Abstract: A tuning method for a collimator of a CT machine, which, in each cycle of X-ray scan operation and stop, may include determining whether an X-ray is generated from the anode plate; calculating the Z-direction heating displacement of the slot plate during the current scan based on a detected X-ray, driving the slot plate to move by the heating displacement in the Z-direction, calculating the total Z-direction heating displacement of the slot plate at the end of the current scan, calculating the cooling displacement of the slot plate during the current stop based on the stop time of the X-ray, and driving the slot plate to move.

Abstract: A heat exchanger radiating fin structure and a heat exchanger thereof. The radiating fin includes a main body and at least one rib. The main body has a first plane face and at least one lateral side. Multiple depressions are formed on the first plane face. The rib is disposed on a portion of the first plane face, which portion is free from any of the depressions. The rib obliquely extends in a direction neither normal nor parallel to any lateral side of the first plane face. The heat exchanger includes a radiating fin assembly composed of multiple piled up radiating fins. Each two adjacent radiating fins define therebetween a flow way having at least one inlet and at least one outlet. With the depressions and the rib, the structural strength of the radiating fin is increased and the heat exchange performance of the heat exchanger is enhanced.

Abstract: A heat exchanger includes an enclosure internally providing at least a first space and at least a second space; a first forced convection element and a cooling unit arranged in the first space; a second forced convection element and a vaporization unit arranged in the second space; and a heat transfer unit serially connecting the cooling unit and the vaporization unit to form a loop. The first and the second forced convection element work to enable forced convection of airflow, and the vaporization unit and the cooling unit together with the heat transfer unit form a convection unit. As a result, the heat exchanger has largely upgraded heat exchange efficiency.

Abstract: A heat exchanger includes a body. Both sides of the body are provided with a first flowing path set and a second flowing path set. The first flowing path set and the second flowing path set are provided with a plurality of flow-disturbing portions on both sides of the body respectively. The body is provided with an inlet and an outlet in communication with the first flowing path set and the second flowing path set. A working fluid circulates in the first flowing path set and the second flowing path set. The flow-disturbing portions make the working fluid to generate separated eddies to increase the strength of turbulent flow and to improve the heat-conducting efficiency of the heat exchanger greatly.

Abstract: A reinforced thermal module structure includes a radiating fin assembly, a radiating base, and at least one heat pipe. The radiating fin assembly consists of a plurality of stacked and spaced radiating fins, each of which has at least two notches. The heat pipe includes a conducting section in contact with the radiating base, and a heat-dissipating section extended through the radiating fin assembly to connect thereto. The radiating base has at least two support arms for correspondingly engaging with the at least two notches on the radiating fins. The support arms help in enhancing the structural strength, heat conducting efficiency, and heat-dissipating effect of the thermal module structure.
