Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
In order to solve the technical problem that the cooling mode of the electrical box is not good in the air supply equipment in the prior art, the heat of the electrical box can be effectively dissipated, and the electrical safety of the electrical box is prevented from being damaged by condensation on the electrical box. As shown in fig. 1, 2 and 3, the air supply apparatus of the present invention includes a case 10, an evaporator 20, a wind power part 30 and an electrical box 40. A refrigerating air cavity a and a heat dissipation air cavity b which are separated from each other are formed in the shell 10, an air inlet 11 and an air outlet 12 which are communicated with the refrigerating air cavity a are formed in the shell 10, an air return opening 13 which is communicated with the heat dissipation air cavity b is further formed in the shell 10, and the heat dissipation air cavity b is communicated with the refrigerating air cavity a through a communication opening 14. The evaporator 20 and the wind power part 30 are installed in the cooling wind chamber a, and the electric box 40 is installed in the cooling wind chamber b.
By applying the technical scheme of the invention, on the basis of the refrigerating air cavity a, the heat dissipation air cavity b is additionally arranged at intervals and is communicated with the refrigerating air cavity a through the communication port 14. When the wind power component 30 works in the refrigerating air cavity a, the refrigerating air cavity a generates negative pressure, on one hand, airflow is introduced through the air inlet 11 to enable the evaporator 20 to adjust the temperature and then blown out from the air outlet 12, on the other hand, the negative pressure of the refrigerating air cavity a also acts on the heat dissipation air cavity b through the communication port 14, the airflow enters the heat dissipation air cavity b from the air return port 13 and then is discharged to the refrigerating air cavity a from the communication port 14, and the airflow dissipates heat of the electrical box 40. Since the electrical box 40 is not in the same cavity as the evaporator 20, the electrical box 40 does not condense due to too low a temperature.
As a preferred embodiment, as shown in fig. 1, the return air inlet 13 and the outlet 12 are opened on the same side of the housing 10. Therefore, the air flow with lower temperature blown out from the air outlet 12 can be introduced into the air return opening 13, and the influence of the over-high temperature of the electrical box 40 on the use can be effectively prevented.
As shown in fig. 3, in the present embodiment, the communication port 14 is opposed to the evaporator 20. Therefore, the air heated by the electrical box 40 can be cooled by the evaporator 20 again, and the energy efficiency is effectively improved.
In manufacturing, two sheet metal cavities are typically fabricated to mount the evaporator 20 and the wind power component 30, respectively. As shown in fig. 2, in the solution of the present embodiment, the refrigerated air chamber a includes a first air chamber a1 and a second air chamber a2 that are communicated with each other, the evaporator 20 is installed in the first air chamber a1, the wind power component 30 is installed in the second air chamber a2, and the communication port 14 is communicated with the first air chamber a 1. Optionally, the second air cavity a2 and the heat dissipation air cavity b are arranged side by side, and the first air cavity a1 is parallel to the second air cavity a2 and the heat dissipation air cavity b.
As another alternative, the cooling air chamber a may be manufactured as a single body without distinguishing the first air chamber a1 from the second air chamber a 2.
As shown in fig. 3 and 4, in the solution of the present invention, the evaporator 20 is opposite to the air inlet 11, and the wind power component is opposite to the air outlet 12. In use, as the wind power component 30 operates to make the pressure in the second wind chamber a2 less than the atmospheric pressure, the airflow enters the first wind chamber a1 from the wind inlet 11 to exchange heat with the evaporator 20 under the action of the negative pressure, and then enters the second wind chamber a2 to be blown out from the wind outlet 12. Meanwhile, because the first air chamber a1 with negative pressure exists, air enters the heat dissipation air chamber b from the air return opening 13, dissipates heat to the electrical box 40, enters the second air chamber a2 from the communication opening 14 to exchange heat with the evaporator 20, and is mixed with the air entering from the air inlet 11.
In a preferred embodiment, as shown in fig. 2, the communication port 14 is also used for passing a thread, and a rubber ring 141 is attached to the communication port 14. More preferably, as shown in fig. 5, the rubber ring 141 is a corrugated wire-passing rubber ring. This line rubber circle is crossed to corrugated can be used for crossing the line, can ventilate again, does not receive the assembly error influence between two sheet metal components simultaneously, and the leakproofness is guaranteed to two cavitys of linking up that can be free.
Optionally, the open pore structure in this patent can be circular, square, can ventilate the structure for the like, also can be the filter screen formula structure.
Alternatively, the evaporator 20 is a V-shaped evaporator, and the evaporator structure of a straight plate evaporator also belongs to the field of the present invention.

In the technical scheme of the invention, a double-fan-blade structure that one motor 31 drives two fan blades and a volute 32 is adopted. As other alternative embodiments, structures such as a single blade and three blades are also applicable to the present invention. Optionally, the fan blade is a centrifugal fan blade.
It should be noted that the technical scheme of the invention is particularly suitable for the air duct machine,
The invention also provides an air conditioning unit which comprises the air supply equipment, and the air supply equipment can effectively utilize air flow to cool the electrical box, reduce temperature rise to ensure that electronic components can normally work, and ensure the normal operation of the electric control function of the air conditioning unit.
According to the technical scheme, the air supply equipment is divided into the three cavities, so that the electrical box of the air supply equipment can be arranged in the air supply equipment, the heat dissipation of the air supply equipment is not influenced, and the problem of electrical safety caused by condensation of the electrical box in the cold cavity is avoided. The air passing through the electrical box 40 can be pre-cooled in the first air cavity a1, so that condensation of the air in the second air cavity a2 can be prevented, and the energy efficiency can be improved.
