The radiating efficiency that radiator must be increased generally will use water-cooling system quickly to export thermal energy, please refer to TaiWan, China bulletin
M556996 patent, basic structure are a kind of existing water-cooled radiating structure, it includes a chambers as shown in Fig. 1
Body 1 and a radiator 2, the cavity 1 have a chamber 3 passed through for coolant liquid (not shown), which, which has, protrudes into this
Multiple heat-exchanging fins 4 of chamber 3, by the radiator 2 for contacting high power electronic element (not shown), and high power is electric
Heat caused by subcomponent is quickly taken away by the coolant liquid.
For the information equipment with multiple high power electronic elements, earliest period, which is that setting, covers water-cooling system, so
And its not only setup cost is high, difficult in maintenance and information equipment may not have enough spaces that can accommodate to cover water cooling systems more
System；Therefore, multiple radiators are arranged using a set of water-cooling system in the way of concatenated in someone, to take away multiple high powers simultaneously
The heat that electronic component generates, however the heat exchanger effectiveness of radiator and the temperature difference are closely bound up, for being located at water-cooling system end
Radiator for, since the temperature of coolant liquid has built up, the temperature difference for carrying out heat exchange is smaller, thus radiating efficiency is obvious
Less than the radiator positioned at water-cooling system front end, thus lead to the high power to radiate using water-cooling system end radiator
Electronic component, temperature can be significantly higher, and detracts its stability and service life.
Utility model content
The main purpose of the utility model is to provide a kind of tandem water-cooling radiating structure, dissipate at least two
Hot device, and comparable heat dissipation effect can be actually provided.
In order to achieve the above object, the utility model is a kind of tandem water-cooling radiating structure, it includes at least second radiators, one
Heat exchanger, a pumping, a coolant liquid and a fluid circuit, wherein the fluid circuit is connected at least second radiator, heat friendship
Parallel operation and the pumping and form a circulation loop, at least second radiator is respectively provided with different densities and is distributed in the circulation loop for this
An interior radiating fin, and the coolant liquid is filled in the circulation loop, and the coolant liquid by the pumping driving and in this
Circulation loop internal circulation flow, and in the circulation loop along the flow direction of the coolant liquid, this of at least second radiator dissipate
The Density Distribution of hot fin increases with the distance forward far from the heat exchanger.
Above-mentioned tandem water-cooling radiating structure, wherein the pumping is set to the dirty place of the heat exchanger.
Above-mentioned tandem water-cooling radiating structure, wherein the heat exchanger has the water inlet for being connected to the circulation loop.
Above-mentioned tandem water-cooling radiating structure, wherein the density of at least radiating fin of second radiator more considers
It corresponds to the calorific value of the heat source of installation and determines.
Above-mentioned tandem water-cooling radiating structure, wherein the heat exchanger, which has, enters water for the one of fluid circuit connection
Mouth and a water outlet, and the height of the water outlet is lower than the height of the water inlet.
Accordingly, the utility model allows the radiating fin density with higher of the radiator far from the heat exchanger to divide
Cloth, thus while the coolant liquid temperature with higher far from the heat exchanger and cause radiating efficiency low, however it is higher
The radiating fin of density can provide higher radiating efficiency, therefore can compensate radiating efficiency caused by coolant liquid heating
Low problem, and then allow the practical heat dissipation effect of different radiators is approximate and has effects that equalizing temperature, it is avoidable
The high power electronic element to be radiated using water-cooling system end radiator has temperature higher and detract stability and service life
Problem.

Specific embodiment
Detailed description and technology contents in relation to the utility model, now just cooperation schema is described as follows:
It is the structure chart and structure partial exploded view of one preferred embodiment of the utility model shown in please refer to figs. 2 and 3,
As shown, the utility model is a kind of tandem water-cooling radiating structure, it includes second radiator 10A, 10B, a heat exchanger
20, a pumping 30, one coolant liquid 40 and fluid circuit 50, wherein the fluid circuit 50 series connection second radiator 10A, 10B, this
Heat exchanger 20 and the pumping 30 and form a circulation loop 60, the second radiator 10A, 10B be respectively provided with different densities and point
Radiating fin 11A, the 11B being distributed in the circulation loop 60, and the coolant liquid 40 is filled in the circulation loop 60, and this is cold
But liquid 40 by the pumping 30 driving and in 60 internal circulation flow of circulation loop；And in the circulation loop 60 along the cooling
The flow direction of liquid 40, the Density Distribution of the radiating fin 11A, 11B of the second radiator 10A, 10B are somebody's turn to do with forward separate
The distance of heat exchanger 20 and increase, as shown in figure 3, be located at upstream radiating fin 11B forward far from the heat exchanger 20
Distance compared be located at downstream radiating fin 11A it is short, therefore radiating fin 11B have sparse Density Distribution.More into
One step, the radiating fin 11B that the utility model makes way for upstream has sparse density, therefore the coolant liquid 40 can be with
Smoothly by radiating fin 11B, back pressure will not be generated at radiating fin 11B, the stream of the coolant liquid 40 can be increased
Amount, and improving heat radiation efficiency.
In addition, the utility model is to meet different high power electronic elements (i.e. different heat sources), there is different heat amount
Use demand, the density of the radiating fin 11A, 11B of the second radiator 10A, 10B of the utility model more can be considered pair
The calorific value for the heat source that should be installed and determine, in more detail, if the radiating fin 11A, 11B couple of the radiator 10A, 10B
The calorific value for the heat source that should be installed is larger, can it is appropriate promoted the radiating fin 11A, 11B density, if otherwise calorific value compared with
It is small, and the density appropriate for reducing the radiating fin 11A, 11B, the target of second radiator 10A, 10B samming is allowed to meet.
As also shown in fig. 2, which can be set in the dirty place of the heat exchanger 20, and such coolant liquid 40 can be first
Cool down by the heat dissipation of the heat exchanger 20 using the pumping 30, the coolant liquid 40 compared with low temperature can be allowed to pass through the pumping
