In addition, components having the same functions within the scope of the same concept shown in the drawings of each exemplary embodiment are described using the same reference numerals, and repeated descriptions are omitted herein.

[0062] When it is determined that the detailed description of known functions or structures related to the present disclosure may unnecessarily obscure the subject matter of the present disclosure, the detailed description is omitted. In addition, the numbers (e.g., first, second, etc.) used in the description of the present disclosure are only identifications for distinguishing one component from another component.

[0063] Furthermore, the suffixes “module” and “unit” used for components used in the following embodiments are given or used merely for convenience of description, and are not intended to have different meanings or roles by themselves.

[0064] In the following exemplary embodiments, a singular expression includes a plural number unless the context clearly dictates otherwise.

[0065] In the following exemplary embodiments, terms such as “including” and “having” imply the presence of features or components described in the present disclosure, and do not exclude the possibility of adding one or more other features or components.

[0066] In the drawings, the size of components may be exaggerated or reduced for convenience of explanation. For example, the size and thickness of each configuration shown in the drawings are arbitrary for the purpose of explanation, and do not necessarily limit the present disclosure as shown.

[0067] When a certain exemplary embodiment may be alternatively implementable, a specific processing order different from the order in which the processes are described may be performed. For example, two processes described in succession may be performed substantially simultaneously, or may be performed in an order opposite to the order described.

[0069] Below, a filter module including a filter and / or a sealing member according to various exemplary embodiments of the present disclosure that can be used for a cooling device will be described in detail with reference to the accompanying drawings. In one example, the present disclosure may disclose an exemplary embodiment of the shape of the filter. In another example, the present disclosure may disclose an exemplary embodiment of the shape of the sealing member included in the filter module.

[0070] Figure 1 FIG. 1 is a schematic diagram showing a cooling device including a filter module according to an exemplary embodiment of the present disclosure. Figure 2 FIG. 1 is a schematic diagram showing a cooling system including a filter module according to an exemplary embodiment of the present disclosure.

[0071] The cooling device may include a main body, a coolant storage unit, and a filter module.

[0072] The main body can be hand-held. In addition, the main body can accommodate a nozzle for spraying coolant and a valve for controlling the flow rate of the coolant.

[0073] The coolant storage unit may be a cartridge type. Alternatively, the coolant storage unit may be in the form of a large coolant tank. When the coolant storage unit is in the form of a coolant tank, the coolant storage unit may further include a coolant transfer unit that transfers the coolant toward the main body. For example, the coolant transfer unit may be in the form of a hose.

[0074] The cooling device may include a filter module for filtering impurities in the coolant discharged from the coolant storage unit. For example, the filter module may include a filter, a receiving member for receiving the filter, and at least one sealing member for preventing the coolant from leaking between other members connected to the filter module.

[0075] The filter module can be installed in the main body in any manner. For example, the filter module can be arranged between the coolant storage unit and the main body. The filter module can also include a perforating member for perforating the coolant storage unit, so that when the filter module is arranged (or installed) between the coolant storage unit and the main body, the coolant storage unit is perforated to release the coolant. For example, the filter module may include a through hole that accommodates the coolant discharged from the coolant storage unit and transfers it to the main body. The coolant discharged from the coolant storage unit can be input into the main body via the filter module.

[0076] According to the conventional technology, a filter for filtering impurities from a coolant generally corresponds to the shape and size of a housing unit in which the filter is housed. Specifically, when the housing unit of the filter has a circular shape, the filter is selected and used as a product having a circular shape. Thus, if the shape of the filter corresponds to the shape of the housing unit for the filter, there is a possibility that the coolant flowing into the filter may leak to the outside of the filter without distinction within all angle ranges, and in this case, it is found that the leakage amount of the coolant stored in the coolant storage unit (e.g., a cartridge) is relatively large.

[0077] The filter module according to an exemplary embodiment of the present disclosure is designed to have a shape that minimizes coolant leakage. In one example, the filter disclosed in the present disclosure may be provided with a shape different from the shape of the filter containing member. In another example, the sealing member disclosed in the present disclosure may be provided with a shape that seals an opening (e.g., an inlet of a housing) of a coolant storage unit so as to reduce external leakage of the coolant discharged from the coolant storage unit.

[0078] Next, we will refer to Figures 3 to 16 The filter module that can be used in various types of cooling devices as described above is described in detail. Figures 3 to 11 , describes a filter module according to a first exemplary embodiment of the present disclosure, the filter module including a filter having a shape that minimizes leakage of a coolant, and a filter receiving member that maximizes a sealing effect while receiving the filter. In addition, referring to Figures 12 to 16 , describes a filter module including a sealing member having a shape that minimizes leakage of a coolant according to a second exemplary embodiment of the present disclosure.

[0079] See also Figure 3 and Figure 4 . Figure 3 is a view showing a filter module according to a first exemplary embodiment of the present disclosure. Figure 4 is an exploded view of a filter module according to a first exemplary embodiment of the present disclosure.

[0080] According to an exemplary embodiment of the present disclosure, the filter module 1000 may include a filter accommodating member 1100 , a first sealing member 1200 , a second sealing member 1300 , and a filter 1400 .

[0081] The filter receiving member 1100 may include a support surface 1110 , a receiving surface 1120 , and a perforated member 1130 .

[0082] The support surface 1110 may be formed in a plate shape. For example, the support surface 1110 may be formed in a circular plate shape. The support surface 1110 may perform a function of supporting the filter 1400 accommodated in the filter accommodation member 1100 .

[0083] The accommodation surface 1120 may be located at an edge of the support surface 1110 and may protrude in the first direction relative to the support surface 1110. The accommodation surface 1120 may perform a function of accommodating the first sealing member 1200 and / or the filter 1400.

[0084] The perforated member 1130 may be located at the center of the support surface 1110. In addition, the perforated member 1130 may protrude in a second direction relative to the support surface 1110. At this time, the second direction may be opposite to the first direction in which the accommodating surface 1120 extends relative to the support surface 1110. The perforated member 1130 may perform the function of inserting the second sealing member 1300 and perforating the coolant storage unit (e.g., a cartridge). In addition, the perforated member 1130 has a flow path formed therein, and may perform the function of outputting the coolant discharged from the perforated coolant storage unit (e.g., a cartridge) toward the filter 1400 of the filter module 1000 through the flow path formed therein.

[0085] The filter module 1000 according to the exemplary embodiment of the present disclosure may include at least one sealing member that performs a function of preventing coolant leakage. Specifically, the filter module 1000 may include a first sealing member 1200 and / or a second sealing member 1300 .

