The heat exchanger

 

(57) Abstract:

The invention is intended for use in Teleorman technique and can be used for residential heating, for cooling, for example, internal combustion engines. The heat exchanger includes a housing with an air duct, which is located a rotor in the form of a stack of disks mounted on the shaft, heat exchange surface and the collector supply and exhaust air and heat. Thus the heat exchange surface is one side of the duct, divides the field of heating and cooling and is made in the form of cylindrical shells partially covering the rotor disks, placed in a knee-shaped part of the duct, and the axis of the rotor is perpendicular to the incident air flow. The invention improves thermal capacity of the known heat exchangers, as well as to simplify the regulation of heat removal. 1 Il.

The lack of heat exchanger design is the complexity and the large area of heat exchange surface.

A prototype of the selected heat exchanger, comprising a housing, which houses the rotor disks mounted on the shaft and the channel inlet and outlet of air and heat. The rotor disks are heat-exchange surface [2].

The disadvantage of the prototype is a low rate of heat removal due to design features of the device.

The objective of the invention is to increase heat capacity at small dimensions of the heat exchanger, as well as easy control of heat removal.

The problem is solved due to the fact that the heat exchanger includes a housing with an air duct, which is located a rotor in the form of a stack of disks mounted on the shaft, heat exchange surface and the collector supply and exhaust air and heat. Thus the heat exchange surface is one side of the duct, divides the field of cooling and heating, and made in the form of cylindrical shells partially covering the rotor disks, placed in a knee-shaped part of the duct, and the axis of the rotor is perpendicular to the incident air flow.

Intensive overlay radial flow from the rotating discs on the incoming flow by placing disks of the rotor near the surface of the heat exchange.

These characteristics have been identified in other technical solutions in the radiation level of the art and, therefore, the decision is novel and involves an inventive step.

The drawing shows a diagram of the heat exchanger.

The heat exchanger includes a housing with duct 1, in a knee-shaped part of which is placed the rotor 2 in the form of a stack of disks mounted on the shaft 3 with a gap between them. The axis of the rotor in the channel of the duct is perpendicular to the incident air flow. One of the sides of the duct 1 is the heat exchange surface 4 and is made in the form of cylindrical shells partially covering the rotor disks. The heat exchange surface 4 divides the field of cooling and heating, which include the collector supply and exhaust air 5, 6, and heat 7, 8.

Does the heat exchanger is as follows.

To the heat exchange surface 4 side of the heating heat down through the manifold 7. As the heat carrier can be used hot liquid, the combustion products of hydrocarbon fuel, the heat radiation. Cold air through the manifold 5 is supplied to the rotating rotor disks 2, creating a radial component of flow, occur in maruosa on the heat exchange surface of the longitudinal (with respect to the direction of flow) vortices. On the concave side of the heat exchange surface 4 is formed of sustainable wash flow with recirculation flow in the longitudinal vortices on the surface. This provides for the transfer of longitudinal vortices heat from the heat exchange surface 4 to the inner layers of the heated air, thereby increasing the heat transfer coefficient.

The proposed heat exchanger has a large heat capacity, low material consumption, compactness and sufficient technological simplicity of manufacture.

A heat exchanger comprising a housing with an air duct, which is located a rotor in the form of a stack of disks mounted on the shaft, the axis of which is perpendicular to the incident flow, heat exchanger surface and the collector supply and exhaust air and heat, wherein the heat exchange surface is one of the walls of the duct, divides the field of heating and cooling and is made in the form of cylindrical shells partially covering the rotor disks, placed in a knee-shaped part of the duct.
