DETAILED ACTION
Claim Rejections - 35 USC § 103
1. In the event that the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 1-5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Chen et al. US2023/0262930 in view of CN103411356 using PE2E Search for English translation.
Per claim 1 Chen et al. teaches a control device for a heat dissipation of a server (see fig.1), configured for heat dissipation of the server ([0031]) and comprising: a box body (110, see fig.1); a cover plate (160), connected with the box body (see fig.1) and configured to close the box body ([0046]); a heat dissipation working medium (202), arranged in the box body (see fig.1) and configured to immerse the server (204; [0051], [0053], see fig.1); and a condensing module (130), arranged in the box body (see fig.1) and comprising: a condensing pipe (132; [0034]) arranged in the box body and configured to assist phase change of the heat dissipation working medium ([0034], [0056] & [0058]), so as to achieve heat dissipation circulation ([0034], [0056] & [0058]); and a flow guide driving member (140; [0045]), arranged towards the condensing pipe (132) and configured to provide a driving force to control a gaseous heat dissipation working medium to flow towards the condensing pipe (see fig.1-2), so as to prevent the gaseous heat dissipation working medium from impacting the cover plate when the cover plate is closed (see fig.1) and prevent the gaseous heat dissipation working medium from leaking to an outside of the box body when the cover plate is opened ([0041]-[0042], “based on the Coanda effect, the gaseous heat dissipation working medium would stick to the wall and the condenser and back to the coolant, thus preventing the gaseous heat dissipation working medium from leaking outside of the box body when the cover plate is opened”); wherein the condensing module further comprises a gas-liquid separator (154, see fig.1); the gas-liquid separator is arranged at an outlet of the flow guide driving member (see fig.1), and the gas-liquid separator is configured to separate an air and a droplet-shaped heat dissipation working medium (see fig.1, “Examiner asserts that the gas-liquid separator 154 is configured/capable to separate an air and a droplet-shaped heat dissipation working medium”).
Chen et al. does not explicitly teach a condensing coil
CAI et al. however discloses a condensing coil ([0003])
It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to have a condensing coil be made of condensing pipes, because condensing coils are heat exchangers made from condensing pipes to transfer heat from a refrigerant (or other fluid) to condense gas back into a liquid.
Per claim 2 Chen et al. in view of CAI et al. teaches the control device for the heat dissipation of the server as claimed in claim 1, wherein the flow guide driving member (140) is arranged at a side close to an inlet of the condensing coil (see fig.1).
Per claim 3 Chen et al. in view of CAI et al. teaches the control device for the heat dissipation of the server as claimed in claim 2, wherein an accommodating space is formed between the condensing coil and the box body (see fig.1), the flow guide driving member is arranged in the accommodating space, and the condensing coil covers the flow guide driving member in an arrangement direction of the server (see fig.1).
Per claim 4 Chen et al. in view of CAI et al. teaches the control device for the heat dissipation of the server as claimed in claim 1, wherein the condensing coil is an S-shaped coil ([0006]).
Per claim 5 Chen et al. in view of CAI et al. teaches the control device for the heat dissipation of the server as claimed in claim 1, wherein the gas-liquid separator with the first baffle plate and is arranged at a preset included angle relative to the first baffle plate (see fig.1).
Claim(s) 6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Chen et al. US2023/0262930 in view of CN103411356 using PE2E Search for English translation as applied to claim 1 and further in view of Jing et al. US2019/0166725.
Per claim 6 Chen et al. in view of CAI et al. teaches the control device for the heat dissipation of the server as claimed in claim 1,
Chen et al. in view of CAI et al. does not explicitly teach wherein the device further comprises a ventilation valve, wherein the ventilation valve is arranged on the cover plate, and an air separated by the gas-liquid separator is discharged out of the box body through the ventilation valve.
Jing et al. however discloses wherein a device further comprises a ventilation valve ([0059]-[0060]), wherein the ventilation valve is arranged on the cover plate, and an air separated by the gas-liquid separator is discharged out of the box body through the ventilation valve ([0079]).
It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to have a ventilation valve as taught by Jing et al. in the control device of Chen et al. in view of CAI et al., because it allows effective pressure relief within the box body.