[0086] As an example, the first sealing member 1200 can perform a function of preventing leakage of the coolant flowing into the main body. To this end, the first sealing member 1200 can be arranged between the main body and the filter module 1000. Specifically, the first sealing member 1200 can be arranged between the main body and the support surface 1110 of the filter module 1000. Alternatively, the first sealing member 1200 can be arranged between the main body and the filter 1400 of the filter module 1000. In addition, the first sealing member 1200 can be accommodated in the accommodating surface 1120 of the filter accommodating member 1100. That is, the first sealing member 1200 can be accommodated in the accommodating surface 1120 extending in the first direction relative to the support surface 1110. Through this structure, the first sealing member 1200 can perform a function of reducing the leakage of the coolant flowing from the filter module 1000 to the main body of the cooling device.

[0087] For example, the second sealing member 1300 can perform a function of preventing leakage of the coolant discharged from the coolant storage unit. To this end, the second sealing member 1300 can be arranged between the coolant storage unit and the filter module 1000. That is, the second sealing member 1300 can be arranged in the second direction relative to the support surface 1110. For a specific example, the filter module 1000 may include a perforated member 1130, which extends in the second direction relative to the support surface 1110. At this time, the second sealing member 1300 may include a through hole having a width greater than the width defined by the perforated member 1130. Specifically, the inner diameter of the second sealing member 1300 defined by the through hole of the second sealing member 1300 may be greater than the outer diameter of the perforated member 1130. At this time, by fitting the through hole of the second sealing member 1300 into the perforated member 1130, the second sealing member 1300 can be coupled to the filter accommodating member 1100. Through this structure, the second sealing member 1200 may perform a function of reducing leakage of coolant flowing from a coolant storage unit (eg, a cylinder or a coolant tank) to the outer surface of the perforating member 1130 through a flow path formed inside the perforating member 1130 .

[0088] Meanwhile, the first sealing member 1200 may include a hollow hole through which the coolant may flow. For example, a hollow hole, ie, a channel through which the coolant may flow, may be formed at the center of the first sealing member 1200.

[0089] In addition, the first sealing member 1200 may be composed of polytetrafluoroethylene or nylon 6 (nylon 6,6). The second sealing member 1200 may also be composed of polytetrafluoroethylene or nylon 6 (nylon 6,6).

[0090] The filter 1400 may be disposed in the filter receiving member 1100. As an example, the filter 1400 may be disposed between the filter module 1000 and the main body. At this time, the filter 1400 may be used to filter out impurities contained in the coolant flowing from the filter module 1000 to the main body. As a specific example, the filter 1400 may be disposed between the support surface 1110 and the first sealing member 1200. At this time, the filter 1400 may be used to filter out impurities contained in the coolant flowing from the support surface 1110 to the first sealing member 1200. Figures 6 to 11 The shape and structure of the filter 1400 are described in detail.

[0091] The filter 1400 may be made of various materials. For example, the filter 1400 may be made of various materials including paper, metal, synthetic fiber, or polymer compounds.

[0092] When the cooling device is used, the filter 1400 may be disposable, and in this case, the material of the filter 1400 may include paper. By manufacturing the filter 1400 with a paper material, the manufacturing cost of the filter 1400 may be relatively reduced, and since the filter 1400 must be replaced each time the cooling device is used, the product manufacturing cost or the post-management cost may be reduced. When the filter 1400 is to be reused rather than used once, the material of the filter 1400 may include a material other than a paper material.

[0093] The filter 1400 may be implemented in the form of a mesh net. For example, the filter 1400 may be in the form of a net including a plurality of holes having a predetermined size.

[0094] The filter 1400 may be implemented in various shapes. For example, the filter 1400 may be implemented in a disc shape having a predetermined diameter and a circular cross section, or in a disc shape having a predetermined width and a square cross section. For another example, the filter 1400 may be implemented in a convex shape, as described below.

[0095] Meanwhile, the filter module 1000 according to the exemplary embodiment of the present disclosure may further include a gripping unit. The gripping unit may include at least one gripping member. At least one gripping member may be accommodated in the connecting member of the main body. For example, a groove corresponding to the shape of the gripping member may be formed in the connecting member of the main body, and the filter module 1000 may be mounted on the main body by accommodating the gripping member in the groove formed in the connecting member of the main body. The filter module 1000 may be accommodated in the connecting member of the main body by the gripping member, and the coolant storage unit may be more easily perforated by the perforating member 1130 of the filter module 1000 by being fastened to the connecting part of the main body accommodating the filter module 1000, as described below.

[0096] See also Figure 5 . Figure 5 1 is a view for explaining an aspect in which a first sealing member is accommodated in a filter accommodating member according to a first exemplary embodiment of the present disclosure.

[0097] The first sealing member 1200 may have a size corresponding to the width defined by the receiving surface 1120. Here, the width defined by the receiving surface 1120 may refer to the diameter of the shape defined by the receiving surface 1110. Specifically, the width defined by the receiving surface 1120 may be the length of the longest part of the shape defined by the receiving surface 1120. For example, when the shape defined by the receiving surface 1120 is a circle, the width defined by the receiving surface 1110 may be a diameter. In another example, when the shape defined by the receiving surface 1120 is a quadrilateral, the width defined by the receiving surface 1120 may be a diagonal line. In a specific example, the shape defined by the receiving surface 1120 may be a circle. In this case, the width defined by the receiving surface 1120 may be the diameter D3 of the circular shape defined by the receiving surface 1120. The first sealing member 1200 according to an exemplary embodiment of the present disclosure may have an outer diameter D4 that is smaller than or less than the width D3 defined by the receiving surface 1120.

[0098] In addition, the first sealing member 1200 may have a shape corresponding to the shape of the receiving surface 1120. For example, when the shape defined by the receiving surface 1120 is a circle, the first sealing member 1200 may be provided as a circle corresponding to the shape defined by the receiving surface 1120. For example, when the shape defined by the receiving surface 1120 is a quadrilateral, the first sealing member 1200 may be provided as a quadrilateral corresponding to the shape defined by the receiving surface 1120.

[0099] Through this, at least a portion of the first sealing member 1200 may be received in the filter receiving member 1100 through the receiving surface 1120 .

[0100] However, Figure 5 The shape and size of the receiving surface and the shape and size of the first sealing member shown are merely examples and can be transformed into structures having any suitable shape and size to achieve the purpose of the filter module filtering out impurities in the coolant discharged from the coolant storage unit and preventing coolant leakage while outputting the filtered coolant toward the main body.

[0101] As described above, the second sealing member 1300 according to the exemplary embodiment of the present disclosure may be fitted into the perforated member 1130 of the filter receiving member 1100. Referring again to Figure 4, the second sealing member 1300 may include a through hole formed in the center of the second sealing member 1300. In this case, the width D2 of the through hole of the second sealing member 1300 may be greater than or equal to the width D1 defined by the perforated member 1130. Through this, the second sealing member 1300 may be fitted into the perforated member 1130 of the filter receiving member 1100, and leakage of the coolant flowing from the coolant storage unit (e.g., a cartridge or a coolant tank) into the inner flow path of the perforated member 1130 to the outer surface of the perforated member 1130 may be reduced.

