0132] The insertion portion (1150) is a portion that is open at the other end of the tip body (1100), and the contact member (1200) can be inserted into the tip body (1100) through the insertion portion (1150). Alternatively, a cooling medium (2110) can be inserted through the insertion portion (1150). Alternatively, a cooling medium receiving member (2120) can be inserted through the insertion portion (1150).

[0133] The insertion space (IS1) may refer to a space formed inside the tip body (1100). Specifically, the insertion space (IS1) may refer to a space formed inside the tip body (1100) into which a cooling medium (2110), a contact member (1200), or a cooling medium receiving member (2120) may be inserted. Alternatively, the insertion space (IS1) may refer to a hollow space formed inside the tip body.

[0134] FIG. 8 is a cross-sectional view of a tip body and a contact member according to one embodiment of the present application.

[0135] Referring to FIG. 8, the insertion space (IS1) of the tip body (1100) may include a mounting area (IS11) and an insertion area (IS12).

[0136] The insertion area (IS12) may refer to an area where a cooling medium (2110) is inserted into the tip body (1100). Alternatively, the insertion area (IS12) may refer to an area where a cooling medium receiving member (2120) is inserted into the tip body (1100). Alternatively, the insertion area (IS12) may refer to an area where a contact member (1200) is inserted. Specifically, the contact member (1200) may be inserted into the insertion area (IS12) of the tip body (1100) through the insertion portion (1240) and mounted in the mounting area (IS11) of the tip body (1100) described below.

[0137] The mounting area (IS11) may refer to an area where the contact member (1200) is mounted on the tip body (1100). Alternatively, the mounting area (IS11) may refer to an internal space from the second protrusion (1120) to the opening (1130) in the tip body (1100).

[0138] The mounting area (IS11) may include a first protrusion (1110), a second protrusion (1120), and an opening (1130).

[0139] In the mounting area (IS11), the tip body (1100) may have a shape capable of performing a pre-engagement in which the contact member (1200) is mounted and can move within a certain range.

[0140] Below, with reference to FIG. 8, the shape of the tip body (1100) capable of being coupled in the mounting area (IS11) is specifically described.

[0141] The distance between the first protrusion (1110) and the second protrusion (1120) of the tip body (1100) is spaced apart by a certain distance or more. According to one embodiment, the distance between the first protrusion (1110) and the second protrusion (1120) may be greater than the thickness of the engaging portion (1230) of the contact member (1200).

[0142] If the distance between the first protrusion (1110) and the second protrusion (1120) is equal to the thickness of the engaging portion (1230) of the contact member (1200), the width (W1) of the inner side of the tip body (1100) located between the first protrusion (1110) and the second protrusion (1120) so that a movable space can be formed when the contact member (1200) is mounted on the tip body (1100) is greater than the length (L1) between the engaging portions (1230) of the contact member (1200), and the width (W2) between the first protrusion (1110) and the first protrusion (1110) formed at a symmetrical position with respect to the axis (CA1) of the tip body (1100) can be greater than the width (L2) of the connecting portion (1220) of the contact member (1200).

[0143] When the contact member (1200) is mounted on the tip body (1100), a free space may be formed between the outer side of the contact member (1200) and the inner side of the tip body (1100) so that the contact member (1200) can move in a direction perpendicular to the axis (CA1) of the tip body (1100). According to one embodiment, the width (W1) of the inner side of the tip body (1100) located between the first protrusion (1110) and the second protrusion (1120) may be greater than the length (L1) between the engaging portions (1230) of the contact member (1200). Accordingly, when the contact member (1200) is mounted on the tip body (1100), the engaging portion (1230) of the contact member (1200) may be spaced apart from the inside of the tip body (1100) located between the first protrusion (1110) and the second protrusion (1120). According to another embodiment, the width (W2) between the first protrusion (1110) and the first protrusion (1110) formed at a symmetrical position with respect to the axis (CA1) of the tip body (1100) may be greater than the width (L2) of the connecting portion (1220) of the contact member (1200). Accordingly, when the contact member (1200) is mounted on the tip body (1100), the connecting portion (1220) of the contact member (1200) may be spaced apart from the first protrusion (1110) of the tip body (1100). According to another embodiment, the width (W1) of the inner side of the tip body (1100) positioned between the first protrusion (1110) and the second protrusion (1120) may be greater than the distance (L1) between the engaging portions (1230) of the contact member (1200), and the distance (W2) between the first protrusion (1110) and the first protrusion (1110) formed at a symmetrical position with respect to the axis (CA1) of the tip body (1100) may be greater than the width (L2) of the connecting portion (1220) of the contact member (1200).

