Specific embodiment

In conventional scheme, in order to cool down each detector module, need to be arranged one for each detector module Cold plate 100, be arranged on cold plate for the logical cold plate pipeline of cooling liquid stream and the inlet being connected with the cold plate pipeline and Liquid outlet, but in actual use, can not play true the problem of often will appear the malformations such as 100 positional shift of cold plate Real heat spreading function.Inventor it has been investigated that, in the installation in cold plate water route and in use, since inlet and liquid outlet position hold It easily shifts, leads to be fixed on cold plate pipeline and cold plate on cold plate and follow generation positional shift or deformation.

To solve the above problems, the utility model discloses a kind of cooling water channels of pet detector module comprising at least It pipeline is flowed through, flows through channel for for coolant liquid providing flow pipe, generated in detector module 200 with being taken away via cold plate Heat.Each flow through the input duct 120 and one that pipeline respectively includes cold plate pipeline 110 and is respectively communicated with cold plate pipeline Liquid outlet pipe 130, wherein cold plate pipeline 110 is fixed on 200 cold plate 100 of detector module, input duct 120 and liquid outlet pipe 130 are arranged in the shell 210 of detector module 200, to provide coolant liquid for the cold plate pipeline inside detector module 200 Entrance.

The corresponding input duct 120 of shell 210 is equipped with access way, the aperture of above-mentioned access way with liquid outlet pipe 130 It is arranged with input duct 120 and liquid outlet pipe 130, input duct 120 and the (inlet i.e. in conventional scheme of liquid outlet pipe 130 With liquid outlet) it is arranged in the shell 210 of detector module 200, on the one hand, in the installation for carrying out cold plate 100 and cold plate pipeline When, input duct 120 is inserted into liquid outlet pipe 130 in the corresponding access way of shell 210 respectively, be can be realized to inlet tube The installation of road 120 and liquid outlet pipe 130 positions, since input duct 120 and 130 installation site of liquid outlet pipe are clear, therefore can be square Just the installation of entire cooling water channel is efficiently realized；On the other hand, when in use, access way is to input duct 120 and liquid out Pipeline 130 is limited, it is avoided to occur the generation of drift condition in use, so can effectively prevent cold water pipes and Positional shift or deformation occur for cold plate 100.

Further, since component is more in detector module 200, installation space is limited, for relatively conventional scheme, this implementation In example, due to being mounted in detector housing 210, angle of turn becomes larger for input duct 120 and liquid outlet pipe 130, therefore cooling The processing of waterway pipe is more convenient.Simultaneously because input duct 120 and liquid outlet pipe 130 are arranged in detector housing 210, Increase for the relatively conventional scheme of heat dissipation area, also can effectively avoid the condensed water generated due to internal-external temperature difference.

Specifically, cold plate 100 is arranged inside detector module 200, for for each electronics in detector module 200 it is first Part radiates, and water-cooling channel is provided on cold plate 100, and cold plate pipeline 110 (for taking away the heat of cold plate absorption) is logical via water cooling Road embedded (cold plate pipeline 110 is flat tube) is laid out on cold plate 100 and in 100 continuous bend of cold plate, the formation of monolith cold plate 100 One smooth plane, input duct 120 are connected to cold plate pipeline 110 with liquid outlet pipe 130 and connect, and insert via access way Enter to the shell 210 of detector module 200, shell 210 and respectively spare interface is then pierced by, for connecting external water Case.Wherein, input duct 120 and liquid outlet pipe 130 both can be set in the same side body 210 of detector module 200, It may be provided in the different side bodies 210 of detector module 200, need to only realize position constraint.

As a preferred embodiment, in the present embodiment, one group is respectively provided in each detector module 200 and flows through channel, that is, is flowed It is corresponded through number of channels and detector module 200, in order to fabrication design.

As a preferred embodiment, in the present embodiment, 110 part vertical pipe of cold plate pipeline extends to 100 outside of cold plate simultaneously It is embedded on the shell 210 of detector module 200, the corresponding vertical component pipeline of the shell 210 of detector module 200 is separately set Water-cooling channel is set, thus when into the installation of cold plate 100 and water cooled pipeline, since cold plate 100 and water cooled pipeline are with whole knot The vertical component is embedded to the corresponding water-cooling channel of detector housing 210, can further realize cold plate 100 by structure The determination of installation site.

As a preferred embodiment, detector module 200 is assigned as multiple groups, flows through pipe between every group of detector module 200 Road is connected in series to form cooling cycle access；The inlet of the both ends of every group of cooling cycle access and external cooling water tank with go out Liquid mouth is respectively connected with, so that the coolant liquid in external cooling water tank flows through each detector module 200 in the group.

In each group detector module 200, between adjacent detector modules 200, liquid outlet pipe passes through respectively with input duct It is sequentially communicated by connecting tube 140 (hose), to form series via (i.e. cooling cycle access)；Each cooling cycle access is located at The liquid in-out pipeline at head and the tail both ends is connected to the inlet of external cooling water tank with liquid outlet.Setting is since coolant liquid is from outer in this way Portion's water tank distributes multichannel into each cooling cycle access, by way of very poor successively decrease, also divides the pressure of corollary equipment It dissipates.

Further, cooling cycle access is arranged in a one-to-one correspondence with inlet and liquid outlet quantity.I.e. each cooling cycle Access is connected to outer tank via different inlets with liquid outlet respectively respectively, in order to pipeline wiring.In the present embodiment, Each inlet can be separately positioned on outer tank at the inlet and outlet position of corresponding cooling cycle access with liquid outlet mouth.

This reality can be understood and used the above description of the embodiments is intended to facilitate those skilled in the art With novel.Person skilled in the art obviously easily can make various modifications to these embodiments, and saying herein Bright General Principle is applied in other embodiments without having to go through creative labor.Therefore, the utility model is not limited to Embodiment is stated, those skilled in the art's announcement according to the present utility model does not depart from the improvement that the utility model scope is made It should be all within the protection scope of the utility model with modification.
