Application Overview

With the development of engineering machinery technology, air conditioning systems have been widely used in some engineering machinery such as loaders, which can adjust the temperature in the cab and provide drivers with a more comfortable operating environment. However, most of the current air-conditioning systems in construction machinery are copied from automobile air-conditioning systems. Since the usage environments of construction machinery and automobiles are completely different, it is difficult for existing air-conditioning systems to adapt to the construction conditions of construction machinery. Taking a loader as an example, the condenser of the air-conditioning system is usually installed on the frame. Since the construction environment of the loader is relatively complex, and splashes of dust and road mud are common, the condenser of the existing loader air-conditioning system is not resistant to dirt. The plugging ability is relatively poor and the design margin is insufficient, which can easily cause problems such as dust accumulation and muddy water accumulation blocking the condenser core 22. Although some related technologies provide a condenser protection box, which can play a certain protective role, the ventilation structure design still has flaws. The ventilation and heat dissipation efficiency of the condenser after assembly is poor, and the condenser is still damaged during long-term use. Dust, mud and water blockage affect the normal operation of the air conditioning system.

Some examples of the construction machinery condenser device and construction machinery in the technical solution of the present invention are provided below.

In one embodiment of the first aspect of the present invention, an engineering machinery condenser device 100 is provided. As shown in FIGS. 1 and 2 , it includes a box 1 and a condenser assembly 2 . The box 1 serves as the protective structure and installation base of the condenser assembly 2. The condenser assembly 2 is arranged in the box 1 and can be installed and connected to the frame 511 of the construction machine 500 through the box 1. The bottom plate of the box 1 is a first mesh plate 11, and one side plate of the box 1 is a second mesh plate 12; the first mesh plate 11 is provided with a plurality of air inlet meshes 111, and the second mesh plate A plurality of air outlet meshes 121 are provided on the box 12, and the air inlet and outlet through the air inlet mesh 111 and the air outlet mesh 121 form an air passage in the internal space of the box 1. The condenser assembly 2 is arranged in the box 1, and the air inlet side of the condenser assembly 2 is arranged corresponding to the air inlet mesh 111, and the air outlet side of the condenser assembly 2 is arranged corresponding to the air outlet mesh 121, so that the air inlet The airflow entering the box 1 through the mesh 111 can dissipate heat to the condenser assembly 2, and then flows out through the air outlet mesh 121.

Wherein, the condenser assembly 2 can be arranged in a vertical direction, for example, in the state shown in FIG. 1 , the condenser assembly 2 is perpendicular to the first mesh plate 11 and parallel to the second mesh plate 12 ; of course, the condenser assembly 2 It can also be set at a certain tilt angle to the vertical direction, which can be set according to specific assembly needs.

It can be understood that in the prior art, the air inlet and air outlet of the condenser protection box are usually arranged on the side panel of the box 1 in the same direction. When used in construction machinery such as loaders, due to the harsh construction environment, the tires will rotate. Splashing muddy water and flying dust will occur. The existing air inlet and outlet structure will cause serious dust absorption. Moreover, the muddy water splashed on site can easily enter the box and accumulate in the box. The above situation can easily cause the condenser to become clogged, leading to condensation. Air conditioner failure affects the normal operation of the air conditioning system.

The construction machinery condenser device 100 in this embodiment has improved and optimized the overall structure and the air inlet and outlet methods so that the air inlet mesh 111 of the box 1 is located on the bottom plate of the box 1, which can not only effectively reduce muddy water and dust into the box 1, and some of the muddy water and dust entering the box 1 can be discharged out of the box 1 through the air inlet mesh 111 when it falls due to gravity, thereby reducing the accumulation of dust and muddy water in the box 1, which can effectively reduce The possibility of blockage of the condenser assembly 2; at the same time, when assembled in construction machinery, the air inlet mesh 111 of the box 1 will not be blocked by the frame or other parts of the body, which can effectively improve the ventilation and heat dissipation efficiency, which is beneficial to Improve the performance and operation of air conditioning systems.

