Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

As shown in fig. 1, a vehicle-road cooperation apparatus 1 according to an embodiment of the present application includes: a housing 10, a motherboard 20, and a heatpipe heat sink 30.

Specifically, the inside of the casing 10 defines a closed cavity 10a, and a liquid heat-conducting medium is disposed in the closed cavity 10 a. That is, the inside of the case 10 is constructed in a closed structure to isolate the inside of the cavity 10a from the outside. Therefore, impurities such as water or dust in the external environment can be prevented from entering the cavity 10a, and the waterproof, dustproof and anticorrosion effects are achieved. Also, the heat transfer medium in a liquid state can be prevented from leaking from the inside of the cavity 10a to the outside of the housing 10.

For example, the heat conducting medium may be a liquid having an insulating property and good chemical inertness, and specifically, the heat conducting medium may be an electron fluorinated liquid, a silicone oil, a mineral oil (e.g., white oil), or another liquid. Preferably, an electronic fluorination liquid having extremely low surface tension and kinematic viscosity and having a non-combustible property may be used as the heat transfer medium.

Illustratively, the heat transfer medium may be supplemented into the cavity 10a or discharged as needed. Specifically, the top wall of the housing 10 is provided with an input hole and the bottom wall is provided with an output hole, the input hole and the output hole are both communicated with the inside and the outside of the cavity 10a, and the heat transfer medium can be supplemented into the cavity 10a through the input hole or discharged from the cavity 10a through the output hole. Therefore, on the one hand, the liquid level of the heat-conducting medium can be adjusted according to the position of the component 21 on the main board 20, so that the component can be immersed in the heat-conducting medium. On the other hand, the high-temperature heat-conducting medium after heat exchange can be discharged and injected into the low-temperature heat-conducting medium. The discharged high-temperature heat-conducting medium can be input into the cavity 10a for recycling after being cooled.

The main board 20 is disposed in the enclosed cavity 10a, the main board 20 is mounted with the component 21, and the component 21 is immersed in the heat-conducting medium. For example, the liquid level of the heat-conducting medium may be higher than that of the motherboard 20, so that the components 21 on the motherboard 20 are immersed in the heat-conducting medium. As a support for the components 21, the main Board 20 may be a Printed Circuit Board (PCB).

Illustratively, as shown in fig. 2, the component 21 may be multiple and include a first component 211 and a second component 212. The first component 211 may be other components with relatively large heat productivity, such as a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), and the like, and the Central Processing Unit and the Graphics Processing Unit may be respectively provided with one or more components; the second component 212 may be another component with a small amount of heat generation, such as a memory.

The heat pipe radiator 30 includes a condensation portion 32 and an evaporation portion 31, the evaporation portion 31 is attached to the component 21, and the condensation portion 32 is attached to the inner wall of the housing 10.

For example, the heat pipe radiator 30 may adopt a split type heat pipe, and the heat pipe radiator 30 further includes a refrigerant that flows back and forth between the condensing portion 32 and the evaporating portion 31. Specifically, the refrigerant absorbs heat in the evaporation portion 31 and evaporates, and is converted from a liquid state to a gas state, so as to absorb heat emitted by the component 21 attached to the evaporation portion 31, thereby cooling the component 21 in time. The liquid refrigerant enters the condensing portion 32 and then exchanges heat with the outside through the wall body attached to the condensing portion 32, so that the heat emitted by the component 21 is finally conducted to the outside, and the refrigerant is converted from a gas state to a liquid state and then enters the evaporating portion 31 to absorb heat and evaporate, so that the refrigerant circulates. Accordingly, heat generated during operation of the component 21 can be discharged to the outside by the circulation of the refrigerant between the condensation portion 32 and the evaporation portion 31.

In a specific example, as shown in fig. 2, the heat pipe radiator 30 may include a plurality of evaporation portions 31, and the plurality of evaporation portions 31 are provided in one-to-one correspondence with the plurality of first components 211. The evaporation portion 31 may be attached to the first component 211 with a large heat value, so as to directly transmit the heat generated by the first component 211 during the operation process to the condensation portion 32, and then transmit the heat to the outside through the wall body attached to the condensation portion 32. The second component 212 is immersed in the heat-conducting medium, heat generated by the second component 212 in the working process can be directly conducted to the liquid heat-conducting medium, the density of the heat-conducting medium after heat absorption and temperature rise changes, natural convection occurs inside the heat-conducting medium to realize heat transfer, and the transferred heat is conducted to the outside through a wall body in contact with the liquid heat-conducting medium. Therefore, by providing the evaporation portions 31 corresponding to the number of the first components 211 according to the difference in the amount of heat generated by each component 21, it is possible to ensure a good heat dissipation effect for the first components 211 having a large amount of heat generation, and to reduce the number of the evaporation portions 31, so that the number of the evaporation portions 31 is more reasonable, thereby reducing the equipment cost of the heat pipe radiator 30.

