Description

FIELD OF THE INVENTIONThe present invention relates to a liquid cooling apparatus, and more particularly to a liquid cooling apparatus having a pump attached thereto, which is easily replaceable.BACKGROUND OF THE INVENTIONTWM508705 discloses a liquid cooled heat dissipation structure. The liquid-cooled heat dissipation structure includes a heat dissipation module and a water supply module. The water supply module includes an outer cover disposed on the heat dissipation module and at least one pump disposed in the outer cover. An inner space of the outer cover is divided into a first independent space adjacent to the heat dissipation module and a second independent space that is remote from the heat dissipation module and does not communicate with the first independent space. The pump includes a stator disposed in the first independent space and a rotor disposed in the second independent space, the rotor being disposed closer to the heat dissipation module than the rotor. The outer cover of the water supply module needs to cooperate with an outer side of the heat dissipation module to form a space for accommodating the pump. This means that the water supply module does not have an independent casing. Therefore, such a construction is not favorable for the replacement of the pump.SUMMARY OF THE INVENTIONA principal object of the invention is to solve the problem that the conventional structure is not conducive to later replacement or maintenance.To achieve the above object, the invention provides a liquid cooling apparatus for conveniently exchanging a pump, which comprises a heat exchange block and a pump. The heat exchanger block includes a body, two pipe connection ports formed on the body, a heat exchanger chamber formed in the body, a passage formed in the body and separated from the heat exchanger chamber, a first pump installation port formed on the body, and a second pump installation port formed on the body. One of the two pipe connection ports forms a first water passage with the passage and the first pump installation port, and the other of the two pipe connection ports forms a second water passage with the heat exchange chamber and the second pump installation port. The pump is mounted on the heat exchanger block, the pump includes a housing that is relatively separable from the body and two pump connection ports located on the housing, the two pump connection ports are connected to the first pump installation port and the second pump installation port, respectively, and the pump is connected to the first water passage and the second water passage.In an embodiment, the heat exchanger block includes a heat conducting plate provided on the body and a heat conducting fin set provided on the heat conducting plate.

Moreover, the two pipe connection ports 212 are respectively connected to two liquid passages 31, and the two liquid passages 31 can be connected to a heat dissipation radiator (not illustrated in the figures), so that the liquid cooling device 20, the two liquid passages 31, and the heat dissipation radiator form a closed heat dissipation circulation system.Referring again to FIGS. 2, 3, 4 and 5, the pump 23 is fixed to the heat exchange block 21. The pump 23 is composed of a housing 231 separable from the body 211 and two pump communication ports 232 provided on the housing 231. The pump 23 is connected to the first water passage 24 and the second water passage 25 so that a working fluid flows through the pump 23 in either the first water passage 24 to the second water passage 25 or the second water passage 25 to the first water passage 24. It is to be understood that the heat exchanger block 21 of the present invention uses one of the two pipe connection ports 212 as an inlet of the working fluid and the other of the two pipe connection ports 212 as an outlet of the working fluid for the working fluid flowing in the first water passage 24 and the second water passage 25 in a one-way flow.

The pump 23 according to the invention is intended to be fixed to the heat exchanger block 21, and the housing 231 of the pump 23 is independent of the body 211 of the heat exchanger block 21, so that the housing 231 does not have to cooperate with the body 211 to define a required space. According to the present invention, the pump 23 can be replaced by separating the two pump connection ports 232 of the pump 23 from the first pump installation port 215 and the second pump installation port 216, without disassembling the body 211. During maintenance or replacement of the pump 23 with different specifications, the pump 23 may be assembled according to implementation requirements to reduce the degree of limitation by other structures. Referring to FIGS. 3, 4, 5, and 6, the heat exchanger block 21 includes a heat conducting plate 217 provided on the body 211, and a heat conducting fin set 218 provided on the heat conducting plate 217 and located in the heat exchanger chamber 213. The heat exchanger block 21 forms a heat conduction through the heat conducting plate 217 and the component 30 to be dissipated. A heat conducting adhesive layer 32 can be arranged between the heat conducting plate 217 and the component 30 to be dissipated. Moreover, the heat plate 217 and the heat fin set 218 may be integrally formed or formed into a component by machining. The heat conducting plate 217 and the heat conducting fin set 218 are both made of metal and have good heat conductivity. In one embodiment, the thermal plate 217 and the thermal fin set 218 may each be made of copper. The heat-conducting fin set 218 includes a plurality of heat-conducting fins arranged at intervals, and the directions and positions of the plurality of heat-conducting fins are determined by a flow path formed in the heat exchange chamber 213.
