Electric fluid heater for a vehicle, including a heating block with an inlet and an outlet for the fluid, a first channel for the fluid intended to flow between the inlet and the outlet, a first tube and a second tube with opposing ends mounted in headers, the tubes having heating elements. The first channel is delimited by a top plate and a bottom plate sealingly connected to the first tube, the second tube and the headers.

A portable pest eradication system 60, comprising a plurality of electrical cords 21a-e connected electrically to a plurality of the electric heating elements 65a-e, a circulation fan assembly 55, a programmable module 48 and a user interface for entering a treatment time and/or a target temperature for heating a particular room in a house or building. The portable pest eradication system 60 is designed to provide sufficient heat to reach the target temperature in a reasonable period of time to kill bedbugs, bedbug eggs, mold, ticks, bacteria, dust mites, scabies, cockroaches, body lice, fleas, and/or other pests.

Disclosed is a heating device, including a housing, and an electrothermal film and a fan arranged in the housing, wherein the fan is located at a bottom of the electrothermal film, the fan is provided with an air inlet facing upwards and an air outlet facing forwards, and the housing is provided with a vent hole at a position corresponding to the air outlet.

Some embodiments of the present disclosure provide an electric heater, which includes: a housing provided with an air inlet and an air outlet, and the housing internally having an air duct communicated between the air inlet and the air outlet; and a heating member and a convection member both being assembled in the air duct, wherein the heating member being configured for heating the air entering from the air inlet to the air duct during energization, the convection member being configured for blowing a heated air from the air duct to the air outlet for discharging. Herein the air outlet is provided on a bottom end of the housing close to a ground.

A PTC heater including: a PTC element heating part configured to generate heat; and a pair of heat dissipating plates disposed at two opposite sides of the PTC element heating part, respectively, so as to be in contact with the PTC element heating part and having a plurality of flow holes, in which the heat dissipating plates have heat dissipating fins each connected to one side of each of the flow holes and bent to a space between the heat dissipating plates.

A battery operated hair dryer includes a battery management and control module to control how to efficiently dry a user's hair while maintaining the health and charge of the battery.

A hybrid light and fan fixture includes a plurality of LED lights surrounding a fan and its motor within a housing. A connector is made to allow the hybrid fixture to be installed in a conventional light socket for 110v electrical power. An alternative embodiment includes either or both features of a set or rotatable deflector blades and a serpentine heating element to more positively influence the air flow created by the fan and make the air stream more effective in de-fogging the mirror. Preferably, the fixture includes a circuit that allows the lights to be energized with and without the fan and heating element.

A cabin heater for a vehicle includes a frame with spaced apart longitudinal supports to locate a common electrical return and a power input. Pluralities of heating units extend between the supports and attach to the return and input. Each unit has a ceramic heater and one or more positive temperature coefficient (PTC) elements. The ceramic heater quickly and directly heats air and helps lower the inrush current of each PTC element upon initial powering. The power input also includes conductive rails spaced apart and electrically isolated from one another to individually supply power to either the ceramic heater or the PTC elements, but not both. Conductive extensions pass through the rails and fold into contact to power either the heater or the PTC elements. The electrical return commonly attaches the PTC elements and the heater, including a spring connection.

A snow, ice and debris removal device is disclosed. The multipurpose device includes a handle, a cylindrically-shaped forced air blowing system and a plurality of controls. The cylindrical shaped forced air blowing system features a front opening for expelling cool or heated air, which is adjustable via a switch to suit the application for which the device is being used. The forced air blowing system comprises an internal induction heating/cooling coil that heats or cools the air expelled through the system. When the switch is set to hot air mode, the device expels a stream of heated air which the user can easily direct at snow and ice accumulations on, for example, a sidewalk, driveway, parked vehicle, etc. or to dry a surface. Alternatively, when the cool air mode is selected, the device expels a stream of cool air that the user can use to displace leaves and other debris.