[0102] In addition, the height (or thickness, L2) of the second sealing member 1300 may be less than the length L1 of the perforated member 1130. By this, even when the second sealing member 1300 is fitted into the perforated member 1130, the perforated member 1130 may protrude to the outside of the second sealing member 1300. Therefore, a structure may be provided in which the perforated member 1130 protruding outwardly perforates the coolant storage unit (e.g., a hose connected to a cartridge or a coolant tank). In addition, the coolant discharged from the coolant storage unit may flow into the filter 1400 disposed in the filter receiving member 1110.

[0103] The filter may have the same shape as the support surface 1110 .

[0104] According to an exemplary embodiment of the present disclosure, the filter 1400 may have a shape different from that of the support surface 1110 .

[0105] Next, we will refer to Figures 6 to 9 The shape and characteristics of the filter 1400 according to an exemplary embodiment of the present disclosure are described in detail.

[0106] See also Figure 6 . Figure 6 1 is a view showing an aspect in which the filter 1400 according to the first exemplary embodiment of the present disclosure is accommodated in the filter accommodating member 1110 .

[0107] The filter 1400 according to an exemplary embodiment of the present disclosure may be disposed in the filter receiving member 1100. At this time, the filter 1400 may receive the coolant flowing in from the flow path formed in the perforated member 1130 and filter out impurities in the received coolant, thereby ensuring the safety of the cooling device.

[0108] According to an exemplary embodiment of the present disclosure, the filter 1400 may have a shape different from the shape defined by the accommodation surface 1120, so that when the filter 1400 is disposed on the filter accommodation member 1100, the first sealing member 1200 has a contact surface with the support surface 1100. In addition, even when the filter 1400 is disposed in the filter accommodation member 1100, the filter 1400 may have a shape having an area S1 smaller than an area S2 defined by the accommodation surface 1120, so that the first sealing member 1200 may have a contact surface with the support surface 1100. Therefore, since the contact surface between the first sealing member 1200 and the support surface 1100 is increased, leakage of the coolant may be further prevented.

[0109] For a more specific example, the filter 1400 may be implemented in the form of a protruding portion including a central portion and at least one foot, so that even when the filter 1400 is disposed in the filter receiving member 1100, the first sealing member 1200 may have a contact surface with the support surface 1110. A detailed description of this will be provided by Figure 7 and Figure 8 This type of filter 1400 forms a contact surface between the first sealing member 1200 and the support surface 1110 at a radial position relative to the central surface of the filter 1400, thereby preventing leakage of the coolant.

[0110] According to an exemplary embodiment of the present disclosure, the filter 1400 can be configured to have a structure with any suitable shape and size, so that when the filter 1400 is set in the filter receiving member 1100, the filter 1400 is set to correspond to the flow path formed in the perforated member 1130. For example, the width of the central portion of the filter 1400 can be greater than the width of the flow path formed in the perforated member 1130. For example, the width of the central portion of the filter 1400 can be less than the width of the shape defined by the receiving surface 1120. In addition, when the filter 1400 is set on the filter receiving member 1100, at least one foot of the protruding portion of the filter 1400 can contact the receiving surface 1120, so that the movement of the filter 1400 can be limited. Fig. 9 In this type of filter 1400, when the filter 1400 is set on the filter receiving member 1100, the central portion of the filter 1400 is located at a position corresponding to the flow path of the perforated member 1130, and the filter 1400 is prevented from shaking, so that impurities contained in the coolant flowing out of the flow path of the perforated member 1130 can be removed by the filter 1400.

[0111] Next, we will refer to Figure 7 and Figure 8Features of the shape and size of the filter 1400 according to various exemplary embodiments of the present disclosure are described in detail. Figure 7 14 are views illustrating various shapes of the filter 1400 according to the first exemplary embodiment of the present disclosure. Figure 8 14 is a view for explaining the shape of the filter 1400 according to the first exemplary embodiment of the present disclosure in more detail.

[0112] The filter 1400 according to an exemplary embodiment of the present disclosure may have a shape including a central portion 1410 and at least one protrusion portion 1420 extending outward from the central portion 1410 .

[0113] The central portion 1410 of the filter 1400 may have a shape corresponding to the shape defined by the receiving surface 1120. For example, the shape defined by the receiving surface 1120 may be a circle. At this time, the central portion 1410 of the filter 1400 may be provided in a circle.

[0114] The area of ​​the central portion 1410 of the filter 1400 may be smaller than the area of ​​the shape defined by the receiving surface 1220. By this, even when the filter 1400 is disposed in the filter receiving member 1100 as described above, the first sealing member 1200 may have a contact surface with the support surface 1110.

[0115] On the other hand, the area of ​​the central portion 1410 of the filter 1400 may be greater than or equal to the area of ​​the shape defined by the perforated member 1130. Through this, the filter 1400 may receive the coolant flowing out of the flow path formed in the perforated member 1130 and filter out impurities in the coolant.

[0116] The protruding portion 1420 of the filter 1400 may include N feet. As used herein, a foot may include any structure having any shape and length extending outward from the central portion 1410 of the filter 1400.

[0117] The protruding portion 1420 of the filter 1400 according to an exemplary embodiment of the present disclosure may include two or more feet, including a first foot 1422 and a second foot 1424. For example, the protruding portion 1420 of the filter 1400 may include 2 or more, but 10 or less feet. In another example, the protruding portion 1420 of the filter 1400 may include 2 or more, but 8 or less feet. In another example, the protruding portion 1420 of the filter 1400 may include 2 or more, and 6 or less feet.

[0118] Meanwhile, a plurality of legs of the protruding portion 1420 of the filter 1400 according to an exemplary embodiment of the present disclosure may be symmetrically formed with respect to the central portion 1410 of the filter 1400 .

[0119] The first leg 1422 may extend from a first inner end IE1 connected to the central portion 1410 to a first outer end EE1 not connected to the central portion 1410. Similarly, the second leg 1424 may extend from a second inner end IE2 connected to the central portion 1410 to a second outer end EE2 not connected to the central portion 1410. At this time, the second outer end EE2 and the first outer end EE1 of the first leg may be spaced apart from each other. Here, the inner end may refer to an end included in any region adjacent to or connected to the central portion of the protruding portion containing the filter. In addition, the outer end may refer to an end farthest from the central portion containing the protruding portion.

[0120] The filter 1400 according to the exemplary embodiment of the present disclosure may be formed into a structure in which the spacing distance ( EE1 ) between the first outer end EE1 of the first leg 1422 and the second outer end EE2 of the second leg 1424 is Figure 8 L3) is larger than the width of the center part ( Figure 8 With the filter 1400 of this shape, since the protruding portion 1420 of the filter 1400 can be in contact and shake less, the anti-leakage effect of the coolant can be increased.

