Heat exchanger module unit
A heat exchanger module unit that provides heat exchange between a fluid and a heat medium by indirect heat exchange through a phase-change material disposed between movement paths of the fluid and the heat medium movement paths, includes: a multiple number of plates having a partition, which is formed with a through-hole through which the fluid and the heat medium move, are stacked with a spacing gap, through which the fluid and the heat medium move, at one side of the partition; the spacing gaps are selectively connected through a connector connecting the respective through-holes so as to form a fluid passage and a heat medium passage through which the fluid and the heat medium move independently respectively; the spacing gap, in which the phase-change material is received, is located and disposed between the spacing gaps forming the fluid passage and the heat medium passage through which the fluid and the heat medium move respectively such that heat exchange is made between the fluid and the heat medium through the phase-change material. One of the fluid and the heat medium is disposed at one side of the phase-change material and another phase-change material is disposed at the opposite side thereof.
1. A heat exchanger module unit comprising:
a multiple number of plates, each of the multiple number of plates having a partition formed with a through-hole, through which a fluid and a heat medium move, each of the plates being stacked with a plurality of spacing gaps, through which the fluid and the heat medium move, at one side of the partition;
a connector configured to connect respective through-holes, the connector selectively connecting the spacing gaps of the plates through which the fluid and the heat medium move independently respectively; and
phase-change materials including a first phase-change material and a second phase-change material;
wherein the plurality of the spacing gaps is configured to include:
a fluid passage through which the fluid moves;
a heat medium passage through which the heat medium moves;
a first phase-change material gap in which the first phase-change material is received, the first phase-change material gap located adjacent to the fluid passage; and
a second phase-change material gap in which the second phase-change material is received, the second phase-change material gap located adjacent to the heat medium passage,
wherein the first and second phase-change material gaps are located between the fluid passage and the heat medium passage,
wherein heat exchange is indirectly made between the fluid and the heat medium through latent heat stored in the first and second phase-change materials,
wherein the connector includes a plurality of connection rings each configured to connect the through-hole formed in one partition of two adjacent partitions and the through-hole formed in the other partition of the two adjacent partitions and to seal the two through-holes from outside,
wherein one partition of the two adjacent partitions is configured to include a plurality of extension protrusions extending away from the other partition of the two adjacent partitions,
wherein a receiving recess in which a respective one of the plurality of connection rings is received is formed in each of the extension protrusions,
wherein the plurality of connection rings is disposed in the plurality of the spacing gaps, respectively, and
wherein the plurality of connection rings includes:
a first connection ring disposed in the first phase-change material gap and configured to seal the through-hole formed in one partition of two partitions located adjacent to each other to form the first phase-change material gap and the through-hole formed in the other partition of the two partitions from the first phase-change material; and
a second connection ring disposed in the second phase-change material gap and configured to seal the through-hole formed in one partition of two partitions located adjacent to each other to form the second phase-change material gap and the through-hole formed in the other partition of the two partitions from the second phase-change material.
2. The heat exchanger module unit of claim 1 , wherein the phase-change materials further include a third phase-change material which is received in at least one spacing gap from the outermost spacing gap among the spacing gaps of the plates.
3. The heat exchanger module unit of claim 1 , wherein the partition, which forms two rows of the spacing gaps where the first and second phase-change materials are consecutively disposed, is formed with a passage hole which allows the first and second phase-change materials to pass therethrough and to be interchanged with each other.
4. The heat exchanger module unit of claim 1 , wherein the phase-change materials are made of paraffin.
