Description

Technical Field

[0001] The present invention relates to the technical field of smart building controllers, and in particular to a heat dissipation type DDC controller for smart buildings. Background Art

[0002] Building automation refers to the electrical equipment in the building, such as elevators, water pumps, fans, air conditioners, etc., whose main working nature is strong electric drive. Usually these devices are in an open working state, that is, there is no closed loop. As long as the power is turned on, the equipment is working. As for the working status, process, energy consumption, etc., it is impossible to get data online in a timely manner, let alone reasonable use and energy conservation. Now building automation is to monitor the above-mentioned electrical equipment online, by setting corresponding sensors, travel switches, photoelectric controls, etc., to detect the working status of the equipment, and return it to the central computer in the control room through the line and DDC controller. The computer obtains the analysis results and then returns them to the equipment terminal for mediation.

[0003] The smart building controller will generate a certain amount of heat during operation. If the heat cannot be dissipated in time, the internal temperature of the controller will rise, which may cause overheating and damage to electronic components.

[0004] In the prior art, a cooling fan is usually arranged in the DDC controller, an air inlet is provided at one end of the shell of the DDC controller, and an air outlet is provided at the other end. The cooling fan sucks outside air into the shell through the air inlet and then discharges it through the air outlet, thereby accelerating the air flow in the shell to dissipate heat and cool the internal structure of the DDC controller. In actual application, since the DDC controller is installed in a building, dust from the outside can easily enter the shell, thereby affecting the normal operation of the internal components of the DDC controller. Although filters are currently provided at the air inlet and the air outlet to block dust, the dust also needs to be cleaned regularly, otherwise the filter is easily blocked, and the cleaning process is relatively cumbersome.

[0030] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] It should be noted that all directional indications in the embodiments of the present invention (such as up-down-left-right-front-back...) are only used to explain the relative position relationship - movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0033] Example 1

[0034] like Figure 1-Figure 5 As shown, a heat dissipation DDC controller for smart buildings includes a controller body 1, an air inlet box 104 is arranged at the bottom of the controller body 1, an air inlet 105 is opened at the air inlet box 104, and a filter component is arranged at the air inlet 105 to filter the air entering the air inlet box 104; specifically, in this embodiment, when the DDC controller is dissipated, the outside air can first enter the air inlet box 104 through the air inlet 105, and then enter the controller body 1 from the air inlet box 104 to perform heat dissipation and cooling.

[0035] See also Figure 5-Figure 6 An air outlet box 103 is provided on the controller body 1, an air outlet 2 is provided on the air outlet box 103, a first filter plate 201 is embedded in the air outlet 2, and first filter holes 202 are evenly provided on the first filter plate 201; specifically, in this embodiment, the first filter plate 201 and the first filter holes 202 are provided at the air outlet 2 to prevent dust in the outside air from falling into the controller body 1 through the air outlet 2; correspondingly, since the air outlet 2 is in an air outlet state, an impact force can be applied to the filter holes 202, and it is difficult for the outside dust to adhere to the first filter holes 202.

[0036] A cooling box 107 is provided on one side of the controller body 1 close to the air inlet box 104, and the cooling box 107 is connected to the air inlet box 104, wherein an air cooling component is provided in the cooling box 107 for drawing outside air from the air inlet box 104 into the cooling box 107, and a plurality of groups of air ducts 106 are arranged on both sides of the cooling box 107, and the other end of the air duct 106 is connected to the air outlet box 103; it can be explained that after the air cooling component of this embodiment draws outside air into the cooling box 107, it can continue to be transported to the air outlet box 103 along the air ducts 106, and finally discharged from the air outlet 2. Since the cooling box 107 and the air duct 106 are both arranged on the periphery of the components in the controller body 1, the wind can cool the components synchronously during the transportation process, thereby improving the heat dissipation effect.

[0037] In this embodiment, a dust removal component is also included, and the dust removal component is used to remove dust attached to the surface of the filter component;

[0038] The working principle of this embodiment is as follows: before the outside air enters the air inlet box 104, it first needs to pass through the filter component, and the impurity particles in the dust are filtered through the filter component. After the filter component has been used for a period of time, this embodiment can clean the dust attached to the surface of the filter component through the dust removal component to avoid excessive dust adhesion and affect the normal filtering effect of the filter component. This embodiment does not require manual regular cleaning, which can effectively extend the service life of the smart building DDC controller and improve stability.

[0039] Example 2

[0040] Based on Example 1, please refer to Figure 3-Figure 6 The filter assembly includes through slots 108 symmetrically opened on the two side walls of the air inlet box 104, the through slots 108 are opened on the side close to the air inlet 105, the filter assembly also includes a second filter plate 301 slidably embedded in the through slots 108 on both sides, one end of the second filter plate 301 is slidably connected to the third filter plate 3, wherein the second filter plate 301 and the third filter plate 3 are evenly provided with second filter holes 302, the second filter plate 301 and the third filter plate 3 are connected to a driving module that drives them to reciprocate along the through slots 108; it can be explained that the second filter plate 301 and the third filter plate 3 in this embodiment have the same size, when the second filter plate 301 or the third filter plate 3 slides to the air inlet 105, it can completely cover the air inlet 105, thereby achieving the effect of filtering dust;

[0041] Correspondingly, after the second filter plate 301 or the third filter plate 3 has been used for a period of time, the second filter plate 301 and the third filter plate 3 are driven by the driving module to slide along the through groove 108. For example, in the initial state, the second filter plate 301 and the third filter plate 3 are driven by the driving module to slide along the through groove 108. Figure 2The second filter plate 301 is in a state of being embedded in the air inlet 105. After filtering for a period of time, the second filter plate 301 is driven by the driving module to slide toward one side of the air inlet box 104, so that the third filter plate 3 can be embedded in the air inlet 105 for filtering, and the second filter plate 301 and the third filter plate 3 are used alternately in this way to avoid the phenomenon of the second filter hole 302 being blocked due to the long-term use of a group of filter plates.

