Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The first embodiment is as follows:

referring to fig. 1-4, the utility model provides a pair of heat radiation structure of on-vehicle ATR machine case, including box 1 and chamber door 5, the surface subsides of box 1 and/or chamber door 5 are equipped with radiating fin 2, and radiating fin 2's quantity has a slice at least moreover, and radiating fin 2 can direct welded fastening on the surface of box 1 and/or chamber door 5, also can be through screw demountable installation on the surface of box 1 and/or chamber door 5.

As shown in fig. 5 and 6, a channel 6 is provided in the heat dissipating fin 2, and the opening of the channel 6 is located at both ends of the heat dissipating fin 2 in the length direction; as shown in fig. 1-4, a mounting box 3 is fixedly mounted on a box body 1, one end of a channel 6 is communicated with the inside of the mounting box 3, a fan 4 with a filter screen 18 is mounted on the mounting box 3, the fan 4 sends outside air into the mounting box 3, then the air enters the channel 6 from one opening and finally leaves the channel 6 from the other opening, and the flow direction of the air is shown in fig. 2.

As shown in fig. 8, the back surface of the mounting box 3 is provided with an insertion hole 16, and one end of the heat dissipating fin 2 is inserted into the insertion hole 16 and communicated with the inside of the mounting box 3.

As shown in fig. 5, a temperature sensor 13 is mounted on the inner side surface of the box body 1 and/or the box door 5; the heat dissipation structure further includes a processor 14 for analyzing and processing the temperature data detected by the temperature sensor 13, and a controller 15 for controlling the operation of the fan 4 according to the processing information of the processor 14.

Of course, the heat dissipation structure may be provided with the battery 17, and as shown in fig. 5, the battery 17, the processor 14, and the controller 15 may be provided on the inner wall of the box body 1 and/or the door 5 together with the temperature sensor 13, or only the temperature sensor 13 may be provided on the inner wall of the box body 1 and/or the door 5.

When the temperature sensor 13 detects that the air temperature in the ATR case is lower than a set value A, the air temperature in the ATR case is low, at the moment, the fan 4 is not started, and only the ATR case is naturally cooled through the cooling fins 2;

when the temperature detected by the temperature sensor 13 is higher than the set value a, it indicates that the air temperature in the ATR chassis is high, at this time, the air temperature in the ATR chassis is reduced to a normal level only by the insufficient natural heat dissipation of the heat dissipation fins 2, the processor 14 sends a control instruction to the controller 15 according to the temperature information detected by the temperature sensor 13, the controller 15 controls the fan 4 to start, so that a high-speed air flow is formed in the channel 6, the heat on the heat dissipation fins 2 is taken away quickly, the heat exchange between the heat dissipation fins 2 and the air in the ATR chassis is accelerated, the air temperature in the ATR chassis is reduced to a reasonable value, and when the air temperature in the ATR chassis is reduced to below the set value a, the controller 15 controls the fan 4 to stop working.

The heat radiation structure heat dispersion of this embodiment is strong, can effectively guarantee ATR machine case normal work under high temperature environment, and the machine case still is the totally enclosed structural design moreover, and external dust can not get into quick-witted incasement, guarantees that ATR machine case can long-term stable work in various adverse circumstances, and the practicality is good.

Example two:

After the fan 4 is started for a period of time, the air temperature in the ATR case is still higher than a set value A and cannot be reduced to a normal temperature below the set value A, which indicates that the air temperature in the ATR case cannot be effectively reduced after the fan 4 is started, at the moment, water can be intermittently sprayed into the channel 6 through the water pipe 9, namely, the spray holes 7 are controlled to spray a small amount of water into the channel 6, the purpose of water spraying is to blow water drops through air flow generated in the channel 6 by the fan 4, so that liquid water is evaporated, the water is evaporated and absorbs heat, the cooling of the radiating fins 2 is accelerated, then, the heat exchange between the radiating fins 2 and the air in the ATR case is accelerated, and the air temperature in the ATR case is reduced.

Since the purpose of spraying water into the channel 6 from the spray holes 7 is to accelerate the cooling of the ATR cabinet by means of the evaporation of liquid water, the amount of water sprayed into the channel 6 from the through holes cannot be too large, otherwise the channel 6 may have water flowing out to cause water waste.

Preferably, the orifice 7 is located at an end of the channel 6 near the fan 4, as shown in fig. 2.

In order to timely and reliably provide water for the water pipe 9, the heat dissipation structure of the utility model also comprises a water tank 10, the water tank 10 can be fixedly connected with the box body 1 and/or the box door 5 (as shown in fig. 7) or can be separately and independently arranged; a water pump 12 is arranged in a water tank 10, the water pump 12 is connected with a water pipe 9 through a pipeline, the water pipe 9 preferably adopts a hose 11, the water pump 12 and a fan 4 can be controlled to be started and stopped by a controller 15, after the fan 4 is started for a period of time, the air temperature in the ATR case is still higher than a set value A and cannot be reduced to a normal temperature below the set value A, the controller 15 controls the water pump 12 to be started at intervals according to a control instruction of a processor 14, and therefore the spraying holes 7 can spray a proper amount of water into the channel 6.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