It should be noted that the construction machinery 500 described in the embodiment of the present invention includes but is not limited to a loader.

In a further embodiment of the present invention, as shown in Figures 1 and 2, since the condenser assembly 2 is vertically disposed in the box 1, some areas of the first mesh plate 11 are located on the condenser assembly. The air inlet side of the condenser assembly 2 is located on the air inlet side of the condenser assembly 2 . Correspondingly, the air inlet mesh 111 is arranged on the first mesh plate 11 at a position away from the second mesh plate 12 so that the air inlet mesh 111 is located on the air inlet side of the condenser assembly 2 to ensure that the condenser Component 2 is located on the air passage. The airflow entering the box 1 through the air inlet mesh 111 can cover the condenser component 2. Heat is exchanged during the contact between the airflow and the condenser component 2, thereby achieving air-cooling and heat dissipation of the condenser component 2. Effect.

Among them, the first mesh plate 11 forms a downward air inlet structure through a plurality of air inlet meshes 111. The overall air inlet area of the first mesh plate 11 is greater than 1.2 times the air inlet demand of the condenser assembly 2, so as to Meet the heat dissipation needs of condenser assembly 2. Specifically, the overall air inlet area can be determined by setting the number of air inlet meshes 111 . Specifically, the air inlet mesh 111 may be a circular hole with a diameter of 30 mm. The air inlet demand of the condenser assembly 2 can be calculated based on the air inlet demand area, and the air inlet demand area is equal to the circular area covered by the diameter of the fan blade of the condenser assembly 2, so it can be calculated by the diameter size of the fan blade. .

It can be understood that the air inlet demand of the condenser is usually related to the size, structure, etc. If the actual air inlet area is too small, it will be difficult to meet the normal air inlet demand of the condenser. In this embodiment, the overall air inlet area of the air inlet mesh 111 is set according to the air inlet demand of the condenser assembly 2, and a margin of more than 20% is set, which can effectively meet the needs of the condenser assembly 2 during normal operation. air intake demand.

Further, as shown in Figures 2 and 3, on the first mesh plate 11, the plurality of air inlet meshes 111 are divided into a plurality of different mesh areas, such as the first mesh area shown in Figure 3 1111 and the second mesh area 1112, and there is a spacing between different mesh areas. When other accessory components are installed in the box 1, different mesh areas can be passed and divided, and different mesh areas can be used. The spacing between them avoids the supporting structures of accessory components (such as mounting brackets) or other structures that do not require wind and heat dissipation. On the one hand, it can prevent part of the air inlet mesh 111 from being blocked by the above structures, and on the other hand, it can meet the requirements of the installation of the above structures. Strength requirements. The shape and number of the mesh areas can be set according to the specific layout in the box 1 .

In a further embodiment of the present invention, as shown in Figures 2 and 3, a first fixing plate 13 is provided on the inner wall of the box 1 for fixing the condenser assembly 2. The first fixed plate 13 is located between the air inlet mesh 111 and the second mesh plate 12, and extends a certain distance to the inside of the box 1. The condenser assembly 2 and the first fixed plate 13 are detachably connected to prevent condensation. The condenser assembly 2 is connected and fixed, and the condenser assembly 2 is arranged opposite to the air outlet mesh 121 of the second mesh plate 12 . Among them, the air inlet meshes 111 on the first mesh plate 11 are located on the other side of the first fixed plate 13 relative to the second mesh plate 12, so that the air inlet meshes 111 are located at the inlet of the condenser assembly 2. wind side.

Specifically, the first fixing plate 13 can be provided with corresponding connection holes (such as bolt holes); the first fixing plate 13 can be welded and fixed to the inner wall of the box 1, or can be connected by bolts or riveting using a bent plate structure. Connect with the inner wall surface of box 1 in other ways. In addition, the first fixing plates 13 can be provided on the four inner wall surfaces of the upper, lower, left and right sides of the box 1 , as shown in the example in Figure 3 , where the inner wall surface of the lower part of the box 1 is the inner wall surface of the first mesh plate 11 ; Of course, the first fixing plate 13 can also be provided on only two or three inner wall surfaces. Specifically, the first fixing plate 13 can be provided according to the connection structure of the condenser assembly 2.

