The heat exchanger is configured to exchange heat with a coolant flowing through the head. The shaft also includes first and second cooling channels. The first cooling channel is configured to deliver the coolant to the heat exchanger, and the second cooling channel is configured to exhaust the coolant from the heat exchanger. The apparatus may also include a first seal between the head and the structure that is configured to reduce or prevent coolant loss. The apparatus may further include a second seal that is configured to reduce or prevent coolant flow between the first and second cooling channels that bypasses the heat exchanger. ## Claims ### Claim 1 A threaded cooling apparatus comprising: a head comprising a heat exchanger; and a shaft comprising a threaded section configured to mechanically fasten the head to a structure; wherein the heat exchanger is configured to exchange heat with a coolant flowing through the head; and wherein the shaft further comprises first and second cooling channels, the first cooling channel configured to deliver the coolant to the heat exchanger, the second cooling channel configured to exhaust the coolant from the heat exchanger. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the heat exchanger is configured to translate perpendicular to a surface of the structure based on rotation of the apparatus. ### Claim 3 (depends on 1) The apparatus of claim 1, further comprising: a first seal between the head and the structure, the first seal configured to reduce or prevent coolant loss. ### Claim 4 (depends on 3) The apparatus of claim 3, further comprising: a second seal configured to reduce or prevent coolant flow between the first and second cooling channels that bypasses the heat exchanger. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the head and the shaft form a bolt. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the first cooling channel extends along an entire length of the shaft. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the first cooling channel extends along part but not all of a length of the shaft and is angled so that an entry to the first cooling channel is located along a side of the shaft. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the second cooling channel comprises a groove through at least part of the shaft. ### Claim 9 A system comprising: a threaded cooling apparatus comprising: a head comprising a heat exchanger; and a shaft comprising a threaded section; wherein the heat exchanger is configured to exchange heat with a coolant flowing through the head; and wherein the shaft further comprises first and second cooling channels, the first cooling channel configured to deliver the coolant to the heat exchanger, the second cooling channel configured to exhaust the coolant from the heat exchanger; a manifold comprising first and second coolant channels, the first coolant channel configured to provide the coolant to the first cooling channel of the threaded cooling apparatus, the second coolant channel configured to return the coolant from the second cooling channel of the threaded cooling apparatus; wherein the threaded section is configured to mechanically fasten the head to the manifold. ### Claim 10 (depends on 9) The system of claim 9, wherein the heat exchanger is configured to translate perpendicular to a surface of the manifold based on rotation of the threaded cooling apparatus. ### Claim 11 (depends on 9) The system of claim 9, wherein the threaded cooling apparatus further comprises a first seal between the head and the manifold, the first seal configured to reduce or prevent coolant loss. ### Claim 12 (depends on 11) The system of claim 11, wherein the threaded cooling apparatus further comprises a second seal configured to reduce or prevent coolant flow between the first and second cooling channels that bypasses the heat exchanger. ### Claim 13 (depends on 9) The system of claim 9, wherein the threaded cooling apparatus comprises a bolt. ### Claim 14 (depends on 9) The system of claim 9, wherein the first cooling channel extends along an entire length of the shaft. ### Claim 15 (depends on 9) The system of claim 9, wherein the first cooling channel extends along part but not all of a length of the shaft and is angled so that an entry to the first cooling channel is located along a side of the shaft ### Claim 16 (depends on 9) The system of claim 9, wherein the second cooling channel comprises a groove through at least part of the shaft. ### Claim 17 A method comprising: inserting a threaded cooling apparatus into a structure, the threaded cooling apparatus comprising a head and a shaft, the head comprising a heat exchanger, the shaft comprising a threaded section configured to mechanically fasten the head to the structure; providing coolant to the heat exchanger through a first cooling channel in the shaft, the heat exchanger configured to exchange heat with the coolant flowing through the head; and exhausting the coolant from the heat exchanger through a second cooling channel in the shaft. ### Claim 18 (depends on 17) The method of claim 17, wherein during insertion the heat exchanger translates perpendicular to a surface of the structure based on rotation of the threaded cooling apparatus. ### Claim 19 (depends on 17) The method of claim 17, wherein the threaded cooling apparatus further comprises a first seal between the head and the manifold, the first seal configured to reduce or prevent coolant loss. ### Claim 20 (depends on 19) The method of claim 19, wherein the threaded cooling apparatus further comprises a second seal configured to reduce or prevent coolant flow between the first and second cooling channels that bypasses the heat exchanger.
