A heat exchanger includes a heat transfer tube functioning as a flow path for refrigerant and also includes metal fins. The metal fins transmit heat of the heat transfer tube to air and have pores that are open inward from the surfaces of the metal fins and absorb and release moisture in the air when relative pressure is in the range of 0.1 - 0.9. The pores have a diameter in the range of 1 - 20 nm and a depth in the range of 1 - 100 mu m.

A rotor (30) comprises a rotor core (31) having electromagnetic steel sheets laminated, six permanent magnets (32) buried axially in the rotor core (31) and arranged substantially in a regular hexagon shape in the circumferential direction, rivets (33) arranged near and radially inside of the apexes of the regular hexagon formed of the six permanent magnets (32), and extending therethrough in the axial direction to fasten the rotor core (31), and through holes (34) formed between the rivets (33) of the rotor core (31) and extending axially through the rotor core (31). The through holes (34) are formed in the rotor core (31) radially inside of the central portions of the permanent magnets (32).

The invention relates to a battery (8), consisting of a plurality of individual cells (1), the reciprocal housing plates (2.1, 2.2) of which, preferably conducting heat well, are positioned at a distance from each other at least in sections so as to form fluid-permeable flow-through channels (9). According to the invention, a fluid flow guiding unit (7) is disposed on at least one side of the edge (5.1) of an individual cell housing (2) in an individual cell (1).

The invention provides a bi-directional seal low-flow-resistance stop valve. The stop valve comprises a valve casing, valve flaps, a valve rod and an executing mechanism; the valve casing is provided with a valve chamber, the valve chamber comprises two openings that are an inlet and an outlet, and the inlet and the outlet of the valve chamber are arranged relatively and are arranged at the two sides of the valve chamber respectively; the number of the valve flaps are two, and the valve flaps are arranged in the valve chamber of the valve casing; one end of the valve rod is connected with the executing mechanism which is arranged outside the valve chamber, the executing mechanism possesses a driving force, and the other end of the valve rod stretches into the valve chamber and is connected with the two valve flaps; the two valve flaps are matched with the inlet and the outlet of the valve chamber respectively to open or close the inlet or outlet of the valve chamber; when the two valve flaps open in a proper place, the flaps are located at the outside of a flow channel formed by the inlet and the outlet of the valve chamber. By the arrangement of the two valve flaps which are correspondingly matched with the inlet and the outlet of the valve chamber respectively, the block valve can be sealed bi-directionally; when the two valve flaps open in a proper place, the flaps are located at the outside of the flow channel formed by the inlet and the outlet of the valve chamber, and the flow of fluid cannot be blocked by the valve flaps, so that low flow resistance is realized.

The invention provides an ionic wind radiating device, which is characterized by comprising a power supply and a radiating net formed by mutually intersecting a first group of conductive wires comprising two or more than two conductive wires and a second group of conductive wires comprising two or more than two conductive wires, wherein the first group of conductive wires are electrically connected to one output end of the power supply; the second group of conductive wires are electrically connected to another output end of the power supply; in addition, at the position of each intersection, the first group of conductive wires have bumps which face the same direction and are vertical to the plane of the radiating net so as to stride over the corresponding second group of conductive wires which are intersected with the first group of conductive wires, and the first and the second groups of conductive wires are mutually insulated.

A centrifugal compressor and a method of manufacturing an impeller, the method wherein a projected part (17) is formed at the approximately radial center part of the impeller (11) on the negative pressure surface side of its a blade (16) so as to form a curve from the leading edge part (A) to the throat part (B) thereof. The projected part (17) is formed to be curved and then to be flat from the throat part (B) to the trailing edge part thereof. The projected part (17) is formed at a position where the relative inflow velocity of the fluid into the impeller (11) is nearly 1 in Mach number Ma. Thus, since an operating efficiency can be increased and an applicable flow range can be increased, the performance of the impeller can be increased.

A fuel filling device for a vehicle fuel tank has a fuel filling opening (15a) in an upper wall (3a) of a vehicle fuel tank (3) for containing ethanol fuel as engine fuel, and also has a fuel filling guide tube (15) extending from the fuel filling opening (15a) into the fuel tank (3) and receiving a fuel filling gun (G). A fuel filling guide tube (15) has a flame arrester (21) for covering a lower opening of the fuel filling guide tube (15) and permitting flow of fuel while preventing entry of fire, and also has a gun stopper (20) for preventing the fuel filling gun (G) inserted into the fuel filling guide tube (15) from making contact with the flame arrester (21). Without the use of a long fuel filling guide tube, the flame arrester can be protected against damage by the fuel filling gun inserted into the fuel filling opening.

An air conditioner according to the invention comprises the following components: a body which is formed with an air suction inlet; a discharge outlet body which is installed on the body with a liftable mode and is formed with an air discharge outlet; a plurality of left-and-right wind direction adjusting components which are rotatablely installed on the inner side of discharge outlet body; a left-and-right rotation mechanism which rotates the plurality of left-and-right wind direction adjusting components; and a supporting member which is formed with a plurality of supporting feet that support the left-and-right wind direction adjusting components and is formed with a path for the passing of air among the plurality of supporting feet. The left-and-right wind direction adjusting components are positioned at the deep part of inner part of discharge outlet body and can prolong the guiding length. Therefore the air conditioner according to the invention has the advantage that the discharged air can be discharged and diffused to a far position and the air flow is smooth.
