摘要： A heat exchanger (10) is disclosed for providing heat exchange between fluids (24, 25), such asin a solar power plant (1), wherein said heat exchanger (10) comprises - a first pipe connector (13) and a second pipe connector (14), and - a pipe bundle (17) extending between the first and second pipe connectors (13, 14), wherein said pipes (17a-17n)of the pipe bundle (17) are configured to guide a second fluid (25), wherein said pipe bundle (17) is connected to the first and second pipe connectors (13, 14) at pipe connection points (16) so the inside of the pipes (17a-17n) of the pipe bundle (17) is in fluid communication with the cavities (15) of the first and second pipe connector (13, 14), and wherein pipes (17a-17n) of the pipe bundle (17) are arranged next to each other and extend together between the pipe connectors (13, 14) in a meandering manner providing a plurality of crests (20a, 20b) on the pipes (17a-17n) between the pipe connectors (13, 14), and so that crests (20) of pipes (17a-17n) of the pipe bundle (17) are arranged to extend into recesses (21) provided by one or more crests (20) on other pipes(17a-17n) of the pipe bundle (17).

摘要： A heat exchanger (10) is disclosed for providing heat exchange between fluids (24, 25), comprising a pipe bundle (17) extending between first and second pipe connectors (13, 14) and configured to guide a second fluid (25) between the first and second pipe connectors (13, 14), the pipes (17a-17n) being distributed in layers (22) of pipes (17a-17n), wherein a plurality of pipes (17a-17n) of each of said layers (22) of pipes each comprises two bends (B1, B2), so that the respective pipe provides three substantially parallel flow path sections (S1, S2, S3), wherein the length (L1) of a longer (S1) of said flow path sections of the respective pipe is at least 1.7 times greater than the length (L2) of the other two shorter flow path sections (S2, S3) of said pipe, wherein a first (B1) of said bends (B1, B2) is provided between the longer flow path section (S1) and a first of said shorter flow path section (S2), and wherein the other (B2) of said bends is provided between said first, shorter flow path section (S2) and the other shorter flow path section (S3), wherein each of said layers of pipes (17a-17n) comprises two pipe subgroups (SG1, SG2), wherein the longer (S1) of said flow path sections of one of said subgroups (SG1, SG2) is connected to a first of said pipe connectors (13, 14), and wherein the longer (S1) of said flow path sections of the other of said subgroups (SG1, SG2) is connected to the other of said pipe connectors (13, 14), and wherein the bend (B2) between the two shorter flow path sections (S2, S3) of the respective pipes in one of said pipe subgroups (SG1) in the pipe layer (22) is arranged substantially opposite to bends (B2) extending between the two shorter flow path sections (S2, S3) of pipes in the other pipe subgroup (SG2) of the same pipe layer (22).