[0144]

[0145] When the contact member (1200) is mounted on the tip body (1100), a free space may be formed between the outer side of the contact member (1200) and the inner side of the tip body (1100) so that the contact member (1200) can move in a direction intersecting the axis (CA1) of the tip body (1100). According to one embodiment, the distance between the first protrusion (1110) and the second protrusion (1120) may be greater than the thickness of the engaging portion (1230) of the contact member (1200), and at this time, the width (W1) of the inner side of the tip body (1100) between the first protrusion (1110) and the second protrusion (1120) may be greater than or equal to the distance (L1) between the engaging portions (1230) of the contact member (1200). According to another embodiment, the distance between the first protrusion (1110) and the second protrusion (1120) may be greater than the thickness of the engaging portion (1230) of the contact member (1200), and at this time, the distance (W2) between the first protrusion (1110) and the first protrusion (1110) formed at a symmetrical position with respect to the axis (CA1) of the tip body (1100) may be greater than or equal to the width (L2) of the connecting portion (1220) of the contact member (1200). According to another embodiment, the distance between the first protrusion (1110) and the second protrusion (1120) may be greater than the thickness of the engaging portion (1230) of the contact member (1200), and at this time, the width (W1) of the inner side of the tip body (1100) located between the first protrusion (1110) and the second protrusion (1120) may be greater than or equal to the distance (L1) between the engaging portions (1230) of the contact member (1200), and the distance (W2) between the first protrusion (1110) and the first protrusion (1110) formed at a symmetrical position with respect to the axis (CA1) of the tip body (1100) may be greater than or equal to the width (L2) of the connecting portion (1220) of the contact member (1200).

[0147] 4. Cooling device configuration

[0148] Below, the process of completely bonding the cooling tip (1000) in a pre-bonded state while being mounted on the cooling device (2000) is described.

[0149] Before explaining the process of completely coupling the cooling tip (1000) in a pre-coupling state to the cooling device (2000), the configuration of the cooling device (2000) will be explained with reference to FIGS. 9 and 10.

[0150] FIG. 9 is a drawing illustrating a cooling tip and a cooling device according to one embodiment of the present application.

[0151] Referring to FIG. 9, the cooling tip (1000) can be mounted to or detached from the cooling device (2000). Specifically, the cooling tip (1000) can be mounted to or detached from the cooling device (2000) along the axis (CA6).

[0152] The cooling device (2000) can cool a target area by generating cooling energy and providing it to the target area. At this time, the cooling energy generated by the cooling device (2000) can be safely and efficiently transferred to the target area through the cooling tip (1000) mounted on the cooling device (2000).

[0153] FIG. 10 is a drawing showing the configuration of a cooling device and a cooling tip according to one embodiment of the present application.

[0154] Referring to FIG. 10, the cooling device (2000) may include a cooling module (2100), a coupling module (2200), an elastic member (2300), a sensor module (2400), a blower fan (2500), an input module (2600), an output module (2700), and a control module (2800).

[0155] Below, each component is described in detail.

[0156] The cooling module (2100) can generate and provide cooling energy to be delivered to a target area. The cooling module (2100) can include a cooling medium (2110), a cooling medium receiving member (2120), a temperature control member (2130), and a heat dissipation member (2140). The cooling module (2100) can control the temperature of the cooling medium (2110) using the temperature control member (2130) and provide cooling energy to the cooling tip (1000) through the cooling medium (2110).

[0157] The cooling medium (2110) can be thermally coupled to the cooling tip (1000) to provide cooling energy. Specifically, the cooling medium (2110) can provide cooling energy by making surface contact with the contact member (1200) of the cooling tip (1000).

[0158] The cooling medium (2110) may be made of a material with high thermal conductivity to efficiently transfer cooling energy. For example, the cooling medium (2110) may be made of gold (Ag), silver (Au), copper (Cu), aluminum (Al), or a combination thereof.

[0159] The cooling medium receiving member (2120) can receive the cooling medium (2110). For example, the cooling medium receiving member (2120) can surround the cooling medium (2110) and support the cooling medium (2110) within the cooling device (2000). In addition, the cooling medium receiving member (2120) can be physically coupled to the tip body (1100) of the cooling tip (1000) such that the cooling medium (2110) is thermally coupled to the contact member (1200) of the cooling tip (1000).

