Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering equipment, in particular to a heat dissipation device for an electrical cabinet in construction engineering. Background Technique

[0002] Construction engineering refers to a work of constructing various housing buildings and their affiliated facilities and installing the supporting lines, pipelines, and equipment. Various electrical cabinets will be used in it. The electrical cabinet is a cabinet made of steel materials to protect the normal operation of components. The production materials of the electrical cabinet are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. The cold-rolled steel plate is relatively softer in material and more suitable for the production of electrical cabinets. The electrical cabinet has a wide range of uses and is mainly used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc.

[0003] According to the publication number: CN219351059, an electrical cabinet for construction engineering is disclosed, including a cabinet body and a protection plate. A wire bundling plate is welded inside the cabinet body, and the wire bundling plate is integrally structured with the cabinet body. A vertical rod is provided on the cabinet body, and a baffle is welded at the top of the vertical rod. A connecting seat is welded on the outer wall of the side surface of the cabinet body. By setting the baffle and the vertical rod, the top of the cabinet body can be protected to prevent the cabinet body from being impacted by external objects from the top. By setting the protection plate, when the two sides of the cabinet body are impacted by external objects, the external objects first contact the protection plate, so that the protection plate absorbs the impact force of the external objects, avoiding the external objects directly impacting the cabinet body. At the same time, when the protection plate is impacted, it moves to the right, driving the support rod to move to the right, so that the support rod squeezes the spring, and through the action of the spring, the impact force from the outside is reduced, improving the protection function of the cabinet body.

[0004] Based on the retrieval of the above patent and the combination with the equipment in the prior art, it is found that when the above equipment is applied, although it can solve the problems that the existing electrical cabinet has a poor protection function, the electrical cabinet is easily damaged by the impact of stones, and the stones are also likely to fall from a high altitude and hit the top of the electrical cabinet, resulting in the deformation of the shell, and in severe cases, the stones may penetrate the electrical cabinet and damage the power equipment inside the electrical cabinet.

[0005] In actual use, it is found that most of the existing electrical cabinets use fans and heat dissipation holes to dissipate the heat generated during the operation of electrical components. This heat dissipation method has a single heat dissipation effect, low heat dissipation efficiency, and when the heat inside the electrical cabinet is low, the fan will still keep running and will not stop automatically, resulting in a waste of electric power resources. Content of the Utility Model

[0006] To solve the problems raised in the above-mentioned background art, the purpose of the present utility model is to provide a heat dissipation device for an electrical cabinet in a construction project, which has the advantage of auxiliary heat dissipation, and solves the problem that most existing electrical cabinets use fans and heat dissipation holes to dissipate the heat generated during the operation of electrical components. This heat dissipation method has a single heat dissipation effect, low heat dissipation efficiency, and when the heat inside the electrical cabinet is low, the fan will still run continuously and will not stop automatically, resulting in a waste of electric power resources.

[0007] To achieve the above purpose, the present utility model provides the following technical solutions: A heat dissipation device for an electrical cabinet in a construction project, including an electrical cabinet body, a cabinet door, and feet. The feet are fixedly connected to the bottom of the electrical cabinet body. There are four feet and they are distributed at the four corners of the bottom of the electrical cabinet body. The cabinet door is movably connected to the front of the electrical cabinet body through hinges. Installation slots are opened on both the left and right sides of the electrical cabinet body. A semiconductor refrigeration sheet is fixedly installed inside the installation slot. The refrigerating surface of the semiconductor refrigeration sheet is fixedly connected to a heat dissipation copper pipe. There are several heat dissipation copper pipes and they are distributed at equal distances. The heat dissipation copper pipes are located inside the electrical cabinet body. A temperature control component is fixedly connected to the top inside the electrical cabinet body.

[0008] Preferably, the temperature control component includes a temperature sensor. The temperature sensor is fixedly connected to the top inside the electrical cabinet body. A controller is fixedly connected to the top at the rear side inside the electrical cabinet body. The controller is electrically connected to the temperature sensor and the semiconductor refrigeration sheet respectively through wires.

[0009] Preferably, placement slots are opened on both the left and right sides inside the electrical cabinet body. There are several placement slots and they are distributed at equal distances. The heat dissipation copper pipes are located inside the placement slots.

[0010] Preferably, a heat dissipation fan is fixedly connected to the heating surface of the semiconductor refrigeration sheet. There are several heat dissipation fans and they are distributed at equal distances.

[0011] Preferably, installation frames are fixedly connected to both the left and right sides of the electrical cabinet body. The heat dissipation fans are located inside the installation frames. A net plate is fixedly connected to the outer side inside the installation frames.