Preferably, as shown in the example in Figure 3, the first fixing plate 13 can be disposed relatively close to the second mesh plate 12 in the box 1, which can expand the space on the air inlet side of the condenser assembly 2. Correspondingly, It is also possible to increase the area of the first mesh plate 11 corresponding to the air inlet side, which is conducive to arranging more air inlet meshes 111 to enhance the ventilation effect.

Furthermore, as shown in FIG. 3 , a second fixing plate 14 is also provided on the inner wall of the box 1 for fixing the second mesh plate 12 . The second fixing plate 14 is located between the first fixing plate 13 and the outer edge of the box 1. Similar to the first fixing plate 13, the second fixing plate 14 extends a distance to the inside of the box 1. The second mesh plate 12 is detachably connected to the second fixing plate 14 to connect and fix the second mesh plate 12 so that the air outlet mesh 121 of the second mesh plate 12 is opposite to the condenser assembly 2 . Among them, the second fixed plate 14 can be provided with corresponding connection holes (such as bolt holes). The second fixed plate 14 can be welded and fixed to the inner wall surface of the box 1, or can be connected by bolts or riveting using a bent plate structure. Connected to the inner wall of box 1. Among them, the outer edge of the box 1 on the side of the second fixing plate 14 extends outward for a certain distance relative to the second mesh plate 12, so that one side of the second mesh plate 12 realizes a concave design, and the box 1 The outer edges of the side walls (including the outer edges of the upper, lower, left, and right side walls) located around the second mesh plate 12 can surround and shield the second mesh plate 12 to a certain extent, and can prevent muddy water splashed during the construction process. A certain protective effect.

It can be understood that, as shown in the example in FIG. 1 , when the construction machinery condenser device 100 is applied to construction machinery such as a loader, it is usually installed on the side of the frame and between the front and rear tires. During the construction process of engineering machinery, the rotation of tires is the main cause of muddy water splashing, and when muddy water splashes, it mainly moves in the front and rear directions. By arranging the side of the box with the second mesh plate 12 and designing it as a concave structure, it can The outer edge of the outward side wall is used to effectively protect muddy water.

In a further embodiment of the present invention, as shown in Figures 1 to 3, a mounting structure 151 is provided on the other side of the box 1 opposite to the second mesh plate 12. When applied to construction machinery such as loaders, , the installation structure 151 can be connected and fixed with the frame 511 of the construction machine 500 to realize the assembly of the condenser device 100 of the construction machine. The mounting structure 151 may specifically adopt a lug plate structure as shown in FIG. 3 , and corresponding mounting holes (such as bolt holes) are provided on the lug plate structure to facilitate connection and fixation. The number and specific positions of the mounting structures 151 can be set according to the specific structure of the vehicle frame 511 .

Further, the front and/or rear part of the box 1 is provided with a baffle 152, such as the front baffle shown in FIG. 3, which extends downward for a distance to protect the first mesh plate 11. It has a shielding and protective effect, which can effectively reduce the possibility of splashing muddy water entering the box 1 through the air inlet mesh 111 of the first mesh plate 11 . Preferably, baffles 152 can be provided at the front and rear of the box 1 at the same time, so that the front and rear sides of the first mesh plate 11 are shielded and protected at the same time. Specifically, the baffle 152 can be an integrated structure with the side plate of the box 1 and extend downward through the side plate to function as a baffle. Of course, the baffle 152 and the side plate of the box 1 can also be a separate structure. It is connected and fixed with the side plate by welding or bolting.