[0160] The cooling medium receiving member (2120) may be made of a material with low thermal conductivity to prevent the dispersion of cooling energy provided to the cooling medium (2110). For example, the cooling medium receiving member (2120) may include a material such as plastic to prevent cooling loss of the cooling medium (2110).

[0161] The cooling medium receiving member (2120) can be bonded to the cooling medium (2110) in close contact to prevent the cooling medium (2110) from coming into contact with air, thereby minimizing moisture condensed in the cooling medium (2110) during cooling.

[0162] The temperature control member (2130) can control the temperature of the cooling medium (2110). For example, the temperature control member (2130) can receive a control signal from the control module (2800) described below and provide cooling energy or heat energy to the cooling medium (2110).

[0163] The temperature control member (2130) may be implemented in various forms. For example, the temperature control member (2130) may include a thermoelectric element that uses the Peltier effect to receive current and, depending on the direction of the applied current, absorb heat on one side and generate heat on the other side. For another example, the temperature control member (1130) may include a device or element that uses a thermodynamic cycle such as a stirling cooler or a vapor compression refrigeration cycle, or a Houle-Thomson method using an expanding gas. As another example, the temperature control member (2130) may produce or provide cooling energy using a coolant such as carbon dioxide or liquid nitrogen.

[0164] The temperature control member (2130) may be thermally coupled to the cooling medium (2110). For example, the temperature control member (2130) may be in surface contact with at least a portion of the cooling medium (2110) to provide cooling energy or thermal energy.

[0165] The heat dissipation member (2140) can discharge heat generated by the operation of the cooling module (2100) to the outside. For example, the heat dissipation member (2140) can receive heat generated by the temperature control member (2130) generating cooling energy and discharge it to the outside of the cooling device (2000).

[0166] The coupling module (2200) may refer to a configuration for coupling a cooling tip (1000) among cooling devices (2000). For example, the cooling tip (1000) may be mounted on or detached from the cooling device (2000) through the coupling module (2200).

[0167] The coupling module (2200) can support the internal configuration of the cooling device (2000). For example, the cooling module (2100) can be placed inside the cooling device (2000) by inserting the cooling medium (2110) and the cooling medium receiving member (2120) of the cooling module (2100) into the coupling module (2200).

[0168] Furthermore, the coupling module (2200) may be connected to the cooling module (2100). For example, the cooling module (2100) may be physically mounted, fixed, or coupled to the coupling module (2200). Specifically, the cooling module (2100) may be coupled to the coupling module (2200) via an elastic member (2300) described below.

[0169] The coupling module (2200) may include a base (2210) and a coupling member (2220).

[0170] The base (2210) may refer to the body of the coupling module (2200). For example, the base (2210) may include a portion into which the cooling medium receiving member (2120) of the cooling module (2100) is inserted and the cooling tip (1000) is mounted. In addition, a coupling member (2220) for mounting and detaching the cooling tip (1000) may be fixed to the base (2210).

[0171] The base (2210) may refer to a means for physically connecting the elastic member (2300) to the coupling module (2200). For example, one end of the elastic member (2300) may be fixed to the base (2210) via at least one fixed pin.

[0172] The coupling member (2220) may refer to a means for mounting and detaching the cooling tip (1000) from the coupling module (2200). For example, the cooling tip (1000) may be mounted to or detached from the cooling device (2000) depending on the operation of the coupling member (2220). Specifically, the coupling member (2220) may include a screw coupling, a mechanical latch coupling, a magnetic coupling, a force fit, etc.

[0173] The coupling module (2200) may include a plurality of fixed pins for coupling the elastic member (2300) and the coupling member (2220) to the base (2210).

[0174] The elastic member (2300) can connect the cooling module (2100) and the coupling module (2200). For example, one end of the elastic member (2300) can be connected to the coupling module (2200) and the other end can be connected to the cooling module (2100).

[0175] The elastic member (2300) can provide elasticity. For example, the elastic member (2300) can provide elasticity in a direction opposite to the direction in which the cooling tip (1000) is mounted on the cooling device (2000) so that the cooling module (2100) can press the cooling tip (1000). As another example, the elastic member (2300) can provide elasticity in the direction of the central axis of the cooling module (2100) so that the cooling module (2100) can move within the cooling device (2000).