[0012] Preferably, a drain hole is opened at the bottom of the electrical cabinet body.

[0013] Preferably, an observation window is fixedly installed on the front of the cabinet door through a through slot. The material of the observation window is transparent acrylic.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. The utility model solves the problem that most existing electrical cabinets use fans and heat dissipation holes to dissipate the heat generated during the operation of electrical components. This heat dissipation method has a single heat dissipation effect, low heat dissipation efficiency, and when the heat inside the electrical cabinet is low, the fan will keep running and will not stop automatically, resulting in waste of electric power resources. By setting a semiconductor refrigeration sheet, heat dissipation copper tubes, and a temperature control component, a maximum temperature threshold is set inside the temperature control component. When the set threshold is reached, the temperature control component will start the semiconductor refrigeration sheet, so that the refrigerating surface of the semiconductor refrigeration sheet starts to refrigerate. At the same time, the heat dissipation copper tubes on the refrigerating surface will evenly transfer the cold air to various positions of the electrical cabinet body, enabling the inside of the electrical cabinet body to dissipate heat quickly. When the temperature is lower than the set threshold, the temperature control component will turn off the semiconductor refrigeration sheet to avoid wasting electric power resources due to the continuous operation of the semiconductor refrigeration sheet, achieving the effect of auxiliary heat dissipation.

[0016] 2. The utility model sets a temperature control component, enabling the operator to set the threshold of the maximum temperature inside the controller. When the temperature sensor transmits data to the controller through a wire, the controller analyzes the transmitted data. When the analyzed temperature is higher than the set threshold, the controller starts the semiconductor refrigeration sheet for heat dissipation. When the analyzed temperature is lower than the set threshold, the controller will control the semiconductor refrigeration sheet to turn off to avoid wasting electric power resources due to the continuous operation of the semiconductor refrigeration sheet.

[0017] 3. The utility model sets a placement groove, enabling the heat dissipation copper tubes to be placed in the placement groove during installation, avoiding the heat dissipation copper tubes being too protruding after installation and affecting the installation of electrical components.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 3 shown, a heat dissipation device for an electrical cabinet in a building engineering includes an electrical cabinet body 1, a cabinet door 2, and support feet 3. The support feet 3 are fixedly connected to the bottom of the electrical cabinet body 1. There are four support feet 3 and they are distributed at the four corners of the bottom of the electrical cabinet body 1. The cabinet door 2 is movably connected to the front of the electrical cabinet body 1 through a hinge. Installation grooves 4 are opened on both the left and right sides of the electrical cabinet body 1. A thermoelectric cooler 5 is fixedly installed inside the installation groove 4. The cooling surface of the thermoelectric cooler 5 is fixedly connected to a heat dissipation copper tube 6. There are several heat dissipation copper tubes 6 and they are distributed at equal intervals. The heat dissipation copper tubes 6 are located inside the electrical cabinet body 1. A temperature control component 7 is fixedly connected to the top inside the electrical cabinet body 1.

[0024] Referring to Figure 2 , the temperature control component 7 includes a temperature sensor 71. The temperature sensor 71 is fixedly connected to the top inside the electrical cabinet body 1. A controller 72 is fixedly connected to the top of the rear side inside the electrical cabinet body 1. The controller 72 is electrically connected to the temperature sensor 71 and the thermoelectric cooler 5 through wires respectively.

[0025] As a technical optimization solution of the present utility model, by setting the temperature control component 7, the operator sets the threshold of the maximum temperature inside the controller 72. When the temperature sensor 71 transmits data to the controller 72 through a wire, the controller 72 analyzes the transmitted data. When the analyzed temperature is higher than the set threshold, the controller 72 starts the heat dissipation of the thermoelectric cooler 5. When the analyzed temperature is lower than the set threshold, the controller 72 controls the thermoelectric cooler 5 to be turned off, avoiding waste of power resources due to the continuous operation of the thermoelectric cooler 5.

[0026] Referring to Figure 3 , placing grooves 8 are opened on both the left and right sides inside the electrical cabinet body 1. There are several placing grooves 8 and they are distributed at equal intervals. The heat dissipation copper tubes 6 are located inside the placing grooves 8.

[0027] As a technical optimization solution of the present utility model, by setting the placing grooves 8, the heat dissipation copper tubes 6 can be placed in the placing grooves 8 during installation, avoiding the excessive protrusion of the heat dissipation copper tubes 6 after installation and affecting the installation of electrical components.

[0028] Referring to Figure 3, the heating surface of the semiconductor refrigeration sheet 5 is fixedly connected with a heat dissipation fan 9, and a plurality of heat dissipation fans 9 are provided and distributed at equal distances.

