Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
As depicted in figs. 1 and 2, a kind of water cooling back board system, water inlet module 1, cooling including being set to cabinet exhaust outlet
Module 2 and water outlet module 3, water inlet module 1 includes the header tank 11 of distribution water, and conveys the water inlet pipe 12 of chilled water, into
Water pipe 12 is connected to header tank 11, and water inlet pipe 12 and header tank 11 constitute ring structure；Refrigerating module 2 includes 21 He of heat exchange coil
Multiple groups cooling water channel 22, heat exchange coil 21 cover cooling water channel 22, and cooling water channel 22 has water inlet end 221 and water outlet 222, into
Water end (W.E.) 221 is connected to water inlet pipe 12, and water outlet module 3 includes outlet pipe 31, and water outlet 222 is connected to outlet pipe 31.Header tank 11
Water flow can be subjected to equivalent distribution, water is delivered to by water inlet pipe 12 by cooling water channel 22 by water inlet 13, is protected
The flow of card each group cooling water channel 22 meets load needs；Meanwhile water inlet pipe 12 and header tank 11 constitute closed ring structure,
Water flow remains dynamic balance state, guarantees the uniform flow distribution of every group of cooling water channel 22, cabinet is avoided to will appear part
Hot issue.
The header tank in header tank and water outlet module 3 in water inlet module 1 is the same header tank 11.As shown in Fig. 2, cold
But water route 22 has multiple groups, and the water inlet end 221 of every group of cooling water channel 22 be connected to water inlet pipe 12, every group of cooling water channel 22 out
Water end (W.E.) 222 is connected to outlet pipe 31, and the chilled water in water inlet pipe 12 passes through cooling water channel 22, is then flowed out from outlet pipe 31.
As depicted in figs. 1 and 2, the ipsilateral cooling water channel 22 of multiple groups forms cooling unit 23, and multiple groups cooling unit 23 is arranged side by side
Setting, every group of cooling unit 23 are each equipped with heat exchange coil.It is ipsilateral to refer to vertical direction for cabinet.Cooling water channel
Setting group number depending on cabinet dimensions.Heat exchange coil uses finned tube exchanger, and heat exchange principle is: cooling water channel outer cover
There is fin, the cooling capacity of chilled water passes to the fin covered outside cooling water channel in cooling water channel, and the cooling capacity of fin is again with convection current
Mode pass to fin surface by cabinet be discharged hot-air, to achieve the purpose that cooling air.Traditional backboard is cold
But system is provided only with a cooling unit, and when cooling unit blocks, chilled water can not be by so that arrange cabinet
Hot-air out cools down, and hot localised points problem occurs, and now multiple groups cooling unit 23 is set side by side, every group of cooling unit 23
The area of covering is smaller, and cooling efficiency is higher.When wherein one or more heat exchange coils are damaged and can not be worked, other heat exchange
Coil pipe can continue to carry out cooling work.
Water inlet pipe has the first water inlet 131 and the second water inlet 132, the mode of communicating packet of water inlet pipe 12 and header tank 11
It includes:
The first: the first water inlet 131 and the second water inlet 132 are directly connected to header tank 11 respectively, using header tank
11 modes being directly connected to water inlet pipe 12,12 structure of water inlet pipe is simple, and header tank 11 need to be provided with it is consistent with water inlet quantity
Hole, as shown in Figure 4.
Second: header tank 11 is connect by the first connecting pipe 113 with water inlet pipe 12, and the first connecting pipe 113 shunts
Water is conveyed to each water inlet.The box structure that catchments in this kind of mode is simple, but need to be arranged between header tank and water inlet pipe
Y-shaped three-way pipe i.e. the first connecting pipe 113 of one connection header tank 11, the first water inlet 131 and the second water inlet 132, such as
Shown in Fig. 5.
Outlet pipe 31 and header tank constitute ring structure, and outlet pipe 31 has the first water outlet 311 and the second water outlet
312, the mode of communicating of outlet pipe 31 and header tank 11 be the first water outlet 311 and the second 312 mouthfuls of water outlet respectively directly with catchment
Case 11 is connected to；Alternatively, header tank 11 is connect by the second connecting pipe 313 with outlet pipe 31, the second connecting pipe 313 is Y type
Tee tube.When the blocking of certain of a certain water outlet of outlet pipe 31 or outlet pipe 31, the water after heat exchange avoids blocking pipeline,
Pass through the water after another water inlet discharge heat exchange of outlet pipe 31.
The water inlet pipe of traditional conveying chilled water is vertical element structure, and when a certain section of blocking of water inlet pipe, chilled water can not
By cooling water channel, to can not cool down to cabinet.And ring structure is set by water inlet pipe 12, it is blocked up when 12 a certain sections of water inlet pipe
When plug, chilled water avoids blocking pipeline, conveys chilled water to cooling water channel 22 by another water inlet of water inlet pipe 12.For example,
Cooling unit includes the first cooling unit 231 and the second cooling unit 232, and water inlet pipe 12 has the first water inlet 131 and second
Water inlet 132, when a certain section of blocking of the first water inlet 131 or water inlet pipe 12, chilled water enters from the second water inlet 132,
It is supplied water by circulating line to each group cooling unit.
As shown in Fig. 2, the water inlet end 221 of every group of cooling water channel is equipped with the valve 224 of control inflow.When in cabinet
Information technoloy equipment is not all turned on or according to information technoloy equipment temperature of outgoing air, the inflow of cooling water channel 22 is controlled by valve 224
Or the number of cooling water channel is opened, to realize the flow adjustment of Single Cabinet, realize accurate cooling capacity distribution.
As shown in Fig. 2, water inlet pipe 12 is square structure.Square structure water inlet pipe 12 facilitates installation and removal.
As shown in figure 3, header tank 11 connects water inlet manifold 111 and total return pipe 112.Header tank 11 connects water inlet manifold
111 with total return pipe 112, and the chilled water in water inlet manifold 111 is exported via header tank 11, then by water inlet pipe 12, cooling
The water inlet end 221 in water route 22 flows through heat exchange coil 21, exchanges heat with the hot-air of cabinet discharge, then going out from cooling water channel 22
Water end (W.E.) outflow, finally flows out from outlet pipe 31, into header tank 11, is collected to total return pipe 112.
As shown in figure 3, header tank 11, water inlet pipe 12, outlet pipe 31, cooling water channel 22, control valve 224 and heat exchange coil
21 constitute water cooling back board system, are installed on cabinet exhaust outlet.
When water cooling back board system works, chilled water enters header tank 11 from water inlet manifold 111, and header tank 11 distributes water and arrives
Water inlet pipe 12 enters heat exchange coil 21 by cooling water channel 22, and the chilled water after heat exchange is pooled to out from cooling water channel 22
Water pipe 31 leaves system from total return pipe 112 into header tank 11.Because any index circuit water inlet and water outlet with collection
Water tank 11 is connected, so the pressure drop of any loop is equal, the valve 224 even if on cooling water channel 22 guarantees any ring closing
The pressure drop on road is equal, so water flow remains that dynamic balance state, the water operation of each cooling water channel 22 are uniform.
Content described in this specification embodiment is only an enumeration of the implementation forms of the utility model concept, this is practical new
The protection scope of type should not be construed as being limited to the specific forms stated in the embodiments, the protection scope of the utility model also and
In those skilled in the art according to the utility model design it is conceivable that equivalent technologies mean.
