Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a heat dissipation and rainproof structure and a parking air conditioner outdoor unit thereof. Background Art

[0002] Parking air conditioning is an air conditioning system designed for vehicles when they are parked, waiting or resting. It is powered by the on-board battery DC power supply and can adjust the temperature, humidity and air flow rate in the vehicle without starting the engine. As an increasingly popular device in modern vehicles, it can provide cooling or heating in the vehicle while the vehicle is stopped, thereby improving the environmental conditions in the cab.

[0003] At present, the appearance of the split parking air conditioner outdoor unit is basically the same as that of the household air conditioner outdoor unit. To ensure the heat dissipation of the drive module, as shown in the attached manual Figure 1 As shown, radiators are arranged on the left and right sides of the driving module 2 to absorb the temperature on the driving module 2. Generally, a heat dissipation vent 41 is opened on the sound insulation board 4, and the heat in the shell 1 is brought out through the heat exchange exhaust fan 3. In this way, when it rains, especially heavy rain, when using the air conditioner, the heat exchange exhaust fan 3 will introduce raindrops into the shell 1, and the raindrops can easily splash onto the wiring terminals of the driving module 2 through the heat dissipation vent 41, causing damage to the driving module 2. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a heat dissipation and rainproof structure and a parking air-conditioning outdoor unit thereof, so as to solve the problem that the heat exchange exhaust fan can easily introduce raindrops into the shell, and raindrops can easily splash onto the wiring terminals of the drive module through the heat dissipation vents, causing damage to the drive module.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: a heat dissipation and rainproof structure, comprising:

[0006] The water retaining unit installed at the heat dissipation vent can be covered, and a plurality of ventilating holes are arranged on the water retaining unit.

[0007] The technical principle of the utility model is that the water retaining unit can block the water droplets introduced into the shell by the heat exchange exhaust fan. At the same time, the ventilation holes can still transmit the heat dissipation airflow, which not only ensures heat dissipation, but also reduces the risk of the drive module being damaged by rain erosion.

[0008] Further, the water retaining unit comprises:

[0009] A water retaining box covers the heat dissipation vents, the vents are located on the water retaining box, and a connecting hole connecting the heat dissipation vents and the vents is provided on one side of the water retaining box close to the heat dissipation vents.

[0010] Through the above arrangement, the water retaining box can block the water droplets introduced into the shell by the heat exchange exhaust fan, and the connecting hole can cooperate with the ventilation hole so that the heat dissipation vent and the water retaining box remain connected, so that the heat dissipation remains unobstructed.

[0011] Furthermore, the ventilation hole penetrates through the side wall of the water retaining box, and the penetration direction of the ventilation hole is perpendicular to or intersects with the penetration direction of the heat dissipation vent.

[0012] Through the above arrangement, it is ensured that the ventilation holes are not directly opposite to the heat dissipation vents, so as to prevent water droplets flying into the ventilation holes from impacting the heat dissipation vents, thereby reducing the risk of the wiring terminals of the driver module being damaged by raindrops.

[0013] Furthermore, the ventilation holes are located on the side wall of the water retaining box which is perpendicular to the surface of the sound insulation board.

[0014] Through the above arrangement, the ventilation hole is not directly opposite to the sound insulation board, and the side of the water retaining box away from the sound insulation board can block raindrops, so that the amount of raindrops passing through the ventilation hole of the water retaining box is smaller.

[0015] Furthermore, a plurality of mounting ears are fixedly provided on the water retaining box and are detachably connected to a side of the sound insulation board away from the driving module.

[0016] Through the above-mentioned configuration, the configuration of the mounting ears can allow the water retaining box to be more stably installed on the sound insulation board. At the same time, since the water retaining box is located on the side of the sound insulation board away from the driver module, raindrops can be blocked by the water retaining box before passing through the heat dissipation vents, further reducing the probability of the driver module being eroded by raindrops.

[0017] Further, the water retaining unit also includes:

[0018] A water retaining wall plate is fixedly installed between the driving module and the heat dissipation vent of the sound insulation board, and a gap is formed between the water retaining wall plate and the sound insulation board;

[0019] A plurality of wind guide wall plates are fixedly and tiltedly mounted on the side walls of the water retaining wall plates, and the wind guide wall plates are tilted toward one side of the driving module.

[0020] Through the above-mentioned settings, the water retaining wall plate can further block the trace amount of raindrops that can enter the heat dissipation vents through the ventilation holes, thereby preventing trace amounts of water droplets from impacting the connection terminals of the drive module, further improving the rainproof properties of the heat dissipation and rainproof structure; the wind guide wall plate can guide the heat generated by the drive module, so that the heat on both sides of the drive module can be quickly discharged.

[0021] Furthermore, a mounting wall plate is fixedly provided on one side of the water retaining wall plate, and the mounting wall plate is detachably connected to the driving module or the sound insulation board.

[0022] Through the above arrangement, installing the wall panels can enable the water retaining wall panels to be more reliably connected to the driving module or the sound insulation panel, making the installation of the water retaining wall panels and the wind guide wall panels more stable.

[0023] Furthermore, the surface of the water retaining wall plate is parallel to the surface of the sound insulation board.

