20030131976, Jul 17, 2003

Filed:

Jan 9, 2003

Appl. No.:

10/339313

Inventors:

Paul Krause - Clayton MI, US
Robert Utter - Adrian MI, US

International Classification:

F28D001/00

US Classification:

165/148000, 165/906000

Abstract:

A heat exchanger system having a fluid inlet member, a fluid outlet member, and a plurality of multi-port heat transfer members. Each of the multi-port heat transfer member extends between the fluid inlet member and the fluid outlet member to define a plurality of fluid paths between the fluid inlet member and the fluid outlet member for carrying a refrigerant or coolant. The plurality of multi-port heat transfer members are spaced apart from each other so as to maximize the product of the total air-side surface area and the heat transfer coefficient of the heat exchanger. If necessary for structural rigidity, at least one reinforcing member fixedly interconnects at least some of the plurality of multi-port heat transfer members in a woven pattern to provide both longitudinal and lateral reinforcement.

Abstract:

The present disclosure is directed to a mobile machine, such as hydronic surface heater designed to be transported to a potentially remote worksite and operated for an extended period of time. The machine has a fueled component, such as a burner, fueled by a fuel supply system having at least two fuel tanks that are operably connected to one another by a connection line having an electronically controlled valve therein. The valve is coupled to the machine's electrical system, such as being coupled to the output of the machine's main breaker, so as to be opened whenever the machine is operating but to be otherwise closed. The fuel supply system thus has, in effect, a single tank when the machine is running and multiple separated tanks when the machine is not running. Fuel spill risks therefore are mitigated without having to sacrifice operating time and without significantly complicating the machine's fuel supply systems or its controls.