[0121] In addition, the first leg 1422 may have a shape in which the length of the first inner end IE1 ( Figure 8 The width L5) is greater than the width of the area adjacent to the first outer end EE1 ( Figure 8 L6). Similarly, the second leg 1424 can have a shape in which the length of the second inner end IE2 is greater than the width of the area adjacent to the second outer end EE2. In other words, the first leg 1422 and / or the second leg 1424 can have a shape that becomes thinner and thinner from the central portion 1410 to the outside. With this shape, the filter 1400 can have an area smaller than the area of ​​the shape defined by the accommodating surface 1120. In addition, when the filter 1400 is arranged between the first sealing member 1200 and the supporting surface 1110, a contact surface can be formed where the first sealing member 1200 contacts the supporting surface 1110. Therefore, the area of ​​the outside of the filter 1400 sealed by the first sealing member 1200 is increased, thereby providing an effect of minimizing the leakage of the coolant.

[0122] See also Fig. 9 . Fig. 9 14 is a view for explaining the shape of the filter 1400 according to the first exemplary embodiment of the present disclosure in more detail.

[0123] As described above, the filter 1400 may include the central portion 1410 and at least one protrusion 1420 extending outward from the central portion 1410. At this time, the protrusion 1420 may include a first leg 1422 and a second leg 1424.

[0124] Here, the spacing distance L6 between the first outer end EE1 of the first leg 1422 and the second outer end EE2 of the second leg 1424 may be greater than or equal to the width L5 of the shape defined by the receiving surface 1120. By this, when the filter 1400 is disposed in the filter receiving member 1100 (for example, when disposed between the first sealing member 1200 and the support surface 1120), each of the first outer end EE1 of the first leg 1422 and the second outer end EE2 of the second leg 1424 may contact the inner surface of the receiving surface 1120. Therefore, when the filter 1400 is disposed in the filter receiving member 1110, the central portion 1410 of the filter 1400 is located at a position corresponding to the position of the coolant flow path forming the perforated member 1130, and the movement of the filter may be restricted. This allows filtering out impurities in the coolant flowing in through the perforated member 1130 while minimizing the leakage of the coolant.

[0125] Due to the structure of the filter module 1000 and the shape of the filter 1400 described above, the filter module 1000 according to the exemplary embodiment of the present disclosure has a contact surface between the first sealing member 1200 and the support surface 1110. Therefore, the first sealing member 1200 can seal the outside of the filter 1400 and prevent the coolant from leaking to the outside through the filter 1400.

[0126] Next, we will refer to Fig.10 and Fig.11 An experiment is described in detail to demonstrate the coolant leakage prevention effect of the filter module 1000 including the filter 1400 according to an exemplary embodiment of the present disclosure.

[0127] <Comparative experiment of coolant leakage>

[0128] <Experimental example>

[0129] As an experimental example, a cartridge equipped with a filter module 1000 was prepared, in which a filter 1400 was disposed in a filter receiving member 1100 according to an exemplary embodiment of the present disclosure. Specifically, a filter module 1000 was used in which a filter having five legs was disposed in the filter receiving member 1100. For the experimental group, a coolant leakage experiment was performed on cartridges of two different capacities (74 grams and 45 grams).

[0130] <Comparative Example>

[0131] As a comparative example, a cartridge equipped with a filter module 1000 was prepared in which a circular filter was provided in a filter receiving member 1100. Specifically, a circular filter was used, the area of ​​which was substantially equal to the area defined by the receiving surface 1120 of the filter receiving member 1100. For the comparative group, a coolant leakage experiment was conducted on a 74 g cartridge.

[0132] <Experimental methods>

[0133] The weight of the cartridge over time was measured by applying the same tightening force to the cartridges equipped with the filter modules prepared according to the comparative example and the experimental example, respectively. In addition, the coolant consumption of the cartridge, ie, the coolant leakage, was measured based on the initial cartridge weight and the cartridge weight over time.

[0134] <Experimental Results>

[0135] Fig.10 is a table showing the results of the coolant leakage test. Fig.10 , when the circular filter is set in the filter module 1000, the weight of the cartridge is initially measured as 74 grams, but when 24 hours have passed, the weight of the cartridge is measured as 0 grams. That is, after 24 hours, in the case of the circular filter, the coolant stored in the cartridge is completely consumed.

[0136] On the other hand, when a filter including a plurality of feet is provided in the filter module 1000 according to the exemplary embodiment of the present disclosure, the weight of the cartridge is initially measured to be 74 grams, 73.0 grams after 24 hours have passed, 72.6 grams after 48 hours have passed, 72.4 grams after 72 hours have passed, and 72.3 grams after 96 hours have passed. In other words, in the case where the filter has a plurality of feet, it has been confirmed that the coolant stored in the cartridge leaks less than 1 gram even after 96 hours have passed.

[0137] Furthermore, even when the experiment was conducted on a cartridge of other weight (45 g), the weight of the cartridge was measured to be 44.8 g after 24 hours, 42.8 g after 48 hours, 36.6 g after 72 hours, and 33.8 g after 96 hours. In other words, in the case of the filter having a plurality of legs, it was confirmed that less than 5% of the coolant stored in the cartridge leaked even after 96 hours.

[0138] Through the results of this experiment, it can be demonstrated that, compared with the use of a conventional circular filter, when the filter according to the exemplary embodiment of the present disclosure is used, the effect of preventing coolant leakage is significantly improved.

[0139] <Experimental Analysis>

[0140] See also Fig.11 . Fig.11 The figure schematically shows the leakage path of the coolant to explain Fig.10 The reason for the significant difference in the results of the coolant leakage comparison experiment.

[0141] In the case of the comparative example, that is, when the conventional circular filter is accommodated in the filter accommodation member 1100, the first sealing member 1200 does not have a contact surface with the support surface 1110, and thus the sealing effect of the first sealing member 1200 on the outer area of ​​the circular filter may be significantly reduced. Therefore, for all angle ranges, the coolant may leak through the filter to the outside of the filter module 1000.

[0142] On the other hand, in the case of the experimental example, that is, when the filter 1400 having a plurality of legs is accommodated in the filter accommodation member 1100 according to the exemplary embodiment of the present disclosure, the first sealing member 1200 has a contact surface S3 with the support surface 1110, so that the first sealing member 1200 can seal the outer area of ​​the filter 1400. Therefore, the possibility of the coolant leaking to the outside of the filter module 1000 through the filter is greatly reduced.

[0143] At the same time, reference Fig.11 , the receiving surface 1120 is formed only on a portion of the edge of the supporting surface 1110. In this case, it may be more advantageous that at least one foot of the protruding portion 1420 of the filter 1400 including the first foot 1422 and the second foot 1424 may contact the receiving surface to limit the movement of the filter and position the central portion of the filter to correspond to the flow path of the perforated member.