[0176] Meanwhile, the elastic member (2300) may be replaced or omitted. For example, the cooling module (2100) may be physically coupled to the cooling device (2000) and fixed to a specific location within the cooling device (2000). Specifically, the cooling module (2100) may be fixed by a plurality of ribs provided within the body of the cooling device (2000). Alternatively, the cooling module (2100) may be inserted into the coupling module (2200) and fixed thereto by means of screw coupling or the like, and may be placed within the cooling device (2000).

[0177] The sensor module (2400) can detect the physical characteristics of the cooling device (2000). Specifically, the sensor module (2400) can detect the temperature or electrical characteristics of the cooling medium (2110). For example, the sensor module (2400) can be directly or indirectly coupled to the cooling medium (2110) to measure the current, voltage, or temperature of the cooling medium (2110).

[0178] The sensor module (2400) may include a contact-type temperature sensor such as a thermocouple, a resistance temperature detector (RTD), a thermistor, an IC temperature sensor, or a non-contact temperature sensor using infrared rays. Alternatively, the sensor module (2400) may include an analog or electronic circuit for measuring electrical characteristics such as current or voltage.

[0179] Additionally, the sensor module (2400) may include a touch sensor or a pressure sensor to determine whether the cooling tip (1000) or the cooling device (2000) has contacted the target surface.

[0180] Meanwhile, the sensor module (2400) can detect whether the cooling tip (1000) is mounted or detached from the cooling device (2000). Alternatively, the sensor module (2400) can measure the pressure applied by the cooling device (2000) or the cooling tip (1000) to the target or target surface. For this purpose, the sensor module (2400) can include a pressure sensor.

[0181] The sensor module (2400) can provide the detected physical characteristics of the cooling device (2000) to the control module (2800). For example, the sensor module (2400) can provide the control module (2800) with a signal indicating real-time temperature values, voltage / current values, or whether the cooling tip (1000) is mounted or detached from the cooling device (2000).

[0182] The blower fan (2500) can induce air flow within the cooling device (2000). For example, the blower fan (2500) can receive a control signal from the control module (2800) and control the air flow to exhaust internal heat generated as the cooling device (2000) produces cooling energy to the outside of the cooling device (2000).

[0183] The blower fan (2500) may be positioned close to the heat dissipation member (2140). For example, the heat dissipation member (2140) may include heat dissipation fins to dissipate heat to the outside, and the blower fan (2500) may be positioned close to the heat dissipation fins to move air that comes into contact with the heat dissipation fins to the outside.

[0184] The input module (2600) can receive user input from a user. User input can take various forms, including button input, key input, touch input, and voice input. For example, the input module (2600) is a comprehensive concept that includes various input means that detect or receive various forms of user input, such as buttons that can be pressed by a user, a touch sensor that detects the user's touch, a microphone that receives user voice input, and other various forms of user input.

[0185] The output module (2700) can output various types of information and provide them to the user. The output module (2700) is a comprehensive concept that includes a display that outputs images, a speaker that outputs sound, a haptic device that generates vibrations, and various other types of output means.

[0186] The control module (2800) can control the overall operation of the cooling device (2000). For example, the control module (2800) can load and execute a program for the operation of the cooling module (2100). For a specific example, the control module (2800) can control the temperature control member (2130) to cool the cooling medium (2110) to perform cooling, and can control the blower fan (2500) to perform a heat dissipation function. For another specific example, the control module (2800) can control the operation of the cooling device according to user input by controlling the input module (2600) and the output module (2700), and can provide specific information to the user.

[0187] Meanwhile, the cooling device (2000) may further include a memory that stores a control program loaded or executed from the control module (2800), although not shown in FIG. 10, and a power supply unit that supplies power required for the operation of the cooling device (2000).

[0188] So far, one embodiment of a cooling device has been described. However, FIGS. 9 and 10 only describe a cooling device according to one embodiment. The cooling tip disclosed in this specification can also be used in cooling devices according to other embodiments. For example, it can be applied to cooling devices that do not utilize the detachment of the cooling tip via an elastic member, but is not limited thereto.

[0189]

[0190] 5. The process of installing the cooling tip on the cooling device

[0191] Below, with reference to Fig. 11, the process of completely coupling the cooling tip (1000) in a pre-coupling state while being mounted on the cooling device (2000) will be described.

[0192] FIG. 11 is a drawing illustrating a process in which the axis of a contact member is fixed while a cooling tip in a pre-bonded state according to one embodiment of the present application is mounted on a cooling device.

