Description
Technical Field
The invention relates to a protective device for a condenser of a vehicle, in particular to a protective cover for the condenser.
Background
An air conditioner cooling system is generally installed on an existing truck, the air conditioner cooling system comprises a cooler which is arranged at a position with a good ventilation effect, a protective cover is arranged on the windward side of the outside of the cooler to protect the cooler, foreign matters such as flying sand and stone are prevented from striking the condenser in the windward side of the cooler in the running process of the vehicle, the cooling fins of the condenser are damaged or the cooling pipes are damaged, and then the cooling effect of the condenser is reduced.
Under the conditions of high speed and large load capacity of the truck, the heat generated by the engine is more, and the heat dissipation requirement on the condenser is higher at the moment, otherwise, the condition of high-temperature alarm is easy to generate, and the normal operation of the engine is influenced. The condenser mainly generates airflow flowing through the condenser in the running process of the vehicle, so that the airflow brings heat of the condenser away to realize heat dissipation. The protective cover of the condenser needs to block foreign matters from striking the condenser, but the blocking effect on the air flow is reduced, so that more through holes are formed in the protective cover, and the air flow is conveniently blown to the condenser. When the foreign matter drifts in the air, the vehicle can generate larger relative speed with the foreign matter when the running speed of the vehicle is higher, and even the foreign matter with smaller volume and mass can generate larger impact force. Therefore, the aperture of the through hole on the protective cover is generally smaller, and after the aperture of the through hole is smaller, the aperture ratio of the protective cover is reduced so as to ensure the strength of the whole protective cover, thereby reducing the flow section of the air flow.
The inventor finds that when the truck runs at a low speed under the condition of large load capacity, the heat dissipation effect of the condenser is not ideal, and a high-temperature alarm condition is generated occasionally. Through analysis, the original protective cover of the condenser has a great influence on the heat dissipation effect of the condenser.
Disclosure of Invention
The invention aims to provide a protective cover for a condenser, which is used for solving the problem that the protective cover of the condenser of a truck has great influence on heat dissipation of the condenser in the prior art.
The basic scheme of the invention is as follows: the protective cover for the condenser comprises a cover body, wherein the cover body comprises an windward plate, a plurality of through holes are formed in the windward plate, an adjusting plate is arranged on the windward side of the windward plate and is in sliding fit with the windward plate, a plurality of adjusting holes are formed in the adjusting plate and are opposite to the through holes one by one, the cross section of each adjusting hole is identical to the cross section of each through hole, a wedge block is fixedly arranged on the cover body, and the adjusting plate is in sliding fit with the wedge surface of the wedge block.
Compared with the prior art, the scheme has the advantages that: through setting up regulating plate and regulation hole, through the relative slip of regulating plate and windward plate, the dislocation takes place for through-hole and the regulation hole that is in the coincidence state to reduce the aperture effective cross-sectional area of through-hole and regulation hole, and then adjust the aperture ratio of whole protection casing. By arranging the wedge blocks, the pressure of the air flow acting on the adjusting plate is utilized to push the adjusting plate to slide relatively with the wedge blocks, so that the relative sliding between the adjusting plate and the windward plate is completed.
The inventor finds that when the load capacity of the truck is small, the running speed is high, and power components such as an engine and the like are in a high-load working state, so that the heating value is large, and the heat dissipation condition of a condenser is good at the moment, so that the vehicle keeps a normal running state; however, when the carrying capacity of the truck is large, power components such as an engine and the like are in a high-load working state, and the heating value is large, but the situation that the heat dissipation condition of a condenser is not good is frequently found, and a high-temperature alarm prompt can be generated occasionally; it was found through research analysis by the inventors that this phenomenon can be improved by changing the opening ratio of the shield of the condenser.
The aperture ratio of the through hole on the windward plate of the cover body of the protective cover is set according to the heat dissipation requirement when the vehicle runs at a low speed, and the adjusting plate with the same adjusting hole as the through hole is arranged at the same time, so that the adjusting hole is overlapped with the through hole in a normal state, the air flow is large, and the heat dissipation is more; when the automobile runs at a high speed, the adjusting plate is driven to slide by utilizing high-speed wind pressure, so that the cross section area of the effective hole is reduced after the through hole and the adjusting hole are dislocated, and therefore, foreign matters with smaller volume are reduced to pass through the through hole and collide with the condenser, and the protective cover plays a role in protecting the condenser. Compared with the protective cover in the prior art, the influence of the protective cover on the heat dissipation effect of the condenser is reduced.
