Abstract: A modular cross flow fan comprises a housing, a cross flow fan and a motor. The housing has an upper wall, a lower wall and two side boards. The housing is formed with an accommodating space, an inflow opening and an outflow opening. The direction of inflow and the direction of outflow lie in a line. The cross flow fan is disposed in the accommodating space. The motor is disposed at the housing and connected to the cross flow fan. Furthermore, an air conditioning device is provided, comprising modular cross flow fan, a flow channel and a heat exchanger. The flow channel is joined to the inflow opening. The heat exchanger is disposed in the flow channel proximal to the inflow opening. Ambient air can flow horizontally through the flow channel, the inflow opening, and into the housing.

Abstract: An electric heater comprises a main body, a panel, a cross flow fan, a motor and a heating element. The main body is made by aluminum extrusion and has a bottom board and a front board. The bottom board and the front board define an air outlet therebetween. The panel is disposed on the main body and is formed with a plurality of air inlets. The cross flow fan is rotatably disposed in the main body. The motor is disposed on the main body and connected to the cross flow fan. The heating element is disposed in the main body. By this configuration, the main body is resistant to high temperature, the temperature of the heating element is not as limited, providing a preferred heating effect, structural strength and is less easily damaged.

Abstract: A modular cross-flow-fan device comprises a housing, at least two cross flow fans and a motor. The housing is an extruded aluminum piece having a first wall and a second wall, and is formed with an air inlet and an air outlet. The cross flow fans are disposed in the housing and connected to each other. The motor is disposed on the housing and is connected to at least one of the cross flow fans. By this structure, longer cross flow fans having preferred rigidity and strength can be formed.
