[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a heat dissipation box structure and a box-type FTU equipment. Background Art

[0002] The distribution switch monitoring terminal (FTU for short) has the functions of remote control, telemetry, telesignaling, and fault detection, and communicates with the distribution automation master station to provide the operation status of the distribution system and various parameters and information required for monitoring and control. At the same time, it executes the commands issued by the distribution master station to adjust and control the distribution equipment, and realizes the functions of fault location, fault isolation, and rapid restoration of power supply in non-fault areas. The box-type FTU is to install the FTU in a protective box to prevent damage from the external environment to adapt to various complex environments, and is easy to install and maintain. In some special use environments, the box-type FTU needs to have windproof, rainproof, dustproof and other properties. For example, in a humid environment, it is necessary to effectively prevent moisture from invading the inside of the box to ensure the normal operation of the equipment; in an outdoor environment, the box-type FTU needs to have good rainproof, dustproof and other properties to protect the equipment from the influence of the natural environment. For this reason, the box of this type of box-type FTU needs to be designed as a closed box. For an FTU equipped with many electronic control devices, a lot of heat is generated inside. It is difficult for a closed box-type FTU to discharge the internal heat. Long-term use will cause the performance of the electronic control devices to deteriorate or even damage the electronic control devices. Therefore, a heat dissipation box structure and a box-type FTU device are proposed. Utility Model Content

[0003] The utility model aims to provide a heat dissipation box structure and a box-type FTU device to solve the technical problem that the heat inside the closed box-type FTU is difficult to discharge, and long-term use will cause the performance of the internal electronic control components to decline or even damage the electronic control components.

[0026] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0027] Embodiment 1:

[0028] An embodiment of the utility model provides a heat dissipation box structure, which can be applied to structures such as FTU, uninterruptible power supply, frequency converter, rectifier, inverter, etc., to provide a closed box structure for them to protect their internal equipment. That is, in this embodiment, the heat dissipation box structure can be a box-type FTU structure.

[0029] Reference Figures 1 to 3 The embodiment of the utility model provides a box-type FTU structure, including a box body 10, a heat absorption system 20, a hydraulic pump 30 and a heat dissipation mechanism 40. The box body 10 is in a rectangular shape and has an opening on one side. A support plate 12 is provided on the bottom surface of the box body 10 to support the box body 10, and the support plate 12 is integrally formed with the box body 10. A box door 11 is provided on one side of the opening of the box body 10, and the box door 11 is rotatably connected to the box body 10 to seal the inner cavity of the box body 10.

[0030] The heat absorption system 20 is arranged in the box body 10, and the heat absorption system 20 includes a heat pipe 21 arranged on the inner wall of the box body 10 and a liquid channel arranged in the box body 10, and the heat pipe 21 is connected to the liquid channel to form a heat absorption channel surrounding the box body 10. Optionally, the heat pipe 21 is half-embedded in the inner wall of the box body 10, that is, a part of the heat pipe 21 is exposed in the inner cavity of the box body 10, which increases the contact area between the outer wall surface of the heat pipe 21 and the inner cavity of the box body 10 without affecting the installation of the FTU. Preferably, the material of the heat pipe 21 is a material with a high heat dissipation coefficient, such as the heat pipe 21 is one of a copper tube, an aluminum tube or a stainless steel tube. The upper end surface of the box body 10 is provided with a channel inlet and a channel outlet to inject and discharge coolant into the heat absorption channel. The hydraulic pump 30 is mounted on the box body 10 through a mounting seat 31, and the hydraulic pump 30 is connected to the heat absorption system 20 to drive the coolant in the heat absorption channel to flow. Specifically, the outlet of the hydraulic pump 30 is connected to the channel inlet through a pipeline, and the inlet of the hydraulic pump 30 is connected to the channel outlet through a pipeline.

