Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.

The embodiment of the application provides an electric control box assembly which is applied to a window type air conditioner. In order to more clearly illustrate the structure of the electric control box assembly, the electric control box assembly will be described with reference to the accompanying drawings.

Referring to fig. 1, 2 and 3, fig. 1 is a partial structure diagram of a window type air conditioner according to an embodiment of the present application, fig. 2 is a structure diagram 1 of a box body shown in fig. 1, and fig. 3 is a structure diagram 2 of the box body shown in fig. 1. The embodiment of the present application provides an electric control box assembly 40, which is applied to a window type air conditioner 100, wherein the window type air conditioner may be a cylinder type air conditioner, a box type air conditioner, etc., and the application is illustrated by taking the box type air conditioner as an example. The window air conditioner 100 includes a partition 30, and an electric control box assembly 40 is mounted to the partition 30. The electronic control box assembly 40 comprises a box body 41, the box body 41 is provided with an accommodating space, and the electronic control box assembly 40 comprises a plurality of functional devices, and the accommodating space is used for accommodating the functional devices. Specifically, referring to fig. 4 in conjunction with fig. 2 and 3, fig. 4 is a structural diagram 3 of the case shown in fig. 1. The box 41 is further provided with an air inlet channel 411 and an air outlet channel 412, which are communicated with the accommodating space, the air inlet channel 411 includes a first inlet 4113 and a first outlet 4114, wherein the first inlet 4113 is larger than the first outlet 4114, the air outlet channel 412 includes a second inlet 4123 and a second outlet 4124, and the second inlet 4123 is larger than the second outlet 4124. The partition board 30 is provided with a fan 31, air flows into the air inlet channel 411, heat exchange is performed on functional devices in the electric control box assembly 40, and cool air subjected to heat exchange flows out of the air outlet channel 412 under the action of negative pressure due to the fact that the fan 31 is driven by the motor to generate a negative pressure area. The airflow path for radiating the electric control box assembly 40 is as follows: the first inlet 4113-the first outlet 4114-the electric control box housing space-the second inlet 4123-the second outlet 4124-the fan 31, according to bernoulli's principle, increases in velocity and decreases in pressure as the fluid passes through the conduit or a narrow area of the conduit. Since the first inlet 4113 is larger than the first outlet 4114 and the second inlet 4123 is larger than the second outlet 4124, a negative pressure is generated in the air inlet channel 411 along with the high-speed air flow entering the first outlet 4114, so that the air flow is forced to be injected into the box 41 from the first outlet 4114 and quickly flows out from the second outlet 4124. Compared with the traditional electric control box with the same air inlet and air outlet, the air inlet channel 411 and the air outlet channel 412 provided by the application can effectively improve the air flow rate, increase the heat exchange speed and improve the drying efficiency.

Illustratively, a first groove 4111 is formed in the bottom of the box 41 near a side of the first air inlet plate 21, the box 41 includes a first groove end wall 4118 and two first groove side walls 4117 that form the first groove 4111, the first groove end wall 4118 is provided with the first outlet 4114, the first groove side walls 4117 are respectively disposed at two ends of the first groove end wall 4118, the two first groove side walls 4117 are disposed in parallel, and the box 41 is further formed with a first notch, and the first notch is disposed opposite to the first groove end wall 4118.

Illustratively, the box 41 further includes first guiding structures 4112 disposed on two sides of the first groove 4111, and each of the first guiding structures 4112 and one of the first groove sidewalls 4117 form the air inlet channel 411. Because the first guiding structure 4112 is disposed in the first groove 4111, the air inlet channel 411 is formed by using the first guiding structure 4112 and the first groove sidewall 4117, and compared with the second guiding structure 4122 disposed on the side or the top of the box body 41, the space utilization rate can be improved while the air inlet effect is ensured.

