Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a direct current is multiport converter for microgrid, includes box 1 of direct current is multiport converter for microgrid, and the inside of box 1 is provided with the heat sink, the heat sink include with 1 fixed mounting of box a plurality of refrigeration pieces 2 and install the air discharge fan 3 at 1 medial surface of box, wherein the refrigeration face fixed mounting of refrigeration piece 2 has lead temperature pole 15, and air inlet window and air-out window have been seted up respectively to the both sides face of box 1, and wherein the air-out window is just to the air-out face of air discharge fan 3.

The surface of box 1 is equipped with radiator unit, radiator unit includes heat exchange seat 4, heat exchange seat 4 fixed mounting is on the surface of box 1, and hug closely with the face that generates heat of refrigeration piece 2, one side fixed mounting that box 1 is close to the air-out window has heat exchange tube 5, first circulating pipe 6 and second circulating pipe 7 have been seted up respectively in the middle of heat exchange seat 4 and in the middle of the lateral wall around the box 1, and first circulating pipe 6, second circulating pipe 7 and heat exchange tube 5 establish ties each other and form the closed loop, first circulating pipe 6 simultaneously, be full of the coolant liquid in second circulating pipe 7 and the heat exchange tube 5, the fixed surface cover of heat exchange tube 5 is equipped with a plurality of heat radiation fins 8, the fixed circulating pump 9 that is provided with in the centre of heat exchange tube 5.

When using this converter, when the inside calorific capacity of converter is great, alright for refrigeration piece 2 and exhaust fan 3 circular telegram, refrigeration piece 2 will refrigerate, and lead temperature pole 15 with low temperature conduction, exhaust fan 3 is at the rotation in-process this moment, will form the negative pressure in box 1 is inside, this negative pressure will attract outside air to get into box 1 from the air inlet window inside, then will be blown out by exhaust fan 3, thereby form the air current in box 1 is inside, and then take away the inside heat of box 1, and simultaneously, the inside air flow in-process of box 1, the air can be through leading temperature pole 15 surfaces, thereby by the reduce temperature, so, when these cold air after the reduce temperature pass box 1 inside, alright cool down the electronic component of box 1 inside, thereby effectively guarantee whole converter steady operation.

In the operation process, the heat emitted by the refrigerating fins 2 is firstly transferred to the heat exchange seat 4, then is transferred to the cooling liquid in the first circulating pipe 6 through the heat exchange seat 4, the cooling liquid absorbing the heat flows through the second circulating pipe 7 and the heat exchange pipe 5 under the action of the circulating pump 9, finally returns to the first circulating pipe 6, when the cooling liquid flows through the second circulating pipe 7, the heat of the cooling liquid is dissipated to the side surface of the box body 1, then is dissipated to the air through the side surface of the box body 1, and when the cooling liquid enters the heat exchange pipe 5, part of the heat is transferred to the heat dissipation fins 8 through the heat exchange pipe 5 and then is transferred to the air again through the heat dissipation fins 8.

And because the heat exchange tube 5 is set up in the side close to the air-out window of the container body 1, therefore, when the air discharge fan 3 rotates, the produced wind will blow the surface of the cooling fin 8, this will accelerate the air flow velocity on the surface of the cooling fin 8, thus has increased the radiating effect of the cooling fin 8 effectively, and then further guarantee the refrigerating stability of the refrigerating fin 2, therefore further guarantee the job stabilization of the whole converter.

The air inlet window of box 1 is middle fixed mounting has filter screen 10, inlays the filter core 11 that is equipped with the detachable and is used for filtering the dust in the middle of the air inlet window of box 1 simultaneously, so, when the air got into box 1 inside from the air inlet window, the dust in the air will be held back on the surface of filter core 11 to can guarantee the inside cleanness of box 1 greatly, and then effectively protect the inside electronic component of box 1.

One side of the box body 1 close to the air inlet window is rotatably provided with a protective screen 12, the protective screen 12 is fixed with the box body 1 through a bolt 13, and when the protective screen 12 is fixed, the filter element 11 is covered by the protective screen 12 to limit the filter element 11, so that the filter element 11 can be prevented from falling.

The air outlet window of box 1 is fixed to be inlayed and is equipped with separation net 14, and separation net 14 can prevent that debris such as outside insect from getting into inside box 1 from the air outlet window, refrigeration piece 2 divide into two sets ofly, is the symmetric distribution at the upper and lower two sides of box 1, so, alright let whole converter possess better low temperature operational environment, heat exchange seat 4 corresponds with the group number of refrigeration piece 2, also has two, so, alright guarantee that two sets of refrigeration piece 2 all can be stable refrigerate.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
