Abstract

A heat exchanger includes a body having a center and a spiral guiding trough extending spirally and outwardly from the center toward an outside of the center. The radius of the spiral guiding trough increases gradually from the center toward the outside of the center. A first port and a second port are in communication with the spiral guiding trough respectively. With the combination of the spiral guiding trough and the body, the fluid can be sufficiently mixed in the spiral guiding trough, thereby achieving an excellent thermal-conducting effect.

Claims

exact text as granted — not AI-modified
1 . A heat exchanger, including:
 a body having a center and a spiral guiding trough extending spirally and outwardly from the center toward an outside of the center, a radius of the spiral guiding trough increasing gradually from the center toward the outside of the center, and   a first port and a second port being in communication with the spiral guiding trough respectively.   
     
     
         2 . The heat exchanger according to  claim 1 , wherein the first port is positioned in the center, and the second port is positioned in the outside of the center. 
     
     
         3 . The heat exchanger according to  claim 2 , wherein the spiral guiding trough has a first channel provided between the spiral guiding trough and the second channel in communication with the second port. 
     
     
         4 . The heat exchanger according to  claim 1 , further including at least one first cover for covering the body, the first cover having a tube in communication with the first port. 
     
     
         5 . The heat exchanger according to  claim 2 , further including at least one first cover for covering the body, the first cover having a tube in communication with the first port. 
     
     
         6 . The heat exchanger according to  claim 4 , wherein the spiral guiding trough is formed on one side of the body with an open side, the first cover seals the open side. 
     
     
         7 . The heat exchanger according to  claim 1 , further including a first cover and a second cover for covering both sides the body, the spiral guiding trough is formed on both sides of the body with an open side respectively, the first cover and the second cover seal the open side respectively. 
     
     
         8 . A heat exchanger, including:
 a body having a center and a spiral guiding trough extending spirally and outwardly from the center toward an outside of the center, a radius of the spiral guiding trough increasing gradually from the center toward the outside of the center, a first port and a second port being in communication with the spiral guiding trough respectively; and   at least one first turbulent unit provided on a wall surface of the spiral guiding trough.   
     
     
         9 . The heat exchanger according to  claim 8 , wherein the first turbulent unit is a protrusion. 
     
     
         10 . The heat exchanger according to  claim 8 , wherein the first turbulent unit is a trough. 
     
     
         11 . The heat exchanger according to  claim 8 , wherein the spiral guiding trough is formed with an open side on one side of the body, and a closed side on the other side. 
     
     
         12 . The heat exchanger according to  claim 8 , wherein the spiral guiding trough has a first channel in communication with the second port. 
     
     
         13 . The heat exchanger according to  claim 11 , further including at least one first cover facing the open side for covering the body to seal the open side, the first cover having a tube in communication with the first port. 
     
     
         14 . The heat exchanger according to  claim 13 , wherein the first cover has at least one second turbulent unit corresponding to the open side of the spiral guiding trough. 
     
     
         15 . The heat exchanger according to  claim 14 , wherein the second turbulent unit is a protrusion. 
     
     
         16 . The heat exchanger according to  claim 14 , wherein the second turbulent unit is a trough. 
     
     
         17 . The heat exchanger according to  claim 8 , wherein the spiral guiding trough is formed on both sides of the body with an open side respectively. 
     
     
         18 . The heat exchanger according to  claim 17 , further including a first cover and a second cover facing the two open sides for covering the body to seal the open sides. 
     
     
         19 . The heat exchanger according to  claim 18 , wherein the first cover and the second cover have at least one second turbulent unit and at least one third turbulent unit corresponding to the open sides of the spiral guiding trough respectively. 
     
     
         20 . The heat exchanger according to  claim 19 , wherein the second turbulent unit and the third turbulent unit are protrusions. 
     
     
         21 . The heat exchanger according to  claim 19 , wherein the second turbulent unit and the third turbulent unit are troughs. 
     
     
         22 . The heat exchanger according to  claim 19 , wherein the first turbulent unit is a protrusion, and the third turbulent unit is a trough. 
     
     
         23 . The heat exchanger according to  claim 19 , wherein the first turbulent unit is a trough, and the third turbulent unit is a protrusion.