Further, the front side wall or the rear side wall of the box 1 is provided with an access opening 161, and an access cover 162 is provided at the access opening 161. The access cover 162 can be flipped or slid relative to the access opening 161 to open. Or close the access port 161. When it is necessary to perform maintenance operations on the condenser assembly 2 or other ancillary components in the box 1, it is only necessary to open the inspection cover 162 and the maintenance operation is required without removing the box 1, which is convenient and fast. The specific position of the inspection opening 161 can be set according to the specific position of the box 1 on the frame 511 to provide sufficient space for inspection operations. For example, in the example in Figure 2, when the box 1 is connected to the side of the frame 511 and is located between the front and rear tires, if the box 1 as a whole is relatively close to the rear tires, an access hatch can be provided on the front side wall of the box 1 161; If the entire box 1 is relatively close to the front tire, an access port 161 can be provided on the rear side wall of the box 1.

In a further embodiment of the present invention, as shown in FIGS. 2 and 4 , the condenser assembly 2 includes a condenser fixed support 21 , a condenser core 22 and a condenser fan 23 . The condenser fixed support 21 is detachably connected to the box 1, and the condenser core 22 is connected to the side of the condenser fixed support 21 facing the second mesh plate 12; the condenser fixed support 21 is provided with an air inlet. 213. The condenser fan 23 is arranged on the condenser fixed support 21 at a position corresponding to the air inlet 213, so as to accelerate the air flow movement through the condenser fan 23, so that the air flow entering the box 1 through the air inlet mesh 111 is passed through the air inlet 213. The position of the condenser core 22 is quickly sucked in, which is beneficial to accelerating heat dissipation.

Further, as shown in FIGS. 2 and 4 , the condenser fixed support 21 specifically includes a support frame 211 and an air guide cover 212 . The support frame 211 is provided correspondingly to the inner wall of the box 1 for connection with the box 1; specifically, the support frame 211 is provided with corresponding connection holes (such as bolt holes). When the inner wall of the box 1 When the first fixing plate 13 is provided on the support frame 211, the support frame 211 can be connected and fixed with the first fixing plate 13. The air guide 212 is connected to the support frame 211, and the air guide 212 protrudes in a direction away from the condenser core 22, that is, protrudes toward the air inlet side of the condenser assembly 2; the air guide 212 has an inlet opening. The air inlet 213 is provided with a filter 214 at the air inlet 213 to further filter the inlet airflow and prevent large particles of dust from entering and causing damage to the condenser fan 23 and the condenser core 22 . The condenser fan 23 is disposed in the inner space of the air guide 212 and is disposed corresponding to the air inlet 213, so that the airflow on the air inlet side passes through the filter 214 of the air inlet 213 and is sent to the condenser through the suction of the condenser fan 23. The position of core 22. Among them, in the direction from the air inlet 213 to the condenser core 22, the size of the air guide 212 gradually expands and covers the condenser core 22, so that the air guide 212 forms a trumpet-like structure to achieve control of the air flow. The guiding function makes the air flow blow to different parts of the condenser core 22 relatively evenly, which is beneficial to improving the uniformity of heat dissipation of the condenser core 22 and preventing local area overheating.

It can be understood that since the shape of the condenser fan 23 is not consistent with the shape of the condenser core 22, and usually the area of the condenser fan 23 is smaller than the area of the condenser core 22, if only the condenser fan 23 is relied on for air supply. , it is easy to cause a large air volume in the area directly facing the condenser fan 23 on the condenser core 22, and a small air volume in the area far away from the condenser fan 23, which is prone to uneven heat dissipation, local overheating and other phenomena.

In this embodiment, the air guide 212 is provided with a gradually enlarged size to guide the air flow, so that the air flow can be sent to different areas on the condenser core 22 relatively uniformly, and the heat dissipation area and effect are better.

Further, the wave pitch of the condenser core 22 is not less than the first wave pitch threshold. For example, the first wave pitch threshold can be set to 4mm. That is, using the condenser core 22 with a relatively large wave pitch can effectively reduce the adhesion of fine dust. on the condenser core 22, thereby further reducing the possibility that the condenser core 22 is clogged by dust. The heat dissipation capacity of the condenser core 22 is set to 1.3 times the required heat dissipation. Even if a 30% performance degradation occurs, the condenser core 22 can still ensure the normal heat dissipation demand to meet the cooling needs in the cab.

