Provided is a method for manufacturing a polymer fiber adsorbent having an MOF uniformly distributed in the matrix thereof, the method comprising the steps of: spinning a spinning dope comprising a polymer matrix and a metal precursor of an MOF to prepare a polymer fiber adsorbent precursor comprising the metal precursor; and contacting the polymer fiber adsorbent precursor with an organic ligand of the MOF to form an MOF in the polymer fiber adsorbent precursor. A polymer fiber adsorbent manufacturing method provided by an aspect of the present invention offers a method capable of easy synthesis of an MOF which is sensitive to water, thereby obtaining a polymer fiber adsorbent excellent in terms of adsorption performance and long-term stability.

Structured metal-organic framework fiber adsorbent for capturing carbon dioxide and manufacturing method therefor

Disclosed herein is a motor-driven compressor with an inverter that is connected with an external power source via a connector part and controls a driving part which drives a compressing part to compress fluid. A printed circuit board is provided between the connector part and the driving part. Thus, noise transmitted from the driving part to the connector part is reduced, so that it is possible to minimize the transmission of the noise to an external power source.

Electric compressor

Disclosed herein is an electric compressor including: a main housing () having therein a suction chamber into which low-temperature refrigerant is drawn; an inverter housing () including an internal seating surface () formed adjacent to the suction chamber, with at least one inverter element () fixed at a surface thereof to the internal seating surface () while making contact with the internal seating surface (), the at least one inverter element () conducting heat to the main housing (); and at least one heat dissipation cover () disposed toward the main housing () while facing another surface of the inverter element () and enclosing the inverter element (), the at least one heat dissipation cover () having therein a receiving space () in which the inverter element () is received.

An apparatus for cooling an inverter of a vehicle which receives power supplied from a vehicle battery and controls the rotation speed of a motor, wherein the apparatus includes an inverter housing configured to support the inverter, and a heat dissipation unit provided at a predetermined position in the inverter housing and configured to come into contact with an outer circumferential surface of the capacitor so that heat of the capacitor is transferred to the inverter housing.