[0024] Through the above arrangement, the gap between the water retaining wall plate and the sound insulation board is more stable, and the heat dissipation airflow between the water retaining wall plate, the wind guide wall plate and the sound insulation board is also more stable during heat dissipation and ventilation.

[0025] Furthermore, the number of the wind guide wall plates is two, and the two wind guide wall plates are located at two vertical side walls opposite to the water retaining wall plate.

[0026] Through the above configuration, the air guide wall plate can guide the heat generated by the radiators on both sides of the driving module, so that the hot air can be quickly introduced from both sides of the driving module to the heat dissipation vents by the air guide wall plates, thereby improving the heat dissipation efficiency.

[0027] The utility model also intends to provide a parking air conditioner outdoor unit, which comprises a heat dissipation and rainproof structure.

[0028] Through the above settings, the heat dissipation and diversion effect at the drive module is enhanced, raindrops will not splash onto the wiring terminals of the drive module, the risk of damaging the drive module is eliminated, and the smoothness and service life of the entire parking air conditioner outdoor unit are improved.

DETAILED DESCRIPTION

[0036] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0037] Example 1

[0038] This embodiment is basically Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the utility model proposes a heat dissipation and rainproof structure, including a water retaining unit that can cover and be installed at the heat dissipation vent 41, the water retaining unit includes a water retaining box 50, a water retaining wall plate 601 and two wind guide wall plates 602, the water retaining box 50 covers the heat dissipation vent 41, and a connecting hole connecting the heat dissipation vent 41 and the ventilation hole 501 is provided on the side of the water retaining box 50 close to the heat dissipation vent 41, the connecting hole makes the side wall of the water retaining box 50 open, the ventilation hole 501 is penetrated on the lower side and the right side of the water retaining box 50, the penetration direction of the ventilation hole 501 is perpendicular to the penetration direction of the heat dissipation vent 41, and the ventilation hole 501 is away from the heat exchange exhaust fan 3.

[0039] At the same time, if Figure 2 and Figure 4 As shown, a mounting ear 502 detachably connected to the side of the sound insulation board 4 away from the driving module 2 is integrally formed on the upper and lower sides of the water retaining box 50, and the mounting ear 502 is connected to the sound insulation board 4 far away from the driving module 2 by bolts or screws.

[0040] like Figure 3 and 4 As shown, the water retaining wall plate 601 is in the shape of a thin plate, and the water retaining wall plate 601 is located between the heat dissipation vents 41 of the driving module 2 and the sound insulation board 4. A mounting wall plate 603 is integrally formed on the lower side of the water retaining wall plate 601, and the mounting wall plate 603 is detachably connected to the end of the driving module 2 by bolts or screws. A gap is formed between the water retaining wall plate 601 and the sound insulation board 4 or the driving module 2, and the surface of the water retaining wall plate 601 is parallel to the surface of the sound insulation board 4.

[0041] At the same time, if Figure 3 and Figure 4 As shown, the wind guide wall plate 602 is tilted and integrally formed on the left and right side walls of the water retaining wall plate 601 , and the wind guide wall plate 602 is tilted toward the driving module 2 .

[0042] When the heat dissipation and rainproof structure in this embodiment is in use, the side of the water retaining box 50 away from the heat dissipation vent 41 can block raindrops. At the same time, the ventilation holes 501 located on the side wall of the water retaining box 50 can still transfer the heat of the airflow. During the heat dissipation process, the airflow is discharged from away from the heat exchange exhaust fan 3, preventing water droplets from directly entering from the side wall of the water retaining box 50 close to the heat exchange exhaust fan 3, thereby further improving the water isolation effect.

[0043] At the same time, the water retaining wall plate 601 and the two wind guide wall plates 602 can separate the side of the driving module 2 close to the heat dissipation vent 41, thereby further achieving a water retaining effect; at the same time, the wind guide wall plate 602 can guide the heat generated by the radiators on both sides of the driving module 2, so that the hot air can be quickly introduced from both sides of the driving module 2 by the wind guide wall plates 602 to the heat dissipation vent 41, and then discharged through the ventilation holes 501 of the water retaining box 50, so that the heat on both sides of the driving module 2 can be quickly discharged.

[0044] The entire heat dissipation and rainproof structure not only ensures the ventilation and heat dissipation effect but also ensures that raindrops do not splash onto the wiring terminals of the drive module 2 , thereby eliminating the risk of damaging the drive module 2 .

[0045] Example 2

[0046] The difference between Example 2 and Example 1 is basically as shown in the attached Figure 5 and Figure 6 As shown, a parking air conditioner outdoor unit is proposed, including a heat dissipation and rainproof structure in Example 1.

[0047] When a parking air-conditioning outdoor unit in the present embodiment is in use, the water retaining box 50 is stably installed on the heat dissipation vent 41 of the sound insulation board 4 through the mounting ear 502, and the water retaining wall plate 601 and the wind guide wall plate 602 are stably installed on the end of the driving module 2 through the mounting wall plate 603. While being able to block water from the heat dissipation vent 41, the heat dissipation and diversion effect at the driving module 2 is enhanced, and raindrops will not splash onto the wiring terminals of the driving module 2, eliminating the risk of damaging the driving module 2, thereby improving the smoothness and service life of the entire parking air-conditioning outdoor unit during use.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
