Detailed Description

Embodiments of the present utility model will be described in detail below, by way of example with reference to the accompanying drawings.

An air conditioner according to an embodiment of the present utility model is described below with reference to fig. 1 to 12.

An air conditioner includes: casing, compressor, outdoor heat exchanger and outdoor fan.

The shell is internally provided with an air duct communicated with the outside, the compressor, the outdoor heat exchanger and the outdoor fan are arranged in the air duct, and the outdoor fan drives air flow to enter the air duct to exchange heat with the outdoor heat exchanger and then flow to the outside. Because the compressor, the outdoor heat exchanger, the outdoor fan and the like can emit larger noise when in working operation, and are the sources of main noise in the air conditioner, the compressor, the outdoor heat exchanger and the outdoor fan are arranged in the shell, and the noise can be isolated from the indoor environment, so that the indoor mute effect is realized, and the use experience of a user is improved.

The outdoor fan can be an axial flow fan, and the compressor is connected with the outdoor heat exchanger through a refrigerant pipe.

When the air conditioner works, the outdoor fan rotates, external air flows into the air duct through the outdoor air inlet under the drive of the outdoor fan and exchanges heat with the outdoor heat exchanger, the external air flows are converted into hot air or cold air and then are output by the outdoor air outlet, and in the process that the air flows to the outdoor air outlet, the flowing air flows can also take away heat generated by the compressor.

The air conditioner further includes: the automatically controlled box subassembly sets up on the casing, and automatically controlled box subassembly includes: the electronic control module and the electronic control box 100 are arranged in the electronic control box 100. By the arrangement, the electronic control module is arranged in the electronic control box 100, so that the electronic control module can be protected from being interfered by external environment, and the normal operation of the electronic control module is ensured.

Wherein, the electronic control module is electrically connected with the outdoor fan and the compressor. The electric control module can control the starting and stopping of the outdoor fan and the starting and stopping of the compressor, so that the normal operation of the air conditioner can be ensured.

Specifically, the electronic control module may include a circuit board fixedly installed in the electronic control box 100 and a control device disposed on the circuit board.

The control device may be a capacitor, resistor or the like for realizing circuit control, and the circuit board may be a Printed Circuit Board (PCB), and reference may be made to an electronic control module in the prior art for specific structures and electronic control principles of the control device and the circuit board.

In addition, as shown in fig. 11-12, the electric control box 100 is provided with an inner cavity, a heat dissipation air inlet communicated with the inner cavity is formed on the electric control box 100, and a heat dissipation space is formed between the inner wall of the inner cavity and the heat dissipation air inlet. So set up, automatically controlled box 100 has the inner chamber that holds automatically controlled module to be formed with the heat dissipation air intake that is linked together with the inner chamber on the automatically controlled box 100, so that the inner wall of inner chamber and the space between the heat dissipation air intake form the heat dissipation space, are used for dispelling the heat to automatically controlled module.

As shown in fig. 1 to 6, the electronic control box 100 includes: an air intake assembly, the air intake assembly comprising: a first air inlet plate 1 and a second air inlet plate 2. In other words, the first air inlet plate 1 and the second air inlet plate 2 form part of the electronic control box 100 and are used to allow external air flow through the first air inlet plate 1 and the second air inlet plate 2 into the interior cavity.

The first air inlet plate 1 is provided with a plurality of first air inlet holes 11, the second air inlet plate 2 is provided with a plurality of second air inlet holes 21, and the first air inlet holes 11 and the second air inlet holes 21 form a heat dissipation air inlet. So set up, be equipped with a plurality of first fresh air inlets 11 on the first fresh air inlet 1, be equipped with a plurality of second fresh air inlets 21 on the second fresh air inlet 2 to make outside air current get into in the heat dissipation space of automatically controlled box 100 through first fresh air inlet 11 and second fresh air inlet 21, thereby take away the produced heat of automatically controlled module, realize the radiating effect.