[0193]

[0194] 5.1 Primary Axis Alignment Process

[0195] Figure 11(a) illustrates a state at a time when the cooling tip (1000) is mounted on the cooling device (2000) and the cooling medium (2110) is inserted into the tip body (1100) but not inserted into the contact member (1200).

[0196] Referring to Fig. 11(a), it can be confirmed that the primary axis alignment process is performed when the cooling medium (2110) is inserted into the tip body (1100) but not inserted into the contact member (1200).

[0197] The primary axis alignment process may refer to a process in which the axis of the cooling medium receiving member (2120) and the axis (CA1) of the tip body (1100) are aligned. Through the primary axis alignment process, the axis (CA3) of the cooling medium (2110) may be aligned with the axis (CA1) of the tip body (1100).

[0198] At this time, the contact member (1200) may be in a state of being provisionally coupled or primarily coupled to the tip body (1100). The contact member (1200) primarily coupled to the tip body (1100) is in a state where it can move within the first range (α) when an external force is applied to the contact member (1200).

[0199] The first range (α) can be determined by the free space formed by the gap between the contact member (1200) pre-coupled to the tip body (1100) and the tip body (1100). Specifically, the first range (α) can be determined by the distance between the contact member (1200) pre-coupled to the tip body (1100) and the tip body (1100).

[0200]

[0201] 5.2 Secondary axis alignment process

[0202] Figure 11(b) illustrates a state at a point in time when the cooling tip (1000) is mounted on the cooling device (2000) and the cooling medium (2110) is inserted into the tip body (1100) and the contact member (1200), but before being fully inserted to the end of the contact member (1200).

[0203] Referring to FIG. 11(b), a secondary axis alignment process may be performed as the cooling medium (2110) continues to be inserted into the tip body (1100) and also begins to be inserted into the contact member (1200).

[0204] The secondary axis alignment process may refer to a process in which the axis (CA2) of the contact member (1200) is aligned with the axis (CA3) of the cooling medium (2110). Alternatively, the secondary axis alignment process may refer to a process in which the contact member (1200) moves by an external force. Specifically, the secondary axis alignment process may refer to a process in which the axis (CA2) of the contact member (1200) moves slightly by an external force applied to the contact member (1200) by the cooling medium (2110) as the cooling medium (2110) is inserted into the internal space (IS2) of the contact member (1200).

[0205] In the second axis alignment process, the axis (CA2) of the contact member (1200) can move within a second range (β). The second range (β) may be less than or equal to the first range (α).

[0206] The second range (β) may gradually decrease. Specifically, as the cooling medium (2110) is inserted into the internal space (IS2) of the contact member (1200), the second range (β) may gradually decrease. For example, when the cooling medium (2110) is inserted into the contact member (1200), the axis (CA2) of the contact member (1200) may move within the second range (β), and in this state, when the cooling medium (2110) is further inserted into the contact member (1200), the range in which the axis (CA2) of the contact member (1200) may move may become smaller than the second range (β).

[0207] That is, when the cooling medium (2110) begins to be inserted into the contact member (1200) and before the insertion is completed, the contact member (1200) mounted on the tip body (1100) begins to move by the cooling medium (2110) and moves little by little, and the axis (CA2) of the contact member (1200) also moves little by little, and the range of movement may decrease depending on the degree to which the cooling medium (2110) is inserted.

[0208] Through the secondary axis alignment process described above, even if the contact member (1200) is incorrectly coupled to the tip body (1100) and their axes do not match or are not aligned and are tilted, the contact member (1200) can move slightly, so that the axis (CA2) of the contact member (1200) can gradually get closer to the axis (CA3) of the cooling medium (2110) during the process of inserting the cooling medium (2110) into the contact member (1200).

[0209]

[0210] 5.3 Full bonding or secondary bonding

[0211] Figure 11(c) shows the state at which the cooling medium (2110) of the cooling device (2000) is completely inserted into the contact member (1200).

[0212] Referring to FIG. 11(c), when the cooling medium (2110) is fully inserted into the contact member (1200), the contact member (1200) can be fully bonded or secondarily bonded to the tip body (1100).

[0213] Complete engagement or secondary engagement may mean a state in which the contact member (1200) mounted on the tip body (1100) no longer moves even though there is free space.

