Embodiment
Core of the present invention provides a kind of vehicle-mounted charge machine, to improve rate of heat dissipation, reduces the space hold rate simultaneously.
In order to make those skilled in the art person understand the present invention program better, the present invention is done further detailed description below in conjunction with accompanying drawing and execution mode.
Please refer to Fig. 1-Fig. 4, wherein, the charger main body structure sketch map of the vehicle-mounted charge machine that Fig. 1 provides for the embodiment of the invention; The internal structure sketch map of the vehicle-mounted charge machine that Fig. 2 provides for the embodiment of the invention; The structural representation of the vehicle-mounted charge machine that Fig. 3 provides for the embodiment of the invention; The structural representation of the following coldplate of the vehicle-mounted charge machine that Fig. 4 provides for the embodiment of the invention.
The embodiment of the invention provides a kind of vehicle-mounted charge machine; Comprise charger body 1 with first power circuit board 21 and second power circuit board 22; Also comprise the inlet 33 and liquid outlet 34 that are arranged on the charger body 1, and the cooling device 3 that is arranged on last coldplate 32 of having of charger body 1 inside and following coldplate 31.Wherein, First power circuit board 21 is installed on the coldplate 32; Second power circuit board 22 is installed in down on the coldplate 31; Between last coldplate 32 and following coldplate 31, be provided with the cooling duct 35 that is used for circulating cooling liquid, and the two ends of cooling duct 35 are connected with inlet 33 and liquid outlet 34 respectively.
For powerful vehicle-mounted charge machine, its volume and heat dissipation capacity are all very big, have been difficult to satisfy the requirement of charger heat radiation through traditional heat radiation.In order to improve rate of heat dissipation, first power circuit board 21 on the charger body 1 and second power circuit board 22 are installed in respectively on coldplate 32 and the following coldplate 31, promptly cooling device 3 is installed between first power circuit board 21 and second power circuit board 22.For the circulation of giving cooling fluid provides passage, between last coldplate 32 and following coldplate 31, be provided with cooling duct 35, and the two ends of cooling duct 35 are linked to each other with liquid outlet 34 with inlet 33 respectively.During charger work; The heat that first power circuit board 21 distributes can be absorbed by last coldplate 32; The heat that second power circuit board 22 distributes can be by coldplate 31 absorptions down, and the cooling duct that between last coldplate 32 and following coldplate 31, is provided with is full of cooling fluid for 35 li, make the cooling fluid of 35 li of cooling ducts absorb the heat of going up coldplate 32 and following coldplate 31 absorptions; The cooling fluid that will absorb heat is then discharged from liquid outlet 34, accomplishes the cooling to the vehicle-mounted charge machine.Preferably, above-mentioned cooling fluid can be water.
The specific heat ratio air of cooling fluid big can be dispelled the heat to the vehicle-mounted charge machine through the circulation of cooling fluid fast, effectively improved rate of heat dissipation.During installation, first power circuit board 21 and second power circuit board 22 are installed in respectively on coldplate 32 and the following coldplate 31, then charger lower cover 11 and charger upper cover plate 12 are installed, be about to cooling device 3 and be arranged on vehicle-mounted charge machine inside.It is thus clear that, the cooling device 3 and the mode of charger body 1 integrated setting can effectively be saved the space, solved the problem of car load layout.
For the ease of installing, cooling duct 35 is arranged on down on the coldplate 31, that is, under installing, behind the coldplate 31 cooling duct 35 is laid on the following coldplate 31, will go up coldplate 32 again and install.Go up the heat that passes over by first power circuit board 21 and second power circuit board 22 respectively on coldplate 32 and the following coldplate 31 through the absorption of the cooling fluid in the cooling duct 35.
In order to save cost, cooling duct 35 and following coldplate 31 as one, and are gone up coldplate 32 and sealed with cooling duct 35 and link to each other.The cooling duct 35 and the following coldplate 31 of the vehicle-mounted charge machine that provides in the embodiment of the invention are set to one, promptly digging out the cooling duct 35 that is used for liquid circulation as requested on the coldplate 31 down, cooling duct 35 are hidden in down in the coldplate 31.Simultaneously, will go up 35 sealings of coldplate 32 and cooling duct and link to each other, as the seal cover board of cooling duct 35 cooling duct 35 sealed even go up coldplate 32.In this scheme, cooling fluid enters into cooling duct 35 from inlet 33, in cooling duct 35, absorbs heat and discharges from liquid outlet 34.
In order to absorb heat faster; In the embodiment of the invention cooling duct 35 is set to the passage of bending; The cooling duct 35 and the contact area of following coldplate 31 and last coldplate 32 are increased, thereby increased the contact area of cooling duct 35 and first power circuit board 21 and second power circuit board 22.Because the increase of contact area when cooling fluid is cooled off the vehicle-mounted charge machine, has effectively improved radiating effect.
Temperature rise according to vehicle-mounted charge machine full-load power and efficient and liquid outlet 34 cooling fluids; Through calculating the heat dissipation capacity that can draw charger; According to the different radiating amount flow velocity of cooling fluid in cooling duct 35 and the speed of circulation can be set, to satisfy the different radiating requirement.
Because the main heating of vehicle-mounted charge machine partly is the heating components and parts of first power circuit board 21 and second power circuit board 22, therefore these heating components and parts are main thermals source.In order to reduce the temperature of vehicle-mounted charge machine; Can directly absorb the heat of the heating components and parts generation of first power circuit board 21 and second power circuit board 22; Given this; In the embodiment of the invention heating components and parts of first power circuit board 21 and the heating components and parts of second power circuit board 22 are installed in respectively on coldplate 32 and the following coldplate 31, have avoided the energy waste of cooling device 3.
In order further to reduce the occupancy in space, can confirm to go up the size of coldplate 32 and following coldplate 31 according to the size of the heating components and parts of first power circuit board 21 and second power circuit board 22.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments among this paper.Therefore, the present invention will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