The first air inlet plate 1 is perpendicular to the horizontal plane, the second air inlet plate 2 is connected to the lower portion of the first air inlet plate 1, the second air inlet plate 2 is obliquely arranged towards the inner cavity, and an obtuse angle is formed between the second air inlet plate 2 and the first air inlet plate 1. When external air flows enter the inner cavity from the plurality of first air inlet holes 11 and the plurality of second air inlet holes 21, an obtuse angle is formed between the second air inlet plate 2 and the first air inlet plate 1, so that the air flow entering the inner cavity from the first air inlet plate 1 and the air flow entering the inner cavity from the second air inlet plate 2 form turbulence in the space adjacent to the air inlet side of the inner cavity, the temperature of wind can be effectively reduced, and the heat of the inner cavity is brought out of the electric control box 100 by the wind, so that the heat dissipation effect on the electric control module is realized; and, after the rainwater enters the inner cavity from the first air inlet holes 11 and the second air inlet holes 21, the rainwater entering the inner cavity from the first air inlet plate 1 and the rainwater entering the inner cavity from the second air inlet plate 2 form convection in the space adjacent to the air inlet side of the inner cavity, so that most of the rainwater can fall on the bottom of the electric control box 100, and the electric control module cannot be affected.

In addition, the second air inlet plate 2 is obliquely arranged, so that rainwater entering the inner cavity can flow down smoothly and be discharged along with the rainwater.

Compared with the prior art, the air inlet is mostly directly in and out, and is generally designed into a shutter shape for preventing rainwater from entering, so that the heat dissipation and the rain prevention effect are poor. The air inlet component of the utility model can not only preferentially reduce the temperature of wind entering the inner cavity so as to better realize the heat dissipation requirement on the electric control module, but also enable the rainwater entering the electric control box 100 to fall at the bottom of the electric control box 100 and be discharged along with the rainwater, thus not directly impacting the electric control module and effectively ensuring the electricity safety and the service life of the electric control module.

Therefore, by arranging the air inlet component on the air inlet side of the electric control box 100 so that a connection structure with an obtuse angle is formed between the first air inlet plate 1 and the first air inlet plate 1, on one hand, when external air flow enters the inner cavity through the plurality of first air inlet holes 11 and the plurality of second air inlet holes 21, turbulence is formed between the air flow entering the inner cavity from the first air inlet plate 1 and the air flow entering the inner cavity from the second air inlet plate 2 in the space adjacent to the air inlet side of the inner cavity, the temperature of wind can be effectively reduced, and therefore, the heat of the inner cavity is brought out of the electric control box 100 by wind, and the heat dissipation effect on the electric control module is realized; on the other hand, after the rainwater enters the inner cavity from the first air inlet holes 11 and the second air inlet holes 21, the rainwater entering the inner cavity from the first air inlet plate 1 and the rainwater entering the inner cavity from the second air inlet plate 2 form convection in the space adjacent to the air inlet side of the inner cavity, so that most of the rainwater can fall on the bottom of the electric control box 100 adjacent to the air inlet side and is discharged out along with the bottom, the electric control module cannot be directly impacted, and the electricity utilization safety and the service life of the electric control module are effectively ensured.

According to some embodiments of the present utility model, the second air inlet plate 2 is provided with a drainage portion 22, the drainage portion 22 is disposed on a side of the second air inlet plate 2 away from the first air inlet plate 1, and the drainage portion 22 is located below the plurality of second air inlet holes 21. Referring to fig. 2 to 4, a drainage part 22 is arranged at one side of the second air inlet plate 2 far away from the first air inlet plate 1, and the rainwater entering the inner cavity from the first air inlet plate 1 and the rainwater entering the inner cavity from the second air inlet plate 2 form convection in the space adjacent to the air inlet side of the inner cavity, so that most of the rainwater can fall on the bottom of the electric control box 100 adjacent to the air inlet side and is directly discharged from the drainage part 22, and the rainwater cannot be accumulated in the electric control box 100, thereby effectively ensuring the electricity safety and the service life of the electric control module.

According to some embodiments of the utility model, the air intake component further comprises: the bottom plate is horizontally arranged at the bottom of the electric control box 100, the bottom plate is connected below the second air inlet plate 2, and a water draining part 22 is arranged at one side of the bottom plate adjacent to the second air inlet plate 2. So set up, can make the majority rainwater that gets into the inner chamber drop on the bottom plate to directly discharge away through drainage portion 22, and, the area that the bottom plate set up is bigger, can prevent rainwater invasion to electric control module's position better.

