Title: Innovations of Matthew William Critchley

Introduction

Matthew William Critchley is a notable inventor based in Milwaukee, WI (US). He has made significant contributions to the field of engineering, particularly in the development of innovative technologies related to water heating and fluid flow measurement. With a total of 7 patents to his name, Critchley has demonstrated a commitment to advancing practical solutions in his industry.

Latest Patents

One of Critchley's latest patents is for a leakage detection system in condensing water heaters. This innovative water heater system includes a gas burner that selectively produces flue gases and a heat exchanger for heating water. The system operates in both heating and standby modes. It features an exhaust assembly that communicates with the heat exchanger, including a condensate collector designed to receive flue gases and condensate. A first temperature sensor is strategically positioned to sense the temperature of the condensate within the collector. This sensor detects the rate of temperature change, allowing a controller to determine leakage when the temperature change rate shifts from one state to another during standby mode after heating.

Another significant patent involves a flow sensor with a hot film anemometer. This method determines flow velocity in a defined flow path for a fluid moving downstream. A thermally-conductive element is exposed to the flow path, where a known amount of heat is applied to one portion of the element. The temperature is then sensed at a downstream portion, allowing for the calculation of the fluid's flow velocity based on the known heat and sensed temperature.
