A guiding grid is disclosed and includes plural circumferential elements and plural radial elements. The circumferential elements are disposed concentrically relative to a central axis, spaced apart from each other in a radial direction, and form different heights relative to a bottom surface. One of the circumferential elements forms a top height relative to the bottom surface, so that the circumferential elements are divided into an outer-ring region and a central region in the radial direction. The circumferential elements located in the central region are increased in height relative to the bottom surface along the radial direction. The circumferential element located in the outer ring region are reduced in height relative to the bottom surface along the radial direction. The radial elements are connected between each of two adjacent circumferential elements. At least one of the radial elements is misaligned and discontinuous in the radial direction.

Guiding grid

A partition of an electrical connector has a body and two extensions. The body has two outer sides opposite to each other. The extensions respectively connected to the outer sides of the body. Each of the extensions has a first bent leg, a second bent leg and an axis Each of the extensions is bent along the axis to stack the second bent leg on the first bent leg. Therefore, the thickness of the partition is increased to enhance the structure of the tongue, so that the stability of the electrical connector is enhanced.

Electrical connector and a partition thereof

A multiple-motor blower includes a housing and a plurality of motors. The housing has a common outlet passage and different inlet passages. The motors are accommodated in the housing and respectively drive impellers to generate airflow flowing from the inlet passages to the outlet passage. Each of the impellers includes a hub and a plurality of blades mounted around a circumference of the hub. A ratio of a distance between adjacent two of the blades to a thickness of the blade in at least one of the impellers is smaller than or equal to 3.

Multiple-motor blower and impeller thereof

Wind turbine

A cowling of the invention includes a cover body and an empennage connected with the cover body. The cover body includes an accommodating space for receiving an impeller, and a first opening serving as an air inlet for the impeller. According to the wind direction, the empennage will adjust the first opening to the proper position to face the wind.

Cowling

A blower includes a housing and a plurality of impellers. The impellers are disposed in the housing, and a mutual air-gathering passage is formed between the impellers and the housing. Compared to the prior art, the mutual air-gathering passage of the blower of the present invention can collect the airflow and stabilize the airflow. Thus, the air pressure at the air outlet is increased, and the overall airflow performance is improved.

Blower

An axial fan is provided. The axial fan includes a base, a rotor, a guide and a plurality of blades. The guide connects to a guide tube to provide airflow. Each blade has a passive part and an active part, wherein the passive part is driven by the airflow from the guide to rotate the active part synchronously. The axial fan increases air quantity and decreases air pressure to provide efficient heat dissipation.

Axial fan

A fan system includes a first airflow generator providing a main airflow, a duct having a first feeding port to guide the main airflow, and a first fan. The first fan includes a base, a rotor connected to the base by a shaft, and a plurality of blades connected to the rotor. Each blade includes a passive part corresponding to the first feeding port and an active part. The main airflow drives the passive part rotating about the shaft to synchronously rotate the active part, dissipating heat from a heat source, increasing flow rate of airflow and decreasing pressure. The amount and location of the fans can be flexibly configured.

Fan system

A heat-dissipating device includes a housing having at least one opening, and a rotor disposed in the housing and having a base, a hub, a first set of blades disposed around the hub, and a second set of blades disposed on the base for increasing air volume and stabilizing a blast pressure of airflow passing through the heat-dissipating device.

Heat-dissipating device

A heat-dissipating device includes a housing having an air inlet and an air outlet, and a rotor disposed in the housing and having a first set of blades, wherein the housing has a sidewall extending inward from the air inlet to define an air-gathering chamber in the housing, and a plurality of air-guiding members disposed along the sidewall for increasing and stabilizing a blast pressure of airflow passing through the heat-dissipating device.

A heat-dissipating device includes a housing having at least one air inlet and at least one air outlet, and a rotor disposed in the housing, wherein the housing has a first extending part extending along an axial direction of the heat-dissipating device to form an axially compressed air passage inside the housing for enabling the airflow to smoothly flow in the air passage inside the frame thereof so as to enhance its performance.

A heat-dissipating device includes a housing having a first frame and a second frame, and a rotor disposed in the housing, wherein the first frame includes a bearing tube for accommodating a first bearing therein and the second frame includes a support for accommodating a second bearing therein so as to jointly support a shaft of the rotor. The heat-dissipating device utilizes a two-side way for securing its rotating shaft so as to enhance the stability and eliminate the vibration while operating at high rotation speed.

A heat-dissipating device includes a housing having an air inlet and an air outlet, and a blade structure disposed in the housing and having a hub and a plurality of rotor blades. The housing has an inwardly extending sidewall to define an accelerating airflow passage between the sidewall, the hub and the rotor blades for effectively increasing the airflow pressure and stabilizing the discharged airflow.