Illustratively, each of the first flow directing structures 4112 includes a first flow directing segment 4115 and a first flow restricting segment 4116 connected to each other, the first flow directing segment 4115 being disposed at an end distal from the first outlet 4114, the first flow restricting segment 4116 being disposed at an end proximal to the first outlet 4114, the first flow directing segment 4115 and a first channel sidewall 4117 proximal to the first flow directing structure 4112 forming a first flow restricting angle, the first flow restricting segment 4116 and a first channel sidewall 4117 proximal to the first flow directing structure 4112 forming a first flow restricting angle, the first flow restricting angle being greater than the first flow restricting angle. As shown, the first drainage segment 4115 and the first groove sidewall 4117 form a first drainage angle a, the first flow restricting segment 4116 and the first groove sidewall 4117 form a first flow restricting angle b, and the first drainage angle a is greater than the first flow restricting angle b due to the fact that the first drainage segment 4115 and the first flow restricting segment 4116 are arranged obliquely with different slopes (because the structures of the first flow restricting segments 4112 on two sides are the same structure, the first flow restricting angle b is marked on the other side in the figure for clarity of explanation). For example, the angle of the first conduction angle a may be between 35 ° and 40 °, and the inclination angle of the first restriction angle b may be between 15 ° and 20 °. After entering the accommodating space through the air inlet channel 411, cool air diffuses and exchanges heat to large components such as an inductor and a capacitor, and then the cool air is brought out by utilizing the negative pressure effect. In the present application, the first drain segment 4115 and the first slot sidewall 4117 form a substantially trumpet-shaped drain channel to direct more wind flow from the first inlet 4113 into the receiving chamber. And the first restriction 4116 and the first slot sidewall 4117 form a more narrow restriction passage, since the first draft angle a is greater than the first restriction angle b and the draft passage tapers in a direction from the inner radial receiving chamber of the restriction passage. When the wind flow passes through the flow limiting channel, the speed of the wind flow is increased, the pressure of the wind flow is reduced, and the wind flow pushes the fluid to continuously flow into the accommodating cavity rapidly and exchange heat with the heating element. Therefore, when the air flow enters the accommodating chamber from the air inlet channel 411, the air inlet channel 411 can quickly guide more air flow to the heating element, so that a better heat dissipation effect is realized on the heating element.

Because the second flow guiding structure 4122 is disposed in the second groove 4121, the air outlet channel 412 is formed by using the second flow guiding structure 4122 and the side wall of the second groove, and compared with the second flow guiding structure 4122 disposed at other positions of the box 41, the air outlet channel 412 can be closer to the fan, so as to accelerate the heat exchange efficiency.

Illustratively, the first outlet 4114 is disposed at two ends of the first slot end wall 4118, the first guiding structures 4112 are disposed at two sides of the first slot 4111, and each of the first guiding structures 4112 and one of the first slot side walls 4117 form two of the air inlet channels 411. The second inlet 4123 is disposed at two ends of the second slot end wall, the second flow guiding structures 4122 are disposed at two sides of the second groove 4121, and each of the second flow guiding structures 4122 and one of the second slot side walls form two air outlet channels 412. In some embodiments, the first outlet 4114 may be disposed at one end of the first slot end wall 4118, and the first flow guiding structure 4112 is disposed at one side of the first outlet 4114 to form an air inlet channel 411. Similarly, the second outlet 4124 may be disposed at one end of the second slot end wall, and the second flow guiding structure 4122 is located at one side of the second outlet 4124 to form an air outlet channel 412. When the heating element is disposed at two ends of the first slot end wall 4118 or the second slot end wall, the number of the air inlet channels 411 or the air outlet channels 412 may be two, and when the heating element is disposed at one end of the first slot end wall 4118 or the second slot end wall, the number of the air inlet channels 411 or the air outlet channels 412 may be one, and a person skilled in the art may set specific positions of the first diversion structure 4112 and the second diversion structure 4122 at the positions of the heating element, and change the number of the air inlet channels 411 and the air outlet channels 412, and the present application is not limited herein.

Illustratively, the inner diameter of the outlet air passage 412 is inversely proportional to the distance of the outlet air passage 412 from the second inlet. The second flow directing structure 4122 and the second slot sidewall remote from the second flow directing structure 4122 form a flow directing angle, which may be 55 ° -60 °. In some embodiments, each of the second flow guiding structures 4122 may include a second flow guiding section and a second flow limiting section connected to each other, where the second flow guiding section and a second groove sidewall far from the second flow guiding section form a second flow guiding angle, and the second flow limiting section and a second groove sidewall far from the second flow limiting section form a second flow limiting angle, and the size of the second flow limiting angle and the second flow limiting angle may be set by those skilled in the art according to the actual situation, and the present application is not limited herein.
