Abstract: A metal pole plate sealing structure for a fuel cell is disclosed, as well as a fuel cell using this structure. The metal pole plate sealing structure for a fuel cell includes a metal pole plate, a membrane electrode assembly and a sealing rubber body. The metal pole plate has a sealing rubber groove. The sealing rubber body is accommodated in the sealing rubber groove. The sealing rubber groove, the sealing rubber body and a frame of the membrane electrode assembly cooperate with each other to seal an internal space enclosed when the metal pole plate and the membrane electrode assembly are pressed together. An inner surface of the sealing rubber groove has a positioning unit which makes it easier to fix an installation position of the sealing rubber body in the sealing rubber groove.

Abstract: The present disclosure relates to an air-conditioning outdoor device and an air conditioner unit. The air-conditioning outdoor device comprises: an outdoor unit housing; a primary air return port and an air outlet port provided on a front panel on a side of the outdoor unit housing away from an installation wall; and a supplementary air return port provided on a side panel of the outdoor unit housing adjacent to the front panel; wherein the primary air return port and the supplementary air return port both communicate with an air return chamber inside the outdoor unit housing. The air-conditioning outdoor device of the present disclosure can effectively increase the air flow volume through the air port of the air-conditioning outdoor device.

Abstract: The present disclosure has disclosed an water pump of an air conditioner as well as a method and device for controlling the same, wherein the method for controlling an water pump of an air conditioner comprises: obtaining a state of a liquid level switch of the air conditioner, a state of operation of the air conditioner and an outdoor ambient temperature; and determining a turn-on timing of the water pump of the air conditioner according to the state of the liquid level switch of the air conditioner, the state of operation of the air conditioner and the outdoor ambient temperature obtained. The present disclosure solves the problem that the turn-on time of the water pump of the air conditioner in the prior art is not smart enough, so as to make the turn-on time of the water pump of the air conditioner more intelligent, whilst improving the safety of the water pump of the air conditioner is improved, and saving the energy.

Abstract: The present disclosure relates to an embedded type air conditioner outdoor unit and an air conditioner, wherein the embedded type air conditioner outdoor unit is configured to be embedded within a wall of a building, and the embedded type air conditioner outdoor unit comprises a heat exchanger, which includes a first inlet for introducing a refrigerant and a second inlet for introducing a heat exchange medium to perform heat exchange with the refrigerant. By applying the technical solution of the present application, in which the heat exchange medium is used to perform heat exchange with the refrigerant, the embedded type air conditioner outdoor unit of the present embodiment may be used without a fan system, so that the embedded type air conditioner outdoor unit has reduced vibration and noise.

Abstract: An air-conditioner outdoor device and an air-conditioner unit are provided. The air-conditioner outdoor device includes a casing and a heat exchanger, wherein the heat exchanger is disposed within the casing, a front plate of the casing is provided with an air outlet and two air inlets, the air outlet is located between the two air inlets, the heat exchanger is positioned closer to the front plate relative to a rear plate of the casing and faces the air outlet, and air flow entering the casing from the air inlets flows out of the casing from the air outlet after flowing through the heat exchanger. The air-conditioner unit comprises the air-conditioner outdoor device. The air-conditioner outdoor device of the present application improves the air intake and outlet manners to facilitate the installation of the air-conditioner outdoor device in a mounting hole through a wall and indoors.
