Description

Liquid cooling apparatus
Technical field
The present invention relates to utilize the cooling liquid cooling to produce the liquid cooling apparatus of the generating heat department of heat.
Background technique
In the past, what be widely known by the people usually was, possessed light sources such as lamp with high brightness luminescent and the light that light source sends was projected the projection type video display device of the projection lens on the screen.In addition, for the influence that suppresses effectively to cause because of heat that light source sends, projection type video display device possesses the liquid cooling apparatus of the cooling liquid utilized cooling light source.
Particularly, liquid cooling apparatus has the stream that cooling liquid flows and the radiator of the warm cooling liquid of cooling.In addition, liquid cooling apparatus has the conservation tank (below, be called conservation tank down) of the cooling liquid that the conservation tank (below, be called conservation tank) of the cooling liquid in the temporary transient storage inflow radiator and temporary transient storage flow out from radiator.
With reference to Fig. 1 so example of liquid cooling apparatus is described.As shown in Figure 1, liquid cooling apparatus has the pipe arrangement 23 of cooling objects 25 such as connecting light source and radiator 200, and makes liquid circulation via pipe arrangement 23, thus cooling cooling object 25.Also have, pump 24 passes out to cooling liquid in the pipe arrangement 23, cooling liquid circulation between cooling object 25 and radiator 200 thus.
Radiator 200 has the radiating fin 203 of pipe arrangement 202 and cooling cooling liquid in the radiator that cooling liquid passes through.In addition, by by fan 26 blowings, come cold sink 203.
Liquid cooling apparatus has the last conservation tank 204 and temporary transient the storage from the following conservation tank 205 of the cooling liquid of radiator outflow of the cooling liquid in the temporary transient storage inflow radiator 200.
In addition, be under the situation of above-below direction at the gravitational direction when having left standstill projection type video display device, last conservation tank 204 is arranged on radiator 200 tops, and following conservation tank 205 is arranged on radiator 200 belows.Thus, alleviate the load that cooling liquid is passed out to the pump 24 in the pipe arrangement 23.
Because the size of the above-below direction of projection type video display device is restricted, so can't increase upward conservation tank 204 and the size of the above-below direction of conservation tank 205 down.On the other hand, in order fully to guarantee the memory space of cooling liquid, need to increase upward conservation tank 204 and the capacity (volume) of conservation tank 205 down.
Therefore, usually, the size of the above-below direction (gravitational direction) of conservation tank 205 was big under the size of the left and right directions (substantially horizontal) of conservation tank 205 reached than last conservation tank 204 under last conservation tank 204 reached.
In addition, above last conservation tank 204, be provided with the coolant bottle 201 of storage cooling liquid, cooling liquid is injected into the coolant bottle 201 from water filling hole.Also have, good for the circulation that makes cooling liquid, and air layer (for example, the spy opens the 2002-357803 communique) is set on the top of coolant bottle 201.
At this,, also can be the hanging or portable projection type video display device in top as projection type video display device.The top hanging or portable projection type video display device in because projection type video display device towards change, so air enters in pipe arrangement 23 grades sometimes.Like this, because if air enters in pipe arrangement 23 grades, then the flow of cooling liquid reduces, so the cooling effectiveness of cooling object 25 descends.
Particularly on described in the conservation tank 204, because the size of above-below direction (gravitational direction) is littler than the size of left and right directions (substantially horizontal), so if projection type video display device (that is, liquid cooling apparatus) towards change, then air enters in pipe arrangement 23 grades easily.
Summary of the invention
A technological scheme of the present invention provides a kind of liquid cooling apparatus, and it is arranged in the device with the generating heat department that produces heat, and utilizes cooling liquid to cool off described generating heat department, it is characterized in that possessing: the coolant bottle of storing described cooling liquid; Cool off the radiator of described cooling liquid; The cooling tube of the stream of the described cooling liquid of conduct that is communicated with described coolant bottle and described radiator, on the substantially horizontal when having left standstill described device, described coolant bottle and described radiator in abutting connection with and be provided with, the size of the substantially horizontal of the described coolant bottle of the size of the gravitational direction of the described coolant bottle when having left standstill described device when having left standstill described the device is big.
Also have, " device is left standstill " is meant device is not arranged on the horizontal plane obliquely.
According to this feature because the size of the gravitational direction of coolant bottle is bigger than the size of the substantially horizontal of coolant bottle, so even liquid cooling apparatus under situation about changing, also can suppress air and enter cooling tube.In addition, can guarantee the capacity of coolant bottle.
A technological scheme of the present invention in described technological scheme of the present invention, is characterized in that, on the gravitational direction when having left standstill described device, described cooling tube is communicated with the middle body of described coolant bottle.
According to this feature, because cooling tube is communicated with the middle body of the coolant bottle of gravitational direction, so even the reversing up and down of liquid cooling apparatus also can suppress air and enter in the cooling tube.
A technological scheme of the present invention, in described technological scheme of the present invention, it is characterized in that, be under the situation of above-below direction with the gravitational direction that left standstill described when device, described coolant bottle has the shape of expanding upward and expanding from described middle body from described middle body downwards.