[0144] exist Figures 3 to 11 In the description, the filter module is mainly described in which a filter including a plurality of feet is accommodated. Figures 3 to 11 The shape of the filter or the structure of the filter module shown in is only an example for the convenience of explanation, and a filter and a filter module are provided, and the filter and the filter module are transformed into a suitable structure to filter out impurities in the coolant, while preventing external leakage of the coolant by increasing the contact area between the first sealing member 1200 and the support surface 1110, and the scope of rights of the present disclosure should be determined by the interpretation of the claims herein.

[0145] Next, we will refer to Figures 12 to 16 The filter module 2000 according to the second exemplary embodiment of the present disclosure is described in detail. In this exemplary embodiment, the characteristics of the shape and size of the second sealing member 2300 that improves the leakage prevention effect of the coolant are mainly described. Since the contents of the above-mentioned filter receiving member 1100, the first sealing member 1200 and the filter 1400 can be applied in the same manner, the repeated contents will be omitted.

[0146] See also Fig.12 and Fig.13 . Fig.12 is a view showing a filter module according to a second exemplary embodiment of the present disclosure. Fig.13 is an exploded view of a filter module according to a second exemplary embodiment of the present disclosure.

[0147] The filter module 2000 according to the second exemplary embodiment of the present disclosure may include a filter accommodating member 2100, a first sealing member 2200, a second sealing member 2300 and a filter 2400. Here, the content of the filter accommodating member 1100 of the filter module 1000 according to the above-mentioned first exemplary embodiment can also be applied to the filter accommodating member 2100. In addition, the content of the first sealing member 1200 of the filter module 1000 according to the above-mentioned first exemplary embodiment can also be applied to the first sealing member 2200. In addition, the content of the filter 1400 of the filter module 1000 according to the above-mentioned first exemplary embodiment can also be applied to the filter 2400. At the same time, in this exemplary embodiment, a filter having the same shape as the shape (e.g., circular) defined by the accommodating surface can also be used.

[0148] The content of the second sealing member 1300 according to the first exemplary embodiment described above can be inferred and applied to the second sealing member 2300 of the filter module 2000 according to the second exemplary embodiment of the present disclosure. However, the size and shape of the second sealing member 2300 according to the second exemplary embodiment of the present disclosure may be different from the second sealing member 1300 according to the first exemplary embodiment described above.

[0149] Specifically, the outer diameter D5 of the second sealing member 2300 may have a shape smaller than the outer diameter D4 of the first sealing member 2200. When the perforating member 2130 perforates the coolant storage unit (e.g., a cartridge) as described below, this can improve the sealing effect of the inlet of the cartridge housing by easily transforming the second sealing member 2300 to an outer diameter corresponding to the width defined by the inlet of the cartridge housing.

[0150] Next, we will refer to Figures 14 to 16 The connection relationship between the second sealing member 2300 and the coolant storage unit according to this exemplary embodiment is described in detail. The following will focus on the barrel-type coolant storage unit. However, this is only for the convenience of explanation, and in order that even when the second sealing member 2300 is connected to the coolant transfer unit (e.g., hose) of the coolant tank-type coolant storage unit, the second sealing member 2300 has an outer diameter corresponding to the width of the coolant transfer unit (e.g., hose), the second sealing member 2300 can have any suitable shape and size.

[0151] Fig.142 is a view showing a cross section of the second sealing member 2300 and the barrel after the barrel and the body are fastened according to the second exemplary embodiment. Specifically, Fig.14 a is a view showing a cross section of the second sealing member 2300 and the cartridge when the cartridge begins to be fastened with the body. Fig.14 b is a view showing a cross section of the second sealing member 2300 and the cartridge when the cartridge is completely fastened to the body.

[0152] The cartridge may include a housing in which a coolant is stored and a cover that seals the coolant and is disposed adjacent to an inlet of the housing. The housing may be provided in a form that can accommodate the cover.

[0153] Here, the cover can be implemented as a material perforated by a perforating member as described below. For example, the material of the cover can be brass or stainless steel.

[0154] The barrel may also include a rubber member in the area between the sealing cover and the housing, and the housing may be configured to accommodate the rubber member. At the same time, a coupling member may be formed on the outer surface of the housing, and the coupling member may be fastened to a connecting member formed on the main body of the cooling device. For example, the coupling member and the connecting member are both configured with corresponding threaded lines, so that the barrel and the main body can be fastened by screwing the barrel onto the main body. At this time, the filter module 2000 is arranged between the barrel and the main body, filters out impurities in the coolant discharged from the barrel, and outputs the coolant from which the impurities have been filtered out to the main body.

[0155] The second sealing member 2300 according to this exemplary embodiment can have a width corresponding to the entrance of the cartridge housing. The second sealing member 2300 can have a width greater than the entrance of the cartridge housing by a predetermined length, so as to fit into the entrance of the cartridge housing. Preferably, the predetermined length can be 2.5 millimeters or less. More preferably, the predetermined length can be 1.5 millimeters or less. More preferably, the predetermined length can be 0.8 millimeter or less. More preferably, the predetermined length can be 0.5 millimeter or less.

[0156] As described above, before the cartridge and the body are completely fastened, the second sealing member 2300 may have a shape having a first outer diameter D5. On the other hand, when the cartridge and the body are completely fastened, the perforating member 2130 of the filter module 2000 may perforate the cartridge cover. At this time, the second sealing member 2300 may receive Fig.15In the pressure as described below, the second sealing member 2300 can be transformed into a shape with a second outer diameter D6 corresponding to the width R1 of the entrance of the barrel housing, and inserted into the barrel housing. In this case, the second outer diameter D6 can be less than the first outer diameter D5. In addition, the second sealing member 2300 inserted into the inside of the barrel housing can contact or press the cover contained in the housing. Through this, the second sealing member 2300 can relatively firmly seal the entrance of the housing, and can minimize the amount of coolant discharged from the barrel to the outside through the outer surface of the perforated member 2130. At the same time, the cover contained in the housing can be pushed into or transformed into the housing by being pressed by the second sealing member 2300.

[0157] According to the shape and size defined by the inlet of the shell of the barrel, the size and shape of the second sealing member 2300 can be appropriately selected or transformed. At the same time, the first outer diameter D5 can be greater than the width R1 of the inlet of the barrel shell, and specifically, the first outer diameter D5 can be 0-20%, 0-10% or 0-5% larger than the width R1 of the inlet of the barrel shell. As described below, when the body and the barrel are tightened, the second sealing member 2300 can be transformed and can be contracted and inserted into the inlet of the barrel shell. In addition, the second sealing member 2300 inserted into the interior of the barrel shell through the inlet of the barrel shell is inserted into the barrel shell through the inlet of the barrel shell. Fig.15 The pressure applied in the third direction can be contracted in the third direction and expanded in the fourth direction at the same time, so that the sealing surface can be further constructed on the inner surface of the inlet of the cartridge housing and the sealing of the inlet of the cartridge housing is strengthened.

