Abstract: A method of diagnosing a pipe includes diagnosing, by a computer, a state of a pipe from an updated model based on change in temperature of the pipe calculated from the model in a case where the pipe is heated in the model obtained by modeling a heat transfer behavior of an inside of the pipe containing deposition by using an equivalent circuit and change in temperature of the pipe measured in a case where the pipe is heated.

Abstract: A liquid cooling apparatus includes a plurality of system boards each having a first surface and a second surface opposite the first surface, each of the system boards having at least one electronic component mounted on the first surface, a cooling plate attached to the electronic component and having a pathway formed therein through which coolant flows, one or more heat conductive members penetrating through any given one of the system boards, and a heat dissipating member disposed on the second surface of any given one of the system boards and connected to the one or more heat conductive members, wherein an emissivity of the heat dissipating member is higher than an emissivity of the one or more heat conductive members.

Abstract: An object in one aspect is to supply, to an electronic device, cooling fluid of a temperature lower than a temperature of an environment in which the electronic device is set. A cooling system has an electronic device, a supply pipe, a discharge pipe, and a heat exchange portion. The supply pipe supplies cooling fluid to the electronic device, and the discharge pipe discharges cooling fluid from the electronic device. The heat exchange portion exchanges heat between the supply pipe and the discharge pipe in a case in which a temperature of cooling fluid flowing through the supply pipe is lower than a dew point of an environment in which the electronic device is set.