[0029] As a technical optimization scheme of the present utility model, by setting the heat dissipation fan 9, the heat dissipation fan 9 and the semiconductor refrigeration sheet 5 are connected to the same power supply. When the semiconductor refrigeration sheet 5 operates, the heat dissipation fan 9 will also operate accordingly, so that the heat generated by the heating surface of the semiconductor refrigeration sheet 5 during operation can be discharged through the heat dissipation fan 9, avoiding the high temperature of the heating surface of the semiconductor refrigeration sheet 5 from affecting the refrigeration effect.

[0030] Reference Figure 3 , mounting frames 10 are fixedly connected to both the left and right sides of the electrical cabinet body 1. The heat dissipation fan 9 is located inside the mounting frame 10, and a net plate 11 is fixedly connected to the outside of the inside of the mounting frame 10.

[0031] As a technical optimization scheme of the present utility model, by setting the mounting frame 10 and the net plate 11, the mounting frame 10 is installed on the left and right sides of the electrical cabinet body 1, and then the net plate 11 is fixedly installed with the mounting frame 10, so that the net plate 11 and the mounting frame 10 shield and protect the exposed fan, avoiding the situation of dust accumulation on the fan.

[0032] Reference Figure 3 , a drain hole 12 is opened at the bottom of the electrical cabinet body 1.

[0033] As a technical optimization scheme of the present utility model, by setting the drain hole 12, during the heat dissipation process of the heat dissipation copper pipe 6 through the semiconductor refrigeration sheet 5, condensed water will be generated on the surface of the heat dissipation copper pipe 6, enabling the condensed water to be discharged through the drain hole 12, avoiding the accumulation of condensed water inside the electrical cabinet body 1.

[0034] Reference Figure 1 , an observation window 13 is fixedly installed on the front surface of the box door 2 through a through groove, and the material of the observation window 13 is transparent acrylic.

[0035] As a technical optimization scheme of the present utility model, by setting the observation window 13 made of transparent acrylic material, the operator can observe the heat dissipation situation inside the electrical cabinet body 1 without opening the box door 2.

[0036] Working principle and usage process of the present utility model: During use, the operator sets the threshold value of the maximum temperature inside the controller 72. When the temperature sensor 71 transmits data to the controller 72 through a wire, the controller 72 analyzes the transmitted data. When the analyzed temperature is higher than the set threshold value, the controller 72 starts the semiconductor refrigeration sheet 5, so that the refrigerating surface of the semiconductor refrigeration sheet 5 starts to refrigerate. At the same time, the heat dissipation copper pipe 6 on the refrigerating surface will evenly transfer the cold air to each position of the electrical cabinet body 1, so that the inside of the electrical cabinet body 1 can quickly dissipate heat. When the inside of the electrical cabinet body 1 dissipates heat to be lower than the set threshold value, the controller 72 will control the semiconductor refrigeration sheet 5 to be turned off to avoid wasting electric power resources due to the continuous operation of the semiconductor refrigeration sheet 5. When the semiconductor refrigeration sheet 5 operates, the heat dissipation fan 9 will also operate accordingly, so that the heat generated on the heating surface during the operation of the semiconductor refrigeration sheet 5 can be discharged through the heat dissipation fan 9, avoiding the high temperature of the heating surface of the semiconductor refrigeration sheet 5 from affecting the refrigeration effect.

[0037] In summary, for the heat dissipation device for a building engineering electrical cabinet, by setting the semiconductor refrigeration sheet 5, the heat dissipation copper pipe 6 and the temperature control component 7, and setting the maximum temperature threshold value inside the temperature control component 7, when the set threshold value is reached, the temperature control component 7 will start the semiconductor refrigeration sheet 5, so that the refrigerating surface of the semiconductor refrigeration sheet 5 starts to refrigerate. At the same time, the heat dissipation copper pipe 6 on the refrigerating surface will evenly transfer the cold air to each position of the electrical cabinet body 1, so that the inside of the electrical cabinet body 1 can quickly dissipate heat. When the temperature is lower than the set threshold value, the temperature control component 7 will turn off the semiconductor refrigeration sheet 5 to avoid wasting electric power resources due to the continuous operation of the semiconductor refrigeration sheet 5, solving the problem that most existing electrical cabinets use fans and heat dissipation holes to dissipate the heat generated during the operation of electrical components. This heat dissipation method has a single heat dissipation effect, low heat dissipation efficiency, and when the heat inside the electrical cabinet is relatively low, the fan will still keep running and will not stop automatically, resulting in waste of electric power resources.
