CZ308077B6 - Tubular modular exchanger for indirect heating or cooling - Google Patents

Abstract

The tube modular exchanger for indirect heating or cooling consists of sections containing the primary piping (1), which is inserted into the secondary piping (2) consisting of a cylinder with double walls, and the primary piping (1) is linked in parallel with the collectors (3) of the primary piping (1) and the secondary piping (2) are linked in parallel with the collectors (4) of the secondary piping (2) and the contact between the primary (1) and inside wall of the secondary piping (2) is modified for maximum heat or cooling transfer while detecting any escape of heat transfer medium.

Description

Technical field

The invention relates to a modular heat exchanger with sectional piping for indirect heating or cooling of liquid and gaseous substances, eg for domestic hot water utilizing waste heat from a cooling device.

BACKGROUND OF THE INVENTION

The hitherto known devices for indirect water heating utilize the hollow exchangers connected in parallel with each other, where the heating screw is provided with a cold drinking water supply at the last countercurrent hollow exchanger connected in series. Also known is a device where the primary tube is inserted in the secondary tube. The devices are complex and require temperature sensors, solenoid valves, thermostatic valves, pumps, safety valves and other elements in order to avoid contamination of the heated water by cooling water in the event of a circuit failure. An exchanger close to the contact exchanger is a double-shell contact exchanger, which consists of flattened flat tubes where they are alternately stacked side by side. The sensitivity of the primary pipeline from the secondary pipeline and the transfer of heat or cold is reduced by the smaller contact area and heat expansion of the pipeline, reducing contact between individual pipelines, replacing efficiency by increasing it, thereby increasing material consumption and weight.

SUMMARY OF THE INVENTION

The above drawbacks, in particular reduced efficiency, increased material consumption, increased weight and labor, are overcome by a tubular modular heat exchanger consisting of a primary pipe and a secondary hollow cylinder, which is based on the primary pipe from which the primary pipe is inserted. heat or cold transferred to the secondary pipe.

There must be a leak between the primary and secondary pipelines and thus the possibility of leakage from the primary or secondary pipelines. It is also advantageous for both the primary and secondary piping to be, for example, a helical liner, or otherwise made to allow greater use of heat or cold by rubbing the medium against the pipeline walls. However, the two pipelines, both primary and secondary, can be exchanged with each other, and it is still true that in the event of a pipeline failure, the medium will not blend together.

The advantage of such a modular exchanger is higher efficiency of energy transfer, its reduction, weight and material consumption minimization of soldered joints and thus the possibility of leakage of medium. The length and the number of sections can vary the power and size of the exchanger in a variable way, where it is impossible to interconnect the medium into the opposite pipeline, without securing and regulating elements.

If the exchanger is made of copper, then it is easily recyclable.

DETAILED DESCRIPTION OF THE INVENTION

Figure 1 schematically illustrates a separate section and arrangement of multiple sections of a modular exchanger in which the heat or cold flowing in the primary conduit 1 is transferred by contacting the surface to the inner conduit surface of the hollow cylinder of the secondary conduit 2. The primary conduit 1 on the header 3 of the primary conduit 1 and the parallel connection of the hollow cylinder of the secondary conduit 2 to the collector 4 of the secondary conduit 2. Fig. 3 is a sectional view of a modular exchanger. they are not separated from each other by only one wall, thus ensuring that one of the two substances cannot be contaminated. Both liquid and gaseous media such as petroleum products, alcohol, coolant and the like can be used for heating or cooling.

Industrial applicability

A modular tube heat exchanger for indirect heating or cooling of liquid and gaseous substances can be used to heat water by hot waste steam from cooling equipment such as water condensers, heat pump exchangers, industrial coolers or heaters and the like.
