For strengthening radiating effect, then develop and water-cooled power converter, it is the water-cooled head that installing one is filled with cooling fluid on the central microprocessor of a motherboard or other heating electronic building brick, and see through conduit and link to each other with a cooling device, make liquid circulation this water-cooled head of flowing through by a pumping again, utilize heat exchange to reduce temperature with the heat energy dissipation that helps the heating electronic building brick, through after the heat exchange, the cooling fluid that temperature rises sees through that conduit flow to cooling device so that coolant temperature descends, and flows to the water-cooled head once more and carry out heat exchange.

Aforementioned cooling device generally has two water tanks, in between two water tanks, be communicated with plural metal drainage tube, when cooling fluid is back to cooling device through the water-cooled head, drainage tube provides the more contact area of cooling fluid to dissipate and the temperature reduction to help its heat energy, but, cooling fluid has the part aqueous vapor and evaporates in water tank after cold and hot exchange, be under the high temperature heat radiation for a long time and will make cooling fluid not enough and cause the radiating effect variation, and the electronic building brick that may cause generating heat is damaged because of overheated.

The utility model content

As shown in the above description, general water-cooled power converter gets off for a long time can be because of the cooling fluid evaporation causes the cooling fluid deficiency, makes the radiating effect variation.

In view of this, the purpose of this utility model is to provide a kind of cooling device, and it has a transparent tube can provide the big volume cooling fluid water yield and its transparent structure of mat to increase general water cooling chamber heat abstractor to be made for the usefulness of monitoring the cooling fluid water yield.

Desiring to reach the employed technological means of above-mentioned purpose comprises for making this cooling device: one first water tank has an inlet opening; One second water tank is with this first water tank and is arranged in parallel and has an apopore; The plural number drainage tube is mutually and is arranged in parallel, and this first water tank of vertical connection and second water tank; Be provided with a transparent tube between this first water tank and second water tank, be communicated with this first water tank and this second water tank.

Can install plurality of radiating fins between aforementioned each drainage tube to increase radiating effect; And this first water tank and second water tank can be separated into two rooms by a dividing plate respectively, and formation one is made a circulation and long current loop between each room and drainage tube, and the time that makes cooling fluid stay in drainage tube obtains than sufficient cooling time than length.

Transparent tube of the present utility model can provide big volume increasing the cooling fluid water yield of general water cooling chamber heat abstractor, and its transparent structure of mat is made for the usefulness of the monitoring cooling fluid water yield.

Embodiment

Please refer to Figure 1 and Figure 2, be the stereogram and the cutaway view of the utility model one preferred embodiment, this cooling device 1 comprises:

One first water tank 10, be to constitute by a hollow cylindrical case, in present embodiment, be provided with a dividing plate 12 in this first water tank 10 and be separated into one first room 101 and one second room 102, wherein be formed with first interface 13 that an inlet opening 11 and that is communicated with first room 101 is communicated with first room 101 on this hollow cylindrical case;

One second water tank 20, be to constitute and be by a hollow cylindrical case to be arranged in parallel with this first water tank 10, in present embodiment, be provided with a dividing plate 22 in this second water tank 20 and be separated into one the 3rd room 201 and one the 4th room 202, wherein be formed with second interface 23 that an apopore 21 and that is communicated with the 4th room 202 is communicated with the 3rd room 201 on this hollow cylindrical case;