[0214] When fully coupled, the axis (CA2) of the contact member (1200) can be fixed in alignment with the axis (CA3) of the cooling medium (2110). Alternatively, when fully coupled, the axis (CA2) of the contact member (1200) can be aligned or matched with the axis (CA3) of the cooling medium (2110). Specifically, since the axis (CA2) of the contact member (1200) is gradually moved by the cooling medium (2110) through the secondary axis alignment process and gradually gets closer to the axis (CA3) of the cooling medium (2110), when the cooling medium (2110) is fully inserted into the contact member (1200), the axis (CA2) of the contact member (1200) can be aligned or matched with the axis (CA3) of the cooling medium (2110). Therefore, when the cooling medium (2110) is fully inserted to the end of the contact member (1200), the axis (CA2) of the contact member (1200) can be fixed in alignment with the axis (CA3) of the cooling medium (2110).

[0215] Due to this, surface contact can be formed between the contact member (1200) and the cooling medium (2110). Specifically, the area where surface contact is formed between one surface of the contact member (1200) and one surface of the cooling medium (2110) can increase, and the cooling energy transfer performance due to the surface contact can increase.

[0216]

[0217] Through the process illustrated in FIG. 11, the axis (CA2) of the contact member (1200) can be fixed while being aligned or matched with the axis (CA3) of the cooling medium (2110). In particular, even if the contact member (1200) is incorrectly mounted to the tip body (1100) such that the axis (CA2) of the contact member (1200) does not match or is tilted with the axis (CA1) of the tip body (1100), the axis (CA2) of the contact member (1200) can be fixed while being aligned or matched with the axis (CA3) of the cooling medium (2110) through the process illustrated in FIG. 11.

[0218] In addition, since the axis (CA2) of the contact member (1200) is fixed by the cooling medium (2110), the area where surface contact is formed between the contact member (1200) and the cooling medium (2110) increases, and the cooling efficiency (i.e., heat conduction efficiency), which is the performance of cooling energy transfer through surface contact, can increase.

[0219]

[0220] 6. Experiment

[0221] Hereinafter, an experiment is described with reference to FIGS. 12 and 13 to confirm that the thermal conductivity efficiency is increased when a cooling tip with a forced-fit method according to an embodiment of the present application is mounted on a cooling device compared to a conventional cooling tip with a forced-fit method.

[0222] Figure 12 is a diagram showing the experimental results showing the temperature difference by area of ​​the contact surface of various types of cooling tips according to the bonding method and tolerance.

[0223] Figure 13 is a drawing of the cooling tip viewed from a direction facing the contact surface of the contact member to explain the area of ​​the cooling tip where the temperature was measured in the experiment.

[0224] The outline of the experimental process involved manufacturing a total of four cooling tips, each of which was mounted on an identical cooling device to cool the target area to the same temperature. The cooling device, as described in Figs. 9 and 10, comprised a product comprising a cooling module, a coupling module, an elastic member, a sensor module, a blower fan, an input module, an output module, and a control module.

[0225] And, for each cooling tip, the temperature of the cooling medium and the contact member in the four areas (P1, P2, P3, P4) shown in Fig. 13 was measured.

[0226] Specifically, regarding the cooling tips used in the experiment, cooling tips were manufactured by using different methods of joining the cooling tips to confirm that the cooling tips with a forced-fit method showed higher heat conduction efficiency than the cooling tips with a forced-fit method.

[0227] Additionally, cooling tips were manufactured with different tolerances to verify the thermal conductivity efficiency of the cooling tips according to tolerance.

[0228] The four cooling tips used in the experiment are described in detail below.

[0229] Test 1: The first cooling tip (CT1) was manufactured to be joined by a forced fit method and to have an interference area of ​​0.3 mm or more on one side (i.e., a tolerance of 0.6 mm or more).

[0230] Test 2: The second cooling tip (CT2) was manufactured to be joined by a force-fit method and to create an interference area of ​​0.05 mm on one side (i.e., tolerance is 0.1 mm).

[0231] Test 3: The third cooling tip (CT3) was fitted with a force-fit method and was manufactured to be a fixed number without interference (i.e., without tolerance).

[0232] Test 4: The fourth cooling tip (CT4) was manufactured to be bonded in a pre-bonded manner and to have a tolerance of 0.1 mm or more on one side (i.e., tolerance of 0.2 mm or more).

[0233] Here, the cooling tip to which the forced fit method is applied is manufactured so that the width (L2) of the connection portion of the contact member is larger than the width (W2) between the first protrusion of the tip body and the first protrusion formed at a position symmetrical with respect to the axis of the tip body, so that an interference section in which the contact member and the tip body overlap may be formed depending on the tolerance.