[0031] The heat dissipation mechanism 40 is disposed on the upper end surface of the housing 10, and the heat dissipation mechanism 40 includes a liquid storage tank 41 and a plurality of heat dissipation fins 42. The liquid storage tank 41 is mounted on the housing 10 through a support column 44, and the heat dissipation fins 42 penetrate a side wall of the liquid storage tank 41, so that a portion of the heat dissipation fins 42 is embedded in the inner cavity of the liquid storage tank 41, and another portion is exposed outside the liquid storage tank 41. Specifically, the heat dissipation fins 42 penetrate a set of opposite side walls of the liquid storage tank 41, and the side walls of the liquid storage tank 41 divide the heat dissipation fins 42 into a heat absorption part and a heat dissipation part, that is, the part located inside the liquid storage tank 41 is the heat absorption part, which is used to absorb the heat in the coolant; the part located outside the liquid storage tank 41 is the heat dissipation part, which is used to dissipate the heat of the heat absorption part. It should be noted that the heat sink 42 only penetrates the side wall of one side of the liquid storage tank 41, and two adjacent heat sinks 42 penetrate different side walls of the liquid storage tank 41 respectively, increasing the distance between the two adjacent heat sinks 42 outside the same side of the liquid storage tank 41, thereby improving the heat dissipation effect. An inlet and an outlet for the input and output of the coolant are provided on another set of opposite side walls of the liquid storage tank 41, and are located on different side walls. The liquid storage tank 41 is connected to the heat absorption system 20 through a pipeline. Specifically, the inlet of the liquid storage tank 41 is connected to the channel outlet through a pipeline, and the outlet of the liquid storage tank 41 is connected to the inlet of the hydraulic pump 30 through a pipeline.

[0032] Reference Figure 2The heat absorption system 20 further includes a heat absorption sheet 22, which is embedded in the heat conducting pipe 21, and a portion of the heat absorption sheet 22 is exposed on the inner cavity of the box 10, and the other portion penetrates the tube wall of the heat conducting pipe 21 and is embedded in the pipe of the heat conducting pipe 21. The length direction of the heat absorption sheet 22 is the same as the flow direction of the coolant, that is, the portion of the heat absorption sheet 22 embedded in the heat conducting pipe 21 will not hinder the flow of the coolant. The portion of the heat absorption sheet 22 exposed on the inner cavity of the box 10 increases the speed of heat transfer from the box 10 to the coolant, thereby increasing the heat absorption effect of the heat absorption system 20.

[0033] Reference Figure 3 , the heat sink 42 isolates the inner cavity of the liquid storage tank 41 into a plurality of independent liquid storage spaces of equal volume. A through hole 43 is provided on the heat absorption part of the heat sink 42, and two adjacent liquid storage spaces are connected through the through hole 43. Specifically, the through holes 43 on the two adjacent heat sinks 42 are respectively provided at opposite ends of the heat absorption part. In the process of the coolant flowing from the inlet of the liquid storage tank 41 to the outlet of the liquid storage tank 41, the coolant needs to flow from one end of the liquid storage space to the other end before it can flow to the next liquid storage space through the through hole 43, which increases the travel of the coolant in the liquid storage tank 41, thereby increasing the contact area between the coolant and the heat sink 42, and further improving the heat dissipation effect of the heat dissipation mechanism 40.

[0034] It should be noted that the coolant is one of water, ethylene glycol-based coolant, propylene glycol-based coolant, a water-ethylene glycol mixture, or other liquids with a cooling effect.

[0035] The utility model discloses a heat dissipation box structure, and the specific implementation method is as follows: when dissipating heat, coolant is injected into the liquid storage tank 41, and the coolant is driven by the hydraulic pump 30 to circulate around the box 10. When the coolant flows through the heat absorption system 20, the heat in the box 10 is absorbed; when the coolant flows to the heat dissipation system, the heat in the coolant is dissipated. Specifically, the hydraulic pump 30 injects the coolant of the liquid storage tank 41 into the heat absorption system 20 through the channel inlet, and the heat absorption system 20 surrounds the inner wall of the box 10. The heat in the inner cavity of the box 10 is transferred to the coolant through the heat conduction pipe 21. The coolant after absorbing heat flows into the liquid storage tank 41 through the channel outlet. In the liquid storage tank 41, the coolant passes through a plurality of heat sinks 42, and the heat sinks 42 dissipate the heat in the coolant, thereby reducing the temperature of the coolant. The cooled coolant flows into the heat absorption system 20 through the hydraulic pump 30 to form a cycle. The heat dissipation box structure disclosed by the utility model absorbs the heat in the box 10 through the circulating coolant, and dissipates the heat of the coolant outside the box 10, forming a heat absorption-heat dissipation thermal cycle, effectively dissipating the heat in the closed box-type FTU, and reducing the risk of performance degradation or even damage to the electronic control components due to the high temperature in the box when the box-type FTU is used for a long time.

[0036] The utility model also discloses a box-type FTU device, including the above-mentioned heat dissipation box structure, wherein a distribution switch monitoring terminal is installed in the box 10 of the heat dissipation box structure. The box forms a closed inner cavity after the box door 11 is closed, which has the effect of waterproofing and dustproofing the FTU; at the same time, it can effectively discharge the heat generated by the FTU when it is working out of the box 10, avoiding the performance degradation or damage of the FTU due to high temperature.

[0037] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