[0158] See also Fig.15 . Fig.15 It is a view for explaining a principle that the outer diameter of the second sealing member according to the second exemplary embodiment changes as the cylinder and the body are fastened.

[0159] When the coupling member of the tube and the connecting member of the main body are fully fastened, the filter module 2000 can be arranged between the tube and the main body. In addition, when the filter module 2000 is arranged between the tube and the main body, the thickness of the second sealing member 2300 can be greater than the spacing distance between the support surface 2110 and one end of the tube. Therefore, when the second sealing member 2300 is subjected to the pressure P of the support surface 2110 in the third direction perpendicular to the support surface 2110, at least a portion of the second sealing member 2300 can be inserted into the entrance of the tube housing. For example, when the main body and the tube are fastened, the first outer diameter D5 of the second sealing member 2300 and the width R1 of the entrance of the tube housing that do not correspond to the part can be cut by the tube housing, and can not be inserted in the tube housing, and the remaining part can be inserted into the inside of the tube housing. In addition, after the second sealing member 2300 is inserted into the inside of the tube housing, the second sealing member 2300 can be transformed into a shape with an outer diameter D6 corresponding to the width R1 defined by the entrance of the housing. In addition, by the pressure applied in the third direction, the thickness of the second sealing member 2300 inserted into the entrance of the cartridge housing and arranged between the entrance of the cartridge housing and the cover is reduced in the third direction and expanded in the fourth direction perpendicular to the third direction. Therefore, the second sealing member can form a sealing surface with the cartridge housing in addition not only in the third direction but also in the fourth direction.

[0160] That is, the second sealing member 2300 may expand in the fourth direction and then seal the inner surface of the cartridge case.

[0161] In this case, the second sealing member 2300 may be made of a material having a positive Poisson's ratio and may be made of a material having a yield stress of 50 MPa or less, more specifically 30 MPa or less, more specifically 20 MPa or less, and more specifically 5 MPa to 20 MPa.

[0162] At the same time, when the coupling member of the barrel is completely fastened with the connecting member of the main body, the perforated member 2130 of the filter module 2000 can be inserted into the inside of the barrel housing, and then the cover is perforated. Specifically, as described above, since the length of the perforated member 2130 is greater than the thickness (or height) of the second sealing member 2300, the perforated member 2130 can protrude to the outside and perforate the cover. Therefore, the coolant stored in the barrel can flow into the filter module 2000 through the perforated member 2130. At this time, since the second sealing member 2300 can relatively tightly seal the inlet of the housing of the barrel, the amount of the coolant leaking to the outside from the barrel through the outer surface of the perforated member 2130 can be significantly reduced.

[0163] In the following, reference is made to Fig.16, an experiment will be described in detail below to demonstrate the coolant leakage prevention effect of the filter module 2000 including the second sealing member 2300 according to the present exemplary embodiment.

[0164] <Comparative test of coolant leakage>

[0165] <Experimental example>

[0166] As an experimental example, a cartridge equipped with a filter module 2000 was prepared in which a second sealing member 2300 and a filter 2400 having a plurality of legs according to an exemplary embodiment of the present disclosure were disposed in a filter receiving member 2100. Specifically, a filter module 2000 was used in which a filter having five legs, a first sealing member 2200 having an outer diameter of about 9.3 mm, and a second sealing member 2300 having an outer diameter of about 5.6 mm were disposed in a filter receiving member 2100. For the experimental group, a coolant leakage experiment was conducted using a cartridge containing 74 g of coolant.

[0167] <Comparative Example>

[0168] As a comparative example, a cartridge equipped with a filter module 2000 was prepared, in which a circular filter, a first sealing member having an outer diameter of about 9.3 mm, and a second sealing member having an outer diameter of about 9.3 mm were disposed in the filter accommodation node member 2100. Specifically, a circular filter having an area substantially the same as that defined by the accommodation surface 2120 of the filter accommodation member 2100 was used, and the second sealing member sealed the cartridge by forming a contact surface with the inlet of the cartridge housing without being inserted into the interior of the cartridge housing even when the cartridge was fastened to the body. For the comparative group, a coolant leakage experiment was also conducted using a cartridge containing 74 g of coolant.

[0169] <Experimental methods>

[0170] The weight of the cartridge over time was measured by applying the same fastening force to the cartridges equipped with the filter modules prepared according to the comparative example and the experimental example. In addition, the coolant consumption of the cartridge, ie, the coolant leakage, was measured based on the initial cartridge weight and the cartridge weight over time.

[0171] <Experimental Results>

[0172] Fig.16 is a table showing the results of the coolant leakage test. Fig.16 In the case of the control group, the weight of the cylinder was initially measured to be 74 g, but the weight of the cylinder was measured to be 0 g after 8 hours. That is, it was confirmed that the coolant stored in the cylinder in the control group was completely consumed after 8 hours.

[0173] On the other hand, in the case of the experimental group, the weight of the cartridge was initially measured to be 74 g, and even after 72 hours, the weight of the cartridge was measured to be 68.7 g only for one experiment, while in the other experiments, the weight of the cartridge was measured to be 74 g. In other words, in the case of the experimental example, it was confirmed that the coolant stored in the cartridge had almost no leakage even after 72 hours.

[0174] Through the results of this experiment, it can be proved that when the second sealing member 2300 according to the exemplary embodiment of the present disclosure is used, the effect of preventing the coolant leakage is greatly improved.

[0175] <Experimental Analysis>

[0176] In the case of the comparative example, the sealing member is not inserted into the interior of the barrel housing, but seals the coolant by making surface contact with the outer surface of the housing. At the same time, the sealing pressure that can indicate the sealing performance is defined as the force applied to the contact surface per unit contact cross-sectional area. At this time, in the case of sealing by surface contact, the sealing pressure varies according to the contact cross-sectional area. Specifically, as the contact cross-sectional area increases, the sealing pressure decreases, so the sealing performance decreases, and the possibility of coolant leakage increases. In addition, in the case of surface contact, there is a disadvantage that the sealing performance becomes irregular depending on the type of barrel or the surface condition of the barrel. Due to these factors, in the case of the comparative example, it is expected that the leakage of the coolant will be carried out in a short time.

[0177] On the other hand, in the case of the experimental example, the second sealing member is transformed into a form that blocks the entire inlet of the barrel housing. Therefore, the possibility of coolant leakage is significantly reduced. In addition, as in the experimental example, when the sealing member is inserted into the interior of the housing for sealing, it has the advantage of providing a high sealing effect regardless of the surface of the barrel and the inner surface of the housing. Through this, it can be expected that in the case of the experimental example, the coolant will hardly leak.

