Description

Technical Field

[0001] The invention relates to the technical field of marine engineering, and in particular to a wall-attached heat-conducting structure and a layered underwater electronic cabin. Background Art

[0002] In the field of marine engineering technology, electronic equipment needs to be assembled in a sealed cabin when working underwater. The completely closed environment makes it difficult for electronic equipment to dissipate heat. Conventional fan cooling methods cannot be used, and heat can only be dissipated through heat conduction and heat radiation. Heat conduction has become its main heat dissipation method due to its large heat dissipation capacity. In order to improve the heat dissipation efficiency, in conventional underwater electronic cabins, electronic equipment is installed close to the inner wall of the cabin. This structure is conducive to the smooth export of heat to the cabin, but the space utilization rate of the structure in the center of the cabin is not high, which is not conducive to the compact structural design of complex systems.

[0007] The rear heat-conducting tensioning strip is slidably connected in the mounting groove on the rear side of the heat-conducting mounting base plate;

[0008] The front heat conduction tensioning strip is slidably connected in the installation groove on the front side of the heat conduction installation base plate;

[0009] Two sets of tensioning screws pass through the interlayer connecting plates in the cabin and are respectively threadedly connected to the screw holes opened on the rear front side of the heat-conducting installation base plate. The inner end faces of the two sets of tensioning screws are respectively abutted against the side faces of the rear heat-conducting tensioning strip and the front heat-conducting tensioning strip. By rotating the tensioning screws forward and backward, the rear heat-conducting tensioning strip and the front heat-conducting tensioning strip are respectively tightened or disengaged from the inner wall of the cabin, thereby realizing the adjustment of the heat-conducting area of ​​the rear heat-conducting tensioning strip and the front heat-conducting tensioning strip and the inner wall of the cabin.

[0010] Furthermore, the rear heat-conducting expansion strip and / or the front heat-conducting expansion strip abut against upper and lower inner walls of the mounting groove on the heat-conducting mounting base plate.

[0011] Furthermore, the rear heat-conducting expansion strip and / or the front heat-conducting expansion strip are made of copper.

[0012] Furthermore, the rear heat-conducting expansion strip and the front heat-conducting expansion strip are arranged in an arc shape on the side facing the inner wall of the cabin. When the rear heat-conducting expansion strip and the front heat-conducting expansion strip abut against the inner wall of the cabin, the side surfaces of the rear heat-conducting expansion strip and the front heat-conducting expansion strip are completely fitted with the inner wall of the cabin.

[0013] Furthermore, the rear heat-conducting expansion strip and / or the front heat-conducting expansion strip are in the shape of an oblique wedge.

[0014] Another aspect of the present invention further provides a layered underwater electronic cabin, comprising a plurality of wall-attached heat-conducting structures, a cabin body, and electronic equipment;

[0015] The cabin body includes a left sealed end cover, a shell, an interlayer connecting plate and a right sealed end cover; the left sealed end cover and the right sealed end cover are respectively sealed and fixedly installed on the left and right end surfaces of the shell, and a plurality of wall-attached heat-conducting structures are laterally spaced and fixedly installed in the installation space surrounded by the left sealed end cover and the interlayer connecting plate in the shell, and the electronic equipment is divided into multiple groups and respectively arranged on the heat-conducting installation base plates of the plurality of wall-attached heat-conducting structures.

[0016] Furthermore, a plurality of wiring holes are provided on the heat-conducting mounting base plate to realize electrical connection of electronic devices between the plurality of heat-conducting mounting base plates.

[0017] Furthermore, the number of the wall-attached heat-conducting structures is 2 to 6.

[0018] Beneficial effects of the present invention:

[0019] 1. The front heat-conducting expansion strip and the rear heat-conducting expansion strip in the wall-attached heat-conducting structure of the present invention are both slidably connected in the installation grooves on the front and rear sides of the heat-conducting installation base plate, and two tightening screws are respectively abutted on the end faces of the front heat-conducting expansion strip and the rear heat-conducting expansion strip. By rotating the two tightening screws forward and backward, the front heat-conducting expansion strip and the rear heat-conducting expansion strip can be tightened on the inner wall of the cabin respectively, thereby increasing the heat conduction area between the rear heat-conducting expansion strip and the front heat-conducting expansion strip and the inner wall of the cabin, thereby improving the heat dissipation effect.

[0038] Reference Figure 1 , the embodiment of the present application provides a wall-attached heat-conducting structure, comprising:

[0039] A heat-conducting mounting base plate 4 on which a plurality of electronic devices 2 are distributed, and mounting grooves 41 are obliquely provided on both the rear and front sides of the heat-conducting mounting base plate 4;

[0040] The rear heat-conducting expansion strip 3 is slidably connected in the mounting groove 41 on the rear side of the heat-conducting mounting base plate 4;

[0041] The front heat-conducting tensioning strip 6 is slidably connected in the mounting groove 41 on the front side of the heat-conducting mounting base plate 4;

[0042] Two sets of tensioning screws 5 pass through the interlayer connecting plate 7 in the cabin and are respectively threadedly connected to the screw holes opened on the rear front side of the heat-conducting mounting base plate 4, and the inner end faces of the two sets of tensioning screws 5 are respectively abutted against the side faces of the rear heat-conducting tensioning strip 3 and the front heat-conducting tensioning strip 6; by rotating the tensioning screws 5 forward and reverse, the rear heat-conducting tensioning strip 3 and the front heat-conducting tensioning strip 6 are respectively tightened or disengaged from the inner wall of the cabin, thereby realizing the adjustment of the heat-conducting area of ​​the rear heat-conducting tensioning strip 3 and the front heat-conducting tensioning strip 6 and the inner wall of the cabin.

