A heat insulating vessel including an inner tank having a vertical axis to accommodate low temperature liquefied gas, an outer tank externally around the inner, and a low temperature liquefied gas pump disposed inside the inner tank. The outer tank having an upper part and an outer tank body. A lid structure having a heat-insulated structure detachably fitted into an upper part of the inner. The heat insulating vessel includes a first fastener to fasten with bolts, a first flange to upper ends of the inner and outer tanks upper part to a second flange to an outer circumferential part of the lid structure, and a second fastener to fasten with bolts, a third flange to an upper end of the outer tank body to a fourth flange to a lower end of the outer tank upper part. A vacuum insulating layer is formed between the inner and outer tanks.

A pump assembly is presented including a motor housing holding an electric motor and a wet-end housing. The pump assembly also includes a heat transfer interface positioned between a front end of the motor housing and the wet-end housing. The heat transfer interface establishes a thermal conduction path between the motor housing and the wet-end housing so that, in use, a portion of heat generated by the motor is absorbed by the heat transfer interface and is dissipated in water circulating through the wet-end housing. In addition, or alternatively, another thermal conduction path may be established between the heat transfer interface and an electronic controller of the pump assembly so that heat generated by the controller is absorbed by the heat transfer interface and dissipated in water circulating through the wet-end housing. Mounting brackets may be provided at different radial locations about an outside casing of the pump assembly to allow mounting the assembly to a supporting structure in different orientations.

An automotive electrical gas pump includes an electronically commutated motor which drives a motor rotor to rotate within a motor can. The motor has a motor stator which comprises at least one static electro-magnetic coil. An electronic circuit board drives the at least one electro-magnetic coil. A mounting frame includes a motor can and a stator bed. The stator bed embeds the motor stator at least in part. The mounting frame is made of a plastic material which includes a thermally high-conductive filler material.

An electric coolant pump includes a pump housing, an electric motor, and a pump wheel. The pump housing has a pumping chamber and a motor chamber which are separated by a separation sidewall. The pumping chamber has a pump volute which extends from a pump inlet to a pump outlet. A volute cooling sector of the pump volute extends over a volute angle of 120°. The separation sidewall has a cooling section which is defined by the volute cooling sector. The electric motor includes a motor rotor, a motor stator having a stator coil arrangement, and a motor electronics arranged in the motor chamber which energizes the stator coil arrangement. The pump wheel is arranged in the pumping chamber and is connected with the motor rotor. The stator coil arrangement is arranged adjacent to the volute cooling sector and thermally contacts the cooling section of the separation sidewall.

An electric water pump with a control panel mounted in the middle of the water pump is disclosed, including a water pump volute casing, a water pump impeller, a pump cover, a water pump control panel, a rotor, a rotor cover, a housing, a rear bearing, a stator, a thrust ring, and a front bearing. The water pump volute casing is mounted on a surface at a front end of the pump cover. The water pump control panel is mounted on a surface at a rear end of the pump cover. An end opening of the rotor cover is sleeved on an outer circumference of a boss at the rear end of the pump cover.

Provided is a fluid pump assembly. The pump has a pair of housings magnetically coupled to each other. The first housing contains a drive motor and a magnetic assembly. The second housing contains a magnetic assembly and a blade for imparting movement to a fluid. As the first magnetic assembly is rotated by the drive motor, the magnetic connection to the assembly in the second housing causes the second magnet to rotate, driving the blade.

A heat insulating vessel for a low temperature liquefied gas pump, which includes an inner tank configured to accommodate low temperature liquefied gas, an outer tank provided externally around the inner tank, and a low temperature liquefied gas pump disposed inside the inner tank. The outer tank has an outer tank upper part that is an upper end portion thereof, and an outer tank body other than the outer tank upper part. A lid structure having a heat-insulated structure detachably fitted into an upper part of the inner tank. The pump is fixed to the lid structure, and a suction pipe and a discharge pipe are insertedly fixed to the lid structure. A vacuum insulating layer is provided between the inner tank and the outer tank. With this heat insulating vessel for the low temperature liquefied gas pump, adiabaticity of the lid structure and maintainability of the pump are increased.

An electric pump includes a pump housing, a rotor assembly, a stator assembly, an isolation sleeve, a heat dissipation plate and an electric control board. The pump housing defines a pump inner chamber; the pump inner chamber is partitioned into a first cavity and a second cavity by the isolation sleeve; the rotor assembly is disposed in the first cavity; the stator assembly and the electric control board are disposed in the second cavity; the isolation sleeve comprises a bottom portion; at least a portion of the heat dissipation plate is disposed between the electric control board and the bottom portion; at least a portion of the bottom portion and at least a portion of the heat dissipation plate are in direct contact, or are filled with thermal silicone grease or thermal silica therebetween, or are provided with a thermal patch therebetween.