Furthermore, the condenser fan 23 specifically adopts a brushless fan with adjustable rotation speed, which can adjust the rotation speed according to the specific heat dissipation requirements, which is beneficial to energy saving and consumption reduction; by adjusting the rotation speed, the condenser fan 23 can realize a large air volume air supply operation. It is helpful to further enhance the heat dissipation effect. Among them, as shown in FIG. 5 , the condenser fan 23 is provided with a reverse rotation protection module 231 , a stall protection module 232 and a reverse connection protection module 233 to provide corresponding protection to the condenser fan 23 . Specifically, the reversal protection module 231 plays a protective role when the condenser fan 23 reverses; the locked-rotor protection module 232 plays a protective role when the condenser fan 23 is clogged and cannot rotate normally, preventing the condenser fan 23 from continuing to output rotation. The reverse connection protection module 233 plays a protective role when a reverse connection occurs when the condenser fan 23 is connected to prevent damage caused by starting the condenser fan 23 in a reverse connection state.

In another implementation, the condenser fan 23 can also have a forward and reverse function. According to the needs of use, the condenser fan 23 can be controlled to reverse, and the reverse air flow movement can be used to achieve dust removal, which is beneficial to further reducing the condenser core. 22 Possibility of being clogged with dust.

The condenser fixed support 21 specifically includes a support frame 211 and an air guide cover 212 . The support frame 211 is provided correspondingly to the first fixing plate 13 . The support frame 211 is provided with corresponding connection holes (for example, bolt holes). The support frame 211 is connected and fixed with the first fixing plate 13 . The air guide 212 is connected to the support frame 211, and the air guide 212 protrudes in a direction away from the condenser core 22, that is, protrudes toward the air inlet side of the condenser assembly 2; the air guide 212 has an inlet opening. The air inlet 213 is provided with a filter 214 at the air inlet 213 . In the direction from the air inlet 213 to the condenser core 22, the size of the air guide 212 gradually expands and covers the condenser core 22, so that the air guide 212 forms a trumpet-like structure to guide the air flow. The action causes the air flow to blow to different parts of the condenser core 22 relatively evenly. The condenser fan 23 is disposed in the inner space of the air guide 212 and is disposed corresponding to the air inlet 213, so that the airflow on the air inlet side passes through the filter 214 of the air inlet 213 and is sent to the condenser through the suction of the condenser fan 23.

Correspondingly, the overall air inlet area of the first mesh plate 11 is greater than 1.2 times the air inlet demand of the condenser assembly 2 to meet the heat dissipation demand of the condenser assembly 2 .

The construction machinery condenser device 100 in this embodiment has improved and optimized the overall structure and the air inlet and outlet methods so that the air inlet mesh 111 of the box 1 is located on the bottom plate of the box 1, which can not only effectively reduce muddy water and dust into the box 1, and some of the muddy water and dust entering the box 1 can be discharged out of the box 1 through the air inlet mesh 111 when it falls due to gravity, thereby reducing the accumulation of dust and muddy water in the box 1, which can effectively reduce The possibility of blockage of the condenser assembly 2; at the same time, when assembled in construction machinery, the air inlet mesh 111 of the box 1 will not be blocked by the frame or other parts of the body, which can effectively improve the ventilation and heat dissipation efficiency, which is beneficial to Improve the performance and operation of air conditioning systems.

In addition, by using the condenser core 22 with a large wave pitch and the condenser fan 23 with a large air volume, the possibility of the condenser core 22 being blocked can be further reduced. At the same time, the use of an air guide 212 with a trumpet-like structure is beneficial to The inlet airflow is evenly guided to different parts of the condenser core 22, and the heat dissipation is more uniform, which is beneficial to preventing local overheating.
