The invention relates to solar engineering, namely to devices for heating water by means of solar energy, and can be used for heat supply of residential, urban and industrial buildings and municipal facilities.

A solar energy collector l for heating water 1 is known, in which the thermal detector of solar energy contains a radiation-absorbing plate and heat-removing pipes welded to it.

The disadvantages of the collector are the complexity of manufacturing and low corrosion resistance.

A device for absorbing solar energy 2 is also known, comprising a beam-absorbing plate and a heat transfer channel attached to the plate by means of a locking element.

A disadvantage of the device is its low corrosion resistance, as well as low operational reliability due to the specific thermal contact between the elements of the lock and the channel for the heat carrier.

The purpose of the invention is to increase the operational reliability of the device.

This goal is achieved by the fact that in a flat-tube absorber containing a ray-absorbing plate and at least one drip for the heat carrier is attached to the plate by means of a locking element (E, the channel is made of a plastic tape that is rolled up on the cable, the edges of which are provided with collars clamped by a cereal element, the latter is provided with a heat sink rib inserted into the channel cavity through a gap formed by a plastic tape rolled into a tube.

In FIG. 1 shows a general view of a flat-tube absorber of solar energy; in FIG. 2 is a diagram illustrating the connection of a beam-absorbing plate with a stepping channel.

The flat-tube absorber of solar energy comprises a housing 1 with a translucent fence 2 and a heat receiver installed therein from a metal beam-absorbing plate 3 with heat-removing channels 4;

A lock 5 with a heat-removing element 6 is welded to the beam-absorbing plate

on the sides 7, the heat sink channel is formed of a deformable plastic tape 8 with collars 9 along the edges.

The heat sink channel with the radiation absorbing plate is connected as follows

way. The plastic tape 8 is folded into a tube and the collars 9 are inserted into the groove of the lock, after which the sides of the lock are rolled up to complete tightness.

Flat tube absorber working

in the following way.

The sun's rays, incident on the beam-absorbing plate 3, heat it, while the lock 5 is also heated with a heat-releasing element 6, which transfers heat to the heat carrier flowing through the heat-conducting channel 4,

The removal of the heat sink channel from plastic materials increases the corrosion resistance and reduces the metal consumption of the collector, which is 2 times lower than that of the prototype. At the same time, the service life of the proposed collector increases approximately 3-4 times. In addition, thermal

losses through the bottom of the collector due to the insulating properties of the material of the heat sink channel. This leads to an increase in efficiency of 3-5%. The claims A flat-tube absorber comprising a beam-absorbing plate and at least one heat carrier kayal attached to the plate by means of a locking element, characterized in the fact that, in order to increase operational reliability, the channel is made of a plastic tape which is rolled up into a tube, the edges of which are provided with collars clamped by a locking element, the last equipped with a heat sink rib inserted into the cavity of the channel through a gap formed by a plastic tape rolled into a tube. 1