It should be noted that, in the related art, the vehicle-road cooperative device usually adopts an air-cooling heat dissipation manner, that is, a material silicone grease (or a heat conducting gasket) is arranged on a thermal interface of a heating chip of the main board, and a fin-type air-cooling heat sink is arranged, so that external cold air is introduced by a fan, and forced convection heat exchange is performed with other components such as heat dissipation fins and board cards, thereby realizing heat transfer. The heat dissipation mode cannot avoid many defects caused by outdoor environment factors, so that the reliability of the vehicle-road cooperative equipment is low, and the subsequent operation and maintenance cost is high.

According to vehicle road cooperative equipment 1 of this application embodiment, through injecing closed cavity 10a and be equipped with liquid heat-conducting medium in closed cavity 10a in casing 10, the component 21 submergence on mainboard 20 sets up in heat-conducting medium, like this, when satisfying the leakproofness to internal components 21, because liquid heat-conducting medium's specific heat capacity is great, realize heat transfer through the natural convection heat transfer between component 21 and the liquid heat-conducting medium to the realization is to the cooling of component 21. Therefore, on one hand, the influence of outdoor environment factors can be shielded, the influence of dust impurities, environmental temperature and humidity, fan vibration and other factors can be reduced, and a more stable operation environment is provided for the components 21, so that the fault rate of the components 21 is reduced, the operation and maintenance frequency and the operation and maintenance cost are reduced, and the stability of the whole system is improved; on the other hand, the vehicle-road cooperative device 1 can also provide a heat dissipation requirement for the subsequently updated and updated component 21, and is favorable for modular deployment and rapid delivery.

Moreover, by arranging the heat pipe radiator 30 and attaching the evaporation part 31 of the heat pipe radiator 30 to the component 21, on one hand, rapid heat conduction can be realized for the component 21 with larger heat productivity, and the thermal resistance in the heat conduction process is lower; on the other hand, the condensation portion 32 is attached to the inner wall of the casing 10, so that the heat dissipation area of the heat pipe radiator 30 can be increased, heat can be quickly conducted to the outside from the closed cavity, the constant temperature of the working environment of the component 21 is ensured, and the working reliability of the vehicle-road cooperative equipment 1 is further improved.

In addition, compare in the car road cooperative equipment among the correlation technique and adopt the air-cooled heat dissipation mode, the car road cooperative equipment 1 of this application embodiment need not to set up the air-cooled radiator and can realize the natural heat dissipation to components and parts 21 to the energy consumption has been saved, the running cost has been reduced.

Therefore, the vehicle-road cooperative equipment 1 according to the embodiment of the application has good sealing performance and heat dissipation performance, high working stability and reliability and low subsequent maintenance cost.

In an example, referring to fig. 1 to 3 and the vehicle-road coordination device 1 described in the embodiments of the present application, the vehicle-road coordination device 1 of the embodiment of the present application may be an edge computing server.

In another example, the vehicle-road cooperation apparatus 1 may be disposed nearby a road for providing the vehicle-road cooperation service to the unmanned vehicle.

In one embodiment, the heat pipe radiator 30 further includes a refrigerant conveying portion 33, the refrigerant conveying portion 33 is connected between the condensing portion 32 and the evaporating portion 31, and a heat insulating layer is disposed on an outer surface of the refrigerant conveying portion 33.

For example, as shown in fig. 2, the refrigerant delivery part 33 may be configured in a pipe shape and connected between the condensing part 32 and the evaporating part 31. Specifically, the refrigerant conveying portion 33 includes a first refrigerant conveying pipe for conveying the refrigerant from the evaporation portion 31 to the condensation portion 32, and a second refrigerant conveying pipe for conveying the refrigerant from the condensation portion 32 to the evaporation portion 31. The first refrigerant conveying pipe and the second refrigerant conveying pipe are respectively provided with a heat insulation layer outside, and the heat insulation layers are made of heat insulation materials. Therefore, the heat exchange between the refrigerant and an external heat-conducting medium can be avoided in the process that the refrigerant flows in the first refrigerant conveying pipe or the second refrigerant conveying pipe.

