[0026] The technical scheme of the present embodiment is further illustrated below by combining the drawings and through the specific embodiments.

[0027] As Figures 1-3As shown, the embodiment provides a heat dissipation device for a charging time instrument, which comprises a backboard 10 of a case, a fan system 20, a heat conducting component and a radiator 50. The case of the charging time instrument and the fan system 20 are both installed on the inner side of the backboard 10 of the case, and the fan system 20 is located above the heating device in the charging time instrument. The radiator 50 is arranged on the outer side of the backboard 10 of the case. The inner and outer sides of the backboard 10 of the case are both provided with the heat conducting component, and the heat conducting component is connected to the heating device and the radiator 50 respectively, so that the heat generated by the heating device during the operation of the charging time instrument is transmitted to the backboard 10 of the case through the heat conducting component, and then transmitted to the radiator 50 through the heat conducting component for heat dissipation.

[0028] Specifically, in the embodiment, the fan system 20 and the radiator 50 are arranged on the inner and outer sides of the backboard 10 of the case respectively, and the heat conducting component is additionally arranged, so that the heat generated by the charging time instrument installed on the inner side of the backboard 10 of the case during the operation of the charging time instrument is transmitted to the radiator 50 in time under the cooperation of the heat conducting component and the fan system 20, and then the heat is dissipated from the inside of the equipment to the outside, so that the heat dissipation effect is achieved. Meanwhile, the heat dissipation mode of the embodiment can not only ensure the sealing condition of the charging time instrument when used at sea, but also avoid the influence of the harsh working environment in the wild, and can quickly dissipate the heat generated by the charging time instrument to the external environment, so as to ensure the working temperature of the charging time instrument, and then improve the stability of the marine node during the charging process, and prolong the service life.

[0029] The specific structure of the heat dissipation device for the charging time instrument in the embodiment will be described below.

[0030] As shown in the drawings, Figures 1-3As shown, the heat dissipation device of the charging time instrument in the embodiment comprises a backboard 10 of a case, a fan system 20, a heat conducting component, a radiator 50 and a welding tool 60. Specifically, the case of the charging time instrument in the embodiment can be mounted on the backboard 10 of the case and surrounded by the backboard 10 to form a sealed space. Further, the fan system 20 and the case of the charging time instrument are both mounted on the inner side of the backboard 10 of the case, and the fan system 20 is located above the heating device in the charging time instrument, so as to improve the heat dissipation efficiency of the heating device after generating heat during operation. Alternatively, the heat conducting component is arranged on the inner and outer sides of the backboard 10 of the case, and the radiator 50 is arranged on the outer side of the backboard 10 of the case, and the heat conducting component can be connected to the heating device in the charging time instrument on the inner side and the radiator 50 on the outer side, respectively. In this way, when the charging time instrument is operating and the heating device generates heat, the heat of the heating device in the charging time instrument can be transmitted to the backboard 10 of the case through the heat conducting component placed on the inner side, and then transmitted to the heat conducting component on the outer side through the backboard 10 of the case, and finally transmitted to the radiator 50 through the heat conducting component, so as to achieve the heat dissipation effect. Specifically, the heat dissipation efficiency can be further improved under the action of the fan system 20, so as to conduct the heat in the sealed space to the external environment, thereby avoiding the generation of a large amount of heat while ensuring the normal operation of the charging time instrument. Specifically, the welding tool 60 is further arranged in the embodiment, so as to ensure accurate installation of the heating device in the charging time instrument during installation.

[0031] In combination Figure 1 As shown, the fan system 20 in the embodiment comprises a support plate 21, a support rod 22 and a fan 23. Specifically, the support plate 21 is fixed to the backboard 10 of the case through the support rod 22, and a plurality of fans 23 are arranged on the support plate 21 at intervals and can blow air towards the heating device in the charging time instrument, so as to improve the heat dissipation efficiency. Exemplarily, four support rods 22 are arranged in the embodiment, and the four support rods 22 are arranged at the four top corners of the support plate 21, respectively, so as to ensure the stable support of the support plate 21, thereby ensuring the stability of the subsequent operation of the fan 23. Exemplarily, the power of each fan 23 in the embodiment is not less than 8w, and the fan 23 rotates synchronously with the charging time instrument when the charging time instrument starts to operate, so as to ensure the heat dissipation effect of the heating device.

[0032] Optionally, since the charging time instrument is installed on the back plate 10 of the case, a sealed space is formed, and the fan system 20 is arranged directly above the heating device in the charging time instrument, which not only effectively improves the space utilization inside, but also blows the heating device. For example, the input voltage of the fan system 20 in the embodiment is provided by the charging circuit board in the charging time instrument, and the heating device is arranged on the charging circuit board. When the charging time instrument works, the charging circuit board starts to work, at which time the fan system 20 can start to work at the same time. Since the charging circuit board belongs to large current charging, a large amount of heat will be generated on the heating device, which can be effectively cooled by the fan system 20, and the heat can be blown to the heat conduction assembly below the heating device in time. Specifically, the through hole 101 is arranged on the back plate 10 of the case, and the support rod 22 can pass through the through hole 101 and be connected to the radiator 50, so that the fan system 20 and the radiator 50 are stably installed on the back plate 10 of the case, ensuring the stability of the subsequent heat dissipation process. For example, the through hole 101 and the support rod 22 are arranged one by one, and there are also four of them.