[0178] In addition, in the case of the experimental example, even if the fastening force is relatively weak, it is possible to prevent the coolant flowing from the cover of the barrel into the perforated member from leaking. Specifically, in the case of a comparative example in which the sealing member performs a sealing function by contacting the surface of the "outer surface" of the barrel housing, a relatively strong fastening force, such as a force of 2500 Nm or more, specifically, a fastening force in the range of 2500 Nm to 3500 Nm, cannot prevent the coolant discharged from the barrel from leaking to the outside. In addition, when a strong fastening force in the range of 2500 Nm to 3500 Nm is applied to the cooling device, the durability of the cooling device may be greatly affected in terms of applying a strong force to the cooling device. For example, when a strong fastening force in the range of 2500 Nm to 3500 Nm is applied to the cooling device, the cooling device or a component in the cooling device may be damaged.

[0179] On the other hand, the second sealing member 2300 according to the second exemplary embodiment of the present disclosure can prevent the coolant from leaking from the barrel to the perforated member, even if the fastening force is relatively weak, for example, 2500 Nm or less, specifically, a fastening force in the range of 1600 Nm to 2500 Nm. It is speculated that this is because the second sealing member 2300 is inserted into the barrel housing and seals the inner surface of the entrance of the barrel housing. In other words, according to the experimental example, the advantageous effect of achieving a sealing effect to prevent coolant leakage while maintaining the durability of the cooling device is provided, because a relatively weak fastening force is applied to the cooling device, and the coolant leaking from the barrel to the outside can be minimized.

[0180] exist Figures 12 to 16 In the description, the second sealing member is mainly described, which has a size and shape that can be changed to the outer diameter of the inlet of the insertion barrel housing. However, Figures 12 to 16 The size or shape of the second sealing member shown is only an example for convenience of explanation, and the shape or size of the second sealing member can be appropriately changed to prevent leakage of the coolant discharged from the coolant storage unit. For example, the second sealing member can be provided with a shape having an outer diameter corresponding to the width of the shape defined by the inlet of the cartridge housing while surrounding the outer surface of the perforating member, so that when the perforating member perforates the cover, the second sealing member can be inserted into the cartridge housing without being changed and seals the inlet of the housing.

[0181] Below, reference Fig.17 and Fig.18 , the coupling relationship between the filter module 3000 and the coolant storage unit when the filter module 3000 according to the third exemplary embodiment described above is used will be described in detail. In this case, the coolant storage unit is mainly described as a cartridge type, but this is only for the convenience of description, and the technical concept of the present disclosure is not limited thereto. For example, even when the filter module 3000 is coupled to the coolant transfer unit (e.g., a hose) of the coolant storage unit, the coupling relationship between the filter module 3000 and the cartridge to be described later can also be applied.

[0182] Fig.17 FIG. 2 is a cross-sectional view showing a filter module 3000 and a cartridge according to a third exemplary embodiment after the cartridge and the body of the present disclosure are fastened. Fig.17 In the example, for ease of explanation, the main body is not shown, but it can be understood that the cylinder is connected to the Fig.14 or Fig.15 The subject shown.

[0183] refer to Fig.17, the filter module 3000 according to the third exemplary embodiment of the present disclosure may include a filter accommodating member 3100, a first sealing member 3200, a second sealing member 3300 and a filter. Here, the filter accommodating member 3100 may be implemented similarly to the filter accommodating member 1100 of the filter module 1000 according to the first exemplary embodiment described above or the filter accommodating member 2100 of the filter module 2000 according to the second exemplary embodiment. In addition, the first sealing member 3200 may be implemented similarly to the first sealing member 1200 of the filter module 1000 according to the first exemplary embodiment described above or the first sealing member 2200 of the filter module 2000 according to the second exemplary embodiment. In addition, the contents of the filter 1400 of the filter module 1000 according to the first exemplary embodiment described above or the contents of the filter 2400 of the filter module 2000 according to the second exemplary embodiment may be applied to the filter according to the third exemplary embodiment as well.

[0184] Within the scope not conflicting with the following description, the second sealing member 3300 of the filter module 3000 according to the third exemplary embodiment may be implemented similarly to the second sealing member 1300 of the filter module 1000 according to the first exemplary embodiment or the second sealing member 2300 of the filter module 2000 according to the second exemplary embodiment.

[0185] refer to Fig.18 Before describing in detail the second sealing member 2300 according to the third exemplary embodiment, the structure of the cartridge will be described in more detail.

[0186] Fig.18 It is a view showing the structure of a cartridge according to an exemplary embodiment of the present disclosure.

[0187] refer to Fig.18 , the cartridge may include a housing for storing a coolant, a coupling member formed on an outer surface of the housing, a pressure unit, and a cover inserted into an interior of the housing.

[0188] Since the contents described in other parts of the present disclosure are applicable to the housing, the coupling member, and the cover, the repeated parts may be omitted.

[0189] The pressure unit may refer to a portion that presses the filter module 3000 during the process of coupling the cartridge to the body through the filter module 3000. Since the pressure unit is in sufficiently close contact with the filter module 3000 according to the coupling of the cartridge to the body, leakage of the coolant may be prevented when the cooling device is operated. The pressure unit may include the housing inlet described above.

[0190] refer to Fig.18(b), when the barrel is viewed from the front (FV), each component of the barrel can have any width. Specifically, the width R1 of the housing inlet, the width R2 of the pressure unit, and the width R3 of the portion of the coupling member can be defined in sequence based on the width O1 of the through hole of the narrowest cover.

[0191] Reference again Fig.17 , when the cartridge presses the filter module 3000 as it is fastened to the body, the pressure unit of the cartridge may press the second sealing member 3300 of the filter module 3000. However, unlike the second exemplary embodiment, the second sealing member 3300 of the filter module 3000 is not inserted into the housing of the cartridge. In other words, even in a state where the pressure unit of the housing is pressed against the second sealing member 3300 of the filter module 3000, the perforating member of the filter module 3000 may perforate the cover of the cartridge.

[0192] Since the pressure unit of the cartridge and the second sealing member 3300 of the filter module 3000 are in close contact with each other, leakage of the coolant may be prevented.

[0193] At this time, the second sealing member 3300 can be set according to the size of each component of the barrel. For example, the outer diameter of the second sealing member 3300 can be greater than the width O1 of the through hole of the cover. Alternatively, the outer diameter of the second sealing member 3300 can be greater than the width O1 of the through hole of the cover and less than the width R1 of the housing inlet. Alternatively, the outer diameter of the second sealing member 3300 can be greater than the width R1 of the housing inlet and less than the width R2 of the pressure unit. Alternatively, the outer diameter of the second sealing member 3300 can be greater than the width R2 of the pressure unit and less than the width R3 of the portion of the coupling member. In the third exemplary embodiment, the outer diameter of the second sealing member 3300 is preferably greater than the width R1 of the housing inlet and less than the width R2 of the pressure unit to prevent coolant leakage and facilitate manufacturing.

