Abstract

Invention, m. used in heating and ventilation systems. The purpose of the invention is to increase the efficiency of the air heater. For this, on each side wall there are collectors of only one group of pipes. The dispensing compartment 4 of each group of pipes 2 and 3 is located at the end of the collectors 6 and 7, and the collecting compartment 5 of each group of pipes 2 and 3 is located at the opposite end of the said end of the collectors 8 and 9. The cooled water performs a cross-countercurrent movement of air. Such a construction provides an intensive heat removal at high compactness of the heater.

The invention relates to the field of heat exchange equipment and can be used in heating and ventilation systems.

The purpose of the invention is to increase efficiency by increasing heat removal.

The drawing in axonometric view shows the heater.

The heater includes a housing 1 with two groups of pipes 2 and 3 placed inside with external fins, connected each to a distribution and collecting compartment 4 and 5 of collectors 6, 7 and 8, 9, respectively, located on the side walls 10 and 11 of housing 1 and provided with overflow compartments 12, Compartments 4 and 5 are provided with water supply and discharge pipes 13 and 14, respectively. On each side wall 10 and 11 there are collectors 6, 8 and 7, 9, respectively, of only one group of pipes 2 and 3, Distributive section 4 of each group of pipes 2 and 3 is located at the end of the collectors 6 and 7 , and the collecting compartment 5 of each group of pipes 2 and 3 - at the opposite end of the mentioned end of the collectors 8 and 9, Kals

7 and 9 pass water in the right (in the drawing) group of pipes 3,

Air is supplied to the upper part of the housing 1 and, in the space between the pipes 2 and 3, are heated due to contact with them and removed heated in the lower part of the housing 1. This provides a counter-current with respect to the general direction of the water movement. The water is cooled by supplying through the dispensing compartment 4, located at the lower end of the collectors 6 and 7, and withdrawing through the collecting compartment 5, located at the opposite end of the said upper end of the collectors 8 and 9, makes a counter-current movement relative to the direction of air movement. I

This ensures, with a high compactness of the heater, intensive heat transfer, which increases its efficiency.

Claims (3)

Formula of art. 1, air heater comprising a housing yes pipe 2 and 3 heater can be zo placed inside by two groups 35 made coil, and pipes 2 and 3 are located one relative to another in a checkerboard pattern. The work of the heater is as follows. One stream of cooled water is fed through pipe 13 into the dispensing compartment 4 of the collector 6 of the left (in the drawing) group of pipes 2, from where it enters the first rotary compartment 12 of the collector 8, then again through the pipes 2 located above the first rotary compartment 12 of the collector 6, etc. At the end of the movement the water from the second rotary compartment 12 count, 4S The lecturer flows through the uppermost pipes 2 into the collecting compartment 5 of the collector 8, from where cooled water is discharged through the nozzle 14. Similarly, but using collectors 40 pipes, each of which are connected to the distributing and collecting compartments of collectors located on the side walls of the housing and equipped with reusable compartments, characterized in that, in order to increase efficiency by increasing the heat removal, only lateral collectors are located on each side wall one group of pipes, the distributing compartment of each group is located at the end of one collector, and the collecting one - at the opposite end of the other end of the other collector. 2. An air cooler according to claim 1, characterized in that each pipe is coiled. 3. Heater Popp, 1 and 2, distinguished by the fact that each pipe is made with outer ribbing.  placed inside by two groups pipes, each of which are connected to a distributing and collecting compartment of collectors located on the side walls of the housing and equipped with overflow compartments, characterized in that, in order to increase efficiency by increasing heat removal, there are collectors of only one group on each side wall pipes, distributing the compartment of each group is located at the end of one collector, and collecting - at the opposite end of the mentioned end of another collector. 2. An air cooler according to claim 1, characterized in that each pipe is coiled. 3. Heater air popp, 1 and 2, distinguished by the fact that each pipe is made with external fins.