[0033] Correspondingly, at least 14 mounting holes 102 are arranged on the back plate 10 of the case for mounting the charging time instrument, so as to ensure the close connection between the two. Further, 56 threaded holes for mounting the heating device are arranged on the inner side of the back plate 10, and 6 threaded holes for mounting the temperature sensor lead are arranged correspondingly, so as to realize real-time measurement and control of the temperature of the heating device and the internal sealed space. For example, the threaded holes for mounting the heating device are arranged one by one with the positioning through holes on the heat conduction assembly, so as to ensure that the heat conduction assembly and the heating device in the charging time instrument are installed one by one. Further, considering the sealing of the whole device, the thermal conductivity of the material itself, and the strength requirement of the installation of other parts, the back plate 10 of the case is preferably made of aluminum alloy material, and the thickness is not less than 10 mm.

[0034] In combination with Figure 1 and Figure 2 It is shown that the heat conduction assembly in the embodiment includes a first heat conduction member 30 and a second heat conduction member 40. Specifically, the first heat conduction member 30 is arranged on the inner side of the back plate 10 and below the heating device in the charging time instrument, and the first heat conduction member 30 is arranged one by one with the heating device, so as to ensure that each heating device can be effectively heat-conducted, thereby improving the heat dissipation efficiency of the whole device. Further, the second heat conduction member 40 is arranged on the outer side of the back plate 10 and clamped between the back plate 10 and the radiator 50, so as to timely transfer the heat on the inner side of the back plate 10 to the radiator 50 connected on the outer side, and quickly release the heat in the sealed space to the external environment through the radiator 50.

[0035] Exemplarily, the first heat conducting member 30 and the second heat conducting member 40 in the heat conducting assembly in the embodiment are both made of silica gel material, the shape of the first heat conducting member 30 is set as a rectangle, and the first heat conducting member 30 is provided with a positioning through hole, so as to ensure that when the first heat conducting member 30 is attached to the inner side surface of the cabinet back plate 10, the installation direction position of the first heat conducting member 30 is consistent with the heat generating devices on the charging circuit board, so as to be able to conduct the heat of each heat generating device to the cabinet back plate 10. Further, the shape of the second heat conducting member 40 is an irregular shape cut from a rectangle, and the shape of the second heat conducting member 40 is consistent with the mounting surface shape of the heat sink 50, so as to be able to uniformly conduct the heat of the cabinet back plate 10 to the heat sink 50.

[0036] As shown in Figure 2 , the heat sink 50 in the embodiment is made of aluminum alloy material, and is provided as a toothed structure with multiple layers, so that when the charging time instrument works, the heat generated by the heat generating devices on the charging circuit board can be conducted to the cabinet back plate 10 through the first heat conducting member 30, and then conducted to the heat sink 50 through the second heat conducting member 40, and then dissipated to the external environment through the large area of the heat sink 50, thereby realizing the heat dissipation effect of the internal sealed environment, ensuring the normal work of the charging time instrument, and quickly conducting the heat to the external environment. Exemplarily, the shape of the heat sink 50 in the embodiment is preferably an irregular shape cut from a rectangle, and is maximally attached to the outer side surface of the cabinet back plate 10, so as to ensure the area of the heat sink 50 and improve the heat dissipation effect.

[0037] As shown in Figure 1 and Figure 3 , in the embodiment, since the connection mode of the heat generating devices on the charging circuit board and the charging circuit board is pin welding, the number of heat generating devices is relatively large, and considering the one-to-one correspondence between the heat generating devices and the first heat conducting member 30, and in order to ensure the close contact between the heat generating devices and the first heat conducting member 30, the welding installation between the heat generating devices and the charging circuit board needs to be carried out through the welding tool 60, so as to ensure the accuracy of welding, and thereby the spacing of the heat generating devices on the charging circuit board meets the requirements. Further, under the auxiliary welding action of the welding tool 60, the heat generating devices can be installed one by one corresponding to the first heat conducting member 30 in the heat conducting assembly when the charging time instrument is installed. Exemplarily, the welding tool 60 is provided with a positioning hole, and the interval between every two adjacent positioning holes is the same as the interval between every two adjacent positioning through holes on the first heat conducting member 30, so as to ensure the accurate installation between the heat generating devices and the first heat conducting member 30.

[0038] To sum up, in the process of charging and time service instrument charging work, the heat generating device on the charging circuit board inside will produce a large amount of heat, and through the charging and time service instrument heat dissipation device in the embodiment, the heat conduction mode of the charging circuit board - the backboard 10 of the case - the radiator 50 can be opened from inside to outside, so that the heat generated inside the charging and time service instrument during work is conducted to the external environment. Further, under the action of the internal fan system 20, the heat transfer process can be further promoted, so that the heat dissipation capacity of the charging and time service instrument during work is greatly improved, thereby ensuring that the charging and time service instrument is always in a suitable temperature during work.