In one embodiment, the wall of the casing 10 is configured as a hollow structure to define a refrigerant flow passage (not shown) that communicates with the internal cavity of the condensation portion 32.

For example, the refrigerant channel may be disposed on a wall body at the top of the casing 10, and the refrigerant channel has an input end and an output end, the input end is communicated with the internal cavity of the condensing portion 32, and the output end is communicated with the internal cavity of the evaporating portion 31 through a second refrigerant conveying pipe. After entering the refrigerant flow channel, the gaseous refrigerant in the condensing portion 32 exchanges heat with the outside through the wall body at the top of the casing 10, and after releasing heat and condensing, the refrigerant is converted from a gaseous state into a liquid state and flows back to the evaporating portion 31 through the refrigerant conveying portion 33 under the action of self gravity; the liquid refrigerant exchanges heat with the component 21 attached to the evaporation portion 31 in the evaporation portion 31, absorbs heat and evaporates, is converted from a liquid state into a gas state, and flows to the condensation portion 32 through the second refrigerant delivery pipe, thereby circulating.

The refrigerant flow channel communicated with the internal cavity of the condensation portion 32 is disposed in the wall body of the casing 10, so that the gaseous refrigerant in the condensation portion 32 enters the refrigerant flow channel and exchanges heat with the outside, thereby improving the flow path of the gaseous refrigerant, increasing the heat dissipation area of the gaseous refrigerant, improving the condensation efficiency of the gaseous refrigerant, and further improving the heat dissipation efficiency of the heat pipe radiator 30.

In one embodiment, the outer surface of the evaporation portion 31 is provided with a plurality of heat dissipation ribs 311, and the plurality of heat dissipation ribs 311 are spaced apart from each other.

For example, a first side surface of the evaporation portion 31 is attached to the component 21, the plurality of heat dissipation fins 311 may be disposed on a second side surface of the evaporation portion 31 away from the component 21, and/or the plurality of heat dissipation fins 311 may be disposed on at least one third side surface of the evaporation portion 31, where the third side surface is adjacent to the first side surface. Also, the plurality of heat dissipation ribs 311 may be disposed at equal intervals. Therefore, the contact area between the evaporator and the heat-conducting medium can be increased, the heat exchange efficiency between the evaporator and the heat-conducting medium is improved, the temperature of the component 21 and the heat-conducting medium around the component 21 is reduced, and the stable working temperature is improved for the component 21.

Alternatively, the height of the heat dissipation ribs 311 is less than or equal to 15mm, and the spacing between adjacent heat dissipation ribs 311 is greater than or equal to 5 mm.

It should be noted that, if the height of the heat dissipation fins 311 is greater than 15mm and the distance between adjacent heat dissipation fins 311 is less than 5mm, the cross-sectional area of the passageway formed between adjacent heat dissipation fins 311 is too large, and meanwhile, the distance between two adjacent heat dissipation fins 311 is too small, because the heat-conducting medium has a certain surface tension and flowing viscosity, the flow rate of the heat-conducting medium flowing along the passageway formed between two adjacent heat dissipation fins 311 is too low, thereby affecting the convection velocity of the heat-conducting medium and reducing the heat diffusion efficiency of the heat-conducting medium. Therefore, by setting the height of the heat dissipation fins 311 to be less than or equal to 15mm and the interval between adjacent heat dissipation fins 311 to be greater than or equal to 5mm, it is possible to ensure a greater rate of the heat transfer medium flowing along the passageway formed by two adjacent heat dissipation fins 311, thereby ensuring the convection velocity and the heat diffusion efficiency of the heat transfer medium.

Illustratively, the heat dissipation ribs 311 are telescopically arranged on the evaporation portion 31, i.e. the height of the heat dissipation ribs 311 relative to the evaporation portion 31 is adjustable. Therefore, the expansion amount of the heat dissipation fins 311, that is, the height of the heat dissipation fins 311, can be adjusted according to the heat exchange requirement.