In some embodiments, the drainage portion 22 may be a drainage groove extending along the length direction of the second air inlet plate 2, and the drainage groove may have a length dimension equal to or greater than the length dimension of the plurality of first air inlet holes 11 and the plurality of second air inlet holes 21. Referring to fig. 2-4, the drainage groove is in a strip shape, when rainwater entering from the first air inlet hole 11 and the second air inlet hole 21 flows down in a homeotropic manner, rainwater can be effectively prevented from flowing to the bottom of the electric control box 100 and cannot be discharged in time, the risk that rainwater is accumulated at the bottom of the electric control box 100 is greatly reduced, and the electricity safety of the electric control module is further ensured.

Referring to fig. 7 to 10, the first air inlet hole 11 and/or the second air inlet hole 21 are tapered holes, each tapered hole has a large hole end 3 and a small hole end 4, the large hole end 3 is arranged on the air inlet side of the electronic control box 100, the small hole end 4 is arranged on the inner wall side of the electronic control box 100, and an air flow channel 5 is formed between the large hole end 3 and the small hole end 4.

First, it is to be understood what is the "Bernoulli principle", essentially the conservation of mechanical energy of the fluid.

Namely: kinetic energy + gravitational potential energy + pressure potential energy = constant, when the fluid is flowing at equal height, the velocity of flow is big, and pressure is little. When the fluid enters from the end with large aperture and exits from the end with small aperture, the flow velocity of the fluid becomes large, and when the gas flows to the small aperture through the large aperture, the pressure at two sides is different, because the gas is influenced by air resistance in the flowing process, thereby causing pressure variation.

The Bernoulli principle is adopted, namely, the relation between the pressure and the speed is related in the fluid flowing process, and when the gas flows from the big hole to the small hole, the pressure is reduced as the speed of the gas is increased. In addition, hong Ji's law in fluid mechanics can also be adopted, namely, in the fluid flowing process, the relation between the pressure and the flow rate is interrelated, and when the gas flows from the big hole to the small hole, the pressure is reduced along with the flow rate of the gas, and the temperature is also reduced along with the flow rate of the gas.

According to the Bernoulli principle and Hong Ji law, the first air inlet hole 11 and/or the second air inlet hole 21 are designed to be conical holes, on one hand, when external air flow enters from the big hole end 3 of the conical holes and enters the inner cavity from the small hole end 4 of the conical holes through the air flow channel 5, the temperature of wind can be effectively reduced, so that the heat of the inner cavity is brought out of the electric control box 100 by utilizing the wind with relatively low temperature, and the heat dissipation effect on the electric control module is better realized. On the other hand, when the rainwater is sputtered on the first air inlet plate 1 and the second air inlet plate 2, the design of the conical holes can better prevent the rainwater from entering the inner cavity, and the rainwater entering the inner cavity can better promote the convection effect under the action of the conical holes, so that most of the rainwater is reduced at the bottom of the electric control box 100, and is discharged out of the electric control box 100 through the water discharge part 22, and the air inlet and rain requirements of the electric control box 100 are better met.

In some embodiments, the pore size of macroporous end 3 is r1 and the pore size of macroporous end 4 is r2, r1 and r2 satisfying the relationship: r1 is more than or equal to 1.2r2. In other words, the aperture of the macroporous end 3 is more than 1.2 times that of the aperture of the microporous end 4, so that the pressure intensity of the external air flow flowing to the microporous end 4 through the macroporous end 3 can be obviously changed, and the temperature of the external air flow can be obviously reduced, so that the relatively low-temperature air belt can carry away heat in the electric control box 100, and a better heat dissipation effect is realized.

In the embodiment of the utility model, the aperture of the large pore end 3 is 6.0mm, the aperture of the small pore end 4 is 2.27mm, and the airflow passage 5 is 4mm.

Experiments prove that the air conditioner normally operates at the outdoor environment temperature of 52 ℃, and the IPM temperature of a control device in the electric control module is detected to be 71 ℃ so as to meet the requirement of being lower than 85 ℃. In addition, in the rain experiment process, hidden danger that rainwater enters the electric control box 100 does not occur, and the rainwater is effectively blocked outside the electric control box 100.