[0042] In the present embodiment, two groups of T-shaped grooves 306 are symmetrically provided on one side of the third filter plate 3 close to the second filter plate 301, and a T-shaped slide seat 307 slidably connected to the T-shaped groove 306 is correspondingly fixedly arranged on the side of the second filter plate 301 close to the third filter plate 3; it can be explained that in the present embodiment, the third filter plate 3 is slidably connected to the second filter plate 301 by setting the T-shaped slide seat 307 and the T-shaped groove (306), and when the third filter plate 3 or the second filter plate 301 is driven to vibrate, no interference phenomenon will occur.

[0043] The driving module includes a driving mechanism 4 fixedly arranged at the bottom of the controller body 1, the driving end of the driving mechanism 4 is fixed to two groups of U-shaped frames 401, and a guide rod 303 is fixedly arranged at one end of the U-shaped frame 401 away from the driving mechanism 4, wherein a support 304 slidably connected to the guide rod 303 is fixedly arranged on one side of the third filter plate 3 and the second filter plate 301, and telescopic springs 305 are arranged on both sides of the guide rod 303, one end of the telescopic spring 305 is fixed to the U-shaped frame 401, and the other end is fixed to the support 304; it can be explained that when the third filter plate 3 and the second filter plate 301 are driven to slide, the U-shaped frames 401 on both sides are first driven to slide by the driving mechanism 4, and the U-shaped frames 401 can drive the third filter plate 3 and the second filter plate 301 to move through the guide rod 303 and the support 304, and the telescopic spring 305 is provided in the present embodiment to limit the support 304 so that the support 304 can be kept in the middle position of the guide rod 303.

[0044] The dust removal assembly includes two sets of vibration motors 403 fixedly arranged at the bottom of the controller body 1; specifically, when the third filter plate 3 or the second filter plate 301 is offset to the side of the air inlet box 104, it is just located on the driving end side of the vibration motor 403, and then the filter plate on this side can be vibrated by starting the vibration motor 403 to make the dust impurities attached to the second filter hole 302 fall off. During the vibration process, the support 304 on one side slides on the guide rod 303, and can be driven to reset by the telescopic spring 305.

[0045] Correspondingly, the driving mechanism 4 of this embodiment can adopt a screw-nut transmission mechanism, a gear rack transmission mechanism or a synchronous belt transmission mechanism, which is not limited in this embodiment, so as to actually drive the U-shaped frames 401 on both sides to move in a straight line.

[0046] Furthermore, the air cooling component includes an electric motor 404 fixedly arranged in the air inlet box 104, the driving end of the electric motor 404 is fixed to the impeller 405, and a plurality of groups of blades are fixedly arranged in a circumferential array on the impeller 405; it can be explained that during the air cooling process, the electric motor 404 is started to drive the impeller 405 to rotate, and during the rotation of the impeller 405, the outside air can be sucked into the air inlet box 104 and blown toward the air outlet box 103.

[0047] Furthermore, a water cooling pipe 402 is arranged on the side of the impeller 405 away from the air inlet box 104, and the water cooling pipe 402 is connected to the liquid storage tank through the pump body; it can be explained that in order to further improve the heat dissipation efficiency, the coolant can be stored in the liquid storage tank, and the pump body can extract the coolant in the liquid storage tank and transport it to the water cooling pipe 402, so as to further reduce the temperature of the air input into the air inlet box 104 and improve the subsequent cooling efficiency. At the same time, the coolant in the water cooling pipe 402 can flow back to the liquid storage tank to achieve a circulating cooling effect.

[0048] In this embodiment, a plurality of groups of connection terminals 101 are evenly arranged on one side of the controller body 1 for connecting control circuits.

[0049] Among them, two groups of mounting seats 102 are symmetrically fixedly arranged on the bottom of the controller body 1 for mounting and fixing the controller body 1.

[0050] The working principle of this embodiment is: in the initial state, you can refer to Figure 2 , the second filter plate 301 is in a state of being embedded in the air inlet 105. After filtering for a period of time, the second filter plate 301 is driven by the driving module to slide toward one side of the air inlet box 104, so that the third filter plate 3 can be embedded in the air inlet 105 for filtering, and so on. The second filter plate 301 and the third filter plate 3 are used alternately to avoid the phenomenon of second filter hole 302 being blocked due to long-term use of a group of filter plates. When the third filter plate 3 or the second filter plate 301 deviates to one side of the air inlet box 104, it is just located at the driving end side of the vibration motor 403 at this time, and then the filter plate on this side can be vibrated by starting the vibration motor 403 to make the dust and impurities attached to the second filter hole 302 fall off. During the vibration process, the support 304 on one side slides on the guide rod 303, and can be driven to reset by the telescopic spring 305.

[0051] The parts not involved in this technical solution can be implemented by using existing technologies.