[0234] For example, manufacturing a cooling tip with a forced fit method so that an interference section of 0.3 mm or more on one side means that an interference section is formed in which the contact member overlaps the first protrusion of the tip body by 0.3 mm or more. Alternatively, it means that the cooling tip is manufactured so that the width of the connecting portion of the contact member is longer by at least twice the length on one side (i.e., at least 0.6 mm) than the width between the first protrusion of the tip body and the first protrusion formed at a position symmetrical with respect to the axis of the tip body, so that an interference section in which the contact member and the first protrusion of the tip body overlap by 0.3 mm or more can be formed.

[0235] As described above, four cooling tips with different bonding methods and tolerances were mounted on the same cooling device to cool the target area to the same temperature.

[0236] And, in order to confirm whether the surface contact between the cooling medium of the cooling device and the contact member of the cooling tip was good, four areas (P1, P2, P3, P4) of the contact surface were specified as illustrated in Fig. 13, and the temperature of the cooling medium and the contact member in each area was measured. Specifically, among the areas where the cooling medium and the contact member must be in surface contact to transfer cooling energy, four areas spaced at 90-degree intervals were selected and the temperature was measured.

[0237] In the graph of Fig. 12, the X-axis represents the four areas shown in Fig. 12, and the Y-axis represents the dT value. Here, the dT value represents the absolute value of the difference between the temperature of the cooling medium and the temperature of the contact member.

[0238] At this time, the smaller the difference between the temperature of the cooling medium and the temperature of the contact member, the better the cooling energy transfer due to surface contact between the cooling medium and the contact member. Therefore, the smaller the dT value shown in the graph of Fig. 12, the more the area where surface contact between the cooling medium and the contact member is formed in the selected area among P1 to P4 increases. In addition, the larger the dT value, the more the area where surface contact between the cooling medium and the contact member is not formed in the selected area increases.

[0239] Referring to Fig. 12, the results show that the fourth cooling tip (CT 4) with the bonding method applied has a smaller dT value in all four areas (P1, P2, P3, P4) than the first to third cooling tips (CT1, CT2, CT3) with the forced-fit method applied. Through this result, it was confirmed that the cooling tip with the bonding method applied has a higher cooling energy transfer efficiency due to the surface contact because the area where the cooling medium and the contact member form surface contact increases compared to the conventional forced-fit method.

[0240] In addition, the more uniform the difference between the temperature of the cooling medium and the temperature of the contact member, the more the cooling performance of the cooling device equipped with the cooling tip can be. This is because cooling energy must be transferred to as many areas as possible within the contact area between the target area and the cooling tip to cool the specific target area quickly and accurately. Therefore, if the dT values ​​in the four areas (P1 to P4) for each cooling tip used in the experiment are the same or similar and have a uniform value, the cooling performance of the cooling device equipped with the cooling tip can be further improved.

[0241] Referring to Fig. 12, it was confirmed that the 4th cooling tip (CT4) with the bonding method applied and the 1st cooling tip (CT1) and 2nd cooling tip (CT2) with the force-fit method applied had uniform dT values ​​in the 4 regions (P1, P2, P3, P4) with no significant difference. However, the 1st cooling tip (CT1) with the force-fit method applied showed a large difference in the dT values ​​of P1 and P4 in particular, confirming that the dT values ​​were not uniform in the 4 regions (P1, P2, P3, P4).

[0242] That is, it can be seen that the cooling performance of the cooling device may be reduced depending on the tolerance of the cooling tip using the forced fit method compared to the cooling tip using the pre-fit method. Specifically, as the tolerance of the cooling tip using the forced fit method increases, the amount of cooling energy transferred from the cooling medium to the cooling tip becomes uneven, making it difficult to cool the target area quickly and accurately. Therefore, if a cooling tip using the forced fit method is to be used in a cooling device, it may be inefficient because it requires a lot of cost and time for tolerance management when manufacturing the cooling tip. However, the cooling tip using the pre-fit method can not only improve the cooling performance of the cooling device even if tolerance occurs during the manufacturing process, but also be more efficient because the cost and time consumed for tolerance management are reduced.

[0243] In conclusion, the experiment confirmed that the cooling tip with a bonding method has better cooling energy transfer performance, can cool the target area quickly and accurately, and can easily manage tolerances.