In some embodiments, the obtuse angle formed between the second air intake plate 2 and the first air intake plate 1 is α, which satisfies the relationship: alpha is more than or equal to 120 degrees. The arrangement is that the obtuse angle alpha formed between the second air inlet plate 2 and the first air inlet plate 1 is more than or equal to 120 degrees, the requirement of air inlet cooling can be well met, turbulent flow is formed between the air flow entering the inner cavity from the first air inlet plate 1 and the air flow entering the inner cavity from the second air inlet plate 2 at the space position adjacent to the air inlet side of the inner cavity, and accordingly the heat of the inner cavity is brought out of the electric control box 100 by utilizing wind. And the rainwater entering the inner cavity from the first air inlet plate 1 and the rainwater entering the inner cavity from the second air inlet plate 2 form convection in the space adjacent to the air inlet side of the inner cavity, so that most of the rainwater is ensured to fall at the bottom of the electric control box 100 adjacent to the air inlet side and is discharged along with the bottom, the electric control module cannot be directly impacted, and the electricity safety and the service life of the electric control module are effectively ensured.

In the embodiment of the utility model, an included angle with alpha being 128 degrees is formed between the second air inlet plate 2 and the first air inlet plate 1, so that the requirements of air inlet and rain of the electric control box 100 can be met at the same time.

So set up, correspond first fresh air inlet 11 and second fresh air inlet 21 at length direction setting, can make the air current that gets into first fresh air inlet 11 and the turbulent flow that gets into second fresh air inlet 21 formation effectual, do benefit to better to reduce the temperature of wind to utilize the heat of wind with the inner chamber to take out automatically controlled box 100, realize the radiating effect to electric control module.

Of course, the first air inlet holes 11 and the second air inlet holes 21 can also be distributed in a staggered manner in the length direction, and the temperature of wind can be effectively reduced, so that the heat dissipation effect on the electronic control module is ensured.

In some embodiments, the air intake component further comprises: the side plates 6, the side plates 6 are respectively connected to two ends of the first air inlet plate 1 and the second air inlet plate 2, and the side plates 6 are arranged towards the inner cavity so as to form an air inlet cavity 7 at the heat dissipation air inlet with the first air inlet plate 1 and the second air inlet plate 2. So set up, connect curb plate 6 at the both ends of first aviation baffle 1 and second aviation baffle 2 to be located the inner wall one side of inner chamber at the heat dissipation air intake and form air inlet chamber 7, make air intake part form a whole air inlet structure, be connected with the automatically controlled box 100 that has the air inlet breach through curb plate 6, thereby match automatically controlled box 100 of different models according to air inlet and rain requirement.

Of course, the design of the side plate 6 can be omitted, so that the two ends of the first air inlet plate 1 and the second air inlet plate 2 are directly connected with other parts of the electric control box 100, and the air inlet cavity 7 can be formed on one side of the inner wall of the inner cavity of the heat dissipation air inlet, thereby effectively reducing the temperature of wind, realizing the heat dissipation effect on the electric control module, and most of rainwater can fall at the bottom of the air inlet cavity 7 of the electric control box 100 and be discharged out along with the bottom of the air inlet cavity, so that the electricity safety and the service life of the electric control module are effectively ensured.

In addition, the electronic control box assembly includes: the radiator is arranged in the electric control box 100 and connected with the electric control module for radiating the electric control module. So set up, under the design of heat dissipation air intake to combine the heat dissipation effect of radiator, can reduce electric control module's operating temperature effectively, effectively prolong electric control module's life.

For example, the heat sink may be disposed on a relatively powerful component of the electronic control module, and the heat sink may include a plurality of heat sinks for effectively dissipating heat from the electronic control module.

And, the electronic control box assembly includes: the electronic control housing is arranged outside the electronic control module, and is connected with the electronic control box 100.

In addition, a heat dissipation air outlet is further arranged on the electric control box 100, external air flows into the inner cavity from the heat dissipation air inlet, and heat generated by carrying the electric control module flows out from the heat dissipation air outlet.