[0194] Although the above description focuses on the case where the coolant storage unit is a cylinder, the technical concept of this article is not limited to this and can be similarly applied to the following case, that is, the coolant storage unit includes a box for storing coolant and a coolant transfer unit (e.g., a hose) for transferring the coolant, and the coolant transfer unit is connected to the second sealing member 3300 of the filter module 3000.

[0195] Next, we will refer to Fig.19 Describes the secondary filter module.

[0196] The main purpose of the filter modules 1000, 2000, and 3000 of the various exemplary embodiments described above is to prevent impurities included in the coolant from flowing into the main body during the process of the coolant storage unit being coupled to the main body. At the same time, even when the coolant storage unit is not coupled to the main body, it is necessary to prevent foreign matter from entering the main body. For this purpose, in addition to the filter modules 1000, 2000, and 3000 described above, an additional secondary filter module may be required.

[0197] For the sake of ease of description, the following mainly describes the case where the filter module 1000 according to the first exemplary embodiment is used in a cooling device, but the technical concept of the present disclosure is not limited to this, and the content of the secondary filter module described below can be applied not only to the case where the filter modules 2000 and 3000 according to the second exemplary embodiment or the third exemplary embodiment are used, but also to the case where other types of filter modules are used or where no filter module is used.

[0198] Fig.19 1 is a view showing a secondary filter module according to an exemplary embodiment of the present disclosure. Hereinafter, for convenience of description, the existing filter module 1000 will be referred to as a first filter module, and the filter 1400 will be referred to as a first filter.

[0199] refer to Fig.19 , the second filter module may include a second filter 1500 and a second filter receiving member 1600 .

[0200] The second filter 1500 may be made of various materials. For example, the second filter 1500 may be made of various materials such as paper, metal, synthetic fiber, or polymer compound.

[0201] When the cooling device is used, the second filter 1500 can be reused many times, and in this case, the material of the second filter 1500 may include a metal material such as stainless steel or nickel. When the material of the second filter 1500 is metal, durability is ensured compared to the case where the material is paper, so it can be reused. However, the second filter 1500 may be a disposable filter that must be replaced whenever the cooling device is used. In this case, the second filter 1500 may be implemented as a paper filter to reduce manufacturing costs.

[0202] The second filter 1500 and the first filter 1400 may be made of different materials. For example, the first filter 1400 may be a consumable filter made of paper, while the second filter 1500 may be a recyclable filter made of metal.

[0203] The second filter 1500 may be implemented in the form of a mesh net. For example, the second filter 1500 may be in the form of a net including a plurality of holes having a predetermined size.

[0204] The second filter 1500 may be implemented in various shapes. For example, the second filter 1500 may be implemented in a disk shape having a predetermined diameter and a circular cross-section or a disk shape having a predetermined width and a square cross-section.

[0205] The second filter 1500 may have a similar shape to the first filter 1400. However, the size of the first filter 1400 may be greater than or equal to the size of the second filter 1500. Alternatively, the second filter 1500 may have a different shape from the first filter 1400. For example, the second filter 1500 may be a disc-shaped having a circular cross-section, while the first filter 1000 may be a disc-shaped having a polygonal cross-section including at least one protrusion.

[0206] The second filter receiving member 1600 may receive the second filter 1500. The second filter receiving member 1600 may include an inner space for receiving the second filter 1500.

[0207] The second filter receiving member 1600 may be coupled to the body. Fig.19 , the second filter receiving member 1600 may be fixed to the body by the fixing members FE1 and FE2. In the process of coupling the second filter receiving member 1600 with the body, a gasket may be received in the inner space of the second filter receiving member 1600.

[0208] The gasket is embedded in the body of the cooling device and is connected to the valve fluid to guide the flow of the coolant. Specifically, the gasket is connected to the valve or to a conduit connected to the valve, and when the coolant storage unit is connected to the body, the gasket is connected to the coolant storage unit fluid so that the coolant in the coolant storage unit can move to the valve through the gasket.

[0209] The gasket may have various shapes. For example, the gasket may be implemented in the form of a disk having a circular cross section. For another example, the gasket may be implemented in the form of a disk having a cross section corresponding to the shape of the second filter 1500.

[0210] The gasket may support the second filter 1500. For example, the second filter 1500 may be disposed in a state of surface contact with the gasket. At this time, the shape of the gasket may correspond to the shape of the second filter 1500. In this case, the gasket may be understood as a second filter supporting unit.

[0211] The gasket may include a hole through which the coolant moves. Since the second filter 1500 is located at one side of the gasket, one end of the hole of the gasket may be partially blocked by the second filter 1500. In other words, the second filter 1500 may prevent foreign matter from flowing into one end of the hole of the gasket.

[0212] Since the second filter receiving member 1600 is coupled to the body and the gasket is received in the inner space of the second filter receiving member 1600 , the second filter 1500 may be disposed between the gasket and the second filter receiving member 1600 .

[0213] As described above, when the second filter module is connected to the body, the second filter 1500 can be arranged between the part where the coolant moves in the cooling device (such as the conduit through which the coolant flows) and the outside, thereby preventing foreign matter from entering the cooling device when the cooling device is not in use.

[0214] In addition, in the process of coolant flowing from the coolant storage unit (e.g., a cartridge) into the cooling device, the coolant can move to the gasket through at least the second filter receiving member 1600 and the second filter 1500, and impurities can be filtered in the process. In addition, the first filter module 1000 is provided between the second filter module and the coolant storage unit, so that impurities contained in the coolant can be filtered multiple times in the process of the coolant flowing into the cooling device.

[0215] The above-mentioned features, structures, effects, etc. in the exemplary embodiments are included in at least one exemplary embodiment of the present disclosure, and are not necessarily limited to one exemplary embodiment. In addition, for those of ordinary skill in the art, the features, structures, effects, etc. illustrated in each exemplary embodiment can be combined or modified in other exemplary embodiments. Therefore, the contents related to these combinations and modifications should be interpreted as being included in the scope of the present disclosure.

[0216] In addition, although the exemplary embodiments have been described above, they are only examples and do not limit the present disclosure, and those skilled in the art to which the present disclosure belongs will recognize that various modifications and applications not shown above are possible without departing from the essential characteristics of the exemplary embodiments. That is, each component specifically shown in the exemplary embodiments can be implemented by modifying it. Differences in these changes and applications should be interpreted as falling within the scope of the present disclosure defined by the appended claims.