[0043] Preferably, the number of tension screws 5 in each group is one, and the total number of tension screws 5 in a single wall-attached heat-conducting structure is two, that is, a screw hole is opened on each of the front and rear sides of the heat-conducting mounting base plate 4, and two tension screws 5 are respectively threadedly connected in the two screw holes.

[0044] Reference Figure 2 and Figure 3 When in use, the two tensioning screws 5 are rotated forward. During the screwing-in process of the two tensioning screws 5, due to the action of the oblique wedge-shaped surfaces between the rear heat-conducting tensioning strip 3 and the front heat-conducting tensioning strip 6 and the heat-conducting mounting base plate 4, the rear heat-conducting tensioning strip 3 and the front heat-conducting tensioning strip 6 are pushed inward, and at the same time, the rear heat-conducting tensioning strip 3 and the front heat-conducting tensioning strip 6 are pushed toward the outer circumferential direction of the inner wall of the cabin, thereby pressing them against the inner wall of the cabin, increasing the heat conduction area between the rear heat-conducting tensioning strip 3, the front heat-conducting tensioning strip 6 and the inner wall of the cabin, and improving the heat dissipation effect.

[0045] In addition, the two tensioning screws 5 in the present invention have two different functions. Function one: the heat-conducting mounting base plate 4 is fixedly installed on the inner wall of the cabin by the two tensioning screws 5, so as to achieve the fixation of the heat-conducting mounting base plate 4; Function two: by adjusting the heat-conducting area of ​​the front heat-conducting tensioning strip 6 and the rear heat-conducting tensioning strip 3 respectively with the inner wall of the cabin, the heat dissipation effect is adjusted.

[0046] In some embodiments, the rear thermal expansion strip 3 and / or the front thermal expansion strip 6 abut against the upper and lower inner walls of the mounting groove 41 on the thermal mounting base plate 4. This design can increase the contact area between the rear thermal expansion strip 3 and / or the front thermal expansion strip 6 and the thermal mounting base plate 4, further improving the heat dissipation effect of the wall-mounted thermal conductive structure.

[0047] In some embodiments, the rear thermally conductive expansion strip 3 and / or the front thermally conductive expansion strip 6 are made of red copper, which has good thermal conductivity and improves the heat conduction efficiency of the wall-attached thermal conductive structure; in addition, the rear thermally conductive expansion strip 3 and / or the front thermally conductive expansion strip 6 are not limited to red copper, and other materials with good thermal conductivity can also be used, such as thermally conductive ceramics or other metals with good thermal conductivity.

[0048] In some embodiments, the rear thermal expansion strip 3 and the front thermal expansion strip 6 are arranged in an arc shape on the side facing the inner wall of the cabin. When the rear thermal expansion strip 3 and the front thermal expansion strip 6 are in contact with the inner wall of the cabin, the side surfaces of the rear thermal expansion strip 3 and the front thermal expansion strip 6 are completely in contact with the inner wall of the cabin. This design can further increase the heat conduction area between the rear thermal expansion strip 3 and the front thermal expansion strip 6 and the inner wall of the cabin, and further improve the heat dissipation effect of the wall-attached thermal conductive structure.

[0049] In some embodiments, the shape of the rear thermal expansion strip 3 and / or the front thermal expansion strip 6 is an inclined wedge. In addition, the shape of the rear thermal expansion strip 3 and / or the front thermal expansion strip 6 is not limited to an inclined wedge, but may also be other shapes that can facilitate the movement of the rear thermal expansion strip 3 and the front thermal expansion strip 6 in the installation groove 41 and increase the heat conduction area between the rear thermal expansion strip 3 and the front thermal expansion strip 6 and the inner wall of the cabin.

At this moment, the tensioning screws 5 and the heat-conducting mounting base plate 4 are in a rotating state. Loose state, and then push the assembled overall structure into the inner side of the shell 8. After it is assembled in place, tighten the front and rear tensioning screws 5 of each layer of the wall-attached heat-conducting structure at the opening at the right end of the shell 8, so that the rear heat-conducting tensioning strip 3 and the front heat-conducting tensioning strip 6 are pushed inward, and at the same time, the rear heat-conducting tensioning strip 3 and the front heat-conducting tensioning strip 6 are pushed toward the outer circumferential direction of the inner wall of the cabin, thereby pressing them against the inner wall of the shell 8 (that is, the inner wall of the cabin mentioned above), increasing the heat-conducting area between the rear heat-conducting tensioning strip 3 and the front heat-conducting tensioning strip 6 and the inner wall of the shell 8. After all the tensioning screws 5 are tightened, the right sealing end cover 9 is installed into the shell 8 to complete the installation of the layered underwater electronic cabin.

[0054] In some embodiments, the thermally conductive mounting base plate 4 is provided with a plurality of wiring holes to realize electrical connection of electronic devices 2 between multiple thermally conductive mounting base plates 4.