Further, the wedge block is positioned between the windward plate and the adjusting plate, a plurality of connecting holes which are coincident with the through holes are formed in the wedge block, and the wedge block is detachably connected with the windward plate. The wedge blocks are arranged to drive the adjusting plate to slide relatively with the windward plate, so that the adjusting plate and the windward plate can have a space for moving the adjusting plate, the wedge blocks are arranged between the windward plate and the adjusting plate, the space between the adjusting plate and the windward plate is fully utilized, the occupation of extra space is reduced, and the influence on the installation space inside the existing vehicle caused by adjustment can be reduced.
Further, the wedge surface of the wedge block vertically intersects with the plate surface of the windward plate, and the adjusting plate is in sliding fit with the wedge block along the transverse direction. The adjusting plate slides relatively between the wedge block and the transverse direction, so that the sliding phenomenon of the adjusting plate caused by jolt of a vehicle in the running process of the vehicle is avoided.
Further, the cross section of the adjusting block is trapezoid, and the windward side of the adjusting block is parallel to the windward side of the windward plate. The cross section of the adjusting plate is arranged into a trapezoid, and after the adjusting plate is combined with the wedge block, the wedge block and the adjusting plate form a cuboid together, so that the appearance of the whole protective cover is more regular.
Further, the regulating block is connected with an elastic reset piece along the sliding direction. Through setting up the elastic reset piece, make things convenient for the regulating plate to realize automatic re-setting.
Further, the through holes are distributed in a rectangular array on the windward plate, and the through holes are round holes. The through holes are distributed in a rectangular array mode, so that the position positioning and processing of the through holes on the windward plate are facilitated.

An embodiment is substantially as shown in figures 1, 2 and 3 of the accompanying drawings: the protective cover for the condenser comprises a cover body 2, wherein the cover body 2 comprises an windward plate 21, a plurality of round through holes 211 are formed in the windward plate 21, and the through holes 211 are distributed on the windward plate 21 in a rectangular array. The windward plate 21 is on the leeward side near the condenser 1, and on the windward side far from the condenser 1. The windward side of the windward plate 21 is provided with a wedge block 22, the cross section of the wedge block 22 is in a right triangle shape, the longer right-angle side of the cross section of the wedge block 22 is parallel to the plate surface of the windward plate 21, and the wedge surface of the wedge block 22 is intersected with the windward plate 21 along the vertical direction of the windward plate 21; the wedge block 22 is connected with the windward plate 21 through screws, and a plurality of connecting holes 221 which are opposite to the through holes 211 one by one are arranged on the wedge block 22. The windward side of the wedge block 22 is provided with an adjusting plate 23, the adjusting plate 23 is in transverse sliding connection with the wedge block 22, the wedge block 22 is provided with a chute, and the adjusting plate 23 is provided with a bump in sliding fit with the chute. The cross section of the adjusting plate 23 is trapezoid, and the windward side of the adjusting plate 23 is parallel to the windward side of the windward plate 21. The adjusting plate 23 is provided with a plurality of circular adjusting holes 231, the adjusting holes 231 are opposite to the through holes 211 and the connecting holes 221 one by one, and the aperture of the adjusting holes 231 is the same as the aperture of the through holes 211 and the connecting holes 221.

The specific implementation process is as follows: the through holes 211 on the windward plate 21 are arranged according to the aperture size which meets the heat dissipation requirement of the condenser 1 when the vehicle runs at a slower speed. When the vehicle runs at a slow speed, as shown in fig. 1, the adjusting holes 231 on the adjusting plate 23, the connecting holes 221 of the wedge blocks 22 and the through holes 211 on the windward plate 21 are in a superposition state, so that the actual aperture ratio of the cover body 2 is larger, the blocking effect of the cover body 2 on the air flow is smaller, and enough air flow is blown to the condenser 1 when the vehicle runs at a slow speed, so that the condenser 1 dissipates heat well. When the vehicle runs at a faster speed, as shown in fig. 2, the adjusting plate 23 receives a larger wind pressure generated by the air flow blown from the head-on side, and the wind pressure generates a larger thrust force on the adjusting plate 23 along the wedge surface parallel to the wedge 22, so that the adjusting plate 23 compresses the spiral spring 3 to slide, and further the adjusting hole 231 and the connecting hole 221 are dislocated, so that the effective hole section of the through hole 211 on the windward plate 21 is reduced, and therefore, when the vehicle runs at a faster speed, the foreign matters scattered in the air pass through the through hole 211 to collide with the condenser 1, and the windward plate 21 plays a good role in protecting the condenser 1.
