Embodiment Construction

[0078] figure 1 The internal heat exchanger shown in has an outer tube 11 and a cylindrically designed flow body 20 which is fitted into the outer tube 11 . Nine individual tubes 12 on a circumference are arranged axis-parallel in the flow body 20 . In the individual tubes 12 flows in the direction of arrow A a fluid flow to be cooled (hereinafter referred to as “hot” fluid flow). A cooling counterflow (hereinafter referred to as “cold” fluid flow) is directed by flow body 20 and flows in the direction of arrow B through the heat exchanger. The flow body 20 will be described in detail elsewhere below.

[0079] In order to introduce and export these cold and hot fluid flows in the cylindrical flow body 20 constituting the heat exchanger housing, two-piece connecting parts 13, 14 and 15, 16 are provided at the two ends of the flow body 20 respectively. , the fluid flows are introduced and discharged separately from one another via the connecting parts, mainly in countercurren...

Abstract

The invention relates to an inner heat exchanger for separately guiding a cooling fluid flow and a fluid flow to be cooled. In order to improve the heat transfer between the two separately guided fluid flows, a cylindrical flow body (20) is provided, comprising a convex impact surface (42) on the front end thereof. A plurality of individual tubes (12) forming a parallel tube bundle are disposed on a circumference of a circle in the flow body (20), guiding the fluid flow to be cooled. The individual tubes are located in longitudinal holes (43) of the flow body (20) extending in parallel axes, forming an annular gap (45) through which the cooling fluid flows.

Description

technical field [0001] The invention relates to an internal heat exchanger, in particular for an air-conditioning system of a motor vehicle, with a housing for separately conducting a cooling fluid flow and a fluid flow to be cooled, the fluid flows The lead-in or lead-out is through a plurality of connecting parts arranged at the end of the housing. Background technique [0002] The internal heat exchanger is used as a fuel cooler, a cooler for oil pressure lines and a heat exchanger for stationary cooling equipment. They are generally used for cooling fluid-transferring or gas-transferring media. A major application of internal heat exchangers is in motor vehicle air conditioning equipment. [0003] One possibility of increasing the efficiency of air-conditioning systems used in motor vehicles is the use of an internal heat exchanger in which the return flow of the low-pressure side and the forward flow of the high-pressure side of the refrigerant are in mutual contact w...
